Asta/Biography

As infants, Asta and Yuno are left at the doorstep of a church in Hage. Since then, they spend their childhood in the church with the other orphans.

One day, during their trip home from grocery shopping, Asta overhears a couple of villagers coveting the lifestyle of those who live in the Noble region. On this day, Asta learns of the discrimination that the people of the Forsaken Region receive and reveals his intention to be the Magic Emperor for the first time.

Sometime later, Asta sees a thug snatch Yuno's necklace and immediately steps in to get his friend's item back. His endeavor is a success, but the young orphan is left with injuries all over his body. Fortunately, Sister Lily of the church is able to heal him with her magic.

One day, Asta and Yuno go into the forest of Hage and stand on top of a hill while they face towards the Noble Region. Asta then starts talking about their relationship as a family, despite their lack of blood connection. Yuno agrees with Asta and asks him the reason behind the latter's sudden allusion. Asta then makes another promise with Yuno: they will treat their future comrades as a family just like the way they treat each other.

Asta and Yuno also practice their magic from time to time with Asta usually tries to break through Yuno's Wind Magic attacks. Yuno tries to convince Asta to stop as the latter fails every time. Unfortunately, the latter refuses to give up and continues his charge towards Yuno. Finally, at one point, Asta manages to break through Yuno's magic and lands an attack. He then subsequently tells Yuno that his persistence is the source of his success.

Years later, Asta confesses to Sister Lily, but is quickly rejected. He insists even after she forcefully silences him. He finally stops his approach when Yuno interrupts him. After many failed attempts to show his skills while Yuno overshadows him, Asta storms away to train on his own.

A few days later, a Grimoire Acceptance Ceremony is held in a tower near Hage. Asta fails to receive his grimoire and Drouot suggests for him to try again next year. Later in the evening, Asta is still left in a daze after Yuno also brushed off his declaration of rivalry. In the distance, while he hangs on a tree branch, Asta sees that Yuno is in trouble and quickly runs to save him. However, because of his lack of magical power, Asta is cornered by Revchi Salik who is armed with a grimoire.

Unable to retaliate, Asta submits as his spirit is shaven off by Revchi. He manages to regain his will to fight, however, after Yuno reveals his respect for Asta during their time as children. Asta then tries to get back on his feet when a grimoire suddenly flies towards Asta and gives him a sword. Using his newfound sword, Asta defeats Revchi and reinforces his promise with Yuno.

Six months later, Asta attends the Magic Knights Entrance Exam, where he meets Yami Sukehiro, Finral Roulacase, and Gordon Agrippa for the first time. During the exam, Asta is unable perform the first task given to him, which attracts Sekke Bronzazza who plans to take Asta's poor performance to his advantage. At the end, during the combat test, Sekke asks Asta to be his partner, which the latter gladly accepts. Sekke then condescendingly reveals his reason behind his decision to have Asta for his partner. Nevertheless, Asta quickly defeats him and reveals his intention to become the Magic Emperor.

Unfortunately, because of his use of unfamiliar magic, none of the captains want to recruit him. The captain of the Black Bull squad then steps in to test Asta's determination. The young orphan manages to impress Yami and he is offered a place in his squad. He then travels to the squad's headquarters via Spatial Magic and introduces himself to the other members of the squad.

One of the members, Magna Swing, decides to give Asta an initiation test to prove his worth for the squad. Asta impresses Magna when he deflects Magna's attack back towards him. Additionally, Magna remains impressed of his ability, even when Asta reveals his lack of magical power. The young Knight is then congratulated by the other members before he receives his robe while Vanessa Enoteca brands his headband with the squad's insignia.

After the test, while being taken on a tour of the headquarters, Asta meets Noelle Silva, whom is the other new member of the squad. He tries to be friendly with her, but the latter completely rejects Asta's good intention as she mentions her royalty status. Afterwards, Magna takes Asta to the latter's personal quarter. The notion of having his own room, deeply excites Asta as he started cleaning every corner of it before he goes to sleep.

Later at dawn, Asta finds Noelle while she practices on her own. Suddenly, he witnesses her magical power goes out of control. Yami who quickly arrives at the scene, orders Asta to stop her magic as he throws the young Knight towards Noelle. Asta is able to save him with the use of his Anti Magic and lands safely on the ground with Finral's assistance. He then begins to praise Noelle's ability while also encourages her to grow stronger.

During meal time, Asta asks about the duty of a Magic Knight, which Magna chides him for his ignorance. However, after he heard his squadmates' interpretation of their duty, Asta simply concludes that they are all weird. Later on, Magna reveals to Asta and Noelle that their first mission will be a boar hunting in Sosshi. Asta rejects the mission at first, but quickly accepts it as he is threatened by Yami. The three of them then travel to the village on Magna's broom, because Asta cannot ride one himself and Finral is unable to transport them with his magic. Upon their arrival, they discover that the village is covered in mist, which Magna quickly asks Asta to cut a path for them. The moment the reach the center of the village, they find the villagers are held hostage by a group of mages, led by Heath Grice. Once Magna saves the villagers, Heath launches a second attack, which Asta countered with his sword before he confronts Heath for his actions.

Asta begins his assault while he tries to uncover Heath's true purpose. Unfortunately, Heath's answers quickly infuriate him and causes Asta to proclaim that he will protect the villagers from him. Heath and his group launch a combination spell that keeps Asta and Magna occupied and unable to protect the villagers. Fortunately, Noelle casts a protection spell that shields all of them from their attacks. Asta quickly dashes towards Heath as soon as he sees an opening, but he fails to give an effective damage because of Heath's had dampened Asta's momentum by freezing his standing ground.

He then begins to receive a lot of damage from Heath, but still manages to regain his stance. Subsequently, Magna steps out of Noelle's spell and asks Asta to redo their initiation ceremony. Their strategy succeeds, and Asta quickly delivers the final attack and defeats Heath.

Asta faints as soon as Heath is defeated, but he immediately is awoken by an anti-bird, which followed him from the entrance exam. When Asta sees the Anti-bird carrying a stone, which belongs to the village's chief, he tries to have it returned but the villagers decide to give it to him. After that, Asta witnesses Heath commit suicide to protect his retainer's information, which deeply shocks him.

Asta later runs around with the anti-bird constantly pecking him while being followed by Noelle. He then has a chance meeting with Nick, the chief's grandson, to whom he gives words of encouragement.

Having returned to the headquarters, the three Knights report back to Yami who praises them for their work. Yami then gives them their salary, which quickly excites Asta. Vanessa subsequently offers Asta and Noelle to go on a shopping trip to Kikka. As they arrive, Asta becomes excited with the new experience and wishes he could take the Hage villagers with him. After they are finished with their errands, Vanessa takes both of them to the castle town's black market, where Asta spots Magna at the casino.

Additionally, the young Knight encounters Sekke who tries to flirt with Vanessa and Noelle. A conversation later, a thief snatches an old lady's bag, so Asta quickly chased and immobilized him before Sekke delivers the final strike. Unfortunately, Sekke finds himself paralyzed and attempts to give his final words, but Asta quickly stopped and motivated him before Sekke learns from Vanessa that he is fine. Asta returns the bag to the old lady and leaves with his squadmates.

Sometime later, Yami informs Asta and the other Black Bull members about the appearance of a new dungeon. The Black Bull captain then explains that the Magic Emperor has requested Asta to explore it, which quickly excites the latter, even though he knows nothing about dungeons. He then travels to the dungeon, which is located at the edge of the Kingdom, along with Noelle and Luck Voltia. As they enter, Asta argues with Noelle about the name of the anti-bird. The arguments settles immediately after Luck suggests the name for it. Immediately after, Asta drops their source of light, which caused them to walk in the dark before they reach the inner-side of the dungeon.

Asta then accidentally activates a trap when he whines about his inability to sense mana within the dungeon, but he is able to easily handle it. Asta and Noelle, however, face against numerous other traps, as Luck playfully activated all of them before he leaves them on their own. Another trap quickly emerges and immobilizes Asta. However, Yuno arrives at the scene and effortlessly saves him.

Asta and Yuno's reunion is quickly being set aside when Yuno's senior, Klaus Lunettes, begins a conversation with the Black Bull members where he believes that saving them is unnecessary. Asta and Klaus then start a series of arguments with Noelle and her cousin, Mimosa Vermillion, on their respective sides. At the end, Asta is unable to give an answer when Klaus asks them the whereabouts of Luck and the arguments begins to move towards the reputation of their captains. As the Golden Dawn members leave to conquer the dungeon, Asta and Noelle also begin their search for the center of the dungeon. Noelle starts to question their searching method, because none of them possesses a magic that could help them. Moments later, Asta sees Nero take off and point them to a tunnel.

They decide to follow Nero's guidance, but left stranded in an area with a gravitational anomaly where Asta finds a treasure chest with living organs inside it. They continue in their search for the center of the dungeon when Asta suddenly stops after he heard a peculiar noise. Noelle infers the possibility of it being the sound from Luck's fight. Asta quickly suggests that they assist him, but Noelle argues by saying that their current priority is to conquer the dungeon. However, Asta decides to help Luck and manages to negate a spell that is about to kill the latter. When Luck's opponent, Lotus Whomalt, asks for Asta's identity, the latter simply says that he is Luck's comrade.

In contrast, Luck refuses Asta's help and charges towards the opponent. However, when Lotus is about to counterattack him, Asta interferes as he ignores Luck's request. Luck finally agrees to fight the Diamond Kingdom's mage together, but the opponent immediately traps them within a shroud of thick smokes. Asta tries to cut the smoke multiple times, but he quickly grows anxious due to its unlimited amount. As soon as Luck notices something after he remarked their opponent's sensory ability, he launches a barrage of lightning-based spell attacks to guide Lotus at a certain direction while Noelle prepares to launch Asta towards him with her spell. Asta then delivers a wide swing at Lotus and the latter remarks that he had never encounter an opponent without magical power.

Lotus then escapes along with his injured subordinates and Asta fails to pursue him. Luck then suggests that they return to the main objective and head to the center of the dungeon. Upon arriving, Asta quickly activates his magic and saves Yuno from an attack. He then starts arguing with Yuno about the latter's circumstances but decides to stop and joins the fight.

The fight begins as Mars creates multiple clone puppets with his magic. While Asta is able to easily destroy the puppet, the rest of the Black Bull and Golden Dawn members have a tougher time against them. Mars tries to launch another attack after he recreated the sword that was destroyed by Asta, but the latter easily cuts it apart. Asta then quickly dashes towards him and manages to break his armor and blow him away into the surrounding pool.

However, Mars quickly prepares another attack by covering himself with an even larger armor. Mars' attack, through the said armor, is able to give Asta a significant damages but the latter is still able to hold it together while sharing his ambition to protect. Mars tries to ignore him and launches another attack, but Asta manages to break through it and render him unconscious.

After Klaus restrains Mars with his magic, the Clover Kingdom's Magic Knights finally enter the center of the dungeon as Asta cuts down the door to the treasury. They are immediately in awe with the sight of treasures stored behind the said door. Asta quickly dashes in and starts tinkering with various magic tools within. Until Nero forcefully lead him to a wall with a similar locking mechanism as the treasury door, albeit smaller, attached on it. Nero then starts pecking on his head when Asta expresses his lack of understanding of Nero's hints. Suddenly, Mars barges into the treasury and manages to land a critical damage on Noelle.

As soon as Asta sees it, he immediately charges towards the Diamond Kingdom's mage, but is easily overpowered by Mars' new fighting strategy. The latter also manages to send Asta flying through the wall that Nero was showing him. Feeling helpless and unable to find any solutions to counter Mars, Asta sees Nero flying pass him and further into the hidden room behind the wall. When Asta turns his head, he sees Nero landing on top of a sword covered in dirt. Asta quickly grabs the sword and manage to save both Mimosa and Noelle just in time from Mars' incoming attacks.

He then rushes towards Mars and is able to land an attack but Mars' healing spell is preventing Asta from giving him a significant damage. Suddenly, Noelle finally regains her consciousness after Mars attacked her and immediately orders Asta to end the fight. Asta accepts her request and throws a slash to defend himself against Mars' incoming attacks. However, to his surprise, a stream of water is coming out of his sword as he neutralizes Mars' attacks.

The stream of water manages to hit Mars but Asta, unfortunately, is unable to completely stops Mars' previous attack as a blade pierces his stomach. Asta then falls to the ground as he loses his consciousness. After Yuno defeats Mars in an instant, Asta's newfound sword suddenly enters his grimoire with unknown writings appearing on the pages.

Subsequently, the dungeon begins to collapse and the fainted Asta is immediately taken by Luck as Yuno prepares a vessel for them to escape. Before he completely loses his consciousness, Asta tries to reason with Klaus on taking Mars with them. Unfortunately, they fail to fulfill Asta's wish and head towards the exit. As soon as they are outside, Asta is taken to a safer place for Mimosa to continue her healing process. The moment Asta awakes, Klaus quickly hugs him alongside Yuno as he acknowledges the two orphans.

After the mission, Asta fell asleep for a week before he is awaken and given an order to give his report regarding his mission to the Magic Knights headquarters. When he arrives with Noelle, the couple meet with Klaus, Mimosa, and Yuno where all of them head to the designated venue together. As they arrive, the five of them are welcomed by the Magic Emperor himself as the latter then examines the magic that Asta and Yuno manage to take from the dungeon. Asta shows the Emperor the writings that appear on his grimoire while also presenting the sword that could be summoned from it. Subsequently, he asks the Emperor about the method they should use to become the Magic Emperor in which the latter gives them an interesting answer.

Asta, along with the others, are then invited by Julius to attend a War Merits Conferment Ceremony that honors Magic Knights with the best achievements. As soon as the ceremony ends, Asta then attends a banquet in which he quickly enjoys the fine dishes served while ignoring the scrutiny by the honorary Magic Knights. However, once those Knights start insulting Klaus, Yuno and Mimosa, Asta begins to lose his composure. The latter reaches boiling point when Noelle is humiliated by her own siblings in which he then declares that he will silence all of them by becoming the Magic Emperor.

Asta's confrontation is not received well by the honorary Knights as Nebra Silva, Alecdora Sandler, and Solid Silva try to put him in his place. Using his Anti Magic, Asta swiftly manages to neutralize all of their attacks until Nozel Silva, captain of the Silver Eagle, decides to enter the fray. Nozel's intense burst of magical power reminds Asta of Yami's own burst of magical power during his entrance exam to the Magic Knights as it sends chills to his body.

Luckily, Fuegoleon Vermillion, captain of the Crimson Lion, stops Nozel from acting even further while his brother, Leopold Vermillion, declares Asta as his rival. Not long after, someone enters the hall of the banquet and warns the Knights that the Royal Capital is under attack. After the sudden announcement, Asta then joins his fellow Knights as they discuss their strategy for counterattacks. However, he immediately leaves them as he expresses that they are taking too long while the citizens are being attacked.

Not long after, Asta manages to find the perpetrator of the invasion, Rades Spirito, as he defeats all of his opponents along the way. When he arrives, Asta immediately proclaims that he will protect everything that Rades wishes to destroy as he also manages to secure a little girl from the man. Hearing Asta's determination, Rades summons more corpses to attack Asta but the boy is able to easily immobilize all of them. However, when Asta charges towards him, Rades summons a different and more powerful corpse, No.4 - Jimmy.

After "Jimmy" manages to scratch Asta's face with one of his Magic Bullets, Rades reveals that the bullets are composed of curse power as Asta begins to bleed from it. Rades then proceeds on ordering "Jimmy" to unleash a barrage of attacks on Asta but the latter is able to easily defend himself. Seeing this, Rades orders "Jimmy" to shift its attention on the little girl behind Asta. The latter immediately steps in front of her as he is forced into the defensive, trying to prevent any of the bullets on hitting her.

A bullet managed to scratch Asta on his side as he begins to bleed quite extensively. The said wound distorts Asta's concentration as several bullets are about to hit the little girl. Luckily, Noelle enters the fray and takes over the duty to protect the little girl. Asta immediately charges towards "Jimmy" but Rades summons a number of corpses to prevent his advancement. However, Asta is able to go past them as Leopold assists him by burning all of those summoned corpses. While having both swords at hands, Asta manages to take "Jimmy" down and challenges Rades for a fight.

Unfortunately, his opponent did not take his challenge and summons another corpse, No.2 - Alfred. Asta quickly struggles in the fight against "Alfred" as the corpse is constantly discharging lightning attacks and preventing him from closing the distance. As his wounds from his fight against "Jimmy" are getting worse, Asta is finally at the point where he is unable to evade "Alfred"'s attack. Luckily, Fuegoleon intercepted the attack by incinerating the corpse before taking over the fight from Asta.

After hearing that Fuegoleon is acknowledging him, Asta tried to continue his fight before being stopped by the former. The Crimson Lion's captain then asks Asta to watch and learn from his fight against Rades. Seeing a captain fighting in front of his eyes, Asta is quickly being amazed by Fuegoleon's charismatic act of intimidating his opponent while raising his allies' morale.

After the fight is over and Fuegoleon has restrained Rades, Asta begins to talk to the captive about his approach of getting acknowledgement over his talents. A moment later, Asta hears a faint voice coming from Rades' direction before Fuegoleon is suddenly teleported away from them. While Noelle is trying to locate the perpetrator, Asta quickly charges towards a pile of corpses and smashes it apart and sees Valtos, the Spatial Magic user, come out of his hiding place. The man opens another portal, from which drops the body of Fuegoleon, quickly filling Asta with shock and anger.

While trying to push his confusion over Fuegoleon's defeat to the back of his head, Asta quickly prevents Rades from escaping by nullifying Valtos' Spatial Magic spell. He then manages to cut Rades' face before engaging in a fist fight against him. However, reinforcements for Rades and Valtos arrive as they surround the Clover Kingdom's Knights. Seeing that they are at a disadvantage, Asta nullifies the curse power that has been deteriorating his wounds and challenges his opponents in a fight as he tries to overcome the adversity.

The fight begins with the five mages launch a simultaneous attacks towards Asta, who manages to deflect them all. However, the mages easily neutralize the deflected attacks. The young Knight then continues his ferocious assaults on his opponents alongside Leopold. In the middle of the fight, Noelle tries to protect them with a barrier spell, but one of the mages is able to easily neutralize it. As they try to take advantage of the situation, Asta and Leopold charge towards one of the mages as Noelle's barrier is disappearing. However, their attempt to attack fail as the said mage launches several attacks, which cause critical damages on the both of them.

The said attacks render Asta unconscious as he remains on the ground. The mages then try to kill both Asta and Leopold but the remaining Knights whom were sent away by Valtos, return and intercept the attack. The mages who identified themselves as members of the Eye of the Midnight Sun, escape while also taking Asta along with them.

When Asta regains his consciousness, they have already arrive at the Eye of the Midnight Sun's hideout. The young Knight remains helpless as he is trapped within Sally's magic spell, a mage who is eager to dissect him and his grimoire. When they finally enter the hideout, Julius reveals himself and swiftly defeats three of the mages while restraining the rest of the Eye of the Midnight Sun's mages. Asta finally breaks free of Sally's spell after the said mage is restrained. He then can only sit in amazement and fear after seeing the feats, which were done by the man he needs to surpass in order to become the Magic Emperor.

After seeing Julius' power firsthand, Asta's feet become numb as he forces himself to stand up after the Magic Emperor lent his hand. Not long after, while Julius questions the Eye of the Midnight Sun members about a sephirot in their hideout, a bright light manifest and prevents Asta from seeing the culprit. When it recedes, Asta realizes that the rogue mages have gone, but Julius is able to secure one of them. Asta is then taken back to the Royal Capital by Julius after receiving an update from Marx Francois, one of his aides.

Once they arrive, Asta is greeted by Noelle, Klaus, Mimosa, and Nero, who are very relieved when they see the young Knight. Asta then remains with his fellow Knights as Julius addresses them in regards to the conflict with the Eye of the Midnight Sun. When Nozel decides to leave as soon as the Emperor is done, Asta expresses his confusion over the Silver Eagle captain's lack of camaraderie. Not long after, Leopold comes out of the medical ward and vows to become the next Magic Emperor in which Asta accepts him as one of his rivals. He then asks Leopold to properly introduces himself to him.

Not long after, Asta, Charmy, and Noelle prepare to leave the Royal Capital, but they end up lost within the city. As they stroll around while having a conversation, they encounter Yuno, Klaus and Mimosa. The moment Asta strikes a conversation with Yuno, the latter immediately launches an attack towards the Black Bull members. Asta manages to nullify it and finds out that Yuno uses the spell to say his farewell towards his foster brother.

Afterwards, at the Black Bull's headquarters, Asta greets Magna and Luck, who have just returned from their mission. The young Knight then tells his senior that he has been promoted to a 3rd class Junior Magic Knight. However, both of them fail to comprehend Asta's attempt to boast himself, until Yami explains the significance of it. Asta then relays his worries over Fuegoleon to his captain, but Yami managed to cheer him up before he tells him to rest. Suddenly, Finral arrives through his Spatial Magic spell and invites Asta to a blind date.

Later that day, at a restaurant in Nairn, Asta attends a blind date with Finral and Luck. As his seniors finish their introductions, the young Black Bull mage also introduces himself. Unfortunately, his speech is not received well by the ladies, so he shows off the wounds that he received during the Royal Capital's invasion, which further reduces their interest in him. As Luck and Finral are finally able to have a lively conversation with their dates, Asta also tries to break the ice with his date, Rebecca Scarlet. She reveals her intention and disinterest as she prefers to stay with her siblings. In response, Asta begins to tell her about his own foster siblings, which quickly grabs her interest and they are able to have a topic of interest.

Suddenly, a drunk burly man interrupts them and begins to insult Rebecca by mocking her living situation. Asta immediately puts drunkard in his place by throwing him across the hall. His action prompts Rebecca to take him away from the restaurant into an alley. She then asks Asta whether he has someone of romantic interest. The Black Bull Knight confirms it, but he refrains from revealing her identity as his thoughts are filled with the image of Sister Lily. Subsequently, Rebecca invites Asta to play with her siblings sometime, which he is in agreement. He then asks Rebecca the true purpose of a blind date, which quickly stuns her.

The next day, Asta returns to Nairn to play with Rebecca's siblings. He meets with a little girl named Marie Adlai who ends up playing with them. When Asta tries to take her for a spin, Marie's older brother, Gauche Adlai, immediately interferes and kicks him down. As the Black Bull mage quickly identifies Marie's older brother as his senior in the squad, the latter beats him further when Marie reveals her intention to marry Asta. A while later, after Marie returned to the church, Asta and Gauche decide to spend the night at Rebecca's house. The young Knight quickly praises Rebecca's cooking skill after he tasted her dishes.

When the night falls and Asta is fast asleep, he is suddenly attacked by Gauche who is determined to kill him for bonding with Marie. The Black Bull Knight tries to reason with his senior, but he fails and the latter manages to push him out of the house. The moment Asta realizes that the town has been covered in snow, Rebecca comes towards him and informs the disappearance of her siblings. Afterward, the other citizens of Nairn begin to wake up and discover that their children are gone.

While Asta still tries to evade Gauche's assaults, Noelle comes along and informs them that she saw a group of children walking towards the mountain area. At that moment, the Sisters of the church arrive and reveal that the children of the church have gone missing as well. The fact that Marie has also been kidnapped quickly infuriates Gauche as he tries to vent his anger towards Sister Theresa. Fortunately, Asta manages to stop him and asks him to calm down by hitting him. As the young Knight urges his senior to use the time to look for hints of the children's whereabouts, it reminds Gauche of the mirror, which he gave to Marie, that he could use to trace them. Asta, Gauche, and Theresa then leave Nairn to pursue the children after the young Knight assures Rebecca of her siblings' safety.

As they near the caves, Asta spots Marco Scarlet laying outside and asks Gauche to get closer. Gauche refuses and tells Asta to let go, which he does. Theresa joins Asta next to Marco, and Asta taps the boy on the head with the Demon-Slayer Sword, freeing the boy from the enchantment. After being healed, Marco does not want to be left alone, so Asta lends him the Black Bull squad robe as comfort. When Asta and Theresa arrive in the cave, she notes that the children's mana has been drained and may never be able to use magic, which infuriates Asta. As Baro mocks him for not having mana, Asta hits him with the Demon-Slayer Sword. Asta threatens Baro and punches the wall next to his head, saying that beating Baro up will not undo the damage to the children. Asta then frees the children from the enchantment. As she heals the children, Theresa mentions to Asta that she knows Sister Lily, who described the boy as short and loud but is proud of his hard work ethic, much to Asta's delight.

Asta demands to know how to return the children's mana. Suddenly Sally appears from a portal and is delighted to see Asta. Asta warns the others about her. After Gauche's spells prove ineffective against her Gel Magic, Sally grabs Asta and pulls him onto her salamander, where she tastes his blood. As Sally tries to remove his pinky fingernail, Theresa frees the boy with Fire Magic. Asta is surprised to learn that Theresa was a Magic Knight and knows Fuegoleon, and asks if she has heard what happened to him, which she confirms. When Sally turns Baro into a giant mud monster, Asta and Theresa move to defend the children, while Gauche grabs Marie and flies away. While fighting the monster, Asta saves Neige from being smashed because he still has to pay for what he has done. Asta tries cutting the monster to pieces, but Sally reveals that its overwhelming magic is fueled by Baro's lifeforce. Theresa then saves Asta again from Sally's attempt to capture him.

When Gauche returns, he finds Asta and Theresa exhausted, but Asta still refuses to give up. Asta declares that he will die before letting the children be harmed and rushes in but has to be saved by Gauche. When Gauche's spells prove ineffective, Asta saves his squadmate and tells him that they need to work together as a team. Gauche agrees, which causes the Demon-Dweller Sword to appear and fills it with Gauche's magic. Asta swings the sword and releases a flying slash of Anti Magic light. Gauche then has Asta look into his mirror eye and multiplies the boy. The multiples Astas all swings their swords and destroy the monster with Mirrors Slash.

After the clones dissipate, Asta is attacked by Baro, but Neige freezes his brother. Neige asks if they can be friends after he serves time in prison, and Asta agrees and thanks Neige for saving him. Suddenly Neige and Gauche are struck down by blades of light. Asta carries Neige over to the others behind Theresa, who raises a defense. However, she is struck down, too. Asta then notices that Sally has disappeared and recognizes Licht, who formally introduces himself. Asta is then shocked to see that Licht has a four-leaf clover grimoire, like Yuno. Confused by Licht's speech about victims, Asta points out that the Eye of the Midnight Sun attacked first. Rebuking the statement, Licht pierces Asta's leg and asks about the boy's grimoire. Asta tries to hide behind his larger sword, but Licht appears behind him and attacks. To Asta's surprise, Yami drops out of a portal and blocks the attack.

Asta asks Finral to carry the injured back to Nairn and stays behind to keep fighting. Asta is impressed by Yami's ability to block Licht's attacks. Asta listens but gets confused as Licht and Yami relate their backstories. The boy is shocked when Licht admits to injuring Fuegoleon. After Yami injures Licht, the captain tells Asta to do the same, much to the boy's disbelief. Yami then instructs Asta in how to use ki and orders him to take out Valtos. Asta listens for Valtos' attack but is still hit, and Yami kicks him for using just his ears. Asta concentrates and manages to reflect Valtos' attack back, hitting him in the chest. Angered, Licht lashes out and causes a cave-in, but Asta and Yami use ki to dodge the rocks.

Yami orders Asta to take on Licht but, changing his mind, orders the boy to finish fighting Valtos. Asta is distracted by Yami and Licht's fight, and Valtos tries to interfere. Yami then threatens Asta again for not dealing with Valtos. Asta charges forward and Valtos attacks from multiple angles at once. Asta reflects some of them back but Valtos escapes before they hit. As the assault continues, Asta's numerous injuries are taking their toll. In a desperate attempt, Asta tosses his swords aside, tempting Valtos to fire a larger attack. Asta then jumps through the portal and punches Valtos.

Asta marvels at Yami's massive injury to Licht. When Licht decides to unleash his most powerful spell, Asta believes Yami can handle it, but the captain reveals that it is too much for him. Asta panics while Yami tries to construct a defense. Gauche saves them by reflecting the spell with a giant mirror.

Before the fifth match, Asta questions who would be named "Cross", but Mimosa explains it is "X" and probably for anonymity. Asta is creeped out and surprised when a weird Magic Knight starts laughing and reveals himself to be Rill. His butler, Walter, also appears, to Asta's shock, and when Asta and Rill greet each other, Walter offers the boy some tea. As he sips the tea, Asta realizes that the taste is too high-class for him. Walter then thanks him for being a friend to Rill. During the match, Asta is amazed when Rill counters two enhanced spells at the same time. Afterwards Walter celebrates Rill lack of focus forcing his teammates to work harder, and Asta questions such a talent.

During the sixth match, Asta notices that Luck's boots have changed, and Magna explains that the spell has evolved since Luck has added pages to his grimoire. Asta cheers when Klaus drills through his opponent's spell, and is amazed when Puli Angel flies. After Luck kicks Rob Vitesse into the crystal, destroying it and winning the match, Asta and Magna worry about how strong Luck is.

Asta is then pumped to watch Noelle and Yuno in the eighth match, and when the two start bickering, Asta tries to calm down Noelle but is interrupted by Solid. During the match, Asta cheers for Noelle when she splits up with Yuno and heads for Team O's crystal by herself, and when she defeats her brother and destroys the crystal with one spell.

Afterwards, Asta congratulates Yuno and Noelle as they return to the platform. Julius then calls for the battlefield to be rearranged for the second round, and Asta notices Zora twitch at this. Before the next match, Asta asks Zora if he was bothered by his traps getting moved, and after the rogue reveals he placed them the night before, Asta demands to know where they are located. Zora refuses to tell so Asta decides to deal with them himself.

At the start of the match, Kirsch covers the battlefield with Magic Cherry Blossom Blizzard, so Asta unleashes Black Hurricane, which nullifies all of the cherry blossoms and traps, aggravating both Kirsch and Zora. Asta declares to Zora that he wants to fight as a team, once the group formulate a plan, they split up with Mimosa heading towards Team C's crystal. Kirsch manages to locate Asta and attacks him with his Dance of 100 Million Cherry Blossoms which Asta deflects while retreating soon after. He runs towards an opening within a nearby cliff where he taunts Kirsch into following him, Kirsch senses the traps set up by Zora and utilizes his cherry blossom clones in order to set them off. As Kirsch rushes towards Asta to finish him, he falls into a pit set up by Team B where Asta jumps into the pit to flatten and knock out Kirsch. Zora starts to set a trap on top of the hole until Asta hears a familiar sound behind them. He turns to see Magna racing towards them.

Magna says he will not get close to give Asta the advantage of fighting as their distance guarantees him a win. He throws a fireball which Asta notes he can hit easily. Asta is shocked when the fireball disappears and hits the crystal. Magna explains that it is due to his new spell Extreme Killing Vanishing Fireball. At that moment, Zora tells Asta to stall for five minutes as he prepares a trap.Asta continues to try to hit Magna's fireballs to no avail. After some time, he manages to hit one which shocks Magna. He tells him to keep throwing fireballs which excites them both. As they continue fighting, Kirsch surprises Asta with his quick recovery. Zora finishes his trap and tells Asta to go fight Kirsch. Angry from Asta knocking him out earlier, Kirsch declares he will defeat him by using his full power. However, before he could attack, one of Zora's traps activates. This allows Asta to knock him unconscious once again. Sol appears preparing to destroy Team B's crystal. Before she can destroy it, Mimosa's spell activates and takes control of the golem. Asta takes the opportunity to destroy the other team's crystal; therefore, winning the match. Afterwards, Zora calls out the improvements Team C needs in an insulting way. Asta tells him he is being a jerk.

They clear the battefield and watch Finral's match against Langris. When Langris prepares to launch an attack against Finral, Asta senses that he has felt this feeling before. He and the other participants are amazed by the fight. Asta calls out to Finral as he lies on the ground unconscious. Despite the match being over, Langris prepares a spell to kill Finral. At that moment, Asta, Luck, and Magna surround Langris. Asta tells him the match is over and there is something wrong with him. He tells him how Finral said Langris was actually kind, but Asta says Finral is nicer than anyone and is a true Magic Knight. He says Langris is not a Magic Knight which angers Langris. Langris asks the Magic Emperor if he could fight Asta before the next match. Instead of waiting for an answer, he proceeds to launch an attack at Asta. However, Asta quickly destroys it with his Demon-Slayer Sword.

The Magic Emperor uses his Time Magic to stop the two Magic Knights from fighting further. He tells them he will allow the fight as long as they follow the exam rules. When Asta is released, he apologizes to Mimosa and Zora for moving up their fight. He explains how he wants to beat Langris and they agree to help. Asta is defending their crystal from Langris's spells, but he ends up getting hit in the leg. Mimosa heals him and he continues the fight. He thinks about his time with Finral and declares he will win. As he deflects Langris's spells, he orders Zora to attack. Langris's spells avoid the first trap, but Zora reveals the trap placed on his body. The trap reflects the Spatial Magic back towards Langris, but to no avail. Just as Langris launches another attack at Zora, Asta reveals his black form and easily negates the magic. Langris asks what is that form, but Asta tells him it is nothing special. He explains how he idolized people like Langris and wanted to protect people along with them. This infuriates Langris even further and he prepares to attack him. Asta uses Black Meteorite to launch himself at Langris and Team G's crystal, destroying it. However, Team B's crystal breaks at the same time which makes their match a draw. Asta passes out from exhaustion and taken into recovery.While he is recovering, he is distraught over not fighting Yuno in the final round.

A few days later, he is at the hideout in a daze. His teammates try to cheer him up with no success. Suddenly, Mereoleona bursts into the hideout and punches him in the face. After giving Yami alcohol as a thank you, she grabs Asta, Noelle, and Luck as they passed the exam. At the gathering of the Royal Knights, Asta is shocked to find out Zora's identity and position in the Black Bulls. They are all chatting until Mereoleona interrupts to tell them to go change into their Royal Knight Robes. After they change into their new robes, they are informed that Nozel, Cob, and Siren are also a part of the squad. Mereoleona explains where the Eye of the Midnight Sun base is located and they depart.

Outside of the Gravito Stones, Asta is placed on a team with Mereoleona and Zora. She tells everybody that the plan is to fight anyway they like and head to the center of the palace. They head inside to start their attack. After Mereoleona single-handedly defeated three Eye of the Midnight Sun members, they notice there are two Astas. Mereoleona uses her flame magic to burn them both, which reveals the clone is Rhya. Asta and Zora stand by and watch as Mereoleona fights with Rhya. Asta is amazed by the fight happening right before his eyes.

When Rhya is about to use his self destruct spell, Asta quickly uses the Demon-Slayer sword to stop him. He punches Rhya and tells him not to treat his life like garbage. He demands for Rhya to tell his side of story, but Mereoleona tells him that those people are not interested in a mutual understanding. He asks why as they are the same as the elves. He goes on about wanting to build a country where everybody is equal. This touches Rhya, but he deems it a little too late. As the elves reincarnation begin, Asta is confused on why Rhya is glowing. Rhya gets up and attacks with Light and Dark Magic, which Asta is surprised that he is using two different types of magic at the same time. Mereoleona counters by using a spell to destroy both spells. Mereoleona tells Asta that even through he wants them to understand each other, there is no path that will reach that goal. Mereoleona also comments about how the enemies feelings are set in stone, and that they only want to kill them. Asta replies that he will win, and create a path where they can understand one another. As they are fighting Rhya, an elf-possessed Rill bursts into the room with Four-Headed Lindworm.

Asta asks why Rill is being friendly with Rhya, but the elf introduces himself as Lira. Still confused, Asta tries to explain how they are friends, but Lira claims he has no human friends. He proceeds to attack them with Four-Headed Lindworm. Zora tells Asta that Rill is possessed, so he need to use his Anti Magic to stop them. Rhya says it will not reach them just as Zora activates his trap. This allows Asta to lounge at them with his sword, hitting Lira in he process. He is shocked when Rill does not turn back. Rhya explains how it is a result of the reincarnation spell. At that moment, three other elves show up. Zora tells Asta to fall back as they need to come up with a plan. The five elves proceed to attack them, but Mereoleona blocks it. She pushes them both out as she plans to take on all five by herself. Asta tells Zora they have to go back for her, but he says they will just end up being killed. Zora explains how Mereoleona sealed herself in for a reason and to not let it be in vain. Asta disagrees and says he has a plan. He asks Zora if he could use his trap to bounce back all of their magic. However, Zora doubts that all five elves will attack at the same time.

Just as the five elves combine their magic to kill Mereoleona, Asta and Zora arrive back in time to block it. Using Zora's spell, he absorbs the elves' magic and bounces it to Asta. Asta uses his sword to bounce it back to Zora. They do this again until Zora's circle begins to break. Asta gets behind the circle and hits the spell towards the elves. As that happens, they grab Mereoleona and escape. As they are escaping, Rhya grabs Asta's leg intending to stop him. Asta hands Mereoleona to Zora and proclaims he will make it back alive. He is taken to Licht's chamber where he tries to free Mimosa. He notices Yuno is possessed and tries to talk to him but gets attacked by the elf inhabiting Klaus. As he is being attacked, he proclaims that he will not die and will become the Magic Emperor. Those words causes Yuno to come back to his senses and come to Asta's defense.

Asta asks Yuno if it really him and Yuno replies that it is, which makes Asta happy. Yuno tells Asta to rest as he will fight the elves in front of them. Asta laughs and says he will fight along with him. Using Black Asta and Spirit Dive, they both defeat the two elves. Seeing the elves defeated gathers Licht's attention. Asta quickly notices how he is the leader of the Eye of the Midgnight Sun. At that moment, Nero pops out of his shirt and pecks him, which confuses Asta.

After placing the defeated elves on the ground, Licht pulls a sword from the floor, and walks towards Asta and Yuno, with the two of them preparing to fight back. As Asta draws his Demon-Dweller Sword, Licht closes the distance between them in an instant, catching them both off guard. He then takes the sword from Asta and uses it to repel the boys crashing into a wall. Asta is heavily injured by the attack and loses his black form in the process. He thinks how powerful Licht is and that his body is unable to move anymore. Still being able to fight, Yuno proceeds to fight back against Licht alone, with the elf on the verge of victory. However, before Licht can release his attack, Asta regains the use of his black form and charges into the air, surprising the elf and striking him together alongside Yuno.

However, Licht deflects their attack with his second sword, which is knocked out of his hand and then grabbed by Asta. Licht then releases a magical blast from the Demon-Dweller Sword, which sends Asta and Yuno crashing out from the air all the way through to the bottom of the dungeon and down to the ground below, with Yuno using his magic to protect them, and Mimosa as they are all sent crashing into the water below them.

After surviving Licht's attack, Asta, Yuno and Mimosa are meet by the other surviving members of the royal knights and later regroups with them outside of the dungeon. While being healed by the magic item given to them by Nozel, Asta and the others are informed about the elves attacking the kingdom, with Nozel stating that the kingdom needs to be saved even if it means killing the possessed Magic Knights. After Noelle suggests saving them instead of killing them, Asta and others agree, with Nozel accepting the decision and creating a vessel for everyone to travel back to the kingdom.

As they pass over the Forsaken Realm, Asta and Yuno notice that many villages in the area are being attacked by elves, including Hage. Despite asking to stop to defend Hage, Nozel refuses stating that the capital takes priority, however he does allow Asta and Yuno to go alone, telling them to catch up with them later in the capital. After departing, Asta and Yuno manage to arrive in time to stop the elf from killing Nash, Sister Lily, and the rest of their foster family. After complimenting Nash for his bravery, the two step up to fight against the elf, holding back many of the elf's attacks. After hearing that Father Orsi was poisoned, Asta leaves the elf to Yuno and goes to the father's side to help. Asta tries to dispel the poison with his Demon-Slayer Sword, but is unable to remove the poison. After failing with Demon-Slayer Sword, Asta notices the sword he grabbed from Licht appearing from his grimoire and tries using that, which ends up removing the poison from the Father's body. As the Anti Magic flows out from the sword and absorbs the poison in all the citizens, Asta gets an idea and returns to Yuno's side to fight the elf. After having a path opened for him by Yuno, Asta jabs the elf with his new sword, which dispelled the Reincarnation Magic and exorcises the elf spirit. After realizing that the sword could be used to save everyone possessed by the elves, Asta happily shows it off to Yuno, who then states that he was the one that did most of the work in defeating the elf. After being thanked by everyone in the village, Asta and Yuno leave with the formally possessed Magic Knight, now heading straight for the capital to help save the kingdom.

After travelling for a while, Yuno tells the others that they are going to reach the common realm soon. Yuno also says that he can sense elf magic coming from two directions, which leads to Asta suggesting that they split up. Asta also suggests that Yuno take the Purple Orca member since he has his sword. Yuno agrees with Asta, while also commenting that they can use the Poison Plant Magic to stop the elf from moving. Both Asta and Yuno then agree to meet up at the capital. As Asta makes his way towards the town he notices a bolt of lightning in the sky. After reaching the town that was being attacked by the elf, Asta shows up in time to see that the Magic Knight who was attacking the town was Luck, who was being possessed by the spirit of Lufulu, and that the ones fighting him off were Magna and Vanessa. As Lufulu prepares to kill Magna, Asta shows up and saves Magna. Vanessa figured that Rouge used the last of its power to bring Asta there. Asta prepares to fight Lufulu, while also proclaiming that they are Luck's friends. Lufulu tells Asta that they are starting to anger him, and also comments about how someone like Asta, who has no mana, actually existing and that someone like him fight against him to be amusing. Asta replies that the Black Bulls already acknowledged him and that he will not let any of them be lost. As Asta joins the battle, Lufulu is shocked by Asta's ability to follow and counter his movements, and begins to change tactics. As Asta begins losing ground in the battle he asks Magna and Vanessa for help to deal with Lufulu's attacks. Knowing that his body will not hold out for much longer, Asta prepares to finish him off for his next attack. As Asta charges at Lufulu, Magna creates a smokescreen to block Lufulu's sight. Lufulu counters by expanding his mana, and finding out where is mana is being dispelled. As Lufulu finds out where Asta is, he prepares to finish Asta off. Vanessa uses her thread to pull back Asta, while Magna uses a fireball to cut Vanessa's thread. Lufulu figures out that they used the thread in order to adjust the timing of Asta attack. Asta then lands a hit on Lufulu.

Asta mounts Lufulu and goes to stab him with his sword, but Lufulu releases his mana to block Asta. As Lufulu goes to kill Asta, Magna and Vanessa quickly grab and hold Lufulu down. Lufulu decides to release all of his mana in order to kill the three, which they notices that Lufulu will become something else entirely. As Lufulu proclaim that he will never forgive the human for taking what is precious to him, Asta replies to Lufulu that he does not know what happened to Lufulu but still apologizes. Asta also says that Luck is their precious comrade and to please not take him away from them. Luck hears Asta's words and rushes to wakes himself up. As the spell is being undone, Lufulu remember what Licht's friend once said and comments about how he wish to have gotten to know them. As Luck wakes up, he comments about how he is the Black Bulls comrade while having tears run down his face. Asta watches as Magna hugs Luck and replies that they are his comrades. After breaking the spell on Luck, the group decide to stop at their base on their way to the capital, finding the base in ruins. After finding Gordon, Grey, and Henry at the base, Asta had to be the one to help them explain what happened to the base, as well as be the one to introduce Henry to the others. After finding out that Gauche was also possessed by an elf, Charmy also returns, upset about her ruined meal. After Charmy feeds everyone with food that restores their magic power, Henry reconstructs the base, and they all head off to Hecairo, where Luck senses three more elves in town.

After the black Bulls work together to fight the elves, Asta and the others begin to celebrate their victory till they are interrupted by the arrival of Rades, Sally, and Valtos. Rades offers to transport them to the capital in exchange for help with killing their former leader. Asta immediately refuses to work with Rades for revenge and wants him to atone instead. After relentless arguing with one another, Asta finally managed to convince Rades, as well as Sally and Valots to help them save the country, with all three accepting Charmy's food, and Valtos transporting the base right into the capital. After the Apostles of Sephirah arrive to summon the Shadow Palace, the base is warped into Clover Castle's courtyard and everyone then begins to fight off several elves in the area. When the group of elves are defeated, the Coral Peacocks's captain, Dorothy Unsworth arrives, possessed by the elf Reve who pulls part of the base into her Glamour World. Meanwhile, Patolli, alongside Gauche, who is possessed by the elf Drowa, combine their magic to destroy the rest of the base, with Gordon and Grey cushioning everyone's fall. After Rades and Valos decide to leave, Drowa tells Patolli to head to the Shadow Palace while he deals with the humans, with Henry telling the others to get away from him. Just then, Noelle and Zora arrive, much to everyones surprise, and after which Yami and Jack also arrive, seeing Patolli headed for the Shadow Palace and deciding to follow him there. Before he leaves, Yami tells them that they can handle things from here, and tells them to surpass their limits, to which everyone agrees.

After Yami's departure, the black bulls proceed to battle Drowa. With help from his sister Eclat, Drowa creates multiple mirrors and uses them to reflect his sister's magic, paralyzing everyone. Asta then states how strong Marie is even without her Grimorie. With Drowa declaring that he's going to kill everyone without any of them having the ability to stop him, Asta them manages to use his new sword to free himself, along with Henry, Grey and Gordon. After noticing that Asta's wielding the Demon-Destroyer Sword, Drowa becomes angry and attacks Asta, stating that the sword does not belong to him. With Grey and Gordon as backup, Asta manages to slowly turn the tide back in their favor. Asta then goes into detail about knowing all of Gauche's spells, and that he knows him well enough to deal with them, even if he is possessed. Asta, Gordon, Henry, and Grey then begin to explain what kind of person Gauche is, and that they will get him back. However, Drowa says that he still has some spells left and tells Eclat that they will use that. Drowa then sends his mirror to the four, which Asta says that they can easily deal with that. Suddenly Asta is sent flying towards Drowa and Eclat. Drowa thinks about what the Demon-Destroyer Sword is capable of, and reflects Eclat's image on the mirrors surrounding Asta. Asta closes his eyes to avoid looking at Eclat, which Drowa fires a spell at Asta. Asta manages to counter the spell by using his instincts. After that Drowa fires multiple attacks at Asta, which are blocked thanks to help from Grey, Gordon, and Henry.As Drowa's spell manages to destroy the shield, Asta enters his black form and destroys the spell. Asta then destroys Drowa's mirrors while heading towards Drowa, but suddenly sees Eclat's image from the mirror in Drowa's eye. As Asta is paralyzed, Drowa fires a powerful spell to kill Asta. Grey, Gordon, and Henry use their magic not only to reach Asta, but also to block the spell that Drowa fired. Henry thinks about how powerful Drowa is, but all of they will still save Gauche.

Drowa figures out how Asta's tactic works and creates a giant mirror ball that scatters light in a wide are, forcing Asta to chase after them and waste his time in his black form. Drowa creates a large mirror to reflect Eclat's eyes. Henry has everyone gather within his mobile base, which Asta thinks about how he can only use his black form one more time but it will not last as long. Grey uses her magic to transform the mobile base into a mirror one, and flies towards Drowa and Eclat. Drowa uses mirrors to redirect the four upwards, and uses a spell to destroy the base's engine. Henry then ejects Asta, Grey, and Gordon, and falls towards Drowa and Eclat. As Drowa comments about what Henry is planning to do, which Henry destroys the base and begins to absorb Drowa and Eclat's mana. Drowa is shocked by this but says that its useless while he prepares to attack Henry. As Henry tells the other that its in their hands now, but Asta says that Henry is not dying yet. Henry remembers when he met Asta and what they talked about, and thinks about how he wants to continue living with his friends. Gordon uses his magic to cover the mirror ball, while Asta throws his sword at Henry. The sword is actually Grey who undoes her transformation and uses her magic to create a soft landing for Henry and herself. Asta then attacks Drowa and Eclat with his Demon-Destroyer Sword. After knocking them to the ground, Asta prepares to free Gauche and Marie, but Drowa at the last minute tells all of them about the humans who attacked his people and how they were nothing like them. After being asked to undo the spell, Asta uses his sword to exorcise Drowa and Eclat, with Drowa expressing his gratitude and saying that he will never forget them. After Asta exorcises the spirits, Gauche chastises Asta, Gordon, Grey, and Henry for risking themselves for him and Marie, but dropping his aloof nature, he thanks them. They hug him as the rest of the Black Bulls, along with Sally and Reve drop down from above, with Noelle and Zora joining in. After exorcising Reve, Asta happily states that the Black Bulls, minus Finral, were together again. As the group prepares to follow Yami into the Shadow Palace, they are attacked by two elves, but Fuegoleon and Mereoleona arrive and defeat the elves. As the gate to the Shadow Palace is shrinking, more possessed Golden Dawns attack, so the Black Bulls and Kirsch remain to hold them off while the captains, Asta, Noelle, and Mimosa fly to the gate, with Yuno and Charmy briefly following them into the gate right before it closes.

As the Magic knights pass through the gate, the travel through a strange space that disrupts mana, with Nozel stating the this space was the border between the living and the afterlife, which causes Asta to panic. After entering the Shadow Palace, the group are separated from one another immediately, with everyone being sent to a different area of the Palace. Asta slams into a floor face first and Mimosa lands on him, smashing his head into the stone. Mimosa quickly apologizes and uses her magic to heal him. As Mimosa is healing Asta, they notice that the others are not with them and wonder where they all are. Once Asta is healed, he notices that he can use his black form again and thanks Mimosa. She then maps the layout of the Shadow Palace, which impresses Asta. Mimosa identifies that the large rooms each have an elf in them and that she and Asta are in a corridor that connects two rooms. She then says that everyone else was scattered and that they will have to defeat the elves in order to meet up with everyone else. She also notices that Licht is in the topmost room. Asta says that they will just have to defeat all the enemies and rendezvous at the top were the boss is.

Asta and Mimosa then head up into the room above them. The room is full of painted canvases floating around. Greeting them, Lira informs them that he will be using them to practice his Painting Magic, until the final magic stone is put in place. Asta promises to wake up Rill, but Lira insists that he is Lira and is already awake. As Lira summons his creations from the paintings, he remarks that Painting Magic is much better than his original Scribble Magic. He declares that they will repaint the world after all the humans are erased. Asta gets ready for battle and says that this is not going to be easy after all. The pair are slowly overwhelmed by the number of monsters created by Lira, so Asta carries Mimosa on his back while she heals their injuries. During the battle, Charmy appears, weaving through the attacks and blocking them with her magic, with Asta questioning Charmy about how she even got there. After this, Asta tells Charmy that Lira the one creating the monsters, prompting her to fly up to him and offer him food to ease his frustrations. After having her food swat away crashing to the floor, Charmy became angry and attacked Lira with her sheep, but was still sent crashing to ground by his monsters. After this, Asta and Mimosa both watch in shock as Charmy stands back up, this time taller, with her sheep now turned into a wolf. After seeing this and sensing her mana, Lira thinks about how he has felt this mana a long time ago, and announces that Charmy is a hybrid of a human and a dwarf, shocking everyone, including Charmy who was surprised by this and the fact that her wolf was talking. When Lira resumes his attacks, Charmy unleashes her new magic, as her wolf begins consuming everything that lira paints, and Asta comments on how he thought that she was only a cotton magic user. As the fight continues, Charmy tells Asta and Mimosa to move on ahead while she handles Lira, with the two now headed to the next room.

As Asta and Mimosa reach the next room, Mimosa notices an unconscious David. Asta asks who David is, which Mimosa informs Asta that David is a senior member of the Golden Dawn that had been possessed by the enemy. As Asta wonders who knocked him out, and takes the opportunity to undo the reincarnation spell, while Mimosa senses the faint remnants of mana in the room that does not belong to a human or an elf. As Mimosa wonders what kind of mana that was, she decides to create a replica of the Shadow Palace with her spell. Mimosa finds out that Yuno is in another room with three elves and a pedestal. Asta says that they should head there, and thinks that Yuno should wait for them. As Asta and Mimosa finally arrive in the room, Mimosa notices the situation that is happening and wonders about the devil. Asta also notices that devil and wonders what it is, but thinks about how he may already knows the answer to that question. The devil comments about how some uninvited quests have arrive, but decides to deal with them later. The devil decides to deal with Patolli first and uses his magic to bring Patolli to him. Patolli figures out how the devil's magic works and how the devil used that magic to mimic Ronne's magic. Patolli get angry and tries to attack the devil, but the devil easily destroys the spell. The devil then pins Patolli in mid-air by spearing him with spears. Yuno sees this and tells Asta that the devil is the mastermind behind all of this. Asta agrees with Yuno and both charge towards the devil. The devil defends himself by having the raining blade appear, which Asta and Yuno try to defend against. Asta notices that there are real blades mixed in and tries to dodge them since his Anti Magic will not work on them. However the two are easily sent crashing into the floor, and then crushed even further into the ground due to his magic, with the devil mocking Patolli and explaining how easy it was to revive and fool him and the rest of the elves. Both Asta and Yuno get back up and express how their dreams would never lose to a piece of trash like the him, with both of them making short work his blade attacks together and strike him as well. As Asta and Yuno manage to crack the devil's arm, he uses his Kotodama Magic to heal his wound. Zagred is impressed that they were able to wound him, and comments on Yuno's power form an elf and a spirit and Asta's power from a devil. Zagred does not recognize Asta's devil and is not concerned with taking back Licht's grimoire. Rades Spirito and Valtos are hiding inside a corridor into the chamber, with Rades wondering what the black creature is and if it used Patolli how the elf used the humans in the Eye of the Midnight Sun.

Zagred turns his attention back to Patolli and explains how a five-leaf clover is born, while Patolli's four-leaf clover turns to a five-leaf. With the five-leaf grimoire now complete, Zagred plans to enter the real world and unleash his true form and power. He explains that after his failed attempt 500 years ago, he used the corrupting effect of forbidden Reincarnation Magic to make the process easier. As Zagred takes the grimoire, Asta and Yuno rush forward to stop him, but he says that he is not their opponent and tells Patolli to go on a rampage, freeing the elf from the iron spears. The elf, who has given into his hatred and despair, has turned into a dark elf. Patolli uses Demon Light Magic to attack Yuno and Asta. Yuno is cut when he tries to dodge, as the black light is faster. Asta is pushed back into a wall and survives due to his overflowing Anti Magic weakening the attack's power.

Zagred decides to exit through the corridor in the ceiling. Asta tells the devil not to leave, but Patolli suddenly attacks, forcing Asta to deflect the strike. Yuno uses this chance to attack with Spirit Storm, but Patolli dodges the spell, throws swords at Yuno, and loops back to attack Asta again. While blocking the thrust, Asta tells Patolli that they might not forgive each other, but they are still able to understand each other. Asta also tells Patolli to get out of their way and pushes Patolli back with his sword. Patolli gets angry and starts to charging an attack, which Asta recognizes. Asta and Yuno both manage to stop the attack, however Patolli begins to charge up for another attack. Before he is able to finish however, Nozel appears and blocks the attack with his magic. Nozel then tells Patolli that he cannot win again him since his Mercury Magic has a better affinity against Patolli's Light Magic. As Patolli launches another spell at Nozel, Nozel counters by creating shields that reflect the light. Nozel then start to launch mercury at Patolli but Patolli uses his magic to dodge it all. Nozel compliments Patolli on his ability, but that his preparation is now complete. Nozel cast a spell that traps Patolli and will continue to attack him. As Patolli continues to dodge the prison's attacks, he decides to attack Nozel. As Patolli launches spells at Nozel, the prison reflects the spells back at him. As Patolli is defeated, Nozel tells Asta and Yuno that he will be the one to become the Magic Emperor. Nozel then plans to finish Patolli off, but Asta and Yuno convince Nozel to let Asta use his sword on Patolli since Patolli is using Vangeance's body. As Asta uses his sword on Patolli, Asta consciousness is pulled into Patolli's mind and he sees all of Patolli's memories. Asta then confronts Patolli and convinces him to continue to fight and not give up. After Asta and Patolli wake up, both agree to work together to stop Zagred. When a demonic creature pours down from the chamber above, Patolli recognizes that it is from the devil's world. It absorbs his attacks and a piece of it falls on his arm, burning him and draining some of his mana and lifeforce, so he is surprised when Asta emerges from a pile unscathed. Nozel assigns Patolli, Asta, and Yuno to go after Zagred, while he and Mimosa evacuate everyone else.

Asta, Yuno, and Patolli arrive at the top floor to see that Licht is already fight against Zagred, which Zagred noticing their arrival and commenting about how Patolli's transformation has come undone while also thinking that Asta's Anti Magic will be troublesome. Suddenly Lemiel Silvamillion Clover and Secre Swallowtail burst into the room, which Zagred says that he is surprised to see Lemiel again. Yuno informs Asta who Lemiel is, while Secre informs Lemiel who Asta and Yuno are. Lemiel and Secre notices Licht and head over to examine him. After examining him, Secre uses her magic to unseal Licht's soul. Once Licht's soul is unsealed, Licht thanks Lemiel for what he had done back then. Lemiel, Licht, and Secre head over to where Asta, Yuno, and Patolli are at. Licht talks with Patolli about what Patolli had done, and hugs Patolli while commenting about how even through Patolli made mistakes, he did help out their people.

Licht and Lemiel then turn to Zagred, and comments about how they will finally settle things from 500 years ago. As the devil has his creature attack them, Lemiel and Licht each use spells to destroy the creature. While Zagred analyzes what the two had done, Licht gets beside the devil and fires a spell. Zagred dodges the spell, but Licht manages to absorb the spell and fires the spell at the devil. Zagred dodges again and thinks about how Licht and Lemiel are to fast for him to counter with his Kotodama Magic. Lemiel manages to land a blow on Zagred, but the devil counters by conjuring a trident and ripping off Lemiel's arm. Before Zagred has the chance to finish attacking Lemiel, Asta charges into the battle and counters his trident with his sword. Zagred uses his magic to force Asta away, and has it rain swords at him. As Asta starts to counter the swords, Lemiel, Licht, Yuno and Patolli show up and help him. Secre then helps Lemiel, by using a spell to reattach his arm. Asta is amazed by what Secre did and comments about how he feels that he knows her, but Secre tells him to focus the battle. As Zagred comments about how worthless all magic is against him, Secre tells the devil that he will be take down by the people that he sees as worthless. Zagred says that they should speed things up, commenting about how the only exit is on this floor and that the ones on the lower floor will be consumed by his creature before they finish him. Licht tells Zagred that all their power will finish the devil off, which Licht uses his sword to absorb all of the power of the elves. After absorbing all of the elves power, Licht unleashes a spell that obliterates the Zagred's body. As the others are amazed by what Licht had done, but notices that the devil's heart is still intact. Zagred then uses his magic to restore his body. Asta thinks about how powerful Licht's sword is, and wonders what his sword is capable of doing. Asta decides to unleash his power and releases his Anti-magic. Lemiel notices Asta's sword, which Secre informs Lemiel that Licht's grimoire has become a five-lead grimoire and that another devil might dwell within Asta's sword. As Asta tries and fails to unleash and control the power in his sword, Yuno uses the remnant magic in the air to create a sword that is capable of harming the devil's creature, while asking Asta how long he plans to lag behind and to stop fooling around with his power and control it before he leaves him behind. Asta replies that he has just figured it out, and uses his Anti-magic to upgrade his sword. As Lemiel thinks about what Yuno had done but wonders who Asta is, which Secre tells Lemiel that Asta is someone that has worked harder then anyone else in the kingdom while not giving up.

Zagred has his creature attack, which Asta and Yuno easily counters the attack. Yuno uses his magic to push Asta towards Zagred, which Asta manages to pierce the devil with his sword. Suddenly multiple mouths appear all over the Zagred's body, and uses them to force Asta away and have his creature multiple faster. While Patolli defends against the creature, Lemiel and Licht tells Patolli that they are leaving this area in his care while they help the others on the lower floor. As Zagred says that its now over, Asta and Yuno tell him that its not finished until they take care of the devil. Secre thinks about how she originally wanted to use Asta but changed her mind after seeing all the hard work he had put in, and tells Asta to win. Zagred has his creature attack Asta and Yuno, which the two easily counters the attack. Asta and Yuno head towards the devil, but Asta suddenly feels a pain and notices that he is reach his limit. Licht and Lemiel then uses a spell to protect the elves along with those around them, from Zagred's creature. As the creature goes to attack Lemiel, Licht, and Secre, Patolli protects them with a spell. As the creature goes to attack Asta, Yuno comes to his rescue. Zagred sees this and tells them that this is were they will meet their end, and has his creature attack again.

Secre is watching the two and thinks about how she had thought that Asta would never be able to be like Lemiel. As the creature attacks, easily counters it. Yuno notices Asta and wonder if he is already at his limit. Yuno tells Asta that he will leave him behind if he cannot keep up and head towards Zagred, which Asta quickly chances after him. The devil sees this and thinks about how Yuno cannot cut through his heart, while Asta will will not be able to cut through his heart. Zagred notices that Asta had gotten behind him, and thinks about how Asta used the remnants of the shredded magic in order to get behind him. Asta and Yuno manages to reach Zagred and cut into him. Suddenly Asta's Black Form comes undone, which Asta thinks about how he is has reach his limit. Zagred forces Yuno away, then starts to taunt Asta. Yami then launches his spell and manages to cut the devil in half. While the others are shocked by this, Zagred is confused about how this can happen. Secre uses this chance to heal Asta's wounds with a spell and thinks that Asta should be able to summon his Anti-magic. As Zagred goes to attack, Yuno shows up and stops him. Asta then uses a spell to cut the devil in two, finally ending the battle.

Licht, Lemiel Silvamillion Clover, Patolli, and Secre Swallowtail are shocked by the sudden victory. Patolli and Secre remember everything that has happened in the past, and Secre thanks Asta and Yuno for what they did. Yuno holds up an exhausted Asta. They then notice that the devil's spell is not disappearing and is counting to devour the Shadow Palace. Licht warns that the structure is collapsing. Yuno thinks about how they have to get out of the Shadow Palace but there are people among the lower floors. Lemiel's body is beginning to give out so the magical protection will not last. As Lemiel's magic reaches its limit, and the protective light disappears, Asta yells in terror at the fate awaiting those below. However, a portal appears and drops the assorted Magic Knights and elves on top of Asta and Yuno. Rades Spirito and Valtos appear from another portal, and Valtos explains that this is the first step in his atonement. Patolli is reminded he too must atone for William Vangeance's situation. Suddenly Yami shows up with Charla, Revchi Salik, and Gueldre Poizot in tow. Asta notices that Revchi and Geuldre are with the captains, Lemiel is fascinated by the odd magics and consders the Clover Kingdom to be in good hands. With everyone gathered, they all head to the exit.

While they are all exiting the Shadow Palace, Charmy tightly hangs onto Yuno much to Sylph's anger. Asta notices that Charmy has returned to normal and comments about it, which Charmy replies that she has always been like this. Asta and Mimosa become confused by this and wonder if they were seeing things. As everyone begins to enjoy their victory in the Shadow Palace, Nozel comments that the battle is not over yet. Once they arrive back at the kingdom, Nozel tells them all that they have to stop the rampaging elves that are still trapped by the revenge ruse they were all tricked into. Noelle wonders how they can stop them, which Mereoleona suggests that they roast them all. Asta is frustrated since he is too worn out and unable to use all of his power. Patolli says that they still have a chance since Licht's and William's magic will be able to reach everyone in the kingdom. Valtos appears before Patolli and gives him William's grimoire, which Patolli thanks him. Valtos also comments about how it does not matter who Patolli is, since it was Patolli that had saved him that day. Patolli then asks Asta to undo his reincarnation with his Demon-Destroyer Sword, which Asta asks if he is okay with this. Patolli tells him that by doing this will help him to repent for everything that he had done, since simply just disappearing will hardly be enough for him to atone for everything that he has done. Patolli tells everyone that he will be leaving first and asks Licht to take care of the rest, which Licht says that he will. Asta then uses his Demon-Destroyer Sword on Patolli, which Patolli thinks about how he is happy that he was able to fight with everyone once again.

As William awakens, he notices that Patolli has laid his anger and grief to rest and passed on. William then thinks about how its not over yet and that there is still something only he can do, and starts to use his world tree magic. As William starts to spread his World Tree Magic throughout the kingdom, William thinks about how he was not able to believe in the future of the kingdom when he had glimpsed Patolli's past. William also thinks about how it was his weakness that brought on this war, and that now he must create the foundation in order to end it. Once it is complete, William and Licht combine their magic to reach all the elves and reveal the truth to them all. Licht then tells Asta to use the Demon-Destroyer Sword on the tree, which Asta does. As the Reincarnation Magic becomes undone throughout the Kingdom, Asta tells Licht that the grimoire and the swords in them are his, which Licht says that the Grimoire already belongs to Asta now and to let it travel with him down whatever path lies ahead in his future. The elves then pass on and thanks the present day Magic Knights of the Clover Kingdom for what they have done, as the rest of Kingdom is finally exorcised of the elves' spirits.

Later the Magic Knights begin to help the citizens of the kingdom, while commenting how the long battle is over. Mimosa is healing Asta on top of a tower, while Noelle comments about how Asta had pushed himself too far once again. Lemiel expresses his gratitude for their help with dealing with the devil, while also thinking about how they used the power of another devil. Noelle and Mimosa wonder who Lemiel and Secre are, even though Lemiel looks like the statue of the first magic emperor. Asta reveals that Lemiel is the first magic emperor and expresses that he will become a great magic emperor just like Lemiel. Asta says that Secre is Nero, which Noelle wonders if Asta had hit his head somewhere. Secre says that Asta is correct, which Noelle is shocked by this. Asta expresses how amazing Secre is for being able to transform into a human, which Secre reveals that she was originally a human. Asta wonders why she did not say anything, which Secre says that she did not get a chance to talk to Asta until they escaped from the Shadow Palace. Secre then pinches Asta's cheek for talking so brazenly to Lemiel, which Asta tells her to stop and how she is still the Nero that he knows. Lemiel tells them that he never cared about being the magic emperor, and that he is glad that his ideals have lived on in Asta and Yuno. Lemiel then asks which of the two would become the next magic emperor, which Asta expresses that it will be him. Secre says that Asta and Lemiel are on completely different level, which Asta is shocked by her response.

Lemiel's body starts to crumble, which Lemiel says that his mana is starting to run out. Noelle, Mimosa, and Asta are shocked by this, which Mimosa wonders if her magic can help. Lemiel asks Secre to do her part in guiding the kingdom towards their ideal, but Secre expresses her desire to stay with Lemiel forever. Lemiel thinks about how he feels such content that he was able to meet his own descendants. Secre tells Lemiel that she was happy being able to serve him, which Lemiel says that it was the same for him and thanks her for all her hard work. Asta, Mimosa, Noelle, and Secre then watch as Lemiel's body crumbles away.

The next day, in a part of the Clover Castle's wall, Julius and Yami call together a meeting with Asta, Noelle, Mimosa, and Secre, who are uncertain who the kid standing in front of them is. Julius explains that the kingdom is faced with three problems. The first is the lack of a Magic Emperor, with Yami pointing out that Julius is in fact the kid, surprising the others. Julius explains that his magic power and grimoire are limited and that his influence with the nobles has weakened. He then explains the other two problems, the second problem being that a foreign nation will destroy the Clover Kingdom if it does not change. Asta wonders if it could be the Diamond Kingdom or another country. Julius then says that the last problem is that Asta will die and that both could happen. Asta and Noelle are left stunned by the revelation.

After hearing this Asta immediately panics and asks why he will die, with Yami exclaiming that Julius is usually right about these things and jokingly bids Asta to rest in peace, with Asta asking why Yami was so sure that he would end up dead. Asta asks Julius what is the meaning of all this, to which Julius responds that Asta's power comes from a devil. Asta then remembers feeling a similarity between his black form and the devil he defeated in the Shadow Palace, with Noelle and Mimosa both questioning Asta about whether he is okay, to which he states that he's fine. Yami is creeped out that Asta is associated with a devil, and Asta points out that Yami's bluntness hurts. Julius then explains how the horns that Asta obtains in his black form is the sign of a curse called Weg. Julius explains how the curse is from someone using the power from the realm of the devils, which Secre explains how she obtained horns from using a forbidden spell and now she is able to transform into a bird at will now. He then hears Julius explain about the three kingdoms bordering the Clover Kingdom, and how the Spade Kingdom would likely take the opportunity to attack now that the Clover Kingdoms' knights are exhausted and divided from the battle with the elves. Asta says that it was all the devil's fault, which Julius explains how the Magic Parliament will condemn the devil's power and make Asta the scapegoat since he uses the power of a devil. Asta wonders who will run the Magic Parliament, which Julius says that the royal house of Kira is in charge of that.

Several days after the meeting with Julius, Asta and Secre are called to the Magic Parliament building for a talk. Though Asta figures it will be just a normal chat to inform them of the events that occurred, he and Secre are immediately handcuffed by some guards and are brought before the Magic Parliament and its chairman, Damnatio Kira. Damnatio intentionally reveals Asta and Secre's status, with Asta as an orphan peasant and Secre's history being unknown, and with their unknown powers as well as the fact that Secre has horns which means she has delved into Forbidden Magic. This causes the members of the court, who are all noble and royalty, to immediately distrust Asta and Secre which causes Secre to remark how despite Julius's best efforts he could not change the views the upper class have on non-nobility. Damnatio approaches Asta and quietly tells him that either he will take the fall for the possessed Magic Knights as a devil user or the possessed Magic Knights will pay for the actions they committed while under the control of elves. Damnatio feels assured about this because his magic lets him know that Asta is the person who will not let the other Magic Knights die. Damnatio then asks Asta about this supposed Devil which though Asta tells him about he is not able to show him as no one but a small group of people saw the devil. Secre prevents Asta from talking about his own devil and Damnatio announces aloud to the Parliament members that since there is no devil that they will just have to punish the possessed people. He then brings out Marie and plans to have her executed to provoke Asta into saving Marie thus revealing his demonic powers. This plan works as Asta immediately uses his form to stop the executioners attacks. Asta states he refuses to accept Damnatio's sense of Justice to which Damnatio replies that the people will never seek cooperation with a devil.

Damnatio then tells Asta to surrender in order for the formerly possessed Magic Knights to avoid facing charges for what happened during the Elves' assault on the kingdom. However, the Black Bulls break into the courtroom from the side of the building and tell Damnatio to release Asta and Secre as they belong to their squad regardless of the Demonic presence surrounding them. Secre tries to get them to take Asta and leave but they assure her that she is a part of their group regardless of her attempt to use them. Damnatio breaks up the group conversation by telling them that their actions will not make Asta's situation better but only worsen the charges placed on him. He then uses his Scale Magic spell, Scale Regulate, to weaken their magic to a balanced level to prevent their interference. However, Asta pulls out his Demon-Destroyer Sword's ability to cancel out Damnaio's ability on the Black Bulls. Damnatio is shocked by this new ability which allows Yami to move in to try to knock him out. Suddenly, Fuegoleon and Nozel come down to break up the confrontation while also bringing in Julius's new order for the Black Bulls to investigate the devils. As Nozel and Fuegoleon are royals, this convinces the Magic Parliament to allow Asta to prove his innocence, ending the trial. Damnatio cautions Asta that he will still be executed should he fail. Although Asta is relieved that everything is over, still confused he asks Yami what exactly is going on, with Yami telling him to get ready to take a trip out of the Kingdom to prove his innocence.

Asta and Secre later accompany Yami to see Charlotte Roselei, in order to ask her more about her curse, however the conversation ends with the Blue Rose captain running out of the building from Yami, to the shock of everyone, including Yami himself. Later Asta accompanies Yami to Blue Roses' base to try to ask again, with Charlotte trying to confess her true feelings to Yami, only for him to mistakenly think that she must really hate him. Asta tells Yami that he is wrong, and that he does not get the feeling that Charlotte dislikes Yami. Yami grabs a hold of Asta and says who asked for his opinion. Asta explains that he gets the same feeling that Noelle has with him, which is trust. Asta also explains how its harder for Charlotte to be honest with him, the more that she trusts and relies on him. Yami asks if Asta is now embarrassed about proclaiming that Noelle trusts and relies on him. Asta replies that he and Noelle are comrades that have walked the line between life and death, and have come out on top countless times together. Asta also says that Noelle just cannot be honest with herself. Asta then pats Charlotte on the back and tells her that she should just be like she always is since she is too embarrassed to say what she wants to say. Sol then starts to choke Asta, for touching Charlotte in such a familiar manner. Charlotte comments about how they are blessed with such wonderful knights in their squads, which Yami replies that its also because of Asta that they are currently in trouble. Charlotte then tells Asta that she had heard what had happened to him and apologizes for it, but Asta tells her that its not her fault since she was possessed. Charlotte asks Yami to join her for dinner since there is something that he wants to discuss with her. Yami agrees to it, but thinks about how he does not get what is going on here.

After hearing from Charlotte about her curse, and after being told by her to look into one of his own squad members, Yami orders Asta, Gauche, Grey to go with Gordon to talk to Gordon's family about curses. After dinner, Gordon asks his father to teach them about devils and curses. Nathan shows them his workshop, which horrifies them, but he then uses his magic on Asta and reveals that he has been using his research to create treatments and cures instead of curses, which surprises Gordon. Nathan then creates a map that shows the locations of curses throughout the kingdom, with one of the locations being the black bull's base, with Asta realizing that it might be Henry that there seeing, and then they notice a particularly powerful one coming from in the Heart Kingdom.

Yami informs his squad that they cannot infiltrate the Heart Kingdom, because of the kingdom's trap magic that is at their borders. Noelle tells Yami that Mimosa had been to the Heart Kingdom and that they are currently studying there too, which Yami tells Finral to get on it. After heading to the Golden Dawn's Base, Asta and Noelle meet with Mimosa about her time in the Heart Kingdom. Mimosa tells the two that she had studied aboard with her brother in the Heart Kingdom, and explains everything she had experienced while there. Mimosa also explains how power the princess of the Heart Kingdom is and that she sees everything that happens within her kingdom. Mimosa then tells the two that she will help them out by handling the applications to enter the Heart Kingdom, which they thank her for. Sometime later, Asta, Mimosa, Noelle, Secre, and Finral are all heading towards the Heart Kingdom on a boat. As the boat enter through a fog, Mimosa explains that only those that have permission from the Heart Kingdom may enter the Heart kingdom. As the boat exits the fog, Asta, Noelle, and Finral are amazed as they witness the Heart kingdom. At another location, the princess notices that Clover Kingdom's power of the devil has arrived and comments about how she must have that power. As Finral and the others wonder were they should dock, a mage from the Heart Kingdom named Gadjah greets them and tells them to just continue on. As they wonder were they can go since they have reach an end to the river, a staircase suddenly appears and the boat continues on. As they are amazed by this, Gadjah reveals to them that the mist barrier and rivers are all controlled by their princess's mana zone. Gadjah also explains how since the beginning of their kingdom's founding, their rulers have pledged their devotion to the water spirit in order to borrowing the spirit's power. Noelle comments about how one princess is capable of protecting a country this massive, which Gadjah says that the princess is capable of for now but the future remains uncertain.

Suddenly Asta is surrounding by water and taken off the boat. As Noelle and Mimosa wonder what is going on, Gadjah tells them that they need something for the sake of their own peace. Asta is pulled down into the underground chamber of the Heart Kingdom and lands face first. There he encounters a group of armored knights, a spell cast by Undine, the spirit of water. Undine apologizes for bringing him in on that manner and attempts to strike Asta. More armored knights are created and Asta activates his black form and uses Black Hurricane to wipe them all out. Undine then appears and greets Asta, calling him a devil. Undine then pulls Asta into a whirlpool and tells he has no magic and is less than a Ninth Stage Mage. Undine explains what magic stages are and binds Asta's hands and secures the manacles to the floor underwater. Secre then flies in and says that magic is not based on one person's magical talent. She uses her magic to break the chains, which surprises Undine. Asta then uses his Anti Magic and Ki-sensing ability to find the princess and breaks down the water barrier that was surrounding her. Asta then barges into Lolopechka's room and startles her, causing her to accidentally headbutt him. Undine pulls Asta away from her and comforts the Princess. Lolopechka explains that they were testing the Magic Knights, and when Asta asks about the curse they were following, the Princess reveals that she is the cursed one. After Gadjah brings the other Knights to her palace, Lolopechka asks for their help but then trips and stumbles, dropping her regal demeanor. She explains the situation with the devil Megicula, and asks Asta and Secre for the help of their magic, explaining how because of their rare abilities, they are both considered Arcane stage mages. Noelle and Asta contact Yami for permission, but he is too busy in the bathroom, which Lolopechka finds amusing. Mimosa instead contacts Marx Francois and Julius Novachrono. The Princess and the Magic Emperor discuss the arrangement and agree to an alliance. She admits that they are all too weak to defeat Megicula, so she decides to have her Spirit Guardians train the Magic Knights for six months.

Six months later, after being informed by Lolopechka about a Candelo draining power from the weaker Spade citizens, Asta leaves immediately and flies straight towards the fortress. He sends the Demon-Slayer Sword through a window and stops a soldier who is attempting to assault one of the women. Landing in the fortress, Asta calls the Demon-Slayer Sword back to his hand and analyzes the situation. The soldier recognizes that Asta is a Magic Knight from the Clover Kingdom and mocks him for lacking mana while forming a huge suit of armor. The soldier boasts that he can defeat Asta in an instant. To his surprise, Asta cuts through the armor and knocks him out in one blow. Asta then challenges other soldiers and defeats them quickly.

Asta introduces himself to the prisoners and reassures them that he will not harm them. The woman cries out about their situation and feels hopeless since they cannot escape either the Grand Magic Zone or the captain possessing inhuman magic. Sensing that the people are frightened, Asta claims that he will defeat all the soldiers, but is suddenly interrupted as the enemies drop down and start attacking. Asta quickly draws out his Demon-Dweller Sword and slashes the enemies using Black Slash. Sensing the captain's ki up above, Asta charges through the ceiling and defeats the other soldiers present, while making his way towards their captain. Asta cuts open into the captain's room, and the captain senses that Asta shares the power of a devil. Asta questions the captain on mistreating his own people, to which the captain replies that they were mere sacrifices for the prosperity of Spade Kingdom. Asta is suddenly paralyzed as the captain's Poison Magic starts spreading through Asta's body. Asta uses the Demon-Destroyer Sword to erase the poison, which astonishes the captain. Asta enters his black form and compares their level of devil power. Asta adds that he will crush them all for sacrificing their own people, and uses Black Divider to cut through the captain's spell and the upper portion of the fortress while the image of the Anti Magic Devil looms above it. Meanwhile, Noelle flies towards the Candelo while carrying Mimosa and Finral.

Asta drags the knocked out captain down to where the prisoners are and informs them that he has defeated everyone so they can relax now. Noelle reaches the Candelo and releases her spells, dousing Asta and Finral in water. Noelle complains on how hard it was on her to maintain a transport spell in Grand Magic Zone and inquires Asta on leaving them behind. Noticing the woman who was assaulted by the Spade soldier, Finral tries to flirt with her but backs off as he remembers that Finesse Calmreich is the only one for him. Mimosa's Princess-Healing Flower Paradise recovers the people's stamina. Noelle notices that the people are still sad, since they have lost their home to the soldiers. The woman replies that the soldiers were cruel enough to kill the people who resisted and they will be killed immediately even if they return. Noelle smiles and asks them not to worry as Leopold and Luck have headed to the town to defeat the spade soldiers. After retaking the town, Luck and Leopold informs Asta and the others that they have finished their work, with Asta complimenting them on their work and complaining about how Leo has gotten taller in six months and he has not. Finral marks the current location and heads to the town. Observing their progress, Lolopechka is happy that it ended well but realizes that the real battle is yet to begin. The woman inquires what they are going to do to the town since they need to obey the strong in order to live. Asta smilingly replies that it is their town and that the Magic Knights will not be doing anything, and informs them that Finral will teleport them all back, which delights the prisoners. Asta says that their role is to defeat the devil in the Spade Kingdom. The woman reveals that the Spade Kingdom is currently being ruled by mages known as the Dark Triad and how their strength is almost like that of a devil.

Later in the Royal Palace of the Heart Kingdom, Lolopechka thanks everyone for successfully completing their mission and guarantees the safety of Tolon, the town which they liberated. Lolopechka adds that as they gain more Spade Kingdom territory, the will corner the devils. Although it is a difficult task, Noelle feels hopeful since they have Lolopechka's support. As the Magic Knights discuss what to do next, Asta, Luck, and Leo decide that they wish to spar with Gadjah. Lolopechka wants to join the training but trips and falls. Noelle suggests they have a bath since they returned from a long travel to a Grand Magic Zone. Lolopechka, Noelle, Mimosa, and Secre decide to go for a bath but a villager rushes in for help, stating that Charmy has appeared in the Polnfrume Forest. Finral steps in to take care of the situation, but Asta convinces him that he can take care of it. Asta summons the Demon-Slayer Sword and flies off from the castle, while Finral reflects on how much Asta has improved. In the Polnfrume Forest, Asta finds a fat Charmy and tries to dissuade her from eating more. Charmy refuses and uses her Cotton Magic and Mana Method to form a giant sheep. As Charmy continues causing trouble, the Spirit Guardian Potrof and Asta team up to go against Charmy, but they fail again and Asta gets stuck in the cotton. Rill Boismortier then arrives and freezes the sheep, allowing for Asta and Rill to shatter the cotton. Rill advises Charmy to avoid overeating, and then paints the goddess who saved him while he was possessed by Lira. Asta explains to Rill that it was Charmy who saved him, but Rill refuses to believe it.

Later, As Finral and Asta arrive at the Black Bulls base, which is now near the border of the Spade Kingdom, they bring with them snacks from the Heart Kingdom. They are greeted by Vanessa Enoteca, Grey, and Gauche Adlai. After being greeted, Asta asks where the others are, with them stating that Gordon is still studying Curse Magic with his family, Henry is resting to recover his mana, and Magna and Zora are off traveling together again. Finral remembers that the captain conference will be ending soon and heads out to go pick up Yami. After Finral leaves, Henry wakes up and informs the others that there is something wrong. They then notice that their base is floating in the air, with one of the Dark Triad, Dante Zogratis appearing before them.

Dante Zogratis decides to play with them until Yami returns. Vanessa quickly sends out Rouge, and the base stops moving. Henry rearranges the base and attacks with his Mana Rocket Punch, while Gauche also attacks with his Large Reflect Refrain. Dante uses his Gravity Magic to cause the spells to fall to the ground along with everything else around him. Gauche comments about how powerful the spell was, while Vanessa says that they would have also been snapped in half if it were not for Rouge. Dante comments about how he likes how the Black Bulls have an arcane mage that can manipulate the natural law.

Asta attacks with a Black Slash, but Dante dodges it. Asta then charges at Dante and says that he will be fighting him. As Asta fires more Black Slashes at Dante, Dante tries to uses his Presence of the Demon King spell on the attacks, but it does not work. Dante dodges the attacks, and thinks about how Asta has negated his magic. As Dante uses his magic to have the fallen trees attack Asta, the trees miss and Dante thinks about how the spell that interferes with the natural law has activated again. Asta attacks, but Dante dodges and heads into the Black Bull base to find the owner of the spell Vanessa. Asta charges at Dante, but Dante uses his magic to cause Asta to fall to the ground. Dante comments about all of Vanessa's attributes and tells her to be his woman, Dante of the Dark Triad.

Asta suddenly appears behind Dante in his Black Asta form. Dante gets away from Asta while commenting about how there was someone that was possessed by a devil in the Clover Kingdom. Asta attacks with his Black Divider spell, but Dante dodges it. Asta uses his Black Meteorite to chase Dante, but Dante uses his magic to keep himself away from Asta. Gauche comments about how they show use of a spell that Dante cannot avoid, and uses his Mirrors Brigade spell to create multiple Astas. All of the Astas attack with Mirrors Meteorite. Dante counters by using 50% of his power and uses his magic to warp space, to divert the attack. Asta wonders what happened.

Dante steps on Asta and forces him to the ground. Dante tells Asta that they should be able to see eye to eye since they are both possessed by a devil and explains how their dark emotions make them more human. Asta disagrees with him and says that it is his strong heart that makes him more human. Dante says that Asta is a strange devil host and tries to kill him, but notices that Rouge is on Asta's back. Vanessa says that Dante will not be killing anyone while she is around. Dante tells her that she cannot use her power for anyone other than him. Dante increases his power to 60%, which causes Vanessa to expend all her magic and Henry loses control of the base. As Gauche, Vanessa and Grey are suspended in the air, Gauche thinks about how Dante is using his magic to pin them down. Dante then uses his Evil God's Pressure Craft to create a sword, and says that he will awaken Asta's true feelings as he pierces Gauche with his sword. Asta sees this and remembers someone calling him their son. Overcome with rage, Asta draws on more of the devil's power and attacks Dante. Dante dodges the attack and comments about how that is what make Asta more human.

As Vanessa, Grey and Gauche fall to the ground, Vanessa thinks about how Asta's attack has negated Dante spell within the area. Asta starts to assault Dante, but Dante dodges by continuously warping space around him. Dante then asks his devil, Lucifero, about the devil within Asta since he cannot ask Asta right now. Lucifero says that Asta must be a low-level devil since he does not sense that it is the high-level devil Zagred. Dante figures that Asta is no match for the Dark Triad, since they are all possessed by high-level devils, and uses his magic to lift large chunks of earth from the ground. Dante attacks with one of the chunks, but Asta easily destroys it. Vanessa sees that Asta's power is running wild, but they have to rely on him for right now. Vanessa then turns her attention to Gauche and thinks about how he will not last for long, while Grey is crying over Gauche and thinks about her Transformation Magic is useless. As Asta continues to charge at Dante, Dante uses his Evil God's Pressure Craft to create more swords, and attacks with them. Asta uses Black Hurricane to defend himself and also fire a Black Slash at Dante. Dante warps space to dodge the attack, but Asta predicts where Dante would dodge to, and manages to wound Dante's face. Dante decides to get serious and start to use his Heavy Infighting spell to assault Asta. As their fight continues, on the ground Grey, who's reflecting on her past manages to use her magic to heal Gauche. Suddenly, Asta falls to the ground. Dante sees what Grey has done and comments about how the Black Bulls have another arcane mage. Dante comments about how both Grey and Vanessa should both become his women, but suddenly a dark slash divides Dante from the others. As Dante notices Yami, Yami asks him what he is doing since nobody messes with his people.

Dante is glad to see Yami, along with the malice that Yami is giving off, but uses his Presence of the Demon King spell to force Yami and Finral to the ground. Yami manages to keep standing, but uses his Black Moon spell to create an area that negates the effect of Dante's spell. Dante notices how the spell works and throws a boulder at Yami, who easily cuts it in half with his Dark Cloaked Dimension Slash spell. Dante use his Heavy Infighting Gladiator spell to create a sword and attacks Yami in close combat. Asta, still laying on the ground, manages to regain consciousness in time to see the two fight. As the two clash, each of them notices what the other are capable of. Dante is excited to see Yami's capabilities, and Yami asks if Dante is some kind of stalker. As their battle continues to intensify, Yami manages to inflict a major blow to Dante after using a Mana Zone technique. However, As Yami comments about how his spell never misses, Dante laughs and uses a different magic spell to heal his wound. Dante comments about how he excited and that nothing originally satisfy him his malice before. Dante also comments about Yami is the key that would open this world to be far more magnificent. Yami wonders what Dante is talking about, so Dante explains how he needs a Dark Magic and World Tree Magic users in order to create the magic channel, the Tree of Qliphoth, in order for the devils from the underworld to pour out and into this world. As Dante laughs about this, Yami says that he will have to wipe Dante out right here.

Yami continues to attack Dante, learning more and more about his magic and the limits of his devil powers. After realizing that he needs to hit him at close range, Yami then continues to dodge and blocks Dante's attacks until he figures something out. Dante however, manages to slam a chunk of earth on Yami, but Yami gets up and proclaims that he will surpass his limits. Dante says that Yami will not be able to defeat him, but Yami uses his Death Thrust spell to obliterate Dante's chest. Dante laughs and starts to regenerate his body, while explaining how his original magic is Body Magic and that the devil's power boost his magic to the point where he is unable to die. Dante then transforms into a monstrous form and comments about how he is grateful since he is able to go all out. Dante continues his assault but Yami dodges them all and then lands another Death Thrust spell. Dante heals himself again, and explains how Yami cannot defeat him and that there is no one that is capable of defeating him. Asta sees the fight and becomes frustrated that he is not able to do anything. Yami stop and says that he is not able to defeat Dante. Yami also says that he needs Asta's help. Asta calls forth his sword and quickly gets to Yami's side.

As Dante gets excited to face the two, Yami tells Asta to follow his lead which Asta agrees to. As the two charge, Dante tries to block their charge but the two easily break through. As Yami manages to continue to wound Dante, but Asta has trouble and needs Yami's help. Yami figures that Asta's Anti Magic is the key to winning this fight, while Asta thinks about how he is holding Yami back. Asta figures that he needs to all the power that he does not know about, and manages to meet with his devil. Asta asks the devil to lend him some of its power since he knows that the devil wants to defeat Dante, too. The devil replies that it will lend him power but will need to take control of a part of Asta's body. Asta explains how he wants to be someone that can come through for Yami before becoming the Magic Emperor, with his right arm now transformed due to the power he gained from his devil.

As Dante launches his Gravity Singularity spell, Asta uses the power of the devil to destroy the spell and proclaims that this is everything that he has right now. The devil explains the power that Asta is wielding is more powerful then the dribble that he was giving him and that Asta will only have fifty seconds to use it, to which Asta replies that that is long enough. Asta manages to land a hit. Dante notices that he cannot heal the wound that Asta landed on him, so he quickly forces Asta away, creates more arms, and creates swords for each hand. Yami notices that Dante is being cautious of Asta, and figures that they can win if Asta lands a blow on Dante with the power that is radiating from Asta's right arm. Yami decides to put more into the fight and attacks Dante. Finral watches the fight and notices that Asta and Yami seem like they are in sync, even through they are moving randomly, and that the two look like they are having fun.

Dante says that he will crush them and win. Dante then manages to knock Asta's sword away and makes sure that Asta cannot retrieve it. As eight seconds are left, Asta calls for his Demon-Dweller Sword but Dante blocks it before it can reach Asta. When Asta tries to draw out his Demon-Destroyer Sword, Dante stops it, too. As three seconds remain, Dante attacks Asta but Yami stops him with his Death Thrust. Dante says that he is indestructible and regenerates his wound while proclaiming that it is over. As one second remains, Yami passes his katana to Asta, who grabs and imbues it with Anti Magic. Asta manages to land a slash on Dante, who falls to the ground. Dante's transformation is nullified, and a large gash stretches across his torso. As Asta collapses, Yami catches him and compliments him on a job well done. Yami then gives Asta to Finral, and heads over to Dante to seal him with a spell. Suddenly Zenon appears and retrieves Dante, while also capturing Yami. Zenon notices Asta and tries to kill him, but Finral uses his magic to divert the attack. Zenon notices that it is time to leave and opens a portal. The Black Bulls try to stop Zenon, but Zenon easily counters all their attacks. Asta tries to get more power from his devil, but the devil says that Asta is too weak to handle any more of its power. Zenon then takes Yami through the portal, which shocks the members of the Black Bull.

At a hospital in the Clover Kingdom's capital, Owen examines Asta using his Qualle Operation spell and determines that Asta's life is not in danger and that he cannot do anything about Asta's right arm. Later, Asta wakes up and notices his arm. Suddenly, Yami's katana appears from his grimoire. Remembering what happened, Asta rushes out of the hospital. However, when he steps outside, he finds that he cannot move. A person appears behind him and asks where he is going. Asta wonders who that is and if it is their magic that is restraining him. Asta says that he has to go save Yami. The person explains that Asta is no match for Dante Zogratis on his own and that there are two other devil hosts who are just a strong as Dante. The person also says that Asta's devil has given up on him and that Asta does not even understand his own arm. The person explains how going there is not courageous but just stupid and reckless, and then goes on to say that he knows a lot about Yami and that he is an idiot if he really did lose.

Angered by the statement, Asta attacks this person, but is quickly restrained to the ground. The person says a human who cannot defeat him will not be able to rescue Yami, which reminds Asta of the devil calling him weak. Asta starts to cry and wishes to be stronger. While removing their hood, the person calls Asta a fool but admits to liking him because he is a good person. He then takes his hood off and introduces himself as Nacht Faust, the vice-captain of the Black Bulls, as well as revealing that he knows how to use a devil's power. He then introduces his devil, Gimodelo, before releasing his spell on Asta. Asta then asks where he has been, with Nacht explaining that he has been undercover in the Spade Kingdom the whole time, as well as stating that the other reason he has meet the other black bulls sooner is because of his personal hatred of Yami, which surprises Asta. Asta then asks to learn how to use his devil's power, but Nacht refuses and instead insists that he rests.

The next day, Nacht slips into the captains' meeting and interrupts, complimenting their motivation but criticizing the mess they made of the meeting. He rises up out of a shadow with Asta under his arm. The captains move to attack the intruder, but Nacht uses his devil power to summon four masked beasts to stop them. Julius vouches for Nacht's identity, and Jack notes that Nacht's magic has changed. Nacht hands over the documents from Dante's room and explains the process for the Tree of Qliphoth. Rill Boismortier wonders why the Dark Triad are doing this, and Nacht claims that they are evil and their motivations are incomprehensible. In order to retrieve Yami and William and to destroy the Tree of Qliphoth, Nacht wishes to train Asta and his Anti Magic and to build a team around Asta. Nacht explains his plan to slip into the castle, lists the Dark Triad's names and magics, and adds that the team will have to be limited in size. When Yuno requests to be on the team, Nacht asks who Yuno is since he was visited by a resistance member from the Spade Kingdom. Yuno reveals that he is the purported prince of the Spade Kingdom; however, he wishes to seek revenge on Zenon Zogratis for the sake of William Vangeance and the Golden Dawn squad. After hearing this, Asta says that Yuno is still Yuno, even if he is the Golden Dawn's vice-captain or a prince of the Spade Kingdom. Nacht likes Yuno and Sylph's tenacity and power, and agrees to his request.

Nacht announces that the team will leave on the morning of the third day, Asta then tells Yuno that they will defeat the Dark Triad and rescue their captains. Nacht then leaves the meeting after informing everyone of the situation happening in the Heart Kingdom. After meeting with the other Black Bulls and informing them of the situation, Nacht then rejoins Asta with his Shadow Magic, then takes Asta to an abandoned house that was owned by a former noble. They enter a room of the house, and Nacht touches the floor and pulls them into a secret chamber, where Nacht plans to teach Asta everything he knows about devil magic for the next two days, which excites Asta. Nacht explains that Asta has not been using the full power of his devil and that they will use the Devil-Binding Ritual, a forbidden ritual whereby one makes a contract with a devil and formally makes its power their own. This ritual requires a relic connected to the devil, and Nacht notes that Asta's arm, grimoire, and body are already connected to the Anti Magic Devil. As soon as Asta steps into the magic circle, Nacht summons the devil out of Asta, causing Asta's right arm to disappear. The devil is surprised that Asta would willingly release him. Nacht then tells Asta to fight the devil and win.

Asta does not wish to fight and instead thanks the devil for his help during Asta's previous battles. Liebe points out that he took Asta's arm, but Asta brushes it off as part of their bargain. Liebe says that he will kill Asta and summons the Demon-Slayer Sword from the grimoire. Liebe then coats the sword in Anti Magic, enlarges the blade, swings it down next to Asta, and then smacks Asta with the flat of the blade.

Asta still refuses to fight, so Nacht informs him that if he loses, the devil will take his body and transform him into a monster, which Nacht will have to kill. Nacht dismisses Asta's concerns since they only have two days to improve Asta's abilities. Liebe interrupts their conversation and swings the sword at Asta's head. Asta ducks and the sword smashes into a pillar. Nacht tells Asta that the devil will kill him, which Asta refutes, saying that the devil's ki has no killing intent. When Nacht comments that devils cannot have good hearts, Liebe agrees that all devils are scumbags. Sensing that Liebe is different from Zagred, Asta disagrees that being a devil means being evil. Asta's words and appearance remind Liebe of Richita.

The memories of his torturous time in the underworld, his happy life with Richita, and the sudden interruption by Lucifero infuriate Liebe, who declares that he will steal Asta's body and kill every devil. Sensing the hatred and sadness in the devil's ki, Asta pledges to accept those feelings and defeat the devil in a fight. Liebe considers it a joke and throws the sword at Asta, who dodges to the side and then punches the devil's face. Liebe summons the other swords from the grimoire, but Asta grabs Yami Sukehiro's katana and wields it to fend off the other swords that come flying at him. Liebe recollects how his malice grew while in the grimoire and he developed Anti Magic. Meanwhile, Asta recalls the fights he has had against and alongside other swordsmen, and copies their movements in order to close the distance with the devil. Asta easily overwhelms the devil in close-quarters combat, striking the devil multiple times and knocking the Demon-Dweller Sword from his hand. Asta follows up with a thrust that strikes the devil's forehead. Liebe falls backward, and Asta stands over him and declares victory. A collar appears around Liebe's neck, and four chains pull him up onto his hands and knees before Asta.

Nacht congratulates Asta for winning and informs him that he can make any contract that he desires and can totally subjugate the devil. Asta requests that the devil become his friend. Both Liebe and Nacht are confused, and Asta explains that he has been able to fight because of the devil's power and wishes to learn more about the devil. Despite Nacht's warning about the devil possibly turning on him, Asta points out that he could sense the devil's character through ki. The collar and chains disappear as Asta reaffirms his desire to make a contract of equals. Asta holds out his hand and asks for the devil's name. Liebe reflects that Asta is truly Richita's son and introduces himself, shaking Asta's hand. Matching markings then appear on their left wrists, and Asta's right arm returns.

Stepping into the circle again, Nacht smiles and tells Asta that the contract is unprecedented and foolish but correct. He then merges with Gimodelo and challenges Asta and Liebe as a continuation of their training.

Nacht tells them that the only way for Asta to get stronger is to draw out all of Liebe's power, and to achieve this by uniting. Using his magic, he surrounds them both in shadows. Asta enters his black form to get out of the spell and wonders where Liebe is. Liebe, in miniature form, tells Asta he is on his shoulders. He explains that he thinks his current form is what happens when Asta uses Anti Magic. Nacht says their current condition is not union. Asta asks Liebe how can he use the latter's real power. Unfortunately, Liebe answers that he does not know how as he has never come out to fight before. They start arguing with each other until Nacht interrupts. He tells them that they will have to figure it out as they go along. He attacks them with his spell called "pack". Nacht tells them that the shadows will not go away until they defeat him. As he cycles through his swords, Asta thinks about how his connection with Liebe is stronger, but Nacht points out that drawing out the power will not be easy for Asta since Liebe is not his servant. After grabbing Yami Sukehiro's katana, Asta says that he will surpass his limits, which irritates Nacht, disrupting his ki. Asta senses the disturbance and sends a flying Anti Magic slash, which cuts the edge of Nacht's cloak. Asta decides to name the katana, the Demon-Slasher Katana, and restates that he is going to surpass his limit, which irritates Nacht more.

After two days, Asta and Liebe continue to fail, and Asta notes that the injuries he receives in his black form are shared with Liebe now. The two eat cookies filled with Healing Magic from the Spade Kingdom's Resistance. Once their wounds are healed, Asta suggests a lame idea that Liebe goes along with on the chance of it being successful. When it too fails, Asta and Liebe begin bickering, but Nacht interrupts and informs them that their time is up. He then engulfs the two with his Dark Prison Hunting Ground spell. As Nacht attacks them, Asta enters his black form and notices that he cannot dodge the attacks since he cannot sense their ki. As Nacht continues his attacks, Asta and Liebe wonder why they cannot unite and think about why they want to get stronger. They both resolve not to let the other die. In that moment of shared desperation and determination, Asta and Liebe manage to unite, shining within the darkness of Nacht's spell. Asta manages to release a single slash that cuts through Nacht's spell and negated part of Nacht's transformation, even though the slash did not touch him. Impressed by Anti Magic's and Asta's potentials, Nacht admits defeat.

Although Asta and Liebe achieved a union, Nacht refuses to let them join the mission yet since they need more time to master it. Nacht leaves Gimodelo behind to continue their training. While an Ancient Demon arrives at the Clover Kingdom begins attacking, Asta and Liebe had just finished their training. When the Clover Kingdom was about to get destroyed by the ancient demon, Asta came in his black form, flying past Julius and Damnatio with Liebe on his shoulder and stop the Demon's blast with his black divider, after which he and Liebe together decide to finish the demon off, now entering their union.
