Mimosa Vermillion

"I don't need a reason to save someone who's dying!! Not even if you're an enemy, or from a different race!!"

Mimosa Vermillion (ミモザ・ヴァーミリオン) is a noblewoman of the Clover Kingdom's House Vermillion, one of its royal families, and a 5th Class Intermediate Magic Knight of the Golden Dawn and Royal Knights squads.

Appearance
Mimosa is a 15-year-old girl with a voluptuous build. She has yellow eyes and long wavy vermilion hair with bangs on her forehead. Additionally, she also wears a pair of earrings on her ears.

As a noblewoman, Mimosa wears fancy attires which consist of a puffy cream-colored sweater with long sleeves, white puffy short pants, and a brown corset. Below the corset, she also wears another lighter brown-colored piece of fabric that has frilly edges. The corset is tied at the front with strings. Her footwear consists of a pair of boots that are tightly fit her legs and extends above her knees. They are light-colored and have a split at the top in which are kept together by strings. The boots also have frilly edges below the collars. On top of all of those, Mimosa also wears a dark red mantle, which has a white lining made of similar material as the rest of the mantle.

As a member of the Golden Dawn squad, Mimosa also wears the squad's signature robe on top of her attire. The robe is short and only covers her torso with a hood that has blue-colored fur around the edges. The robe also has a pair of teal ropes coming out of its left-hand side in which connect to the button on the right-hand side. The button also holds the robe together. Additionally, the squad's insignia is positioned at the left-hand side of the robe.

When she is young, Mimosa sports similar hairstyle but shorter extending above her shoulder. Her attires also have a heavy resemblance to her current attire.

Personality
Mimosa is a polite and sweet young girl who does not forget to show her smile when speaking to others. However, it has been said that behind her smiles, she could also give a rude comment as she has been noted to be blunt to the point of rudeness. Her behavior is slightly different than most nobles and royals who like belittling everyone who is inferior to them. Mimosa tends to look deeper than those nobles and royals and appreciate people according to their worth, such as her deep respect of Noelle Silva for her hard work when the other nobles and royals ridicule her for her lack of magic control and her growing affection for Asta and her desire to become stronger because of him.

She is also a rather clumsy person, especially during her childhood where she would hurt herself by tripping when there is nothing in her way.

Biography
Mimosa was born into House Vermillion, one of the Clover Kingdom's royal families. One day, her family visits a poor village, where they see a young girl steal a loaf of bread. Her older brother points out that poverty forces children to crime which forever sullies them to their cores; however, Mimosa notices the girl sharing the bread with a younger child, and comes to believe that such beauty cannot be tainted.

Mimosa spends her childhood days with her cousin, Noelle Silva. Years later, Mimosa begins to attract praises from the other nobles of her house as she is able to quickly master a high-level Healing Magic spell. Additionally, she is rendered unable to defend her cousin while the other nobles are mocking her, even though she knows that Noelle is rigorously training on her own at the ruins where they used to occasionally play.

When she is 13 years old, Mimosa and Kirsch visit the Heart Kingdom and study as exchange students.

After receiving her grimoire, Mimosa joins the Golden Dawn squad because she does not want to rely on her family background in the Crimson Lions.

After a dungeon emerges on the border between the Clover Kingdom and the Diamond Kingdom, Mimosa is dispatched to explore it along with Klaus Lunettes and Yuno. Upon reaching the inner-side of the dungeon, Mimosa witnesses as Yuno suddenly activates his magic to save a couple of people who are struggling against one of the dungeon's traps. She then realizes that one of them is her cousin, Noelle who is a member of the Black Bull squad.

After a few conversations, Noelle's partner, Asta, challenges them to a race to the center of the dungeon, which Klaus accepts. After Mimosa scans the dungeon with her magic, they immediately leave with the use of one of Yuno's magic spells.

Not long after, they finally arrive at the gate to the treasury at the center of the dungeon. Mimosa informs her squadmates about the status of the Black Bull members before she is suddenly ambushed by an attack. The attack manages to wound her significantly and forces her to activate a healing magic spell. Mimosa is then stuck within her spell and defenseless as Klaus and Yuno try to defeat her attacker, Mars. As she is recuperating, she is forced to stay put and unable to help her squadmates while they are being oppressed by the Diamond Kingdom's mage's superior magical power. Asta manages to intercept Mars' attack and saves Yuno in the process.

When Noelle finds her laying defenseless, Mimosa tries to admit her mishap and clumsiness, but her cousin activates a protective spell around her and promises to protect her from Mars. Mimosa witnesses as Asta manages to overpower Mars, a feat that her two squadmates were unable to achieve. After Asta manages to render Mars unconscious and Klaus restrains him with his magic, Mimosa deactivates her spell and claims that she is mostly healed when Noelle asks her about her condition.

The Black Bull and the Golden Dawn members proceed to enter the treasury after Asta forcefully cuts a path for them. Mimosa, along with the others, are quickly amazed upon seeing the treasures stored within the dungeon's treasury. She proceeds to explore the treasury while occasionally playing with several magic items within it.

Suddenly, Luck Voltia warns them to get away from the treasury's door. Unfortunately, Mimosa does not manage to react fast enough as she witnesses Mars critically hurt Noelle. Seeing the level of injuries that Noelle sustained, Mimosa quickly activates her strongest healing spell while encouraging Noelle to live.

Mimosa is noticed by Mars while she is healing her cousin and is left unable to defend herself, as Mars is about to attack them. Fortunately, Asta manages to save them while Noelle regains her consciousness. Mimosa witnesses as Asta releases a water-based attack from his newfound sword. She hypothesizes that Asta's sword has the ability to absorb Noelle's mana that has an affinity towards water.

Unfortunately, Asta did not manage to defeat Mars and receives a critical injury, instead. In that instant, Yuno suddenly defeats Mars through an unknown means and Noelle immediately asks Mimosa to attend to Asta's injury. However, the dungeon starts collapsing before Mimosa is able to reach Asta's side.

After Yuno creates a vessel and Luck carries Asta into it, Mimosa begins to attend to Asta's wounds. Due to the low amount of magical power left in her, Mimosa begins to doubt whether she could heal him. After finally escaping from the collapsing dungeon, Mimosa moves Asta to a safer place near the dungeon and continues her effort. The moment Asta opens his eyes, Mimosa is surprised that Asta could survive his injuries, and Yuno merely mentions that high vitality is one of Asta's virtues. Mimosa is yet again shocked when Klaus hugs both Asta and Yuno, acknowledging both of them.

A week later, after completing the mission, Mimosa and her squadmates are instructed to head to the Magic Knights headquarters in the Noble region to give a report regarding the mission. Along the way, they encounter Asta and Noelle who were given the same instruction. Mimosa, suddenly startled, turns away with a flushed face when Asta greets her. She reveals to her cousin that it would seem that romantic feelings for Asta have started to emerge from their experience during the dungeon exploring mission. Hearing about it, Noelle could only shriek along with her as her reaction. As they arrive at the designated venue, Mimosa and the others are taken by surprise to see the Wizard King himself, Julius Novachrono, is attending to their report.

After a brief audience with the Emperor, Mimosa and the others are invited to attend a War Merits Conferment Ceremony by Julius where he would honor several Magic Knights that had produced tremendous results. Subsequently, they are also invited to a celebratory banquet after the ceremony. Not long after Julius leaves the venue for another matter, Mimosa tries to have more interaction with Asta as he is devouring the dishes served for the banquet.

Mimosa and the other dungeon exploring mission members then become subjects of scrutiny by the honorary Knights. Mimosa receives a harsh critique by Alecdora Sandler, a fellow Golden Dawn squad member, for her uselessness during the mission. She is unable to argue about her performance during the mission and is left speechless when Asta speaks up for Noelle and confronts the Knights for humiliating them.

When someone enters the hall to inform the Knights that the Royal Capital is under attack, Mimosa joins her colleague as they try to figure out a counterattack strategy. She could only be amazed as she watches Asta leave to help the citizens. Mimosa then leaves with Yuno and Alecdora to the Northwest District of the Royal Capital. Upon their arrival, Mimosa and her squadmates are immediately being surrounded by an army of corpses. As her squadmates deal with the corpses, Mimosa quickly puts her attention on healing all of the injured citizens around her.

After all of the corpses are defeated, a Spatial Magic spell activates and the Knights are transported a considerable distance away from the Royal Capital. After combining her magical power with the rest of the stranded Knights, Mimosa is able to quickly return to the Royal Capital. However, once she arrives, she is rendered unable to prevent the enemies from taking Asta away with them.

Subsequently, Mimosa proceeds on treating Fuegoleon Vermillion and Leopold Vermillion where she is perplexed from seeing her cousins' conditions while also worried for Asta. She concludes that with her abilities, Mimosa is unable to completely heal Fuegoleon and suggests the other Knights bring him into a medical ward for advanced treatments. Once her cousins have been taken to the medical ward, Mimosa waits outside of the building when Julius returns with Asta. Mimosa quickly expresses his relief over Asta by hugging the latter.

The noblewoman then has a brief audience with the Wizard King as the latter addresses them of the threat, the Eye of the Midnight Sun. Afterwards, Mimosa shows her delight when Leopold comes out of the medical ward to proclaim his ambition and has a quick banter with Asta. Later on, while strolling through the Royal Capital along with Yuno and Klaus, they encounter the Black Bull members who are about to depart from the city. As they say their farewell, Mimosa promises herself to grow stronger until her next meeting with Asta.

At the Star Awards Festival, Mimosa is happy to see Yuno recognized for his contributions, and is later shocked when Augustus Kira Clover XIII announces the Royal Knights Selection Exam.

A week later, many Magic Knights gather in an arena for the exam, and Mimosa asks Winston to calm down after he releases his magic power in his excitement. Klaus warns her about causing problems with other Magic Knights and comments that she is too relaxed for the exam. However, she loses her composure, blushing and stammering, when Asta greets her and Klaus. For the tournament, she is teamed up with Asta and Xerx Lugner and becomes flustered again.

After reaching the tournament stage, Mimosa finds out that her team is up first. As the battle begins, she tries to calm Asta and Zora Ideale who are bickering and lists off her and Asta's abilities so they can form a plan. Suddenly their crystal is struck and cracks. Moving quickly, Mimosa grabs the crystal with vines and attempts to move it to safety, but it is struck again, surprising her with how accurate the attack is at long-range. After the crystal is struck again, Mimosa smiles nervously as Zora appears to have fallen asleep.

When Zora refuses to help and goes back to sleep, Mimosa uses a spell to sense and map the locations of Team B and warns of an incoming attack, which Asta dispels, shocking her. With one last look at Zora, Mimosa suggests that she and Asta charge directly for their opponents' crystal. While they run, she tracks their opponents' locations and he protects the crystal.

After closing most of the distance, they hide behind a wall, and Mimosa fires Magic Cannon Flower, which is blocked by Curtis Warren's Rock Fortress. Mimosa switches back to sensing when Curtis and Forte Gris dash out from behind the wall, both seemingly carrying their crystal. Mimosa warns Asta about how much magic Curtis is concentrating and then notices that Forte and Rick Cornell have surrounded her and Asta and are concentrating magic as well. Suddenly Asta steps on a paralytic trap, leaving Mimosa alone to defend against the three large attacks.

Suddenly a counter trap appears around Mimosa and Asta and absorbs and reflects the three spells back at their casters, who are knocked out. As she heals Asta, Mimosa questions what happened and notices Zora walking past. When the rogue threatens Curtis, she recognizes the Ash Magic and realizes that Zore set the traps. After Zora destroys the crystal and Team B wins the match, Mimosa finishes healing Asta, who confronts their troublesome teammate. She questions when Zora had the time to set such large traps, but he refuses to answer.

Team C interrupts and Mimosa is embarrassed to introduce her older brother, Kirsch. After frustrating his teammates, Kirsch turns his unwanted attention to his sister, who returns his insults in kind. When he begins insulting Asta, Mimosa grows angry and tells her brother to win his match so that she and Asta can beat him.

After Team C wins the second match, Mimosa and Asta are impressed and disgusted with the display. Asta compares Kirsch to his sister, while she wishes he would not say such things.

Before the fifth match, Mimosa explains to Asta that the name X is for someone who wished to remain anonymous.

Later, in the eighth match, Mimosa is impressed to see Noelle destroy the crystal with a single attack.

Before the first match of the second round, Mimosa protests when Kirsch calls Asta filthy. She is then perplexed that Zora was able to discover the tournament's location beforehand. After her brother covers the battlefield with cherry blossoms, Mimosa struggles to find an opening. Asta's transformation catches Mimosa and Zora by surprise. After Black Hurricane clears the battlefield, Mimosa congratulates Asta.

Asta convinces Zora to work with them as a team, and after Zora explains his abilities, Mimosa senses that Sol has buried her team's crystal within her golem, so Mimosa explains a plan to steal control of the golem. She then sets off on her own while Asta and Zora work on traps. Mimosa confronts Sol and severs the golem's arm, but Sol turns the arm into a Dirt Clod Seal, trapping Mimosa.

Later, Sol bursts from the ground and has her golem punch Team B's crystal, but the punch stops short, and grass sprouts from all over the golem, as Mimosa's magic takes it over. Mimosa forces it to uncover the crystal, allowing Asta to destroy both, and Team B wins the match. Mimosa comforts her distraught brother, telling him that his recognition of the power of commoners and his determination to continue fighting after being dirtied are the most beautiful he has ever been.

During the next match, Mimosa is shocked by the series of explosions from Finral Roulacase's and Langris Vaude' spells cancelling each other. After Asta saves Finral and challenges Langris, Cob Portaport gathers the rest of Teams B and G and drops them off on the battlefield. After Julius explains the rules, Asta apologizes and asks for Mimosa's assistance; she immediately agrees while noting that something is wrong with Langris.

Mimosa carries the crystal while Asta takes the lead and Zora protects the rear. She is shocked when Langris quickly flanks them and unleashes a barrage of spells. When Asta becomes overwhelmed, Mimosa heals his injuries with Princess-Healing Flower Robe. They continue forward but more attacks slip past Asta, damaging the crystal and injuring Asta. Mimosa realizes that she cannot keep up with the injuries, and Zora then jumps in to defend his teammates.

After Langris cancels his own reflected magic, Asta coats himself with Anti Magic and Mimosa shifts to healing Zora. He refuses her assistance, to which she replies that they are teammates and fellow Magic Knights. Just as Asta slices Team G's crystal, Team B's shatters, ending the match in a draw. With the match over, Zora criticizes both teams, pointing out that Mimosa freezes up during battle.

Mimosa accompanies Asta to a room within the audience's platform, and they watch the final match through a magic screen. She looks on as Asta struggles to accept not getting to face Yuno.

Several days after the exam, Mimosa and the others selected to be Royal Knights all assemble in the Royal Capital and are placed under the command of Mereoleona Vermillion. After the squad changes into their new robes and travels to the Gravito Rock Zone's floating dungeon, Mereoleona explains the situation and divides the squad into teams. Yuno infiltrates the dungeon with Mimosa, Klaus, and Hamon Caseus. As they make their way deeper, Mimosa notes that the amount of writing on the wall is increasing and that Yuno has been using Mana Zone.

When the team reaches the central room, they discover a figure floating in a sphere of mana. Suddenly the figure begins shining brightly, and Mimosa suggests that they retreat. She then notices that her teammates are glowing and have changed. The three are possessed by elf spirits and turn on Mimosa. Scared and confused, she asks what is happening, but Klaus disapproves of her familiar tone.

Klaus and Hamon overpower Mimosa and she is secured to a steel cross. She pleads with them but Klaus responds that it is suitable for a royal. Rhya appears overhead and drops Asta into the room, to Mimosa's surprise. The boy promises to help her down but is interrupted, and Mimosa is forced to watch Asta fight Klaus and Hamon. She and Asta are saved by Yuno.

Asta destroys the cross and lifts Mimosa down. She is amazed as she watches Asta and Yuno defeat the two elves. When Licht attacks the boys, Mimosa is too exhausted to heal Asta's injuries. Yuno protects her when Licht blasts the three humans out of the dungeon and down into the water below.

Making it to the shore, they meet up with the remaining Royal Knights. Nozel sets up Eilia's Booth to heal the injured Knights. After listening to a report of the chaos in the kingdom, the Knights set out to save their comrades. As they reach the Forsaken Realm, Mimosa and the others are fully healed. Mimosa smiles when Nozel requests Noelle's help in defending the Royal Capital.

The Royal Knights reach Clover Castle just ahead of the dungeon. The group of Magic Knights split up and head to different parts of the castle, with Mimosa, Kirsch, and En heading to defend House Vermillion's section. Instead of directly fighting the elves, Mimosa locates and leads the humans out of the building, while her brother and En mask their locations and distract the elves. The three Royal Knights are surprised when Baval manages to locate them. Instead of attacking, the elf decides to talk, which confuses Mimosa, and tries to dissuade them from fighting. Mimosa refuses to give up, so Baval laughs and warns them about the attack on the king. After the Shadow Palace is summoned, Baval explains the elves' plan for their human hosts. Kirsch attacks the elf, but Baval's Dice Magic repels the swarm of petals and he runs off to the floating dungeon.

The three Royal Knights then fly over to the Black Bull base and try to warn them about the elves' plan, but Reve traps a section in her Glamour World while Patolli and Drowa dismantle the rest of the building. Mimosa, Kirsch, and En are then caught in Drowa and Eclat's Reflect Iris. The spell disappears once Asta defeats the elves. After Asta exorcises the spirits, Mimosa begins healing Asta. She gets flustered when Sally hugs Asta and reveals that he promised his body to her.

A pair of elves attack the group, but Fuegoleon and Mereoleona save the Magic Knights. When Magna points out that the gate to the Shadow Palace is shrinking, Mimosa warns everyone about the consequences of the completed reincarnation. While Kirsch and the Black Bulls remain to hold off a group of possessed Golden Dawns, Mimosa goes with Fuegoleon and Mereoleona, while Nozel carries Asta and Noelle.

Once they pass through the gate, the group is separated and scattered to different parts of the palace, and Mimosa lands on top of Asta. She heals him as an apology and then maps the palace, locating the humans and elves. They decide to enter the room above them and encounter Lira. Mimosa panics as the elf attacks them with all of his illustrations. The paintings begin to overwhelm them so Mimosa ties herself to Asta's back and heals him as he continues to fight.

Mimosa and Asta are surprised when Charmy Pappitson drops into the room. After Charmy fails to placate Lira with food, Mimosa watches as the elf knocks Charmy down. Mimosa then senses a change in Charmy's magic, and Lira reveals that Charmy is half-dwarf. Mimosa and Asta watch as Charmy's sheep turns into a wolf and consumes Lira's paintings. Mimosa and Asta leave Charmy to fight Lira on her own, and head into another room.

The pair find Baval laying unconscious, and Mimosa senses magic there that is not a human's or elf's, which puzzles her. She creates a Magic Flower Guidepost and locates Yuno with three others in a newly forming room. Mimosa and Asta drop into the room, and Mimosa is confused and disturbed by Zagred.

After Nozel defeats Patolli, Mimosa begins healing Rhya despite him being an enemy. Zagred's magic pours down from the room above, and Asta throws Mimosa and Rhya to safety. Mimosa is relieved when Asta emerges unscathed. She uses her Magic Flower Guidepost to discover that the devil's magic is flooding the other rooms, so Nozel and Mimosa head out to save the others, while Asta, Yuno, and Patolli head up to Zagred.

As they are flying through the corridors, Mimosa and Nozel are surprised when Licht draws on Rhya's and Ronne's magic to help power a spell to destroy Zagred. When Mimosa and Nozel reach Noelle's location, the devil's magic begins pouring down from above. Licht and Lemiel Silvamillion Clover send out protective auras to the elves. Mimosa wonders from whom the magic is coming, and Rhya explains it is from the human prince. Fana leads the group up toward the topmost chamber, and when the protective light disappears, Valtos saves the Magic Knights and elves and warps them up to the topmost chamber.

The humans and elves return to Clover Castle, and Mimosa watches as William and Licht combine their magic to connect the elves to a giant tree through which Asta sends Anti Magic. Afterward, on top of a broken tower, Mimosa heals Asta while Noelle, Secre, and Lemiel stand nearby. Mimosa recognizes that Lemiel looks like the statue of the first Wizard King, and Asta explains that it is indeed him. As Lemiel's body begins breaking, Mimosa is unable to help with her Healing Magic. The group somberly watch the prince crumble away.

Later that day, Mimosa attends a meeting with Julius. He lists and explains his predictions for the kingdom's future. When Julius brings up that the Magic Parliament might use Asta as a scapegoat, Mimosa and Noelle share concerned looks.

A few days later, Mimosa, Klaus, and Hamon read the newspaper article about Asta's trial and she remembers that Damnatio Kira once coldly judged his own father. After receiving a mission to investigate devils, the Black Bulls discover a powerful curse in the Heart Kingdom, so Asta and Noelle visit Mimosa to ask her about her trip there as a student. Mimosa notes that the application period is still open, so she secures passage for the three of them and Finral into the Heart Kingdom.

They travel by boat, and after passing through the barrier, they are greeted by Gadjah, whom Mimosa remembers from her previous visit. He hands them crimson orange juice and tells them the history of the Heart Kingdom while the Princess uses her Water Magic to move the boat across the kingdom. Mimosa looks at how peaceful the country looks and thinks to herself that it is unbelievable that a devil is there. Suddenly water traps Asta in a ball and whisks him away. Mimosa questions Gadjah's motive, to which he replies that it is for the sake of peace.

The three Magic Knights chase after Asta, jumping off the boat and being teleported forward by Finral's magic. However, Gadjah catches up to them. After seeing Gadjah bend his lightning bolt spell, Mimosa recognizes that he is using Mana Method. Finral creates a portal to send the lightning elsewhere, while Mimosa shoots at Gadjah with Magic Cannon Flower. Gadjah then draws a magic circle in the sky, much to Mimosa's confusion. The Magic Knights escape the resulting lightning strike. Mimosa's Magic Flower Guidepost is then used to accurately open a portal behind a Gadjah so Noelle can hit him with Sea Dragon's Roar. Gadjah survives the spell and speeds over to the three, catching them off guard. Instead of attacking, he kneels and apologizes for testing them.

Gadjah then escorts them to the Royal Palace, where they are reunited with Asta and Secre. Mimosa is shocked at the beauty and magic power of Princess Lolopechka. The Princess requests the Clover Kingdom's aid in stopping the devils. Asta calls Yami Sukehiro for permission, but the captain is too busy on the toilet. Mimosa pulls out a magic tool that connects to Marx Francois and sets up a meeting with Julius. Mimosa and the others listen as Lolopechka and Julius discuss an alliance between the Heart and Clover Kingdoms. Once an agreement is reached, Lolopechka offers to have the five Zero Stage-ranked Spirit Guardians train Mimosa and the others.

Mimosa, Noelle, and Secre are trained by Lolopechka, who focuses on the plans and tactics she developed after facing Vanica Zogratis and Megicula.

Six months later, Lolopechka sends Mimosa, Noelle, and Finral to follow after Asta who left to stop one of the Spade Kingdom's mobile fortresses. Noelle carries the other two in a Sea Dragon's Cradle while she flies through the Grand Magic Zone. Noelle drops them in the broken fortress, and the two royals land gracefully. Mimosa heals the room of people who had their magic forcefully extracted. After Tolon is liberated and its citizens are returned, the Magic Knights report back to Lolopechka.

Afterward, Mimosa agrees with Noelle's idea of taking a bath, and Undine encourages Lolopechka to join them. At Elmora Lake, the three royal women are bathing. Mimosa is embarrassed when Lolopechka talks about and touches Mimosa's bust. Lolopechka then thanks the two of them for being such good friends.

Sometime later, Mimosa and Noelle are in the Princess's underground chamber and watch Lolopechka pamper Charmy. Mimosa notes that both Lolopechka and Charmy are problem children. The cheery atmosphere is abruptly halted when Lolopechka senses the infiltration of Vanica and her five Dark Disciples. Mimosa and Noelle remain with Lolopechka while the others are dispatched to fight the Dark Disciples.

Mimosa celebrates when most of the Dark Disciples are defeated. However, Robero Ringert breaks into the underground chamber. Having anticipated his arrival, Mimosa easily defeats him with the support of Undine. Vanica then enters the room, which causes Mimosa to panic. When Robero stands back up uninjured, Mimosa is confused, and Vanica demonstrates and explains her curse as the other Disciples across the country stand back up. Mimosa, Noelle, and Lolopechka resolve to defeat Vanica.

Robero wraps his tongue around Mimosa, but she protects herself with plants and activates the Control Magic Grass seed that she slipped into her previous attack. She decides to take on Robero herself, leaving Noelle and Lolopechka to handle Vanica. Robero tries to convince Mimosa to give up, but she refuses because she wishes to protect her friend Lolopechka. During the fight, Vanica decides to abduct Lolopechka and, as she flies away, detonates the devil power in her Disciples. Mimosa watches as Robero's body swells due to the building magic power before he becomes a massive explosion. Mimosa and Noelle manage to block some of the explosion. The Magic Knights are later found by Patolli, Rhya, Vetto, and Fana, who take them back to a secret village of elves, Elysia.

When Noelle pleads with Patolli to train them, Mimosa and the others echo her resolve to become stronger, and Patolli agrees to teach them the elves' Ultimate Magic. Patolli takes them to meet Dryad, who trains them to attain Ultimate Magic.

Three days later, Mimosa and the others travel to the Spade Kingdom's capital in order to help stop the Qliphoth Advent Ritual. They use True Magic attacks to decimate the horde of low-ranking devils.

Later, at Luck's suggestion, Nacht Faust brings Mimosa to Vanica's chamber. After Megicula's defeat, Mimosa arrives and uses her Ultimate Magic, Flower Princess Utopia, to heal Gadjah's, Rill Boismortier's, and Charlotte Roselei's fatal injuries. Afterward, Gadjah confesses his love for Lolopechka, which shocks Mimosa. She later heals Nacht's injuries while they watch Zenon Zogratis's tower crumble, revealing that Yuno has won.

After the second gate opens, Lucifero combines the bodies of all the devils into one giant, monstrous form. Asta cuts the monster in two, destroying the coffins holding William and Yami. As half of the monster falls toward the castle town, Mimosa heals Yuno so that he can fire a Spirit of Euros. The arrow destroys the upper portion, saving the citizens and Magic Knights below. However, Lucifero compresses the monster's remains into a body, through which he manifests in a half-complete form. He then forces the humans to prostrate themselves before him. Yuno uses his Star Magic to shield himself and Mimosa from Lucifero's gravity and then teleports Asta to them before the devil can kill the Black Bull. When Lucifero attacks them, Yuno teleports Mimosa and Asta away from the battlefield. Although she does not want Asta to go back into battle, Mimosa begins healing and has to tell Sekke Bronzazza to be quiet so she can concentrate. Even though she runs out of magic before healing him completely, Asta stands back up and walks toward the fight. She tries to talk him out of it, but her words cannot get through to him.

After Asta defeats Lucifero, Yuno teleports Mimosa over to Yami and Nacht, who are dying from the holes in their torsos. However, Mimosa's magic power has not recovered and she is unable to heal them. When Charlotte confesses her love for Yami, Rouge pulls the Black Bulls out of the rubble of their base, and Charmy force feeds Mimosa some of her Master Chef's food. With her magic power restored, Mimosa saves Yami and Nacht and then heals Asta.

A year and three months later, Mimosa attends the special awards ceremony for Asta. At the banquet afterward, Mimosa and Noelle are flustered over their feelings for Asta, so Secre whispers to them that Asta is going to be confessing his love, which further flusters the pair, much to Secre's entertainment. The three women spy on Asta as he takes Sister Lily out onto a balcony and proposes one final time, which shocks Mimosa and Noelle. They listen as Lily refuses because she views Asta as a brother. They are all surprised by the sudden arrival of Lucius Zogratis and initially confuse him for Julius. Lucius then stops time for everyone, so when Asta nullifies the Time Magic spell, Mimosa and the others are perplexed by the sudden change in events and Asta's declaration to surpass the Wizard King.

Once Asta takes the fight further into the city, Noelle and Secre fly after him, with Noelle pulling Mimosa along with them. Upon seeing Asta heavily injured, Noelle attacks Lucius and Lily, but Lily blocks Noelle's attack. Mimosa and Secre head toward Asta to heal him, but Lily teleports in front of them and traps Mimosa, Noelle, and Secre within a spatial cube, disrupting their spells and preventing them from escaping. Lily then teleports Asta away, horrifying Mimosa, Noelle, and Secre. As the Magic Knight Captains arrive, Lucius and Lily teleport away, and the spatial cube around the three women dissolves.

Asta
When Mimosa first met Asta, she did not pick on him or think badly of him as Klaus did. She found him to be interesting due to his lack of magic power. However, after Asta saved her from Mars, she began to develop strong romantic feelings for him. She tells Noelle she liked him because of his determination, body and personality. Mimosa planned to get stronger so she could be able to stand side by side with Asta, using him as her motivation.

Before arriving in the Heart Kingdom in the anime, Mimosa felt a little irritated when Noelle used her water magic to wash down Asta's throat from eating one of her sandwiches.

Kirsch
Kirsch Vermillion is Mimosa's older brother and the vice-captain of Coral Peacock. She shows a clear disdain for her brother, going as far as even telling him how he disgusts her with his obsession with beauty.

Noelle
Noelle Silva is Mimosa's cousin and also childhood friend. She has deep respect for Noelle and treats her better than the other members of House Silva. The source of this admiration comes from Mimosa aware of how hard Noelle works since childhood. Mimosa often expresses her concerns over Noelle because of how often Noelle was ridiculed by nobles and her siblings. When, Nozel complimented Noelle and asked her for her help, Mimosa smiled and was happy for Noelle.

They both expressed concerns for Asta as they both have romantic feelings for him and admire his determination. When Mimosa told these feelings to Noelle, it left them both anxious over the matter.
