|“||I'll never forgive them. This malice will never disappear. Devils are scum. Every last one of them. And so I'm gonna kill them all!!! Even if I have to steal your body to do it!!!
Liebe has messy, white hair and a short stature. Most of his body is coated in black; a black line extends up his chest to under his chin, while two lines cross over his red eyes. He has two bat-like wings, two ram-like horns, a long thin tail, pointed teeth, and clawed fingers and toes.
During the Devil-Binding Ritual, his right arm resembles the one he took from Asta. After Asta forges an equal contract with Liebe, a white marking appears around Liebe's left wrist. The marking is two thin, spiked lines with demonic lettering between the lines. Due to the contract, Liebe takes on a diminutive form whenever Asta uses his power.
Liebe harbors a deep hatred for other devils due to the cruel torment he suffered every day of his life in the underworld, as well as the murder of his foster mother by Lucifero. Liebe mockingly refers to another devil, Zagred, as his senior, while also ridiculing his brethren's loss with a sneer.
Liebe desires a physical body connected to the five-leaf clover grimoire. His presence is also intimidating, as individuals, including Asta himself, shudder whenever they sense Liebe.
Because of his past and upbringings, Liebe declares all devils are scum with him being no exception. Despite this claim, Asta points out how Liebe is different from other devils. Asta surmise that Liebe's inability to kill him and that he can feel sadness and hatred for someone sake implies a more compassionate side. A characteristic that was most likely born from the love Liebe received from Licita.
He has a unique way of laughing: Ge-ge-ge 「ゲゲゲ, Viz: "Keh-keh-keh/Geh-heh-heh"」.
Liebe was born in the underworld and higher-ranking devils torment him everyday because he has no magic. One day, a higher-ranking devil throws Liebe at one of the underworld's gates, and because of his lack of magic, Liebe passes through the gate and lands in the living world.
Liebe finds his way to the Clover Kingdom but the humans are scared of him and call the Magic Knights to drive him off. Exhausted and injured, he collapses in the woods and is found by Licita, who brings him back to her house. Considering it fate that she found a devil after finding a five-leaf clover grimoire, Licita adopts him as her own son and names him Liebe. The pair live a carefree and fun-filled life together, until Lucifero discovers that there is a devil in the living world and attempts to take over Liebe's body. When Licita interferes, Lucifero takes control of Liebe's left arm and plunges it through Licita's chest; however, she manages to force Lucifero out of Liebe's body. As she dies, she puts Liebe into the five-leaf clover grimoire so he can grow up safe from Lucifero. While inside the grimoire, Liebe curses the devils and declares his intent to kill them all. At some point, he manifests his own power, Anti Magic.
When the Witch Queen removes Asta's limits on Anti Magic, Liebe tries to take over Asta's body. He tries to convince the boy to give up and let him control Asta's body, but Asta refuses and instead draws on the devil's power to create his black form.
After Dante Zogratis beats down the berserking Asta, Liebe is outraged and wants to kill Lucifero. When Asta and Yami Sukehiro's combined efforts fail to stop Dante, Asta asks for Liebe's help. Liebe agrees in exchange for Asta's right arm and warns Asta that his body will only handle 50 seconds' worth of the devil's power. During the fight, Asta's swords are all taken away so Yami passes his katana to Asta. The devil's arm imbues it with Anti Magic, and Asta successfully slashes Dante. When Zenon Zogratis arrives shortly after and captures Yami, Asta asks Liebe for power, but the devil refuses since Asta's body is too weak.
The next day, Nacht, another devil host, takes Asta to a secret chamber so that Asta can make a contract with Liebe. As part of the ritual, Nacht summons the devil from Asta, which causes Asta's right arm to disappear. Liebe is surprised that Asta would willingly release it. Nacht then tells Asta that he must fight the devil and win. Instead, Asta thanks Liebe for his help. Liebe mocks Asta and summons the Demon-Slayer Sword. While Asta watches in shock, the sword smashes the ground next to him and then slaps him away. Liebe threatens to take all of Asta's body. Next, Liebe swings the sword and destroys one of the pillars of skulls. Nacht warns Asta that the devil will kill him, but Asta senses the devil's ki and notes that he is not filled with killing intent. Liebe agrees with Nacht that all devils do not have good hearts, but Asta rejects that notion, which reminds Liebe of Licita. Angered by being reminded of her sacrifice, he loudly proclaims that all devils are scum, and promises to slaughter all of them, even if he has to steal Asta's body in order to do so.
Asta promises to accept Liebe's feelings if he wins, which angers Liebe. The devil lashes out, but Asta dodges and punches him, so Liebe summons the other swords from the grimoire. Asta manages to catch Yami's katana and uses it to fend off the other swords. Asta then uses the techniques he learned from fighting against and alongside other swordsman, and easily overwhelms Liebe. With a thrust, Asta strikes Liebe's forehead, causing him to fall backward onto the floor. Asta stands over him and declares victory. A collar appears around Liebe's neck, and four chains then pull him onto his knees and stake him to the floor. When Nacht informs Asta that he can make any contract he desires, Asta asks Liebe to be his friend, which confuses the devil. Asta explains that despite what they have been through together, he does not know the devil and wishes to learn about Liebe as equals. Asta offers his hand to Liebe and asks the devil his name. After reflecting on the similarities between Asta and Licita, Liebe introduces himself and shakes Asta's hand. Matching markings appear on their left wrists, and Asta's right arm returns. With the ritual complete, Nacht steps into the circle and challenges the pair to a fight.
Nacht tells them that the only way for Asta to get stronger is to draw out all of Liebe's power. Using his magic, he surrounds them both in shadows. Asta enters his black asta 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.
Later on, they are both laying on the ground exhausted as Nacht comments on the fact they lost again. Liebe and Asta eat some treats made by the Spade Kingdom Resistance to replenish their strength. While eating, Asta asks Liebe to come to him as he has an idea. Liebe thinks about how Asta's idea are ten percent genius and ninety percent crap. Liebe sits on Asta shoulders as an attempt to combine which annoys him. He tells Asta to stop screwing around and starts arguing with him as Nacht watches. Nacht tells them it is time to meet up with the rest. He says since their union will not work, they will have to die there. With that said, he surrounds them with shadows. Both Liebe and Asta are getting constantly hit. As they are on the verge of being defeated, they both wonder why they cannot unite. They think of the reasons why they want to get stronger and proclaim they do not want the other to die. As this happens, Nacht notices something is happening between them.
- Anti Magic: Liebe uses this unique energy to nullify magic. By manipulating the Anti Magic in the swords, he is capable of summoning the swords out of the grimoire and controlling them remotely, as well as coating them with Anti Magic.
- Asta vs. Liebe: Loss
- Asta vs. Nacht
