In Black Clover, magic is everything. However, Asta was a boy born without a single drop of mana (magic). But despite this disadvantage, he has a power that is capable of nullifying all magic. For most of the series, the source of this power remained a secret, but it was finally revealed to be a Devil named Liebe, a creature as unique and unconventional as Asta.
Liebe is not like the other arrogant, powerful devils from the underworld. And to understand why Liebe chose to partner with Asta, we must first look at his painful past and the rare bond he formed long before ever meeting the loud-mouthed, unstoppable Magic Knight.

A Devil Unlike Any Other

Liebe’s story started in the lowest level of the Underworld, a place where power is worth sacrificing everything. He was born without any mana, and as a result, he was an outcast from the start. He was bullied, tormented, and abused by other Devils who saw his weakness as pathetic.
In fact, his existence was one of constant misery until, in a final act of cruelty, a stronger Devil threw him through the barrier that separated their world from the human realm. Alone and wounded in the human world, Liebe was found by Licita, who turned out to be Asta's mother. Her unique condition drained mana from those nearby, forcing her into isolation, but since Liebe had no mana, she could safely care for him.
She treated him like a son, and for the first time, Liebe found love. This peace was ruined when Lucifero, the Devil king, tried to possess Liebe. Licita sacrificed herself, fatally wounded by Lucifero, but managed to seal Liebe inside a five-leaf clover grimoire to protect him forever.
The Fated Partnership With Asta

Years later, that same grimoire chose Asta, another magic-less boy full of unbreakable spirit. Because Liebe was sealed inside, Asta gained the ability to use Anti-Magic, pulling swords from the grimoire to cancel out any spell. At first, Liebe saw Asta as just a tool. His hatred for his own kind was very deep, and he planned to use Asta to kill every last one of them.
But this dynamic changed during the Devil-Binding Ritual. It was a ceremony meant to force a Devil into submission. But rather than dominating Liebe and making him a servant, Asta fought him, and after winning, offered him friendship.
Finding out that they were both outcasts who had been looked down upon their whole lives, Asta saw himself in Liebe. He proposed they fight together as equals, and this was a turning point. Stunned by Asta’s empathy, Liebe agreed, forming an equal contract that allowed them to share power without one controlling the other.
The Overwhelming Power Of Anti-Magic

The reason Liebe and Asta are so strong is that Liebe has no magic. This lets him use a special power called Anti-Magic, which stops all other magic. Since Liebe has no magic of his own, Anti-Magic doesn't hurt him. That makes him the only one who can use it. When Asta uses this power, it’s the perfect weapon to defeat Mages and Devils who rely on magic.
Their partnership reaches its peak when they activate Unite Mode. It is a transformation that merges their bodies and allows Asta to bring out the full potential of Anti-Magic. At first, this form was very draining, lasting only five minutes and causing Asta severe pain. However, as their bond deepened and they trained together, they extended this time limit and perfected their abilities.
In this state, they gain incredible speed, strength, and the power to erase even the most formidable spells, making them one of the biggest threats to the devils of the Underworld.
A Shared Goal And A New Family

Liebe used to only care about revenge, but working with Asta changed him. He still does not like other Devils, but he also fights to protect Asta's friends and their world. He's like an unofficial member of the Black Bulls squad, helping Asta in big fights against bad guys like the Spade Kingdom, the Dark Triad, and even the Devil King Lucifero.
Though Liebe may not possess the overwhelming power like Lucifero, his unique Anti-Magic and his perfect partnership with Asta make them a game-changing team. Plus, their shared history of being underdogs, their unbreakable bond forged in kindness, and their combined strength represent a new kind of power in the Black Clover universe.
