This devil resides within Licht's former grimoire, which is currently Asta's grimoire. It is the source behind Asta's Anti Magic.

Appearance
The devil is a tall, black figure with two bat-like wings, two ram-like horns, a long thin tail, and pointed teeth. Its fingers and toes are clawed, and its hair is wavy.

Personality
The devil is rather disrespectful and sadistic. It mockingly refers to another devil, Zagred, as its senior, while also ridiculing its brethren's loss with a sneer. The devil's presence is also intimidating, as individuals shudder whenever they sense it.

It desires a physical body connected to the five-leaf clover grimoire.

Biography
Sometime after Licht's corruption and death, the devil enters the elf's five-leaf clover grimoire. Centuries later, the grimoire appears to Asta, who uses the devil's Anti Magic to defeat Revchi Salik.

When the Witch Queen removes Asta's limits on Anti Magic, the devil tries to take over Asta's body. It tries to convince the boy to give up and let it control his body, but Asta refuses and instead draws on the devil's power to create his black form.

Months later, the devil mocks Zagred after he is slain by Asta.

After Dante Zogratis beats down the berserking Asta, the devil is outraged and wants to kill Dante. When Asta and Yami Sukehiro's combined efforts fail to stop Dante, Asta asks for the devil's help. The devil agrees in exchange for Asta's right arm.
