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

Appearance
The devil is a large, black figure with wings, horns, a tail and pointed teeth.

Personality
While most of its personality is unknown, it is shown to be very intimidating, such as how individuals shudder whenever they sense its presence.

It has shown a desire to possess Asta's body, but has failed when Asta refused it.

Its confrontation with another devil shows it to be rather disrespectful and sadistic. It mockingly refers to the other devil as its senior, while ridiculing that devil's loss with a sneer.

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.

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.

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