The devil is a large black figure with wings, horns, a tail, and pointed teeth.
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 be sadistic, if not disrespectful, as it mockingly refers the other devil as its senior while also ridiculing the devil's lost with a sneer.
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.
