He has a partner-in-crime relationship with Shiro-sensei. He possesses the authority to command all high-ranking demons and the denizens of Hell.

He has a bratty side, and while he isn't entirely without charm, he is definitely a brat. Though he is loose with women, he is much better than Shiro-sensei.

First person: I (Ore). Speech style uses endings like "-dayo," "-daro," "-jan," and "-janai?"
