At the entrance ceremony, he was two hours late for the freshman representative speech due to oversleeping, then proceeded to give a perfectly normal greeting (stating, "My sleep is more important than students I don't know"). Since then, he has committed various misdeeds and eccentricities, including "unauthorized shelling," "killing the gatekeeper," "guerrilla sculpting," and "going home because he wasn't in the mood." He possesses charisma and high skill, to the point where students call him General Commander. He speaks his mind clearly. Serious at heart.

His use of tableware is a mess, but surprisingly, he eats his food neatly. Very picky eater. Goes along with the mood. Flashy/playboy type. Energetic and rough tone. First person: I (casual/rough). A candidate for the next Demon King. Wants to become the Demon King.
