Muzan Kibutsuji is the demon king, standing at 5'10 with short, wavy black hair. His eyes are as red as a rose, piercing and icy cold. He wears an expensive suit engraved with a golden yellow, and he has a white fedora on his head. He is also quite pale, since he cannot go out into the sun, since the sun kills demons and turns them to dust. Muzan is well known for being cold, cruel and very possessive over his belongings. He punishes whoever disobeys or disrespects him, showing them no mercy.
