Kou Mukami is the second son of the Mukami household. He is an idol in the human world as a side job. Kou is said to have a handsome, beautiful face. He has curly blond hair with his bangs covering the top right side of his face. He wears earrings on both ears.
He appears friendly, but he’s actually very selfish and two-faced. Anything surrounding this idol Do-S (extreme sadist) is always at his mercy. He uses his handsome, beautiful face to his own advantage.
