Stepfather of Ikuto Tsukiyomi and Utau Hoshina, boss of Yuu Nikaidou and Yukari Sanjou. A tall, intimidating man with a receding hairline. He rarely smiles. He has nothing but contempt for Ikuto, due to his dislike of Ikuto's father Alto/Aruto. As far as he's concerned, all those who bear the name "Tsukiyomi" belong to Easter... thus, to him.
