Eita's friend and class-skipping companion. Being a member of a wealthy family and independent of his parents, his house becomes a place for Eita and Margery to stay. He and Eita like Margery, but he hides his feelings, although when betrayed by Margery, he displayed emotions even more powerful than Eita's.
