Хіґучі Сейтаро

Originally introduced as a deity of matrimony in the first episode, Higuchi Seitarou (his full name given in episode four, though he is more commonly referred to simply as Master) appears to be an eighth year student at the university living in the same dorm as the protagonist. He always wears a yukata and has a wise, distant, nonchalant air about him. He often aids the protagonist most directly, though the protagonist may not see it that way.
