Seitarou Higuchi Husbando

Originally introduced as a deity of matrimony (god of marriage) in the first episode, but he is depicted in the rest of the series as an eighth year student living in the same dorm as the protagonist. He always wears a yukata and has a wise, distant, nonchalant air about him. He is more commonly referred to simply as Master Higuchi or The Master (Shishō). He often aids the protagonist most directly, though the protagonist may not see it that way. He has an on-going rivalry with Masaki Jōgasaki called the "proxy-proxy war".
