樋口 清太郎
from The Tatami Galaxy
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".

The Tatami Galaxy
The story revolves around an unnamed third-year Kyoto University student who reminisces about his early campus life. He meets Ozu whose encouragement sets him on a mission of dubious morality. He contemplates his affection for a younger female student, Akashi, and makes promises to her, usually of and within a romantic subtext. The culmination of his dubious missions often conflict with his interest in her in some way.
