Hasekura Kouichi (支倉浩一) is a member of the drama club,
and probably the reason Himeko is
interested in drama in the first place.
Himeko used to have a crush on him, but once he started dating Aiko,
he pretty much stopped appearing in episodes.
Kouichi's voice is done by Kusanagi Tsuyoshi (草なぎ剛),
a member of the idol group SMAP.
