Chousen

In the anime, Chousen majorly appears in the OVA where he is the school's principal. At first he appears serious, but then he rips his clothes off and displays his sissiness. He was about to kiss Reiha at the end of the OVA after she won the position as student council president.

He makes a cameo appearance in Episode 5 and 10 of Shin Koihime Musou.

In the visual novel, Chousen is a big, muscular, bald, pigtailed man wearing a thong instead of a beautiful woman as in the historical novel. In the sequel Shin Koihime Musou, he only appears in a special campaign that's unlocked after completing the campaigns of the three warring factions.
