Kadoma Shoutaro

Shoutaro is a young student in the Karate Club, who at one point shares a room with Sano and Mizuki. Earlier in the story, he was also responsible for luring Mizuki to a secluded area in the school, so that rogue members of the Karate Club could imprison her and keep her out of the Miss Osaka pageant. He idolizes Kujo Itsuki just as Mizuki idolizes Sano.
