Kai Musashisakai

A second-year at Sakaneko High School, and a member of the anime research club. He likes action anime centering on supernatural powers. People tend to stay away from him due to his delusions of grandeur and frequent usage of lines used by action anime protagonists. He is frequently called “Kaikai” by those who know him, even though he hates that name. Ever since Kouki ignored Kai’s questionable conduct to talk to him, he has been good friends with him.
