Kai Musashisakai

Kai Musashisakai is a second-year Sakaneko High School student and anime research club member who likes supernatural action anime. His grandiose behavior and habit of quoting action protagonists can put people off, and acquaintances call him "Kaikai" despite his dislike of the nickname. He became good friends with Kouki after Kouki simply talked to him without being deterred by his behavior.
