Suzunu Matsuri, a high school student with the appearance of an elementary school student, is invited by her senior Ayaka to join the handicraft club. However, the club's true form is a cosplay club!? What's more, the other members include a big-breasted manager whose hobby is cosplaying cute girls, an active female cosplayer who is an otaku, and a super masochistic boy. There are a lot of weirdos out there, including the vice manager and a male member who is forced by the manager to dress as a woman. Will Matsuri, who struggles with being bullied by the club members, be able to become a full-fledged cosplayer?
