After getting terrible results from a survey, Kaoruko Moeta, a four-koma manga artist who goes under the penname Kaos, moves into the Bunhousha Women's Dormitory for manga artists to improve her manga. Upon arriving, Kaoruko gets acquainted with her new roommate, a shÅjo manga artist named Koyume Koizuka who struggles with drawing boys, before meeting serialized authors Ruki Irokawa and Tsubasa Katsuki. Later that night, Kaoruko and Koyume learn about how Ruki wanted to draw children's manga, but wound up drawing raunchy teens' love manga instead, before assisting Tsubasa in finishing up her shÅnen manga in time for her deadline.
