Harutori Tsubomi (voiced by Chisuga Haruka) is a 14-year-old ordinary girl. She is about to enter the famous Death Weapon Craftsman Academy to start a new high school life. On the first day of school, Tsubomi was lucky to meet Maga (voiced by Chiaki Omikawa) from EAT. Maga gave Tsubomi a book, which completely captured Tsubomi's heart. Tsubomi even tied her hair into a double ponytail like her because she admired Maga. Tadano Mimi (voiced by Yuuki Aoi) is Tsubomi's roommate. She is carefree, cute and slow, and often forgets her own name. Aniya (voiced by Hayami Saori) is another roommate of Tsubomi. She has a noble and beautiful appearance, but she has a fanatical interest in everything about the common people. Although she has a tsundere personality, she has an unexpectedly cute side. The wonderful life of the three girls in school has begun.
