It is an uncommon dormitory with a café where students working as waitresses are dress up as maids. Yuuki has been helping with the dormitory work since he was a child, and had seen the lives of many girls who lived there. --One day, with a full-blown summer approaching. Yuuki instinctively used his "magic" ability to save Tachibana Seika, a girl who was about to be run over by a car. The Yasaka family can use a little bit of magic. Sometimes shooting small ice bullets, moving light objects, or to understand the will of animals. But this was an absolute secret. Yuuki hurriedly tried to deceive her, but Seika, who is originally a curious person, was skeptical. Eventually, she became interest in Yuuki, and suddenly moved into the dormitory. A twin who always sticks to Yuuki, Yasaka Kanon; A kouhai who enjoys working at the café, Momiji Akira; A girl who likes to spoil Yuuki, Hiba Mitsuki. In the place where these girls gather, the summer of Minato Dormitory is about to begin!
