--One day, with summer in full swing... Courage unleashed his ability "magic" on the spur of the moment, and he rescues a girl, Haruka Tachibana, who was almost run over by a car.

People from the Yasaka family can use a bit of magic. Sometimes they shoot out little ice bullets, sometimes they can move light objects, sometimes they can fetch the will of animals... But it was an absolute secret. Yuuki hurriedly misled her, but Haruka, who has always had a curious nature wondered about it. Eventually, she begins to take an interest in Yuuki and moreover, she suddenly joins the Minato dormitory.

The twin "Kanon Yasaka" who is always sticking around. Akira Momiji, a junior who works hard at the café. Mizuki Hiba, the woman who spoils Yuuki.
