A world where art becomes magic. In this world, people who can inspire passion with their Magic Arts are called Artistas, and they work in show business. At Hoshinomori Private Magical Arts High School, where Artistas are trained, a strange new student named Kohana Aigasaki transfers in. Kohana is assigned to the planning committee for the school's annual Hoshinomori Summer Festa cultural festival. She spends her romantic school life with six other boys who aspire to become entertainers in the future. Each of the boys specializes in his own Arts, and they aim to make Hoshi Fes a success. Additionally, the boys also aim to be selected alongside Kohana as the school's Artista Prince and Princess, a title chosen only once a year.
