A world where art transforms into magic. People that can create enthusiasm with their Magic Arts are known as Artistas in this realm, and they work in show business. A mysterious new student called Kohana Aigasaki transfers into Hoshinomori Private Magical Arts High School, where Artistas are educated. Kohana gets appointed to the Hoshinomori Summer Festa cultural event organizing committee at her school. She spends her amorous school life with six other lads who aspire to be performers. Each of the lads is an expert in his particular Art, and they all want Hoshi Fes to be a success. Furthermore, the lads hope to be picked with Kohana as the school's Artista Prince and Princess, which is only done once a year.
