Middle-school first-year student Hibino Matsuri loves festivals, and she dreams of one day being able to star in "PriMagi", a magic-like form of stage entertainment borne from song, dance and fashion. That day arrives when the hyper-spirited, trouble-making magician Myamu arrives from the magical realm and scouts Matsuri for PriMagi. Together, the two compete with rivals to rise to the top of PriMagi.
