Everyone strives to fulfill a dream, including the musically gifted Kanon Shibuya. Kanon, however, is unable to enroll in Yuigaoka Girls' High School's music program due to her stage phobia and instead enrolls in the regular curriculum. Despite Kanon's conscious determination to completely stop listening to music, Tang Keke, a student, rekindles Kanon's passion for music with her own: a fondness for school idols. Ren Hazuki, the director's daughter at the school, strongly opposes Keke and Kanon's attempt to join a school idol group. However, when the girls approach the director shortly after, she agrees to let them start a school idol club as long as they place first at the Yoyogi School Idol competition.
