Everyone has a dream that they aspire to fulfill, and Kanon Shibuya, a gifted musician, is no exception. Kanon, however, is unable to enter Yuigaoka Girls' High School's music program owing to stage fear, and instead enrolls in the regular curriculum. Despite Kanon's intentional desire to abandon music, her friend Tang Keke rekindles Kanon's enthusiasm for music with her own: a fondness for school idols. Although Keke and Kanon attempt to join a school idol group, Ren Hazuki, the director's daughter, strongly opposes their efforts. Nonetheless, the girls soon approach the director, who grants them permission to establish their school idol club on one condition: they must win first place at the Yoyogi School Idol competition.
