Wakana Sakai stopped singing after her mother died, and she has kept her distance from music ever since. Konatsu Miyamoto, who has left the school choir club, sets up a club of her own and pulls Wakana back in alongside jockey hopeful Sawa Okita and Taichi Tanaka, the badminton club's only member. Wien, a boy just back from twelve years in Austria, makes five, and the group rehearses toward the school festival with each of them carrying a reason to perform once more before graduating. This manga adapts the anime of the same name.
