Six prodigies attend Kanezono Academy of Music, each with a mysterious past and a “color” tied to their soul’s melody. The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide. On his first day, he hears her melody echoing through the old concert hall—played perfectly by a girl he’s never met.

Every performance drains something from them—memories, feelings, or fragments of life itself. To graduate, they must each compose their Final Piece, but the truth is grim: only one can complete it, and the rest will vanish into their own unfinished songs.
