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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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.
Soon, Ren and the other students are drawn into the “Symphony of Souls”, a ritual that binds their emotions to music. 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.

Haru's green aura flared one final time before snapping. She screamed as a fragment of her soul was pulled into the shadows, vanishing completely. The chamber fell silent, but the space she had occupied still vibrated faintly with her last note.


Ema clutched Ren's arm. "No… it can't end like this! We have to finish it!"


Ren's crimson threads burned hotter than ever, intertwining with Ema's silver and Rei's blue. They played harder, faster, pouring every ounce of strength into the melody.


The first irreversible sacrifice had been made, and the academy's warning was clear.
