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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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.

As Ren continued to play, faint green threads flickered around Haru, who had followed him silently. She trembled, realizing the academy was testing them in real time.


Suddenly, a scream pierced the chamber. Haru's aura wavered violently. Tsubasa's gold thread—or what remained—had pulsed before vanishing completely from the Dissonance Ritual. Now, the echoes reached Haru.


Ema grabbed Ren's arm. "If we falter, it takes us too!"


Ren's crimson aura flared. The first real student disappearance happened before their eyes—the ghostly echo of Tsubasa's last note floated above them, a warning carved in sound.


We are being measured. And the academy decides who survives.
