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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

The next day, the recital chamber was filled with muted tension. Candles lined the stage, their flames flickering like heartbeat signals.


Haru Minazuki stepped forward first, flute trembling in hand. Emerald light radiated from her as she played, soft and sorrowful, the kind of melody that made listeners feel both hope and despair at the same time.


Tsubasa Kuroe followed, cello singing deep and commanding. The gold aura of pride enveloped him, and every note shook the chamber with authority.


Ren waited, hands clenched on his violin. When it was his turn, he walked to the stage and faced the empty seats. The auditorium seemed too vast, too silent, too alive.


Crimson notes erupted, echoing like a heartbeat in the chamber. Auri's melody intertwined with his own—he could see it in the shadows, in the flicker of candlelight, in the faint glow of Ema's aura.


The final note lingered longer than natural. Then… silence.


Murasame's voice broke the quiet. "Crimson… powerful, but dangerous. Your passion leaves a scar in the walls. Remember it. Do not waste it."


Ren stepped down, heart pounding. He realized: in this academy, every performance was a test—and every note was a risk of losing something irretrievable.
