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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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 chamber was silent again. Shadows clung to corners, faintly vibrating with residual harmonics. Ren's bow hung in the air, crimson aura still pulsing.


Ema's silver threads intertwined with his crimson, a fragile tether keeping them grounded. "We can't stop now," she whispered. "It knows we're here."


Nagi's violet aura flared, casting a ghostly light across the portraits. "Every melody you play is a choice," he said. "Every note is a path. Some paths lead to salvation… others to oblivion."


Ren stared at Airi's portrait. "I'll finish it… I have to. No matter the cost."


The faint echoes of a violin began once more, calling them deeper into the academy's secret history.


The next stage of Kanezono Academy had begun. And none of them would leave unchanged.
