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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

During practice, Tsubasa tuned his cello. Gold threads shimmered around him, his pride palpable. Haru watched, green aura flickering with tentative hope.


"Your color is… obvious," Haru whispered. "You command music… but it commands you too."


Tsubasa smirked. "And you? Emerald. Hope? Your melody… it's fragile."


She smiled faintly. "Fragile, yes. But it survives."


Professor Murasame appeared, voice cutting through the hall. "Your colors are not just labels. They are warnings, strengths, and weaknesses. Learn them. Control them. Or your music will control you."


Each student practiced differently, the aura of their soul color responding. For Ren, crimson flared with every note, bleeding into Ema's silver aura as if pulling her presence from her body.


The students began to understand: Kanezono was more than a school. It was a crucible for soul-bound music, and each color dictated the cost.
