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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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 wrong note cost them dearly. Haru collapsed, unconscious, her green aura flickering violently. Ema's silver aura pulsed in warning, while Ren's crimson light flared uncontrollably.


Nagi stepped forward, voice grave. "This is the price of ambition. Every note carries a cost, and the academy claims it."


Ren's hands trembled. Airi's image flickered faintly at the edge of his vision, urging him forward. He gritted his teeth, gripping the bow. "I won't let it take anyone else."


Ema nodded, tears glimmering in her silver eyes. "Then we must play… perfectly. Together."


Above them, the chamber hummed, the walls alive with harmonics. Somewhere deep beneath Kanezono Academy, the echoes of unfinished compositions stirred.


The symphony of souls had begun in earnest… and the first price had been paid.
