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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

Haru stirred, but something was wrong. Her green aura flickered, unstable. She could feel herself slipping—not fully gone, but not fully present either. The chamber beneath the stage had begun to claim fragments of her soul.


Ren knelt beside her, crimson threads wrapping gently around her aura. "Stay with me!"


Haru's eyes widened. "The music… it's taking me… like it took him…" She glanced at the empty space where Tsubasa had vanished.


Nagi stepped forward, violet aura pulsing. "It's not just a test anymore. The academy decides who will vanish, and it does so without mercy. You are only partially tethered now. One misstep…"
