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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

Rei Kanzaki remained silent, perched near a shadowed wall, her dark hair spilling over her shoulders. She hadn't spoken since arrival, yet her aura pulsed a deep blue—regret, sorrow, and something older.


Ren approached cautiously. "Why… don't you sing?"


Her eyes opened, icy yet haunting. "I can't. Once, I performed for an audience. They heard my voice… and lost something vital. Music should not destroy. Not like that."


He shivered. "The academy… it doesn't just listen. It takes. It… it will demand something from all of us."


Rei's gaze softened faintly. "Then you must play carefully, Hayami. Some melodies… cannot be returned once released."


Her warning lingered in his mind as he returned to the broken bow and the incomplete Scarlet Strings. He began to understand Rei's pain, and why some music could carry the dead along with it.
