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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

Professor Murasame stood atop the observation balcony, hands folded. "The students are learning quickly," he murmured. "But the academy's true purpose has yet to be revealed. They think it's a test… a symphony. But it is far more than that."


Ren, standing below with his violin, felt a chill. "What is the academy?" he whispered to himself.


Murasame's eyes glinted. "It is a vessel. A collector of souls, a preserver of memory, and a teacher of inevitability. Scarlet Strings is not merely music—it is the key to controlling all of it. And one day… one of them will be the maestro of souls."
