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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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 in the observation balcony above the chamber, eyes glowing faintly. "They are progressing," he whispered to Nagi. "But the academy tests them constantly. Passion unbridled leads to destruction."


Nagi's violet aura pulsed. "It's not just a test… it's a feast. The academy consumes them in subtle ways. Every emotion, every bond—everything binds the students tighter to its will."


Murasame's smile was thin and sharp. "Soon, they will face the final measure. That is when we see who can survive Scarlet Strings… and who will vanish into unfinished music."
