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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

Hours passed. Sweat, tears, and exhaustion weighed down the prodigies, yet the final measures of Scarlet Strings began to form. Threads of color—crimson, silver, blue, green, violet—coiled together, glowing brighter than ever before.


The spirit of the melody seemed to smile, releasing faint harmonics that echoed through the chamber like wind through a cathedral.


Ren felt Airi's presence more vividly than ever. The crimson thread pulsed steadily, no longer a warning, but a lifeline.


The final note rang out. Silence followed—a perfect, fragile stillness.


And then, faint applause echoed from nowhere. Not from the living, but from the walls, the shadows, and the souls who had waited decades for someone to finish the melody.


The first completion of Scarlet Strings had been achieved… and the academy watched, curious, calculating, and hungry for the next act.
