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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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 sat quietly in the shadows of the hidden chamber. For the first time, she lifted her hands to the air and hummed—a faint, trembling sound. The blue aura surrounding her shivered and stretched, resonating with the ghostly notes echoing from the piano.


Her eyes met his, filled with fear and sorrow. "I… I tried to stop. But the academy… it demands it. My voice… is tied to the melody."


When she sang a single note, the room responded. Portraits trembled, faint whispers rose in harmony, and crimson and silver threads intertwined with her blue aura. Ren realized that Rei's voice was a key—a dangerous one, but necessary for completing Scarlet Strings.


If we falter, her voice—and everything she represents—could be silenced forever.
