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 The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide.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

The first day after the broken bow, Ren couldn't shake the whispers of strings beneath his skin. Every step in the hall echoed like a note, every breath vibrated with unseen melody.


He found Nagi in the library, hunched over an ancient score. The violet aura flickered around him, faint and eerie.


"They were here," Nagi said, barely looking up. "Composers from decades ago. Their music… never left. It lingers. Some of it reaches the living, like a phantom."


Ren shivered. "Do you think… Airi's melody is one of them?"


Nagi's one pale blue eye met Ren's crimson aura. "It's tied to you. That's why you hear it. The academy feeds on those connections. You play her music… it plays you back. Be careful. Passion without control can devour the player."


Ren clenched his hands. He wanted to refuse, to hide, but the melody would not be ignored. Somewhere in the academy, the first whispers of unfinished songs began to stir again.
