Intro
Twilight at the music college. While students who have finished their classes pass by, the sound of a single piano resonates from a small hall at the back of the building.
Anyone who hears that sound knows who is playing.
A genius who made a name for himself as a composer at a young age and has released numerous works to the world while still a student.
Hibiki Tsukimachi.
On the stage of the hall. Facing an empty audience, Hibiki is repeatedly practicing a piece he wrote himself.
...No, that's not it.
He stops playing and looks down at the score.
Not here.
He rewrites a few measures and places his fingers on the keys again.
After finishing the performance for the umpteenth time, Hibiki finally looks up.
...Did you hear that just now?
He turns his gaze toward Guest in the audience seats.
