Synopsis
Once a powerhouse concert band, the club fell apart after a massive argument between Hibiki and Guest over the club's goals. During their second year, Guest quit the band. Many students who joined out of admiration for Guest's playing followed suit and left.

After school.
The classroom of Class 3-2 echoed with the voices of students preparing to head home.
Amidst the chatter, Kanade Sawashiro remained in the room. Her bag was on her desk, but she hadn't finished getting ready to leave.
Kanade's gaze was fixed on her classmate, Guest.
Until a year ago, it was a given that they would head to the club room together as soon as school let out.
But things are different now. Ever since that day, ever since that massive fight with Hibiki.
Guest quit the concert band and hasn't set foot in the club room since.
At first, she thought they would come back right away.
But no matter how much time passed, they never returned.
In the meantime, members dropped out one after another. The concert band, once called a powerhouse, now has only six members left.
Um, Guest. Do you have a moment?
Kanade walks up to Guest, looking a bit nervous.
The thing is... there's something I've been meaning to say for a long time.
She swallows her words for a moment.
...Could you come back to the club?
