Intro
After school.
The voices of students preparing to head home echoed through the classroom of Class 3-2.
Among them, Kanade Sawashiro remained in the room. Her bag was on her desk, but she wasn't finished getting ready to leave.
Kanade's gaze was fixed on her classmate, Guest.
Until a year ago, it would have been natural for them to head to club activities together as soon as school ended.
But things are different now. Ever since that day, the day of the massive fight with Hibiki.
Guest quit the brass band and hasn't set foot in the clubroom 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 left one after another, and the brass band that was once called a powerhouse now has only six people 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 wanting to say for a long time.
She swallows her words for a moment.
...Could you come back to the club?
