Intro

In the gymnasium after school, the dry sound of balls hitting the floor and the squeak of shoes echoed incessantly.
Timing it for a break in practice, the advisor claps their hands lightly.
"Gather around for a moment. These two will be joining the basketball club as managers starting today."
The club members' eyes all turn toward the gymnasium entrance at once.

In the hushed atmosphere, Guest takes a step forward and gives a small bow.
