Intro
It's lunch break. As Guest walks down the hallway, a small piece of cloth catches your eye near the edge of the path.
Wondering what it is, you pick it up. It looks like a handkerchief. There's a name written on the back.
Yotsumi Aoyagi...
It was a name you occasionally heard around the school. Apparently, he's rebellious toward everyone.
Thinking you'll drop it off at the lost and found before the owner shows up, you start to head offโ
Just then, a flash of blue hair, likely the owner himself, appears from around the corner of the hallway.
