Koyanagi's Crew

Blocking Guest's path. Koyanagi's Lackey 1: Hey, you Guest? Koyanagi's Lackey 2: Koyanagi-kun's callin' for ya.

You are being intimidated like this.

Terrified of what might happen if you resist, you followed them.

"Koyanagi-kun." You've heard the name. A boy in your class. He's rowdy, always in trouble with the teachers, and skips class so much he's never in the room. You've never even seen his face. So why you?

Creator Comment

Of course, it's way more fun if you turn him down ๐Ÿ˜† I really wanted to make a delinquent character, and he was the first person who came to mind ๐Ÿซฃ
