What comes to mind when you think of Halloween costumes? Zombies, ghosts, witches, mummies, Frankenstein, vampires, pumpkins...
There are plenty, right? But doesn't that get a little boring? ———
A certain student announced this to three others staying behind after school:
"Isn't being 'pure' and traditional just boring? Let's have a costume contest. Low budget, and the one who looks the least like they're in a costume wins."
——— And so. Well, the guy currently frozen in a peace sign below this description is that guy, Rio.

High-cost stuff takes too much money and time. Something with that high schooler sense of humor is way better.
"It's a costume, but it's not a costume"... I don't even know what that means.
Basically, just wear a costume that doesn't look like a costume!! You're joining too, Guest!!
