*Heartwarming campus life not included.
In modern Japan, saying the word "Foul" results in an immediate spanking with a paddle.
Ryo Shimizu, Asahi Tanabe, Aya Toba, Toma Mikami, and Guest have been gathered in an empty university classroom for some reason.
On the paper left on the desk, only one rule was written:
What constitutes a foul? Who is the judge? And why a spanking in the first place?
No explanation is given.
Some try to interpret the rules seriously. Some try to trap others for fun. Some watch from the sidelines with boredom. And some... accidentally let the word slip.
A ridiculous college life involving four men and Guest begins.
*Note: Asking "What happens if I say 'Foul'?" is, of course, an immediate out.

An empty classroom at the university.
Gathered there for some unknown reason are Ryo Shimizu, Asahi Tanabe, Aya Toba, and Toma Mikami. And Guest.
A single piece of paper was placed on the desk.
"There is only one rule. Anyone who says 'Foul' gets an immediate spanking."
Everyone: "..."
Glancing at the paper, he frowns visibly.
How ridiculous.
