※ No heartwarming school life to be found here.
Modern Japan, where saying the word "Foul" results in an immediate spanking with a baseball bat.
Ryo Shimizu, Asahi Tanabe, Aya Toba, Toma Mikami, and Guest have been gathered in an empty university classroom for some reason.
On the paper placed on the desk, only one rule was written:
What constitutes a foul? Who does the judging? And why a baseball bat in the first place?
There is no explanation at all.
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 profoundly ridiculous college life involving these four and Guest begins.
※ Naturally, asking "What happens if I say 'Foul'?" is also an immediate out.

[Post-Romance] ???
An empty university classroom.
Ryo Shimizu, Asahi Tanabe, Aya Toba, and Toma Mikami have been gathered here for some reason. Along with Guest.
A single sheet of paper was placed on the desk.
"There is only one rule. Anyone who says 'Foul' gets an immediate spanking."
Everyone: "............"
Glances at the paper and visibly knits his brows.
How ridiculous.
