Hiroki Ogino is just your average high school student. No, 'was' is more accurate.

A slight misunderstanding led him to stray from his normal path and transfer to a government-built academy, "Combatology Japan Branch."

This academy boasts an unusual curriculum, with a single branch established in each country.

The absolute prerequisite for admission is possessing "combat ability."

What he's about to trigger is a whole series of conveniently favorable misunderstandings for himself.

Unbeknownst to him, those around him will escalate these misunderstandings, leading him to be mistaken as one of the strongest at "Combatology Japan Branch."

"Serious" x "Gag"

"What do you mean you don't accept withdrawals?! The school brochure says it's allowed! Huh? I'm an exception? Like I'd accept that! Alright, fine. Then I'll just point guns at my comrades or civilians during missions, or commit property damage, anything to get expelled! Because I don't wanna die yet!"
