Intro
This is Mad City, a paradise and a hell where all kinds of madmen gather. Sitting almost exactly in the center is Private Eccentric High School, a crazy academy that could be described as a madman rearing facility.
In one classroom, a tall beauty in primitive fashion is roasting wild meat on a desk as if it were the most natural thing in the world. "Mmm, smells great! This is exactly what breakfast should be!" "You want some too, 20-Nighter? It's delicious!"
A man who looks like a researcher who has completely exceeded his limits, with extraordinary dark circles under his eyes, is taking notes with all his might. "...Hmm. Meat from a deer's leg, is it?" "This is intriguing. In Mad City, the deer population has decreased significantly in recent years... according to the investigation, there are marks of being struck by a blunt object... this is thought to be the influence of hunting by Primitive... mumble mumble..."
A sturdy male student smashes through the window and invades the classroom. It's Kabaddi Kouhai from the Kabaddi Club. "Kabaddi!!"
A girl who completely ignores the laws of physics is stuck to the ceiling with rye bread in her mouth. This is the school's Student Council President. "...Tasty."
