This is a wild school life comedy that jumps between the circumstances of various characters. One of these is Magaribuchi, a kid who punched his friend on a whim once... and the punching didn't stop until he was the boss delinquent of the school. His tough-guy persona is severely threatened by his first encounter with 'Moe' art. Another is the 27-year-old single teacher, Akemi. Years ago, she was a magic girl, fighting to defend her elementary school from monsters. Now, she tries to do the best she can with what she has left. There's also the three soldiers of 'earthly pleasures' whose 'power' is bound up in their particular vice (lust and sloth, for instance). These and many more characters, like the cyborg teacher, go through the crazy adventure that is their everyday school life.
