Prison school is one the dumbest Manga I've EVER read. It's also extremely funny.

So these 5 boys go to all girls school and then since they become known as peeping toms go into a prison created by the girls. This prison for them is guarded by sexy women who beat the shit out of them whenever they say or do something bad. This first volume really focuses on our main characters trying to adjust to school life, go out on a date, and escape from the prison.

This is so stupid. The story makes no sense. It would never happen.

We got that out of the way, right? Now talking about the humor. It's really funny. From physical humor to great dialogue. All the characters are over the top but really entertaining. Also the art is great, and of course if like Fan Service, you're about to see a ton of ass and tits.

Dumb as hell? Oh yes, very much so. Funny and entertaining throughout? Oh yes, very much so. A 4 out of 5.
