A girl is sexually harassed by a teacher, there is nothing explicit but the man is stopped by another student.

On Episode 5, a man dissects a woman and her upper body and lower back can be seen briefly for a couple of secs, although it obscured by light.

A main female character has a rather large bust size. This is talked about throughout the series

In season one episode 15 there are some guys that beat some one up then one of the guys say whos next and the other one says the teacher that hits on students but it doesn't show anything and its not at all explicet really they only mention the teacher.

One or two shower scenes, brief upper Female nudity.

Some of the fights are a little bloody, but serious injuries tend not to occur.

Some strong language (which is more than the usual TV-14 show) in the dub, not a lot in the subtitled version.

In the dub: damn, hell, bastard, ass, bitch. Quite a few uses of shit.

Shizuo often smokes and the way he does it makes it look cool which may offend some parents.

A girl has her leg broken, realistic sounds are heard. A regenerative girl is non-graphically vivisected in a rather perverse scene.

Characters include a (sexually) warped scientist, and to a lesser degree, a smirking villain.

A slasher attacks random people, although none are killed.

If this series were to be rated by the MPA it would be rated PG-13 for violent content, some bloody images, nudity and language.
