Hen Zemi was an awesome anime. They somehow managed to make a cute college kid anime mixed with the most perverted stuff I have ever seen in a non-hentai anime. The idea is the characters are taking an abnormal psychology seminar, about extreme fetishes, but they get all sorts of perverted assignments. They also talk about and sometimes do all sorts of fetishy things. Most of the people (boys and girls) are there because they have an abnormal sexual side; the exception is the main girl who is very innocent and gets dragged into situations and discussion she is unprepared for... Its very interesting because itis both disturbing, funny, and sexy all at the same time. I can't think of another anime quite like this one; the closest I can come up with is FLCL, but Hen Zemi is rated 17+.

Further on that note, it is definitively not for minors; they talk about sex and all sorts of perverted things. Occasionally there is a medium-explicit sexual scene.

In conclusion, if you have a perverted side, and like funny animes too, this might be for you... but its probably not for you if you don't have a perverted side.
