Hen Zemi is an OVA based on its original manga of the same title, which stands for Hentai Seiri Seminar (変態生理ゼミナール, Abnormal Physiology Seminar). Some people may describe this show as R-Rated version of Seitokai Yakuindomo, and it is partly true. However, instead of high school students making frivolous jokes about human sexuality, you will see a team of college students doing live-experience research on perverted behaviors of human under Professor Meshiya’s guidance.

Let's review the story:
First episode is pretty funny, but the name is too long and difficult! 6.0
Second episode is very funny, pervy, great! That WAS awesome! 10.0
The third episode is really stupid. Why add another girl to the show?! 4.0
The story is fair.
