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. Some people may describe this show as R-Rated version of Seitokai Yakuindomo, and it is partly true. 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).
