Raise your hand if you had ever watched something sexually arousing but at the same time repulsive and gross. Now, put down your hand if you're thinking about scat porn. Much better..
Basically, this anime is similar to scat porn. You're disgusted by it. You're aroused by it. You're wondering why they do it. You're wondering why did you even clicked on it when there's hundreds of other videos you could use for the daily "ritual". But at the end of the day, you still can't comprehend it.

Hen Zemi redefines the word "Abnormal"
Quite a refreshing approach from all the cliches in animes you see read more

All I can say is Wow. if you thought Hen Zemi was just about fart jokes and perverted comedy, you were wrong. Somewhere within the comedy lies some insight to the human psyche that really blows one away if you sit and think about it.

The review is after going through 9 of the episodes plus one of the OVA's. Originally, I picked this show up not knowing what I was getting myself into. All I knew is that it featured Hanazawa Kana as one of the main characters and that it was a comedy. When I saw some of the content the show had to read more

Time to get out of the kitty pool of hentai and the vast world of fetishes! The subtly of this anime in its innuendo makes me smile and its strange approaches to what we normally see in common anime brings me in closer. I feel though this anime is definitely wasted on any younger audience that views it.

Hen Zemi is a ecchi anime, the majority of the characters partaking in a variety of niche fetishes including NTR, bodily fluids and otherwise smut. In the thirteen episodes, Hen Zemi operates as one of the daily life styles seen in other series, however, the only twist is the cast of characters partaking in the college credit as a band of social misfits.

Hen Zemi appears to operate on the logic that, despite conversation ranging from a womans period to pouring the decomposed contents of a lover into themselves -- the viewer will be grossed out. I did not happen to be one of those read more

They both focus heavily on sexual humor (Hen Zemi focusing on weirder fetishes though).

Dirty sex jokes in both anime, although Hen zemi is even dirtier and more lewd. If you really like sexual humor and want something more mature and with more well thought jokes, go watch Hen Zemi. Be aware that HZ has some poop jokes and other gross stuff that may not be suitable for everyone.

Both have the "weird" seminar theme going on. The plots are really similar especially with the humor and both are great comedies, you'll understand if you've seen them both.

Anime: Panty & Stocking with Garterbelt
Both are TV series that are filled with erotic humor that pushes the limits of what can be shown on TV.> 
reportRecommended by Neane93
Anime: Genshiken
Both animes are about a character joining a group, and learning about themselves in the process.

Both are very funny, and deal with some of the more extreme aspects of society (extreme fetishes, extreme otaku(ism))

Anime: 30-sai no Hoken Taiiku
First of all - they're both about one's sexual life. They're also very strange and make me think "WTF is happening?". Both of them last for 12 minutes per episode and, finally, they're both from 2011 spring season.
