Choosing which high school club to join can be a daunting task. After all, there are only so many hours in the day, not to mention the power struggle between cyborgs and part canine-females. At least, that's the conundrum that Haruki Komaba finds himself trapped in.

Airi Kuze is a mechanical science master with a crush on Haruki. Touko Hizuki is a half-dog, half-girl chemical science master who's also fond of Haruki. Unfortunately for Haruki, he accidentally promised to join both clubs and finds himself in the middle of a fierce battle for his membership and, if Airi has anything to say about it, his hand in marriage.

As if things weren't complicated enough, Ayana's perverted older sister Touko has decided to intervene on her younger sibling's behalf, bringing her own brand of sexually charged chemical science into the mix. Haruki's going to have a difficult time deciding on a club. If the girls don't end up tearing each other apart first, that is.


Kagaku na Yatsura’s single OVA came bundled with the limited edition version of the manga’s fourth volume.

For those who are planning to take a go at this title, at least skim through the first 3 sections of my review aside from this paragraph before you even attempt to watch this as it may not be for you. I'm not surprised to see the show receive low ratings for what it is but it does bug me when people who attempt to watch it and end up scoring it a 1 ~ 3 without even completing it or even dropping it after simply seeing Ayana appear with her ridiculously large breasts within the first minute of the OVA.

Genre: Borderline Hentai.

Read the above. Read it again.

If you don't want to experience extreme titillation (sorry, can't help myself), please avoid this anime. (Please don't vote it down just because it isn't what you were looking for!)

For people like me, this tour de force of gigantic breasted ecchi with fluid animation (another pun, though you won't get it unless you watch Kagaku na Yatsura) combined with a few genuinely funny moments is definitely worth a watch.

My rating is broken down as follows:

Story: 4/10 (decent) - the anime clues you into the back story (from the manga) but it's not fleshed out in any way.

Kagaku na Yatsura is a single episode borderline hentai OVA. To give an example of what that means, other borderline hentai are things like "Yosuga no Sora" and "Aki Sora." However, this goes even farther than those ones and gets about as close to being an actual hentai as you can without quite crossing the line. Kagaku na Yatsura features a plethora of fetishes including extremely large breasts, small breasts, tentacle rape, an android girl, aphrodisiacs, lactation, yuri, and an ox monster that only sticks around for about 10 seconds.

The story's plot is ridiculous and pointless as you would expect of something this close to read more

This is my first review (be gentle please). Quickie Review.

This is a borderline hentai 25 minute OVA anime. This has lots of boobs, girls moaning, and plenty of sexualized moments.
So if you're not into that this won't be for you. The story (if you want to call it that) is very bare bones (remember this is just an ecchi 25 minute OVA) with mostly super erotic boob scenes thrown over the course of 25 minutes. The fluid animation (boiiiiii) was dope and I personally really liked it. The comedy is hit or miss, I smirked a few times and laughed once (which is more read more
