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.
You'll cum all over far before the OVA finishes it's 25-minute runtime, but then unlike most porn you'll keep watching, hearty laughter spilling out as you watch the utterly ridiculous erotica taking place on the screen. A must-watch. If this is borderline hentai then Hitler was a borderline racist.
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.

As of now, the time of its release, I would personally have to say that Kagaku na Yatsura has raised the bar for all future borderline-h anime to be with its incredibly explicit scenes and quite fantastic quality. I'll get a bit more into detail later but that's enough on the intro, let's get onto this review.
Story - 5/10 - Kagaku na Yatsura revolves around Komaba Haruki, the main male protagonist and his two female friends who are trying to get him to join their club. Although this is irrelevant in the OVA as you won't get much into it. The entire episode consist of him and the girls getting into several erotic and problematic situations which are all solved through the girls climaxing.
When you think 'good story', you usually think of 'plot' which leads to thinking something along the lines of conflict and progression the characters go through. Well Kagaku na Yatsura doesn't provide this, it's a single OVA, so of course it won't provide any deep meaning or any sort of spectacular plot and development. The fact that it's a ecchi romance comedy should be enough to know you shouldn't be expecting much out of it in terms of plot.
Also to think about, would you rate an anime title lower simply because it was a single OVA adaption of a manga and didn't get much adapted because of its length or would you rate it higher because of how it managed to adapt what it could for its duration of a single episode? I feel Kagaku na Yatsura provided a very good amount of an adaption for the single OVA and although it didn't adapt it from the first chapters of the manga, for the chapter it did, it adapted it panel by panel, page by page. So because of this, I am giving this anime a neutral score in this category.
Art - 8/10 - When it comes to hentai, you usually get a few h-scenes which are looped over and over while some even repeat and are reused again. Kagaku na Yatsura isn't too different but at the same time it does it so much better. When the show does decide to loop a erotic scene, it doesn't loop very long before moving to another point of view or angle, providing a new animation and thus providing even more variety of the erotic scenes nor does it bother to ever bother to reuse old scenes. The color quality of the episode was simply spectacular for a show of its kind, full of vibrant colors and just a little extra to mention, since this is not an actual hentai, you don't have to even worry about censorship!
Sound - 5/10 - There was nothing notable about the music for this show but it wasn't as if it was bad or anything.
Characters - 7/10 - The characters were one of the best parts of this show next to the art. The show does jumped in with a rushed start as it doesn't provide anything in-depth about the characters where it simply shows the characters being themselves without any sort of explanation as to their roles or who they are, although this can be solved ahead of time with a quick glance through the plot synopsis and the character details and honestly, it shouldn't be too hard to guess their roles in this genre of show. There clearly will be little to no character development of any sort because of the genre and length of the show. Each character do provides their own form of enjoyment and sense of humor which can increase your overall enjoyment and what makes this category get extra points in.
First off, to mention again, we have Komaba Haruki, who is the male main protagonist of the title. There isn't much to say about him from the OVA other than he's you're typical highchool boy lead stuck in-between a couple of girls who like him and tends to just be there for the sake of having a male character on the screen. He does provide some level of humor when the girls get into erotic situations and does get to be part of the fun during the last scene. Though heck, we all know its all about the girls which makes a ecchi anime what it is, so let's move onto the girls.
Next, with Haruki also we are shown Kuze Airi, a shorter blond twin tailed girl who is part cyborg as well as what I would consider a loli for her size. Her cyborg functions can range up from changing her arm into a chainsaw, her hands into gatling guns, her eyes include in-depth sensory vision and even her backpack provides quality fun with its many robotic arms and hands. She is a bit lacking in the chest department but I'm sure that won't bother many people, heck, I'm sure many will love her because of it, I sure as hell do.
Then we got Hizuki Ayana, the extremely big busty part dog girl. She ended up becoming part dog through her experiments and a side effect of it is that she now lactates milk from her breasts and they've become extremely sensitive. She is portrayed as the target of most problems that occur. She's constantly getting herself into some situation or being targeted by others into one and in some cases, getting others involved with her. If there was an obvious trap, she's the kind of character that would end up triggering it by accident. She's basically a ditz who isn't aware she is a ditz.
Lastly, there is Hidzuki Touko, who is Ayana's older sister and during second half, becomes the school nurse. Unlike Ayana, she's isn't part dog or anything but she is indeed just as busty as her and has the ability to turn invisible. Touko is more of a mischievous woman as you can guess with someone with the ability to turn invisible but her character truely shines from her ability as a chemist. She's concocted all kinds of strange potion with all sorts of effects, especially ones that make others obey whatever you say and ones that make you more sensitive. .
Enjoyment - 10/10 - I'm going all out fanboy on this category. I enjoyed this series to its fullest. I can't say I ever liked extremely huge breasts, heck, I'd say I detest them but somehow I wasn't bothered in the slightest bit from this show and just because of this title, I am willing to try open myself more to that genre. As a fan of tentacles genre hentai, I loved the tentacle related scenes used and the quality of the entire episode. It doesn't matter if there was no actual insertion or genitals showed, this level of ecchi surpasses just about any hentai I have enjoyed. The comedy was a great addition as well, especially considering the fact that I don't fluently understand Japanese and still managed to burst out a few laughs watching the RAWs. Hell, I even typed up this large review for its single OVA because I enjoyed it so much.
Overall - 35/50 -> 7.0 out of 10 - As you can see, my enjoyment score did bump the overall to a 7.0, if I had not include it, the score would have been a 6.5 out of 10, which still rounds up to a 7.
For you who love extremely huge breast that also include lots of lactation and tentacle hentai, if you run out of hentai or hardcore ecchi to watch, this is a great choice and you'll be thoroughly pleased. Although if your not very fond of extremely huge breasts, tentacles, or ecchi in general, I would recommend you avoid this title as it will not be something you will enjoy.
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.
6 (fair) - be warned that this anime contains the kind of orgasmic moaning and screaming that is normally found in hentai; the music didn't hurt my ears.
Character: 6 (fair) - a perverted but otherwise normal protagonist, a delicious flat chest, and two big (read: BIG) busted beauties.
Animation: 9/10 (great) - with clearly visible breasts and butts and no genitalia shown (which would severely limit its availability to a smaller audience in Japan), it has higher production value than most regular hentai; did I mention "fluid animation"?
Enjoyment: 9/10 (great) - it was extremely titillating.
Overall: 9/10 (great)
As you can see, I have weighted the overall rating to reflect what matters most in an ecchi anime/borderline hentai - animation and enjoyment. I could have also included sound in the overall rating but, since it was good enough that it didn't detract from my enjoyment, I excluded it.
Bottom line: it's very underrated for its genre. While it lacks plot development, it should immensely satisfy the majority of people who watch it knowing what they're getting into.
P.S. It's unfortunate that some felt compelled to bomb its rating. This probably could have been avoided if there were a "Borderline Hentai" genre tag.
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
being a hentai. It's about two girls fighting arguing over who gets to marry the male protagonist and have him join their engineering club (one studies chemical and the other mechanical engineering). The chemical engineering girl also has an older sister (who is just as extremely busty as she is) who acts as a catalyst causing several different problems during the episode. The two girls get dragged into different sexual situations and have to work together (or against each other) to get out of them (or not) and to win the affection of our main "hardly necessary for anything other than being the cause of everything" male protagonist.
The sound during the sexual scenes (I say sexual because no actual sex happens) mostly consists of instrumental hard rock pieces. They didn't really stand out surprisingly enough, and I didn't notice them until later in the episode so I really have no idea what the soundtrack was like early on aside from some casual background sounds during the less-sexual scenes. Also, the voice acting is average and isn't really bad, but there are no great performances either.
This is really pointless in my opinion. Either, they should have gone all the way and made this an actual hentai, or they should have tuned it down a little and made it a more normal ecchi show (maybe so there would actually be clothes that exist in that universe that fit the two busty characters without their nipples showing through it). The art is pretty good quality in and of itself, but the character designs, weird tentacle rape that only consists of nipple sucking, and other things just totally ruin any chance of the animation being enjoyable. The story and characters are really only there to make all of the fetishes possible and the story never really goes anywhere (well it is an almost-hentai so I wasn't expecting much anyway). I recommend not bothering with Kagura na Yatsura and instead settling for either an actual hentai or something tamer (even Yosuga no Sora or Aki Sora [the borderline-H series I referred to before] are better than this).
