A "science trouble" romantic comedy OVA bundled with the manga's fourth volume. It follows a high school boy named Komaba Haruki and his two girl friends: the cyborg girl Airi, and the half-dog girl Ayana. The two go to extremes with the power of science, which only gets Haruki involved in ecchi troubles.

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.

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

Anime: Eiken: Eikenbu yori Ai wo Komete
Both are Ecchi OVAs that accurately depict women and human anatomy.

Anime: Oyakodon: Oppai Tokumori Bonyuu Tsuyudaku de
Both contain characters with enormous breasts.
Both contain a lot of lactation.
Neither of them contain any penetration.

Anime: Asa made Jugyou Chu!
- Borderline hentai
- Women who are so busty that their nipples show through their shirts
- A small amount of yuri
- No real sex, just a bunch of other things that appeal to certain fetishes
- Set around a high school

- Kagaku no Yatsura is a bit more extreme (some tentacles and stuff) despite not really being a hentai

Anime: 15 Bishoujo Hyouryuuki
They fit as many fetishes as they can possibly fit into an OVA. Both have pretty good animation. Kagaku na Yatsura is just borderline hentai while 15 Bishoujo is a full-on hentai.
