In 1995, studio...Ahem...GUYMAX made a fully-animated (if you can call it that) 12-minute long hentai short called The Human Instrumentality Project. Hilarity ensues.
Basically, Gendo calls Shinji to his office, where almost the entire cast are bonking each other. Then Shinji gets forced into it.
Oh, there are so many things wrong with this, so let's take it from the top shall we?
NOTE: This being a hentai OVA, the descriptions will be rather...colourful, hence the spoiler. Normally I wouldn't bother with this, but this is such a significant find, and it's so awful, it needs proper documentation.
Shinji: The "hero" of the piece. Forced to join in with Gendo's orgy. Can't decide whether he's his usual bashful, prudish self or if he's just going to get on and join in with the fucking. For some bizarre reason, he's voiced by a guy, and instead of Megumi Ogata's dulcet tones, we have one of the most annoying, whiny voices known to man. Seriously, the guy voicing Shinji is so bad he's practically unwatchable. Easily the worst voice in the entire thing. Which is funny considering the real Shinji has a voice that could soothe a rabid lion. Or at least, in Japanese.
Misato: The only character who sounds remotely like her original self. Even when being porked from all angles, can't resist a "saabisu, saabisu!".
GENDO: Maintains his pose throughout the entire thing. Literally, the entire video. Whilst being fellated. Frighteningly in-character.
Rei: Dear god, what have they done to her? Casually walks in smiling and immediately starts trying to get Shinji to bone her. Partially succeeds. Only complaint about getting spooged in the face is that "It's a little yellow...". DEAR GOD. Also sounds nothing like she should.
Asuka: Suddenly a shag-happy genki girl. Until a bunch of random bridge bunnies and Kaji give her a faceful (and arseful) of baloney pony, upon which she begins crying. Very unconvincingly.
RITSUKO: Not a lesbian for some reason (Maya is suspiciously absent). Exhibits mild surprise at being repeatedly shagged. Also seemingly teleports onto Shinji's face. What is it with hentai and miraculous position changes?
Kaji: Appears out of nowhere to stuff his progressive sausage in Asuka's poorly drawn mouth. That's it.
HIKARI/TOUJI: The video occasionally cuts to these 2 getting it on. The exact same still frame in fact. What they're doing here is anybody's guess.
PEN-PEN: Mercifully absent.
The voice acting:
Horrendous, to put it mildly. Shinji is easily the worst, sounding like a wangsty 19 year old with a cold. For fuck's sake, is it that hard to find a woman who can do a passable little boy voice?
Good grief. The animation is beyond terrible. Numerous off-model moments, overuse of still frames and reused footage, a repeated clip of very, VERY crudely drawn intercourse in what looks like Tron graphics, and to top it all off, a very dodgy idea of how plugsuits work (according to these people, the central piece is just a one-piece swimsuit that isn't attached to the legs or arms at all and can be pushed out of the way for superior bonking). It even reuses footage from the actual show (to be precise, Gendo smirking from under his palms).
Plot: I think there was one, judging by the interrupting text crawls. Whatever it was, it was about as deep as Shinji's chest- that is to say, non-existent.
Fappability: Makes use of awful light beam censorship, and the shagging is too crudely animated to be titillating anyway. Coupled with the over-abundance of poorly drawn fluids, crappy animation, horrible voice acting and...interesting attitudes to character, this is completely unfappable.
Overall, an absolute mess that is only watchable for bile fascination/laughter.
VERDICT: Release Bakelite.
Fairly obviously, I am not going to link to it because that would be against the rules; I'm not even sure I should be talking about it. If you want to see the abomination I can PM it to you. Just...make sure you have a therapist lined up.
