Amongst the frequent and impressively depraved hentai component, there were actually small amounts of potentially interesting backstory, which left me wanting to know more about the characters and their motivations at the end of each episode. The characters all seem to have, or develop, some kind of mysterious agenda for reasons unclear. For me, familiar anime settings and character stereotypes helped make it more than just typical hentai 'porn'.
For some this might present a problem, and I'd only suggest people who don't take offense to 'inappropriate' themes watch this show, because it has plenty of them. Definately more suited to the open-minded audience able to distinguish fantasy from reality, and obviously adults.
What impressed me most was the sheer level of depravity, easily comparable to any western porn, while additionally integrating socially inappropriate themes that the latter generally dare not approach. The dilemma of the female characters, torn between emotional pain and physical pleasure (but ultimately having no say one way or the other) highlights a strong psychological component to the characters and story, though this was really only touched on.
Overall a combination sure to please any pervert with a tendancy towards the more lewd romance/echhi/harem anime, which currently leaves plenty to interpretation and imagination. The fact it's censored really didn't seem to be a big issue; the rapidly degenerating 'immoral' behaviour of the characters easily overpowered any possible perception of decency or dignity that a bit of mosaic censorship might impart.
Obviously hentai can't be rated in the sense of a normal anime, thus my scores reflect its merits based on what it is, as well as comparitively.
For so few episodes, story was 8/10, a proper series would have real potential. Art was also very good, not over the top, 8/10. Voice actors were superb and did not sound like they were hired from a Japanese porn set, 8/10. Characters appeared well conceived, with potential, 8/10.
Overall enjoyment wise, I have to admit was pretty high. Generally speaking, pretty much all of the hentai I have watched up to this point has just been generic crap, with little to no story, drama, or character development. This was by no means perfect, but it also took me by surprise.
Oni Chichi combines anime, porn and signature Japanese inappropriate themes and taboos into something so wrong, that it must be right. 8/10
