I don't remember if it's Accelerando or Stringedo, the one hentai with 12 Episodes. I still don't understand how such a horrible hentai had 12 episodes. But speaking about Oni Chichi... The main story is, of course, better than the side story (Oni Chichi 2 and Revenge), the art is superb and Airi's sex scenes are REALLY HOT!!!
The story is great and I simply love Airi, but further characters really sucks. Marina has a deadly body, but she's way too easy and Sana is a whore whose turns her ass to any dick in the corner. Oni Chichi 2 is overall good as well. Not so well developed story, but I simply love Airi's "Older Sister", Fuyu, that's. She reminds-me a lot of Airi, like a Grew up Airi. But further characters really sucks in my opinion, as well.
But overall, both series are really good, and, like I said, mainly the Main Story and it's a Must-see Series for Hentai Lovers. That's all to say.
