Hardly I ever write a review, but this anime was very intriguing, like nothing I've ever watched. In the first episode I'd call it a hentai, but the last one turned it more into grotesque sexual horror. The plot really brought me in, I was left wishing to know more. Not everybody's up of tea but if you can handle some heavy BDSM and guro, this is for you. Art as well is very pretty, at least for the visual novel of it (there is one, but I literally can't find anywhere to download it). Story is very unique and very unpredictable, if you're looking to watch hentai with anintriguing and odd plot, you should give this a try.
