Firstly, im not usually into hentai, but i do enjoy adult anime, which happens to include sex. Having said that, i actually quite enjoyed this anime, as it had a quite interesting story line. there were a handful of sex scenes where i thought eh why, but that is to be expected from hentai, but on a whole, the sex actually was integral to the story. i enjoyed the immortal/vampire element to this anime as it was an unusual take on the myth. the were some elements in this hentai which made me uncomfortable, but i was able to get through it becausethe story was strong enough to make me want to keep watching.

All in all, watchable for non hentai fans on the grounds its a good immortal themed anime, but could have been alot better had it not unfortunately focused more on the hentai aspect.
