I thought the anime, OVA, and recap were much worse than this, so they got lower scores. As far as a manga goes, it wasn't good by any means, but perhaps I was more positive about it after seeing the train wrecks that were the animes. You had more character in the manga and some of the boys, while all of them were still pretty twisted, had some semblance of a character. Some were better drawn than they were animated and there were some actual cute moments, though the assault didn't cease. However, the assault didn't really feel like assault here, because Yui is revealed to be a masochist and genuinely enjoys some of the stuff the boys do. While she still doesn't enjoy everything, this is a lot better than the blank, noncensual scenes in the anime.

Overall, a large improvement from the anime to say the least. That being said, I would like to point out this doesn't have very much plot either way. I would suggest treating it like a fanfiction-- you choose your favorite boy and read a somewhat-sexual one-shot dojinshi about them. Or, read for all the boys, like I did. I still despise Kanato and some of the other boys I find a little bland or more than a little twisted, but even then, I actually found some of the chapters genuinely enjoyable, to my own surprise.

I recommend this if: you like sadism/masochism, you like vampires, you like the 'one shot' style without a big underlying plot, you're looking for some fun manga you don't really need to connect to, you adore vampires

I would NOT recommend if: you are looking for character development, plot, want some sort of conclusion, prefer 'vanilla' relationships, like 'nice' guys

Have a great day everyone!!
