DONT BE FOOLED BE THE 1,2, and 3 reviews try it for yourself ad see if it suits you.
I love the show, it does well in telling a complex story in only a matter of 12 episodes, yes it has implied rape, sadists, and masochists, but it tell how vampires are really seen by the public, where they see people as nothing but food, but the show is good to were the start to treat Yui nicer along the way, Zexces did well with the animation and design, i couldn't ask for any better, the show starts slow but pickes up episode 7.
I would recommend it to anyone that likes this kind of stuff.
