The first thing I noticed, is that this anime is a mix of so many style, that it could've easily gone bad, in this you will find:Action,Harem,Supernatural,magical girl,ecchi,comedy and romance.
luckily, I enjoy all of these themes, actually, I enjoy pretty much any kind of animes as long as it's well built, I guess some people could be turned off this anime because of only one of those themes, it is indeed a huge risk that the author took by going that way.
In any case, I won't spoil for now, but I find the story very interesting, at least for now, good twists, a lot of surprises, very nice character design,the sound is nothing special but it's not disturbing as well. technically, that anime is doing great.
I suggest everyone to give it a try, it's worth it, but I can easily understand anyone who don't like...
NOW if you want some infos about the story itself, that's how it goes, a casual boy was victim of a serial killer in a small city, but a necromancer reanimated him, giving him at the same time immortality, he is, literally, a zombie, for various reasons he and the necromancer then group up with a masou shoujo as well as a ninja vampire, it's only then that they are threatened by an evil mind from another world, I don't know what follows for now, just watch it, and you'll know too :)
