If you want to read something different read this manga!
Although it is a vampire story, it's not a casual story you are used to see. It is pretty good, the end isn't the best one around but at least does not throws it all in the trash can. I got pretty hyped reading it, specially the early volumes. It does have a lot of Ecchi stuff but always perfectly mixed with the horror and gore the manga has. That for sure got me really into this manga.
The art is GODLIKE. Really. Read it even if you hate vampires. I got caught first by the art and the by the story. There are some scenes that are soooooooo fucking good I can't even describe it. Some characters could be more developed, but overall it is pretty good.
Ah, there's some point at the story that it gets so annoying and non-sense that you might think about dropping it but overall the end is pretty satisfying.
Hope you enjoy it.
