Absolute Anime

I got a result on a 'which anime guy would you end up with quiz' and it said Jirou Mochizuki. I had no idea who the heck he was, but he was cute, so I did a search for the name and came up with Black Blood Brothers. I've never seen or heard of the show, but for some reason I'm already in love with it! XD (Must be the vampies....)

Anyway, I was wonderin if anyone had seen this show, and if so, was it good?
Thnx!
