Query: Interesting beginning

I'm not a huge fan of anime (my knowledge of it is pretty much Speed Racer and Gatchaman), but I wanted to give this a try. The storyline is a battle against the vampires thing (like Blade), but the story is much deeper than that. While the storyline it tells comes to a partial conclusion, there are still many plot threads left open for the next chapters that follow. Also, since this deals with vampires there are a number of scenes that get fairly bloody, so this isn't necessarily for the kids. Still, the characters are interesting and there's definitely enough action to keep you watching and even wanting more when it's finished.
