I don't know what series you already watch, so I can't know for sure if these are 'new' to you, but I like FullMetal Alchemist, Aquarion, Black Blood Brothers, Inuyasha, Bleach, stuff like that. (Some of them I haven't seen much of but plan on pursueing.)Those are more serious, though, so you might like Shuffle!, Naruto, or Boys Be better. Hmm, although there was a lot of humor in between the bloody angsty stuff in the other series too lol.
I'd recommend checking out any of them, but they might not suit your tastes.
