Air gear rocks read the manga though. Much deeper into the rabbit hole, and does it really well. You get some cool little Psudeo-magic with a solid scientific background behind most of it. not seen Airbats, Soul Eater is cool but has a bad ending, not akuma no riddle that and FUCK NO!! FFFUUUCCCCKKK!!!!!!! NNNNNOOOOOO!!!!!!!! Try watching Buso Renkin dub, or....one of the Blood series. Apparently the others are good but (Blood-C I think) is the rotten dog-shit. With dying seals laying on it. Or try the Berserk anime. They took the pure gold that is the manga, and then rammed it so far up a hooker's hole it came out though her mouth covered in some of the worst filth in the world.
