From the amazing author of BLEACH, Tite Kubo, it's Zombie Powder!

I don't quite understand the plot myself yet (I got Volumes 2, 3, and 4 today), so... here, the Wiki about it, but don't read too far if you don't like spoilers!

It's about Gamma Akutabi, a Powder Hunter (by that I mean he's a hunter looking for Zombie Powder which can bring back the dead and give the living eternal life) who is looking for the Zombie Powder's power source, the 12 Rings of the Dead with his partner C.T Smith and his flunky Elwood. Also with them, Wolfina Getto, the female character. She's, um, Orihime-ish in appearence. In personality, no way, just appearence.

Anyway, it's superspecialawesome and if the manga can be found online, read it! :D

And for anyone who may not know, Grimmjow Jaggerjack/Jeagerjaques's design is based heavily off of the main guy from this manga.

Haven't read it, though (though since it's supposed to be pretty short due to it being discontinued for whatever reason, I'll probobly read it at some point).

It IS short, 4 Volumes, and you can read them all here.

All I know is that Tite Kubo faced some personal problems or something and had to cut ZB short. The ending isn't TERRIBLY dissapointing, considering. I wish it hd continued, though.
