I just started reading this recently, and I think this could turn into an awesome series. It runs in shounen gan gan, and is currently on chapter 13. Manga-Rain has scanlated the first two volumes.
The story follows six servants of Shinigami-sama, and a shinigami-in-training, as they collect and devour evil souls. It's something like a cross between The Nightmare Before Christmas and Shaman King, with lots of sex jokes thrown in. The artwork is very nicely done, particularly the sun and moon.
