Ow that usWhat's the name of this cartoon/anime shed to show on cartoon netw!

I remember that the main character always wore a green suit, and at the beginning he was a jerk!. One day the character sees a little kid chasing after a ball that went into the street and he pushes the little kid out of the way but he dies!. He's sent to a 'spirit world' where he's told that he wasn't supposed to die and since he did a kind deed he would get to go back to life to fight monsters/demons or something!. His master was an old short woman!. I remember in one episode she gives him a ball of 'energy' and that when he tries absorbing it he can barely stand it!. He had an 'egg' that contained an animal that represented him and it turned out to be some cute thing with ears!. This is all that I remember, do you know what the name of the show is!?Www@Enter-QA@Com
