my memory is a bit foggy but i remember its a manga about a man who killed many people and was sent to hell to be tortured for eternity and then he gets a chance to win back his soul but he has to kill or save 100..or was it 1000...evil people in order to get his soul back and the sword he uses is a wooden one but when the user has evil thoughts it becomes strong but if the thoughts are overwhelming the sword would absorb him....and when he was sent back to earth he met a girl and saved here...with a badass attitude so the girl takes him home because he is wounded..or something and he meets her grandfather and he feels like family to them...and thats all i remember please help, oh yeah and he cant kill any body just their evil intentions...and evil person would have like a spirit in them or telling them to act on these evil urges and the main character has to kill these souls...

It's Togari. Super coincidence, I was just thinking about it before I opened this topic.
