YuYu Hakusho, Vol. 3 : In the Flesh (Yuyu Hakusho)

A delinquent’s gotta do what he’s gotta do…in the afterlife. Yusuke Urameshi was a tough teen delinquent until one selfless act changed his life...by ending it. When he died saving a little kid from a speeding car, the afterlife didn't know what to do with him, so it gave him a second chance at life. Now, Yusuke is a ghost with a mission, performing good deeds at the behest of Botan, the ferrywoman of the River Styx, and Koenma, the pacifier-sucking judge of the dead. Yusuke Urameshi is back! When the teenage delinquent surprised the Underworld by dying heroically, he was given a chance--just one--to return to life. Now, having passed his trials in the spirit world, Yusuke is back in his body and ready to reclaim his turf from the other street punks. But for someone who's been to Hell and back, a normal life on the streets is no longer possible. Yusuke picked up some otherworldly powers while he was dead, and the Underworld is about to offer him a job as its official supernatural detective!
