Yuyu Hakusho, Vol. 12 - Yoshihiro Togashi

When teen delinquent Yusuke died saving a little kid, 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 judge of the dead.
