Wholesale YuYu Hakusho, Vol. 1 by Yoshihiro Togashi

[Viz] 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.

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.
