From Viz:
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 spirit guide of the dead, and Koenma, her pacifier-sucking boss from the "other side." But what strange things await him on the borderline between life and death?

Togashi released the official doujinshi Yoshirin de Pon! in 1994. It includes a few omake and a post-mortem interview that explains his decision to end it prematurely.

Note: Won the 39th Shogakukan Manga Award in the Shounen category in 1993.
