YuYu Hakusho, Vol. 9 (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. After Yusuke Urameshi grounds a "flighty" Jin for good, Team Urameshi should be one step closer to victory. But thanks (more like no thanks) to a pervading conspiracy among the organizers of the Dark Tournament, Team Urameshi's plate is wiped clean of soldiers left to fight in the twisted event. Meanwhile, Genkai formally reveals herself to Yusuke and gives him the final test to be the sole heir to her formidable technique--a concentrated ball of aura! But due to the conditions surrounding his "second life," Yusuke must be ready and able to inherit the technique...or he dies!
