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.
Dr. Ichigaki's ultimate biological weapons are in the ring, but Team Urameshi is suddenly having a severe attack of conscience. After Kuwabara's enlightening reverie about how Dr. Ichigaki implanted blood-slaver nodes in the brains of Master Mitamura's martial-arts students, Yusuke and company just don't have the heart to conduct their demon-slaying business as usual.
Meanwhile, the Shadow Channelers--the ninjas of the Demon Plane--are on deck. With their fiendish adrenaline pumped up to the max, Team Urameshi better pray that Yukina the Ice Maiden, who came to watch, turns out to be their lucky charm.
