Yu Yu Hakusho is a series about 14-year-old Yusuke Urameshi, who is having a typical day. He's cutting class, arguing with teachers, and getting into fistfights with his rival Kuwabara. But when Yusuke dives in front of a speeding car to save a little boy, things take an unexpected twist!
As a result of his self-sacrifice, Yusuke is taken to the Spirit World where he meets Koenma, a 700 year-old ruler with the body of a toddler - pacifier and all! There's no room for laughs, as Koenma gives Yusuke an ordeal that could restore his life - or end all chances for revival. Back in the flesh, Yusuke finds he can see supernatural creatures hiding in the living world. But with this strange new ability his adventure is only beginning. It seems Yusuke has become a Spirit Detective, and must track down evil spirits in order to stop them from fulfilling their diabolical plans!?
