Yusuke Urameshi is a street-brawling delinquent with a tough guy approach to everything.However, no one expects a sudden act of heroism on his part: he dies trying to save a little boy from a speeding car. In fact, when he arrives in the afterlife, he is informed that no one was expecting him to die that way, and were not prepared for his arrival. After numerous tests to gauge his worth, Yusuke is eventually revived, and is assigned to work for the Spirit Realm as a detective investigating demonic cases in the human world.
