Yu Yu Hakusho - The Spirit Detective (1992)

Yusuke Urameshi is having a typical day. He's cutting class, arguing with teachers and getting into fights with his rival Kuwabara. But then Yusuke does something that betrays his killer rep. He dives in front of a speeding car to push a little boy out of harm's way! Yusuke has sacrificed his life for the sake of another, but is this really the end of this brash young man?

Pulled by the sprightly, pink-robed Botan, Yusuke enters a realm that is not quite normal -- the Spirit World. There, Yusuke meets Koenma, a 700 year-old ruler with the body of a toddler, pacifier and all! But there's no rom for laughs as Koenma gives Yusuke an ordeal to restore his life. Hatching a Spirit Beast!

Kuwabara was tormented by his rival's death. The loser in all 156 of his brawls against Yusuke , he's now lost any chance he ever had of evening the score! But with Yusuke out of the way, Kuwabara is the new kid to beat... which means he's making plenty of enemies. Yusuke isn't fond of this classmate, but if he wants to win back his life, he will need to give him a ghostly hand.

The Spirit World forgot an important question -- does anyone want Yusuke back? Koenma sends an Investigator to find out, and Yusuke's friends answer quickly when a fire threatens to char his earthly body. But will Yusuke give up the Spirit Beast, his one chance for revival, to rescue his friends?

Yusuke has reclaimed his life, but has only one day to be revived by someone's kiss -— And that someone might be Kuwabara! Back in the flesh, Yusuke finds he can see supernatural creatures hiding in the living world, and quickly hunts down a demon criminal. With this move, he learns his adventure is only beginning. Yusuke is a Spirit Detective.
