YuYu Hakusho: The Movie:

Yusuke Urameshi is not exactly what you'd call an angel. In fact, some might call him down right devilish. But when he dies in an accident trying to save a child, he finds himself in the Spirit World, too good for hell, but not good enough for heaven. Now Yusuke works as a half-dead, half-alive agent for Koenma, son of the ruler of the Spirit World. This position does have its disadvantages, especially after Koenma gets kidnapped, and Yusuke must find Koenma to trade the Golden Seal of King Enma for his life.
