It is a series of powerful events and childish adventures. The story tells of a boy named Yousuke Oramichi, 14, the worst student in his class because he is a rioter and always goes into fights with others. It seems that Yousuke will turn to someone else when he died in order to save a small boy from traffic. After that strange behavior of Yossuke, it seems that he will pass through an ordeal to recover his body and become a spiritual detective to do more.
While Yu Yu Hakusho is pretty much everything people who avoid anime because they watched one episode of a Dragon Ball property and didn't like it would assume it to be, it's also, quietly, an extraordinarily sensitive show.
You need strong writing, characters you care about and tons of action. Needless to say, the anime (and its manga and movie versions) have all these goods.
