Yu Yu Hakusho (1992)
Young Yusuke Urameshi was having an ordinary day: skipping class, arguing with his teachers and picking fights with his rival, Kuwabara. But, contrary to his reputation as a troublemaker, Yusuke reveals that he has a good heart when he jumps in front of a car to save the life of a little boy. And then everything changes. Guided by the friendly Botan, Yusuke ends up being taken to the Spirit World. There, he meets the amusing Koenma, a 700-year-old ruler trapped in the body of a baby. And the big surprise is that he has a challenge for Yusuke that could restore his life: hatching the egg of a spirit monster. At the same time, the boy will have to help Kuwabara, his former nemesis, deal with a new gang of enemies. Then Koenma sends Yusuke to the human world to find out if anyone still wants him back, after all...
