Ghost Fighter Episode 1 – Surprised to be Dead

Yusuke Urameshi is hit by a car after saving a child who was playing with a ball in the street. He soon learns that the child would have lived anyway, and that the Spirit World was not expecting him to die. For this reason, he is then offered the chance to be revived by the mysterious Botan, Guardian of the river Styx. He initially refuses but accepts after seeing the people he thought did not care for him, including his childhood friend Keiko Yukimura, his mother Atsuko, and his rival Kazuma Kuwabara grieving for him at his wake.
