ข้อมูลอนิเมะคนเก่งทะลุโลก

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 Urameshi, and his rival Kazuma Kuwabara grieving for him at his wake.

Yusuke meets Koenma, son of the ruler of the Spirit World, and is given the task of raising a spirit egg that, when hatched, may return him to his body. Yusuke possesses Kuwabara's body to inform Keiko about his attempting to come back to life so that his body will not be cremated.

Yusuke discovers that Kuwabara has been forced by a teacher into a policy of strict nonviolence for a week — otherwise his best friend risks losing his job and being unable to support his family. Kuwabara bears the attacks, and when the teacher puts an additional stipulation that he and his friends must get more than 50 points on the next test, Yusuke helps him study by talking to him in his dreams. The teacher attempts to cheat his way out of the promise by altering Kuwabara's paper, and Kuwabara almost punches him, but Yusuke calls out for him to stop. The teacher is forced to change the paper back, and Kuwabara's friend keeps his job, with Kuwabara thanking Yusuke.

Yusuke's house was set on fire while his mother was gone and Yusuke has to decide between saving Keiko or having any chance of returning to life. Yusuke chooses to throw his spirit egg into the fire to save Keiko, and by doing so, earns the right to return to life.

Yusuke is told by Koenma that he has one final chance to come back to life, but only if someone close to him kisses him within twenty-four hours. Trying to solicit Keiko's aid, Yusuke manages to have Keiko kiss him just before the deadline.

Koenma reveals that Yusuke is a Spirit Detective, and must use his unique abilities to battle demons and other threats to the Living World. Koenma additionally gives Yusuke a mission: he must recover three artifacts stolen by master thieves of the Spirit World.

Yusuke discovers the first and second thieves, and the artifacts. Gouki, the first thief, possesses the Orb of Baast, and Kurama, the second thief, has the Forlorn Hope. Yusuke defeats Gouki, recovering his artifact. He meets with Kurama and learns that he plans to use the Forlorn Hope to sacrifice himself to save his human "mother." Yusuke, believing that Kurama's sacrifice would cause his mother pain, gives some of his life force so that Kurama will not have to die, and claims the mirror.

Yusuke battles the last thief, Hiei, who has taken Keiko hostage to get the last three treasures. With Hiei's Jagan eye affording him additional perception, Yusuke finds his fight difficult, but he manages to trick Hiei by firing his Spirit Gun off a mirror in order to hit Hiei in his blind spot, defeating him.

Yusuke enters a fighting tournament at Koenma's behest. The winner of the tournament gets to learn the secret techniques of Genkai, a master psychic, and Koenma knows that there is a demon named Rando who will be after Genkai's techniques. To his surprise, Yusuke finds his old rival Kuwabara at the tournament, seeking to learn more about his powers. Yusuke and Kuwabara inadvertently qualify for Genkai's tournament due to their high amount of spirit energy.
