Yusuke Urameshi (浦飯 幽助 Urameshi Yūsuke?) is a student who attends Sarayashiki Junior High School. His poor attendance, constant fighting, and bad habits have earned him the label of a delinquent among most of his teachers and classmates. This all changes rather abruptly as Yusuke is struck by a car and dies while trying to save a small child who had wandered into the road. Such an altruistic deed catches the underworld by surprise. As they do not have a place for him yet in heaven or hell, he is permitted to return to his body and resume his life. However, while doing so it is revealed that Yusuke has a particularly strong aura or spirit energy, and Koenma, the son of Enma, lord of the underworld, recruits him as Underworld/Spirit Detective and Yusuke is charged with investigating supernatural phenomena in the human world and capturing criminals dealing in underworld crime.
