Yoshihiro Togashi's manga series Yu Yu Hakusho contains a widely diverse cast of fictional characters. At the forefront is Yusuke Urameshi, a 14-year-old typical school punk with not-so-typical pastimes. After dying and being resurrected Yusuke becomes the detective of paranormal events in the human world. The other predominant characters consist of Yusuke's family, schoolmates, friends, allies in his detective work as well as the higher ups in spirit world who give Yusuke his cases. Yusuke begins his work in the human world, but ends up traveling to the Underworld and then eventually to the demon plane. In each case he undertakes, Yusuke meets several new enemies and allies.

Yusuke Urameshi (浦飯 幽助 Urameshi Yūsuke), age 14, 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. Yusuke bears a bit of affection for his childhood friend Keiko Yukimura, who initially takes a role as Yusuke's conscience, making sure he comes to class and behaves, and later becomes his romantic interest. Yusuke's alcoholic mother, Atsuko, raised him as a single teenage mother after conceiving him with her then-boyfriend when she was 14 herself. In the end of the manga, she is shown being reunited with a former lover, who is implied to in fact be Yusuke's biological father.
Yusuke's most common attack is the Rei Gun (霊丸 Reigan, lit "Spirit Sphere", pronounced as "Ray Gun") ("Spirit Gun" in the English anime dub). Aura/Spirit energy is concentrated into his right index finger and released as a projectile as though his hand were a gun and his finger the barrel. At first he is only able to muster a single shot per day, but as he trains with Genkai he is able to fire multiple shots per day, as well as developing minor variations on the technique such as the "shotgun" variant wherein Yusuke fires a spray of miniature spirit guns at once using his fist instead of his finger. Yusuke is also the direct descendant of the demon king Raizen (though it is never specified whether the relation is from his mother's side, his father's side, or both) and, ever since his resurrection during the Chapter Black arc, retains his demon side and demon energy more than his human side. At the end of the manga, Yusuke opens up a ramen shop, and also spends time helping humans and demons learn to cooperate.
