Yuusuke is a 14 yr. old punk-ass kid with a bad attitude. One day, he actually does something good, throwing the balance of his fate off the handle, dies, and has to earn his way back into existence. When that`s over with, Koenma (Prince of the Underworld + in charge while King Enma is away) wants Yuusuke to become a (we`ll just use the translated terms) Spiritual Detective + hunt out the bad guys of the Demon World (Makai) and ship `em off to the Spiritual World (Reikai). Yuusuke is joined by local bully and cat-lover, Kuwabara Kazuma, (who has the 6th sense in training), Kurama (reincarnated Fox Demon aka Youko ), and Hiei (cute, short, pissy fire demon).
