Yu Yu Hakusho
- 4 Seasons
Yu Yu Hakusho follows the adventures of Yusuke Urameshi, a street-fighter punk who is fatally hit by a car while pushing a young boy out of the way. His risen spirit is met by Botan, a woman who sends souls across the River Styx to be judged for eternity. Botan explains that Yusuke's act was so out of character that it caught even her kind by surprise and that there currently isn't a place for him in any afterlife realm. Koenma, son of the Underworld's King Enma, makes a bargain with Yusuke; Yusuke can return to the mortal realm after completing a series of tasks. Thanks to the help of Yusuke's friends Keiko and Kuwabara, Yusuke is returned to life as an Underworld Detective who must investigate supernatural goings on in the human world. Not soon after Yusuke is returned to life, his first case rears its head. Three Underworld treasures were stolen by a gang of demons. Thanks in part to his unusual methods as well as his supernatural special attack known as the "Rei Gun," he manages to recollect the three treasures. Some time later, Yusuke must travel to the mountains to find an aged, female combat master named Genkai. Yusuke joins Kuwabara in Genkai's tournament, with the winner declared Genkai's successor. Yusuke joins the tournament as a cover to find Rando, a demon who steals martial arts techniques and kills the user. Yusuke manages to defeat Rando in the final match of the tournament, receiving several months of training and spiritual focus from Genkai. With his training finished, Yusuke is sent to the Underworld's Maze Castle along with Kuwabara as well as Kurama and Hiei, demons from Yusuke's first case who have since reformed, to assist in defeating the Four Beasts, Byakko, Suzaku, Genbu, and Seiryu, who plan on blackmailing Koenma into separating the Underworld-Humanworld barrier. After the Four Beasts are soundly defeated, Season 2 opens with Yusuke participating in the Dark Tournament along with his teammates Kuwabara, Hiei, Kurama, and Genkai in disguise. The ultimate goal of the tournament is revealed with plans to create a large hole between the Demon Plane and the human world. Yu Yu Hakusho is a 112 episode, four season anime produced by Studio Pierrot.
