Yu Yu Hakusho (Japanese: 幽☆遊☆白書 Hepburn: Yū Yū Hakusho) is a Japanese manga series written and illustrated by Yoshihiro Togashi. The series tells the story of Yusuke Urameshi, a teenage delinquent who is struck and killed by a car while attempting to save a child’s life. After a number of tests presented to him by Koenma, the son of the ruler of the afterlife Underworld, Yusuke is revived and appointed the title of “Underworld Detective”, with which he must investigate various cases involving demons and apparitions in the human world. The Yu Yu Hakusho manga becomes more focused on martial arts battles and tournaments as it progresses.
Yusuke dies while saving another. For such noble sacrifice he is given a second chance at life, but it’s to be a life far different than the one left behind. Now a Spirit Detective, the young man must track down demons and humans alike who desire to rule over the three realms of reality. Granted with amazing new powers to be used in the cause of good versus evil, Yusuke sets out on his first assignment. He will gather together those who will fight alongside him: Kuwabara, Yusuke’s intellectually challenged formal rival from high school; Kurama, an infamous thief from the Demon World who inhabits a human body; and Hiei, a hot-headed demon skilled with both the sword and the third eye. Together, these four set forth to do battle with monsters, beasts and men.
