YuYu Hakusho (Japanese: 幽☆遊☆白書, Hepburn: Yū Yū Hakusho) is a Japanese manga series written and illustrated by Yoshihiro Togashi. It 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, Yusuke is revived and appointed the title of "Underworld Detective". With this title he must investigate various cases involving demons and apparitions in the Human World, with the manga gradually becoming more focused on martial arts battles and tournaments as it progresses. Togashi began creating YuYu Hakusho around November 1990, basing the series on his interests in the occult and horror films and an influence of Buddhist mythology.
The manga was originally serialized in Shueisha's shōnen manga magazine Weekly Shōnen Jump from December 1990 to July 1994. It consists of 175 chapters collected in 19 tankōbon volumes.
