Yu Yu Hakusho (In Japanese Yū Yū Hakusho, translated in English as Yu Yu Hakusho, Ghost Files, Ghost Fighter) is a Japanese manga series written and illustrated by Yoshihiro Togashi.
YuYu Hakusho has been well received since its debut, with the manga selling over 49 million copies in Japan alone and winning the prestigious Shogakukan Manga Award for shōnen manga in 1993.
The Yu Yu Hakusho manga series was written and drawn by Togashi and originally serialized by Shueisha in the Japanese magazine Weekly Shōnen Jump from December 1990 to July 1994. The manga consists of 175 chapters spanning 19 tankōbon with the first one being released on April 10, 1991, and the last one released on December 12, 1994. Between August 4, 2004, and March 4, 2005, Shueisha released the kanzenban (complete) editions of the manga.
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 manga becomes more focused on martial arts battles and tournaments as it progresses. Togashi began creating Yu Yu Hakusho around November 1990, basing the series on his interests in the occult and horror films and an influence of Buddhist mythology.
