Cromartie High School (魁!!クロマティ高校, Sakigake!! Kuromati Kōkō, lit. "Forging Valiantly Ahead!! Cromartie High School") by Eiji Nonaka, is a Japanese comedy manga, which was adapted into an anime and a 2005 live-action movie titled Cromartie High – The Movie directed by Yūdai Yamaguchi. Both the manga and anime have been released in North America by ADV Manga and ADV Films respectively. However, the manga is not yet completely published in North America due to restructuring issues at ADV. Discotek Media has since licensed the anime, after ADV's closing in 2009. The manga won the 2002 Kodansha Manga Award for shōnen. The series aired in the United States on the cable network G4 on its Barbed Wire Biscuit late-night block and on the UK satellite channel Rockworld TV.
It follows the everyday life of Takashi Kamiyama and his odd classmates at Cromartie High School, an infamous school for delinquents.
