The first 2019 issue of Akita Shoten's Weekly Shōnen Champion announced on Thursday that Hiroshi Takahashi's Worst manga will get a new spinoff manga beginning in the seventh issue on January 17. The manga is titled Worst Gaiden: Guriko (Worst Side Story: Guriko), and Ryūta Suzuki is drawing the series. Guriko is a character from the original manga.
Takahashi began the original manga as a continuation of his earlier Crows series in 2001, and ended it with 33 compiled volumes in 2013. The story follows a delinquent named Hana Tsukishima as he rises to the top of the gangs at the notorious Suzuran Boys' High School. A single-volume side story titled Worst Gaiden ran in Monthly Shōnen Champion in 2009.
Digital Manga Publishing published the beginning of the manga in North America in 2004.
Takahashi's Crows manga ran for 26 volumes, and inspired a two-episode anime OVA adaptation. The manga also inspired three live-action films, with Takashi Miike directing the first two films, Crows Zero and Crows Zero II. Crows Explode, the third film, opened in Japan in April 2014. Tokyo Shock released the first film on DVD and Blu-ray Disc in North America, and video label MVM released both Crows Zero and Crows Zero II in the United Kingdom.
