Fist of the Blue Sky launched in the debut issue of Shinchosha’s Weekly Comic Bunch magazine in May 2001 and continued until the magazine ceased publication in August 2010.
However, the anime’s site only notes that the anime will be a new adaptation of Fist of the Blue Sky in general.
Fist of the Blue Sky inspired a 26-episode television anime adaptation in 2006.
The official website for the new television anime based on Buronson, Nobuhiko Horie, and Tetsuo Hara’s Souten no Ken (Fist of the Blue Sky) manga revealed the anime’s title as Souten no Ken Regenesis on Wednesday.
