The anime adaptation of Toshiki Inoue, Osamu Kine, and Keita Amamiya’s Sword Gai manga premiered with the first 12 episodes worldwide on Netflix on March 23.
A sequel series, titled Sword Gai Evolve and with the same creative staff, launched in Monthly Hero’s Magazine in November 2015, and is currently ongoing.
The manga began serializing in the December 2012 issue of Monthly Hero’s Magazine, and ended in October 2015.
The manga previously inspired a 3D CG promotional video by Digital Frontier (Wolf Children production, Summer Wars 3D graphics) in 2013.
