The September issue of Shogakukan’s Monthly Hero’s Magazine revealed on Tuesday that the planned television anime adaptation of Toshiki Inoue, Osamu Kine, and Keita Amamiya’s Sword Gai manga will now premiere on Netflix worldwide simultaneously in spring 2018.
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 magazine did not reveal whether Sword Gai The Animation would be a film, but it did not indicate that it would be a series.
The manga began serializing in the December 2012 issue of Monthly Hero’s Magazine, and ended in October 2015.
