Manga creator Tadadi Tamori announced on October 27 that the Sword Art Online Alternative Gun Gale Online manga will end in three chapters, and the manga’s fourth volume will be the final volume.
The manga is based on Keiichi Sigsawa and Kouhaku Kuroboshi’s novel series of the same name, itself a spinoff of Reki Kawahara’s Sword Art Online series.
Tamori explained that the manga was originally supposed to end with three volumes, but it ended up becoming four volume.
The novels inspired a television anime adaptation in April 2018, and Aniplex of America streamed the series on Crunchyroll and Hulu as it aired.
