The official Twitter account for Kodansha’s Bessatsu Shōnen Magazine announced on Wednesday that Hajime Isayama’s Attack on Titan manga now has over 60 million copies in print.
Two of the spinoff manga — Attack on Titan: No Regrets and Attack on Titan: Junior High — received anime adaptations of their own.
Isayama’s Attack on Titan manga depicts the battles between humans and the giants who now rule the world outside humans’ walled enclaves.
The manga inspired a 25-episode television anime series in 2013, with a second season set to premiere in spring 2017.
