Hajime Isayama wrote and illustrated the Attack on Titan manga, which was serialized in Kodansha’s Bessatsu Shonen Magazine from September 2009 to April 2021. Its chapters were compiled into 34 volumes. The TV anime adaptation was animated by WIT Studio for the first 3 seasons, after which MAPPA took over. The anime ran for a total of 94 episodes, with the final episodes (88-94) streamed as the two Final Chapters specials.
The Final Chapters were compiled into the THE LAST ATTACK movie with improved visuals and sound.
