Attack on Titan (2013–2023)
Based on Hajime Isayama’s manga, Attack on Titan is set in a world where humanity lives behind massive walls to protect itself from Titans—mysterious, man-eating giants that threaten human survival. The series follows Eren Yeager, Mikasa Ackerman and Armin Arlert as they join the military and uncover the political, historical and ideological forces shaping their society. Combining large-scale animated action, dark fantasy and horror, the story expands from humanity’s fight against the Titans into a wider conflict about freedom, identity, warfare and the cycle of violence.
