Attack on Titan (Japanese: 進撃の巨人 Hepburn: Shingeki no Kyojin, lit. “The Attack Titan”) is a Japanese manga series both written and illustrated by Hajime Isayama. It is set in a fantasy world where humanity lives within territories surrounded by three enormous walls that protect them from gigantic man-eating humanoids referred to as Titans.
“On that day, mankind received a grim reminder. We lived in fear of the Titans, and were disgraced to live in these cages we called walls.”
Over a century ago, terror rained upon humanity when monstrous giants named “titans” appeared and mercilessly devoured humans. With no other choice, mankind built large walls to barricade themselves safely in and keep the Titans out.
Decades later, Eren Yeager is a boy that has grown up within the walls only knowing peace. He and his friends, Mikasa and Armin, innocently dream of exploring the vast world outside the walls. But none except the military have ever left their safe haven — until the day comes when a colossal titan breaks through the wall, and humanity’s peace is shattered to ruins once again.
