The story is set in a world where humans are on the brink of extinction due to the sudden appearance of giant humanoid creatures known as "Titans." These creatures devour humans without reason or explanation. The remaining humans live in a walled city, protected from the Titans by a series of concentric walls.
The story follows three friends, Eren, Mikasa, and Armin, who are curious about the outside world and decide to explore. They soon discover that the walls are not as secure as they thought, and a massive Titan appears, destroying a section of the wall and allowing smaller Titans to enter the city.
As the city descends into chaos, the three friends find themselves separated and fighting for survival. They soon learn that the Titans have a weak point at the base of their necks and that humans have developed a way to exploit this weakness.
The story then jumps forward two years, where Eren and his friends have joined the military to fight against the Titans. They embark on a mission to reclaim the outer walls and encounter a mysterious female warrior who is revealed to be Mikasa.
Throughout the story, Eren struggles with his own personal demons and feelings of guilt and regret. He becomes determined to save humanity from the Titans, even if it means sacrificing himself.
The story ends on a cliffhanger, with Eren and Mikasa facing off against a new, more powerful Titan that appears to have a strange and terrifying ability.
