Plot
The series follows the story of Eren Jager, a boy who lives in the town of Shiganshina, his adopted sister, Mikasa Ackerman, and their friend Armin Arlert. They live in a civilization surrounded by three circular walls. Over one hundred years ago, humanity was driven to the brink of extinction after the appearance of humanoid giants called Titans, who attack and eat humans on sight. According to what is known, the civilization within the walls is the last surviving remainder of humanity. Their civilization is surrounded by three circular walls called Wall Maria, Wall Rose, and Wall Sina. In the year 845, the outermost wall (Wall Maria) is breached by two new types of Titans, the Colossal Titan and the Armored Titan. This leads other titans to infiltrate the outermost areas of civilization and begin slaughtering its inhabitants. During this incident, Eren's mother is eaten by a Titan, and Eren swears revenge against all Titans. Eren enlists in the military and is also accompanied by his childhood friends Mikasa and Armin.
Five years after Shiganshina's fall, the Colossal Titan appears and attacks the city of Trost, located on the second innermost wall (Wall Rose). Eren helps to successfully defend the city after he discovers that he has the mysterious ability to turn himself into a sentient Titan at will. He additionally regains some memories of his father shortly after the fall of Wall Maria, telling him that the truth about their world can be found in their basement in Shiganshina. These events draw the attention of the Survey Corps and their commander, Erwin Smith, who intends to use Eren's power to reclaim Wall Maria and reach the Yeagers' basement to find the truth about the Titans. Eren, Mikasa, and Armin are transferred to the Special Operations Squad, under the care of Levi Ackerman and Hange Zoe.
Eren joins his companions to fight and protect what remains of humanity while he also looks for the answers to the mysteries surrounding the Titans, the Walls, as well as his father's mysterious disappearance.
