Attack on Titan
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 Zoë.
