Event Year: 2013

With a new enemy revealed, Eren and the Scouts fight back using all the techniques at their disposal.

Following the battle, the Scouts regroup atop the wall only to find more questions than answers.

Unarmed and overwhelmed by the Titan assault on the castle, the only hope for the Scouts may lie in a promise and a secret.

Coupled with the military's cover-up of a previous incident, the shocking discovery inside the Walls causes a stir. Elsewhere, while the new Scout recruits are held for observation, a surprising threat appears.
