Event Year: 2013

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

Utgard Castle comes crumbling down as Ymir desperately battles the Titans. Now, Christa must fulfill the promise they made long ago during winter training.

Without a way to pursue the Titans, the Scouts have no choice but to recuperate as they wait for reinforcements. But do they still have faith in Eren?

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