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.

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

The Scouts search for a hole in the wall while Eren and the others learn that someone close may be hiding all the answers.
