Despite losing countless lives in the battle against the Titans, what’s left of the Survey Corps arrives at the doorstep of Eren’s family home. There, in the basement, they find three notebooks that explain at last the origins of their walled world. In the notebooks, Eren’s father recounts a strange childhood and an even darker history: 1,800 years ago, one woman obtained the power of the Titans, provoking a racial conflict that ripped humanity apart. The Survey Corps realizes that they have been fumbling around in the dark...but what will they do now that they know the horrific truth?
