The Basement

Chikashitsu (地下室)

Armin Arlelt reluctantly comes to grips with the fact that he has eaten Bertholdt Hoover and that he was chosen for survival over Erwin Smith. Half of the remaining soldiers, including Eren Jaeger travel to his family's basement where they discover three journals and a photograph left behind by his father.

The journals detail Grisha's life from beyond the Walls, where humanity has not perished and technology has progressed enough to allow humans to live elegant lives. He learned the truth of his own situation one day when he went out to see an airship along with his sister Fay.
