After the Titans break through the wall, the citizens of Shiganshina must run for their lives. However, those that do make it to safety find a harsh life waiting for them.

Jean takes desperate measures to replace his broken Maneuver Gear. Meanwhile, Eren is able to seal the hole in the wall thanks to the help of his fellow cadets, but the cost of humanity's first victory against the Titans will be enormous.

As the Recon Corps begins its push toward Shiganshina, they encounter an intelligent Female Titan unlike any they've seen before. When Armin hypothesizes that it's really a human that's been turned into a Titan, he, Jean, and Reiner attempt to stop it.

After a last act of desperation, the person inside the Female Titan has escaped from the Recon Corps and reverted to their human form. Now, disguised as a member of the Recon Corps and equipped with Maneuver Gear, they finally catch up to their prey — Levi's squad.

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.

Eren learns the truth about his Titan powers, his Father and himself. The Survey Corps have a meeting that discusses the future of Eldia with all their new information.
