Armin tries to cope with the loss of his friends and allies after Titans massacre his squad. Elsewhere in the city, Mikasa manages to take out several of the monsters, which brings back tragic memories of her past and the first time she met Eren.

A miraculous return is met with anger and fear. Cannons are fixed on Eren as he struggles to remember what happened to him inside the belly of a Titan and how he ended up as humankind's enemy. One question is all that matters: is Eren human or Titan?

The plan to reclaim Trost falls apart when Eren's newfound powers turn him into a mindless giant. As Titans continue to swarm the city, it's up to Armin and Mikasa to make sure the cadets massacred during the mission haven't died in vain.

The Recon Corps moves Eren to an old abandoned castle where he will continue his training. Hange visits and reveals that she's been putting two captured Titans through a series of tests and trials — experiments that she wants Eren's help with.

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.

As the Female Titan continues to tear its way through the Recon Corps, Levi makes a bold decision to split the ranks and send Eren and the supply wagons through a huge forest. Is his strategy genius, or does it spell certain death for the scouts?

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.

With the identity of the Female Titan now revealed, Eren has reservations about fighting her. Mikasa, Armin, and the rest of the Recon Corps try to fight the Female Titan, hoping to distract her long enough to buy Eren time to come to terms with his feelings.

Eren, spurred on by his promise to kill every single Titan, unleashes the full power of his Titan form in the fight with the Female Titan. As their bloody battle draws to a close, it seems humanity may finally have a chance at survival. However, with many mysteries still left unsolved, what will await Eren, Mikasa, and Armin?

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?

The pursuit begins as the Recon Corps battles their way to Eren. But as the Scouts start to take numerous casualties, Erwin executes a risky strategy.

The battle continues as Eren and the Scouts face many hard decisions. Who is the real enemy? What is the war really about? And what will the future hold for mankind?

After barely surviving Eren's recovery, a rising threat from the shadows puts everyone's lives in danger again.

The Scouts take a stand against a new enemy, but it's not just Titans they'll be fighting anymore.
