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.

With the Female Titan still chasing after Levi's squad, Eren considers turning himself into his Titan form, but Levi tells him to choose to be either a monster or a member of the Recon Corps. As Eren remembers what he has learned from the squad, he realizes that the danger and sacrifice they all share is not what binds them — it is trust. Now it is up to Eren to make the decision of who he will trust.

With the help of Levi's squad, the Recon Corps has successfully captured the Female Titan. As Commander Erwin and Captain Levi begin preparations to extract whoever is inside the Titan, will the Recon Corps discover its true identity, or does the Female Titan have one last trick up its sleeve?

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?

Hange is insistent on capturing a Titan for the advancement of scientific research, but Erwin is adamant in his refusal to allow it. Will an unexpected discovery during an expedition beyond the walls alter the situation?

Franz and Hannah try to help Eren reconcile with Mikasa after an argument, Mikasa tries to act on her feelings with Eren, and Hange tries to communicate with a Titan.

Levi's group joins the Scout Regiment, but they bring with them a hidden agenda. The upcoming expedition beyond the walls seems like the perfect opportunity to carry out their plan.

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.

With the appearance of Titans within Wall Rose, Sasha and Connie ride as messengers to warn their villages of the impending threat.

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

Following the battle, the Scouts regroup atop the wall only to find more questions than answers.

With a new enemy revealed, Eren and the Scouts fight back using all the techniques at their disposal.

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 Scouts rally and charge in pursuit, but Reiner is not quite himself while the group is trapped in the giant forest until nightfall.

When their group finally flees, Ymir wonders whether she should lie or stay true to herself, even if it means ruining the lives and future of those she cares about.

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.

Historia and Erwin look back on their past, revealing a shady government with a hidden agenda and inspiration for an uprising.

On the run and running out of time, the Scouts must entrust their lives to others if they plan on surviving.

When everything falls apart, Eren must believe in himself to save his friends. But Eren alone may not be enough to stop the impending doom.

Having seen a glimpse of his father's memories, Eren attempts to track down a man hoping they might shed some light on his father's secrets.

Though their Thunder Spears prove effective, the Scouts' celebration is short-lived as disaster descends upon Shiganshina.

While picking up the pieces from the costly battle, tensions rise when deciding which of the wounded Scouts to use the single syringe on.
