After one hundred years of peace, humanity is suddenly reminded of the terror of being at the Titans' mercy.

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.

Eren begins his training with the Cadet Corps, but questions about his painful past overwhelm him. When he struggles with a maneuvering exercise, Bertolt and Reiner offer kindly advice.

Five years have passed since the fall of Wall Maria and Eren faces off against the Colossal Titan after it appears out of nowhere once again, and knocks a strategic hole in the gate of Wall Rose. As Titans swarm the city, the newly graduated Cadets are called in to fight a brutal battle that won't be without casualties.

After the retreat bell sounds, many cadets find themselves without enough fuel to scale the wall back to safety. Mikasa begins to lose hope once she hears of the deaths in Armin's squad, but the appearance of a new type of Titan stokes her will to fight.

Cadets respond to Eren's terrifying transformation with doubt and fear as he struggles to understand it himself. If Armin can’t talk the commander into using Eren’s newfound powers for the good of humankind, all hope of stopping the Titans might be lost.

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.

A recap of events since the Fall of Shiganshina and the Battle of Trost.

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?

Unarmed and overwhelmed by the Titan assault on the castle, the only hope for the Scouts may lie in a promise and a secret.

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

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?

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

As battle breaks out to prevent the ritual, Historia makes a shocking decision which leads to catastrophe.

The survey corps and the wall garrison must protect the Orvud District from the impending attack of Rod Reiss' titan.

Against a rush of enemies, the Scouts scramble to defend their horses. But despite falling into a trap, they have their own surprise for the Armored Titan.

As Erwin’s heroic charge buys Levi time to confront the Beast Titan, Armin comes up with a plan of his own that lays it all on the line.

The Scouts reflect on all they have gained and lost in their mission. With their enemies gone, Eren and the Scouts finally enter the basement to uncover the truth that will change everything.
