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.

Two years pass and the time for the recruits' graduation approaches. Annie proves her skill in a sparring session, Jean dreams of serving alongside the King, and graduation day brings shocking revelations — along with the sudden appearance of an old foe.

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.

Armin comes up with a risky plan that pits Titan against Titan as the abandoned cadets attempt to take back their headquarters. Getting into the building might be possible, but getting out alive and refueled will mean facing more of the giants.

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.

Plans are made to use Eren's Titan powers to seal the hole in the wall in an attempt reclaim Trost. But with the government's bloodstained history and vocal dissenters in the military ranks, the biggest threat to humankind may not be the Titans.

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.

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.

Eren struggles to balance himself on the omni-directional mobility gear, Jean gets lost during training, Marco sneaks into the Girl's Dormitory to return a lost pink bag.

Two years after escaping the torment of his mother, Jean attempts to avoid her when returning to Trost for a training exercise. In a strange turn of events, he ends up in a cooking contest against Sasha.

What begins as a simple training exercise turns into a disaster. A dysfunctional team of cadets must learn to work together after Christa is taken hostage by a group of brigands.

Utgard Castle comes crumbling down as Ymir desperately battles the Titans. Now, Christa must fulfill the promise they made long ago during winter training.

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

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 Annie needs a day off from patrol duty to take care of some personal business, her roommate agrees to cover for her. But only if she does her the favor of searching for a girl who's been reported missing.

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

Reiner reflects on his past, remembering what pushed him to become a Warrior and keep moving forward when all hope was lost.
