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.

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?

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 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.

Everyone is a suspect in the investigation to find out who killed the two test-subject Titans. Meanwhile, the cadets pick which military branch they'll be joining, but after the harrowing events in the Trost attack, many are uncertain which branch to choose.

As Marley battles the Mid-East Alliance to end a four-year war, a group of Warrior candidates on the front lines compete to be the successor of the Armored Titan.

Though glad the war is over, both the Eldian Warriors and Marley brass realize that neither have a future unless they finish the job of retaking the Founding Titan.

While Willy Tybur reveals the truth in a shocking speech to the world, tensions rise behind the stage as Eren and Reiner meet face to face.

Eren's rampage is thwarted by the War Hammer Titan whose tenacity leaves him stumped. With Marley's military joining the fight, he'll be hard-pressed to survive on his own.

The forces of Paradis begin their assault, but the Warriors stand their ground. As Marley troops close in around them, Eren struggles to break the War Hammer's defenses.

With no Titans left to threaten their escape, the Scouts retreat on the airship. Determined to make them pay for trampling on her home, Gabi chases after with gun in hand.

While Hange and Pixis piece together Zeke's true intentions, tension builds outside HQ where Armin and Mikasa plead for permission to speak with Eren.

Gabi and Falco seek out a fellow Marleyan who's surprised to see Warrior candidates. The truth of what happened at Ragako may shed some light on Zeke's secret plans.

Armin and Mikasa speak with Eren, but are astounded by what he says. In the forest, Levi considers feeding the Beast Titan to someone new, but Zeke has other plans in mind.

A look into Zeke's past shows his struggle to become a Warrior. His plans to end the suffering of all Eldians stems from a chance friendship made in his youth.

With the Yeagerists now in charge, Zeke's master plan is revealed. But before it is put in motion, Eren recruits help to flush out any invaders in their midst.

Caught off guard by Marley's surprise attack, Eren fends off their Titans alone. As the battle rages on above, the Scouts consider Eren's motives from the underground dungeons.

The Beast Titan joins the fray, but General Magath is determined to take him down. Meanwhile, with the city in flames, Colt and Gabi rush to rescue Falco who's held captive by the Yeagerists.

Colt pleads with Zeke to not use his scream and turn Falco into a Titan. All the while, soldiers and Titans clash in battle as Eren struggles to make contact with his brother.

Zeke takes Eren through Grisha's memories to show him how he's been brainwashed. But in doing so, Zeke discovers something about Eren that he never knew.

For 2,000 years, the Founder Ymir has been waiting--a slave to those with royal blood. However, Eren's yearning for freedom gives her a choice that could shake things up.

With no walls left on the island and Shiganshina full of Titans, the Scouts must battle their former comrades. In the midst of it all, Gabi is determined to find and rescue Falco at whatever cost.

Deep in the forest, an unlikely rabble of Marley stragglers and island fugitives attempt to set their hatred aside and talk around a campfire without killing each other.

The Azumabito's flying boat is guarded by a port full of Jaegerists, but the Scouts are reluctant to kill their former friends. If they wish to avoid bloodshed, they can't afford their plan to go wrong.

For the flying boat to take off, the mechanics need half a day to service it. Knowing they'll never last that long with Jaegerist reinforcements on the way, the crew is forced to change their plans.

Regardless of where it all began, Eren commits to his path of destruction during the Scouts' first visit to the Marleyan mainland, leaving Mikasa to wonder if things could've been different.

As the rumbling advances, the remaining members of the Scout Regiment race against the clock with their Marleyan and Azumabito allies to catch up to Eren and stop the rumbling before the rest of the world is crushed under the Wall Titans' feet.

Eren, as the Founding Titan, advances on Fort Salta with countless other Titans. Appearing before the refugees, who stand on the brink of despair, are Mikasa, Armin, Jean, Conny, Reiner, Pieck, and Levi, who narrowly escaped from the rumbling. The battle between former comrades and childhood friends with Eren concludes here.
