After 100 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. Those that do make it to safety find a harsh life waiting for them, however.

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

Annie proves her skill in a sparring session, Jan dreams of serving alongside the King, and graduation day brings shocking revelations - along with a sudden outbreak of violence.

The Colossal Titan appears, and a horde of titans after him. Reluctant to repeat the story of Shiganshina, Eren and the scouts are determined to fight for Trost, unaware that this isn't as easy as they might have thought.

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.

Cornered by the titans and out of gas, the desperation takes over the scouts. After hearing the news about Armin's squad, Mikasa encourages her mates in order to continue fighting at any cost.

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.

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 monster and how he ended up humankind's enemy. One question is all that matters: is Eren human or Titan?

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 created 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 manages to get another Maneuver Gear from a dead soldier and escape thanks to Annie, Connie, and Marco distracting the Titans. With Titan Eren now carrying the boulder towards the gate, Ian orders everyone to distract the Titans away from Eren, with some of them sacrificing their lives. Eren finally blocks the open gate with the boulder, and Rico fires a yellow...

A special military tribunal will decide Eren's fate. The Military Police calls for his execution while the Scout Regiment argues that he is a powerful resource for humankind, and Mikasa is put on the spot when asked about the events of the Trost mission.

The Scout Regiment moves Eren to an old abandoned castle where he will continue his training. Hanzi 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 corps they'll be joining, but after the harrowing events in the Trost attack, many are uncertain which branch to choose.

As the Scout Regiment pushes toward Shiganshina, they encounter an intelligent 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 tears its way through the Scout Regiment, 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?

A memory of Eren testing out his Titan powers sheds light on how his abilities work. As the Female Titan slaughters members of the Scout Regiment, Eren is faced with a difficult decision: does he trust his teammates or act out on his own?

The Female Titan has been captured-Erwin's goal is to find out who the human is lurking inside it. Meanwhile, the Scouts realize the reason Levi told no one about their true mission outside the wall is because of a spy among their ranks.

Managing to get out of Erwin's trap, the Female Titan transforms once more and chases after Levi's squad, who fight back in a deadly clash.

After watching Eren get swallowed by the Female Titan, Mikasa and Levi follow the monster in the hopes that he's still alive inside her. As the Scout Regiment tries to recover from the brutal losses of the operation, emotions run high.

After the failed scouting expedition, Eren and his superiors are summoned to the capital. Annie sees just how deep corruption runs in the Military Police and agrees to join Armin in a plot to defy the government-but nothing is as it seems.

When the identity of the Female Titan is finally revealed, she goes on a rampage within Wall Sina. Eren is hesitant to fight her, but Armin and Mikasa throw themselves into the battle in a desperate attempt to stop the towering monster.

A final battle between Eren and The Female Titan breaks out in the Stonhess District, and Eren's rage reaches new heights.
