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.

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.

Trapped on the world's most dangerous island, Falco and Gabi will do anything to survive. Elsewhere, the public demands answers when they learn the savior of Paradis has been detained.

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.

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.

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.
