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.

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.

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.
