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.

A sudden visit from the Tybur family shakes up the Marleyan military. Meanwhile, Falco smuggles letters for a friend and helps two old comrades reunite.

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.
