Opening animation
The opening begins with a shot of Eren opening his eye, followed by him tying his hair into a bun and putting on his jacket. Mikasa unwraps her scarf from her neck while Armin rests in a prison cell. Eren walks forward, which is immediately juxtaposed with a Wall Titan stomping on a building in a town.

An army of Wall Titans march forward, through a forest, then a town, before we see the full size of the army on the horizon before they trample a city. Eren and Zeke stand opposite of each other to a background of DNA strands and cells under a dark red tint.

Eren morosely walks across a courtyard while white doves fly past him. During a flashback of the 104th Cadet Corps, Marco is watching Sasha reprimand Conny. Jean attempts to flirt with a disinterested Mikasa while Armin watches in amusement. The scene immediately shifts to what remains of the Cadet Corps after the raid of Liberio at Sasha's funeral. Another flashback shows Bertholdt, Reiner, Annie, Ymir, and Historia by a stairwell, before jumping ahead to the future in Liberio. Reiner, Porco, Pieck, Colt, Udo, and Zofia watch as Falco playfully kicks Gabi.

Atop of Wall Maria, Eren again walks forward, with the wall resembling a bridge between the city within the Walls and the outside world. In a darkly-lit room, a blood-stained Levi stands facing upward. In a similar room, Hange brushes aside their hair. With a brief scene of Eren on the Walls, another flashback shows a young Zeke playing baseball with Xaver. Zeke pitching a ball is juxtaposed with the Beast Titan doing the same, before cutting to Zeke in a brightly-lit forest.

Eren bites onto his hand to transform into his Attack Titan form, brawling with the Armored Titan in Paradis. Pieck rests her head on a table, and then the Cart Titan charges forward, presumably where Eren and Reiner are fighting. Porco stands next to a window, whose reflection bears Ymir's image, before the Jaw Titan joins the fight as well. Annie sits among the shards of her crystal prison and exhales through her clasped hands, followed by an image of the Female Titan staring into its palm. Bertholdt within his Colossal Titan form sheds a tear, which drops onto Armin, awakening him. Armin's Colossal Titan stands among the ruins of Liberio. The War Hammer Titan swings its hammer, followed by the Attack Titan grasping Lara Tybur's crystal.

Several images in succession show the world of the Paths in between images of Ymir Fritz sinking in the air. In the real world, Eren stands among the clouds, shifting between his adult self, who stares blankly, and his child self, who looks onto the scenery in awe, juxtaposed with the memory of a younger Eren killing Mikasa's kidnappers. Meanwhile, crowds witness the march of the Wall Titans, running away in panic and fear.

The 104th Cadet Corps stand atop the Walls, silhouetted by the setting sun. In the present, Mikasa, now alone, wraps her scarf around her neck. In the fields of Shiganshina, a young Eren, Armin, and Mikasa run towards the tree on the hill. Soon, Armin and Mikasa disappear, and Eren's child self is replaced with his teenage self, followed by his adult self as "Kruger," staring resolutely at the camera as his eye bears visage of an army of Wall Titans, led by Eren's Founding Titan.

Eren on top of the Walls screams out in anguish. A Wall Titan marches forward, leaving a footprint into the ground. The footprint changes to a normal human footprint, surrounded by flowers and leaving a dead butterfly in its wake.
