Ending animation
At dusk, a child Mikasa Ackermann, wearing her red scarf, is framed from behind glancing at a lake, the moon reflecting on the water. Still clothed, she dives in in a standing position, her eyes closed. After the screen fades to black, a tree of light rapidly grows. The screen fades briefly to the blossoming branches of an actual tree, before fading once again, this time to a close-up on Mikasa's face, barely half of it above the water surface. As the camera zooms out, the blossomed trees on the water around her become visible, while the flowers' petals float through the air.

A fence is framed from below. In front of it are roses, and on top of it are white birds. One of them has a rose in its beak. It soars in the sky, the rest of the flock following suit, as a now adult Mikasa watches the scene.

The shadows of two children is projected onto a yellow meadow. The shortest of the two figures puts their head on the other's shoulder. The camera then cuts to the hands of Mikasa delicately holding a dandelion, and then closing.

Child Mikasa, sat on the meadow, is helped up by Eren Jaeger, also a child. The two share a tender moment touching foreheads, the sunlight trickling through the tree branches above them.

Adult Mikasa wakes up teary-eyed on the meadow. Looking on her side, she sees her hand being held by someone. Where the two hands touch is a butterfly that proceeds to fly away. The screen then fades to white.
