Ending animation
A young Eren, wearing his red scarf, walks across a field of white flowers. His scarf unwraps itself and transforms into a bird, who soars through the clouds and starry sky.

However, dark clouds emerge and surround the bird, eventually turning into a bird cage. The bird dissipates into stars, which fall on Eren, who is trapped in the cage. To the child's wonder, the cage disappears, and Eren is surrounded by a field with blooming flowers. Various locales in Paradis Island, including Trost District and Utgard Castle, are seen as dilapidated and seemingly abandoned ruins overtaken by nature.

A now adult Eren walks forward freely in this field. He is enveloped in a flame of various colors, and as he turns to face the camera, he vanishes.
