Ending animation
As the credits roll, we watch the Shiganshina District from the view of the tree on the nearby hill. Mikasa Ackermann, Armin Arlelt, Jean Kirschtein, Conny Springer, Reiner Braun, Annie Leonhart, and Pieck Finger visit the grave of Eren Jaeger. Several years pass and Mikasa returns with a husband and child to lay flowers on the grave. More years pass and an aged Mikasa visits again with a larger family. After the last flowers are laid in front of Eren's grave, Mikasa dies peacefully of old age, buried with Eren's scarf, and the tree is left alone for some time.

Time fast-forwards as Shiganshina District goes through an industrial period, growing into a modern city, and then a futuristic landscape. All the while, the tree, untouched by this progression, grows gargantuan in size. Paradis Island soon finds itself in another war. Eren's grave is nearly buried in the tree and surrounded by bullet shells. An unknown time later, the abandoned ruins of the once-futuristic Shiganshina District are bombed into oblivion by an unknown attacker.
