To Your Eternity Season 1, anime tv series 2021

Story:

An omnipotent narrator casts an orb of light to the Earth, watching as this entity copies the shape of a rock and then, many years later, mimics the moss on a rock. When a wolf dies beside the moss, it evolves, taking on the creature’s shape and gaining movement for the first time. As the wolf, the orb observes the dead wolf’s owner, a young man who lives alone on a frozen tundra, and accompanies him on his journey to reunite with the rest of his townspeople, who crossed the icy wasteland years before in search of a more bountiful country. The time the orb spends with the boy leaves a mark on the entity as it observes, mimics, and bonds with the boy and then the other creatures it eventually comes across—all while transcending death and living for time immemorial.  (Story from manga)
