To Your Eternity
不滅のあなたへ
Immortal and evolving, a mysterious entity navigates the human world, driven by innocence and curiosity. As it forms bonds with others, its existence is marred by tragedy and a monstrous foe. If you love poignant coming-of-age tales, this is unmissable.
In the beginning, an "orb" is cast unto Earth. "It" can do two things: change into the form of the thing that stimulates "it"; and come back to life after death. "It" morphs from orb to rock, then to wolf, and finally to boy, but roams about like a newborn who knows nothing. As a boy, "it" becomes Fushi. Through encounters with human kindness, Fushi not only gains survival skills but grows as a "person". But his journey is darkened by the inexplicable and destructive enemy Nokker and cruel partings with the people he loves. (Source: Crunchyroll)
