To Your Eternity Season 3 | Official Trailer | Crunchyroll

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, as well as cruel partings with the people he loves.
