Crunchyroll streams both previous seasons of To Your Eternity. The series is described as such:
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.
