An Orb, known only as It, is cast to Earth to be observed from afar. Capable of changing forms from beings whose reflections It captures, It first becomes a rock and then, due to the rising temperature, moss. It does not move until one snowy day, a wolf at death's door barely crosses by. When It takes the animal's form, It attains awareness of its consciousness and starts to wander with an unclear destination in mind. Soon, It comes across the wolf's master—a young boy waiting for his tribe to return from a paradise abundant with fish and fruit in the south. Though lonely, the boy still hopes his loved ones remember him and that he’ll reunite with them someday. The boy leaves home with It to find paradise using his tribe’s traces. However, with a heavily injured body and no sight of his elder comrades, what will become of the boy? To Your Eternity illustrates the story of an immortal being experiencing humanity, meeting all types of people in many places throughout time.
