It, a mysterious immortal entity, is dispatched to Earth devoid of emotions or identity. Nevertheless, It can assume the shapes of those nearby who possess a strong drive. Initially, It is a sphere. Subsequently, It mimics the form of a rock. As the temperature falls and snow accumulates on the moss, It adopts the moss. When a wounded, solitary wolf limps past and lies down to die, It takes on the animal's form. Finally, It gains consciousness and begins to cross the barren tundra until It encounters a boy. The boy resides alone in a ghost town, which the adults abandoned long ago in pursuit of the paradise rumored to exist far beyond the endless white tundra. However, their efforts proved futile, and now the boy is in a critical condition. Assuming the boy's form, It embarks on an endless journey, seeking new experiences, locations, and people.
