Synopsis
"It", a mysterious and powerful otherworldly orb, is sent to Earth with no sense of self, feelings, sensations, emotions nor identity of its own. However, It is able to take on the shape and form of those around that have a strong impetus. Initially an orb, it imitates the form of a rock. As the temperature drops and snow falls atop the moss, It inherits the moss. When an injured, lone wolf comes limping by and lays down to die, It takes on the form of the animal. Finally, It gains consciousness and begins to traverse the empty tundra until It meets a boy. The boy lives alone in a ghost town, which the adults abandoned long ago in search of the paradise said to exist far beyond the endless sea of white tundra. However, their efforts were for naught, and now the boy is in a critical state. Acquiring the form of the boy, It sets off on a never-ending journey, in search of new experiences, places, and people.

After dying multiple deaths, he is found in a swamp by March, a young girl aspiring to be a caring mother, chosen to be a sacrifice to appease what they believe to be a rampaging bear spirit. She names the boy “Fushi”, and befriends him, teaching him how to eat and become less feral.
