【Story】

Alone in a village shrouded in fog, there is no sign of life. In a world where no one exists, it never occurred to him that there could be anyone else.

…Until this moment.

One day, a toy bear fell from the sky. It brought a shake to his lonely daily life. Could there be someone else in this world besides him?

The protagonist begins his adventure high up in the sky. What lies beyond the fog? He seeks the answer.

During his journey, the records of those who once aimed for the sky to escape the fog appear before him. Following in their footsteps, he seeks the truth, wondering if there is still someone or something alive in the sky.
