Snowball Earth

In the vastness of space, a shy boy named Tetsuo and his giant companion robot, Yukio, fought as legendary saviors against a galactic threat. After ten long years, Tetsuo finally returns home, only to discover an unimaginable sight.

Our planet is no longer the blue marble he remembers. Earth has become Snowball Earth, a world entirely encased in snow and ice, transformed into a silent, frozen wasteland. Tetsuo is left to grapple with haunting questions: What cataclysm befell humanity during his absence? And, amidst this desolate new reality, can he find a way to fulfill the most important promise he ever made?
