SNOWBALL EARTH

Tetsuo is a timid boy whose only companion is a colossal robot named Yukio. Driven by a quiet vow to one day make a true friend, Tetsuo and Yukio are thrust into an extraordinary role as the saviors of humanity. Together, they wage a grueling war against terrifying galactic monsters descending from the farthest reaches of outer space. Their bond becomes the foundation of Earth’s defense, transforming a shy child and his mechanical guardian into legendary protectors. After ten long years of relentless conflict beyond the stars, the final battle concludes, and Tetsuo finally returns home. However, the world he discovers is unrecognizable. Earth has been transformed into a desolate, frozen wasteland—a catastrophic state known as Snowball Earth. Every continent is buried beneath endless snow and ice, turning the once-thriving planet into a deadly, inhospitable realm. The fate of the human race remains a haunting mystery, leaving Tetsuo to navigate this chilling new reality alone with Yukio. Amidst the ruins of civilization, he must uncover what happened during his absence and confront his most personal challenge yet: fulfilling the promise he made to his giant companion before time runs out.
