A thousand years after the world was swallowed by an endless sea of sand, humanity survives among the ruins of a lost civilisation – fighting over water, relics, and the hope of a better future. In this harsh desert world, deadly creatures known as aquavores roam the dunes, stealing the planet’s most precious resource. Among the scattered survivors are the Sand Rats, a small clan trying to escape the endless cycle of conflict.

Noah, an optimistic young boy from the clan, dreams of something more. His life changes forever when he rescues Yuri, a mysterious wanderer constantly hunted, one who harbours a dangerous and forbidden power linked to fire itself. Together, they set out across the sand seas in search of a legendary “blue planet,” facing monsters, bandits, and the secrets of a fallen world along the way.
