A thousand years have passed since the world was completely covered by an endless sea of sand. The advanced scientific civilization of the past has perished, and the remaining fragments of humanity struggle to survive against giant, water-stealing creatures known as aqua gorgers or mizuhami, which hoard the planets most precious resource. In this harsh and unforgiving environment, a boy named Noah lives in a remote area with his clan, the Sand Rats, who have chosen to distance themselves from constant conflict by settling at the edge of the known world.

Noahs life changes forever when he rescues a mysterious woman named Yuri who is being chased by the deadly aqua gorgers. She initially appears to be a simple vagrant, but she is in fact an incarnation of the Fire God, a being with the terrifying power to burn anything she touches. Despite the danger she represents, Noah decides to help her, setting the pair on a perilous journey across the vast desert. Their shared goal is to find a legendary paradise known as the Blue Planet, a place that may hold the key to the worlds salvation.

Their adventure pits them against not only the monstrous aquavores but also countless bandits and the lingering secrets of the collapsed civilization buried beneath the sand. Noah represents an optimistic spirit yearning for a better future, while Yuri carries a forbidden and dangerous power connected to the very flames that could destroy what remains of the world. Together, they form an unlikely alliance as they travel toward the end of the sand sea in search of a legend. The complete narrative is structured as a super-classical desert punk fantasy, unfolding over approximately fifteen chapters collected into three volumes, following the pair as they navigate a world where water is life and fire is both a weapon and a curse.
