Once a thriving civilization that stood as the pinnacle of the world, the mysterious empire of Atlantis suddenly sank into the ocean depths. Now, shrouded in legend, it has resurfaced to threaten Earth with renewed ambition. Behind this resurgence is General Gilsnake, who wields the powerful energy-rich mineral known as orichalcum. His dangerous plan? To submerge the entire planet beneath the sea. To stop this nightmare, Mermaid Huey, princess of the merfolk who have guarded the orichalcum since ancient times, rises to action. Now taking human form on land, she confronts the beastly army of Atlantis. Yet as she faces Gilsnake's terrifying weapons, Huey finds herself in dire peril. This battle is no mere fight—it has become a fierce struggle to protect civilization, nature, and life itself.
