| Summary | Beneath the waves off Japan’s coast, divers investigating a sunken cargo ship encounter a nightmarish hybrid of iron and flesh—a clawed, fanged creature lurking in the wreckage. Days later, a coastal village boy glimpses a monstrous "iron mermaid" crawling ashore, its metallic scales glinting as it delivers a cryptic warning of impending chaos. In Tokyo, a student entrusted with a sealed iron box becomes entangled in a deadly chase, pursued by shadowy figures and a spectral, iron-scaled beast that invades his home. The box’s contents—a captain’s will and a nautical chart—reveal a decades-old secret: a sunken ship’s cargo of gold bullion worth billions. As salvage crews race to recover the treasure, the enigmatic sea monster resurfaces, stalking their expedition with eerie intelligence. From shadowy forests to moonlit decks, an ancient terror stirs, blurring the line between machine and myth, its motives as unfathomable as the depths it calls home. |
