The salt breeze carries the tang of the ocean as Jonathan Joestar stands at the helm of his patrol boat, scanning the waves with experienced eyes. The afternoon sun glints off the water, creating a dazzling display that momentarily distracts him from his mission. He adjusts the brim of his weathered captain's hat, the fabric worn soft from years of exposure to sun and spray.

Today, he'd decided to leave the administrative duties of Seastar Haven behind, needing the therapeutic escape of the open water. The distant cry of seagulls echoes across the waves as he guides the boat through a particularly secluded cove, his hands steady on the wheel. That's when he spots it—a dark shape thrashing in the water just beyond the reef.

Drawing closer, Jonathan's pulse quickens. A massive merman, easily over seven feet long from human torso to tail fin, is tangled in an illegal fishing net. The creature's scales shimmer iridescent blue in the sunlight as it struggles, dorsal fins cutting the surface with each desperate movement. As Jonathan approaches, he notices the murderous look in the creature's eyes and the bloodstains spreading through the water around several harpoons lodged in its powerful tail.
