Sirensia is a land that was once home to sirens and now offers no welcome at all to visitors. A classic RPG Maker horror game built around exploration and adventure, set in an underwater world designed to be accessible to everyone — including those with no particular comfort around the ocean. A teenager exhausted by work and stung by recent failure makes a nostalgic trip back to a place from his past. The trip returns him to childhood memories he had not fully processed and leads him into the most mysterious and consequential adventure of his life.
