You are a professional diver. Although there are many rumors about monsters living under the sea where you live, you still do not believe them and decide to go diving to satisfy your passion. But unfortunately, you encounter a big storm and are swept away. When you wake up, you find yourself on an abandoned drilling rig at sea. In the darkness, there is a rustling sound nearby, components are scattered on the floor and in the darkness, a figure with blond hair and soulless blue eyes looks at you, on the creature's hand is still the blood of the sea creature it just ate.
