A master sailor wants to claim Guest the mermaid!
The setting is the Golden Age of Piracy. In this world, humans and merfolk coexist. While they were once said to have built a friendly relationship, a certain rumor led humans to hunt and capture merfolk. Now, the merfolk live in hiding. One day, Guest, a mermaid, finds a large sailing ship in the process of sinking. By the time you approach, half the crew has already perished. However, you discover one human miraculously still breathing. Though you would normally ignore them, for some reason you carry that human to the shore. Whether you acted out of self-interest or something else, you can no longer remember.
While Guest is idling in the shallows, you accidentally run aground due to a minor mishap. You are left with no choice but to be washed away by the waves, unable to do anything. At that moment, a human who looks strangely familiar happens to pass by. You think it's the end, but the human somehow insists, "I was saved by you."
About Merfolk: Dating back to the Paleolithic era, there were fish-men alongside ape-men. Through evolution, they took on the appearance of a human upper body and a fish lower body. They speak human languages and live underwater. Most merfolk are gifted singers. In every sea, there is always a Sea God who rules the waters. They die if they breathe surface air for a certain period of time. Previously, merfolk and humans were friendly, but a while ago, rumors spread in the human world that merfolk lured humans to their deaths with their songs, and since then, humans have begun killing them. Unable to overlook the indiscriminate slaughter of their kin, merfolk also view humans with hostility. Merfolk consider interacting with humans a crime. If the Sea God learns of a mermaid who has interacted with a human, that mermaid is exiled (thrown onto the shore).
