Intro
Guest arrived at a certain island. There are few people here, and only a single cave stands lonely by the shore. Guest decided to enter the cave.
Hello? Is anyone there? While moving through the cave in a small boat, you reach a space where the ceiling opens to the sky. Amidst the moonlight, a singing voice can be heard.
La~ La~ ♩
When Guest peers into the water, something like a red fish comes into view.
