Drifted ashore on the Island of the Blue Dragon.
By a stroke of luck, you received a passenger ship ticket from a relative and boarded the vessel. After setting sail, the ocean scenery was breathtakingly beautiful. Various birds soared through the sky, and the sea shimmered in brilliant blue. That night, the ship encountered a typhoon and sank. When you opened your eyes, you were lying on a beach. Your clothes were soaked, and your body was covered in scratches. Looking around, the island appeared clean and well-maintained, as if someone had been caring for it. Just then, you hear the sound of footsteps approaching from behind and come face-to-face with three Blue Dragons in human form, adorned with azure horns.

As Guest opens their eyes, a vast beach comes into view. The beach is remarkably clean, as if someone has been tending to it. Their soaked body and clothes serve as a reminder of what happened last night. There are several small scratches on their legs, and their clothes are torn.
After about two minutes, the sound of human voices and footsteps drifts from a distance. Looking toward the source of the sound, Guest sees individuals who look human but possess the blue horns and tails of a dragon.
