Two and a half years have passed since the Rainbow Rain poured down. The island is undergoing change, driven by the efforts of the young people, with Akaza at the forefront. There are only women among the White. And so, the wedding of Olympia, a rare and precious White, is eagerly anticipated. She too has no doubt that she will be united with her soulmate. One day, an Outsider washes ashore on Tennyo Island, a man with hair colour that is a sign of the White. Even though his life was already over, he looked as if he were sleeping. The next day, he woke up. He had certainly faced "death", but it was as if it had been a daydream. This man, who should not exist in this world, began to unravel the "curse" of the island's inhabitants. Why did the sea let him through? What will his presence bring to the island?
