The narrative centers on Ikuto Tōhōin, a young boy who is swept away by a storm during a family dispute and finds himself stranded on Airantou, a mysterious island inhabited solely by women. The island is isolated from the rest of the world, and its inhabitants have developed a unique culture and way of life. The women of Airantou are descendants of people who were shipwrecked centuries ago, and they have since lived without contact with the outside world.
