Nagasarete Airantou

A 14-year-old boy named Ikuto Touhouin gets into a conflict with his father and flees home. He joins a ship traveling overseas, but a severe storm causes it to sink. After drifting at sea for a week, he reaches an island where everyone behaves as if from the Meiji era and is exclusively female. The islanders have had no contact with others, especially males, due to surrounding whirlpools that prevent escape. His arrival introduces the first male presence in their isolated society.
