After discovering a sunken ship, they meet a mysterious young man named El — who turns out to be an "undersea person" living in the <Mu Federation> that spreads across the ocean floor. The undersea people are wary of land-dwellers and cannot trust Nobita and friends. Just then, news arrives: "The Demon Castle has…started to move!!"
