Kai and her twin sister, Kishi, are skilled pearl divers, but while Kishi has earned her diving cap, Kai must patiently follow her mother's guidance to earn hers. As they compete to gather pearls, Kishi is taken by the ghost whale when she goes back for one more. Determined to rescue her sister, Kai strikes a deal with the Dragon King. She embarks on a journey to Sky Mountain to retrieve a pearl from a fox, encountering bandits and a warlord along the way. Japanese mythology enriches the narrative as Kai navigates challenges to save her sister.
