Fushigi no Umi no Nadia

Synopsis

Nadia rudely awakens Jean and Marie and takes charge, naming their new home "Lincoln Island" after the president of the same name. Then she abandons them and declares to “live with nature in the forest.” Unfortunately, surviving against nature without the benefits of Jean’s technology proves to be much more difficult than she expects. Indeed, her only method of finding food is to steal rations the children have taken from Nemo's cabin. Nadia almost drowns when she attempts to reclaim a hologram from Nemo's cabin, but Jean and Marie rescue her. Nadia is furious at both of them, however, because they have caught fish (she would rather have been saved by them). Marie calls Nadia out for her stubbornness, declaring they all would have starved to death otherwise.
