Are you in trouble?

Yu Onijima (dubbed by Mao Ichimichi), who has learned many survival skills from his father since he was a child, and Asuka Suzumori (voiced by Hiyori Kono), a super sports girl who also participated in the track and field club and basketball club Mutsut Amaya (dubbed by Kiseno Anno), who has a high IQ and the appearance of a good student, but is actually a super rotten girl (dubbed by Anno Kiseno), Kujo Shion (dubbed by Waki Anmi), the eldest daughter with an arrogant personality and a sharp tongue, but really wants to be recognized and liked by everyone. In a plane crash, these four female high school students became survivors and drifted to an uninhabited island. How should high school students, who have always sat in class and studied book knowledge, deal with the extremely harsh and extreme conditions on the island? Soon they will know that if they want to survive within the laws of nature, they have to give up a lot of things.
