After a disastrous school trip, Homare Onishima, Shion Kujou, Asuka Suzumori, and Mutsu Amatani find themselves stranded on a deserted island. While Shion, Asuka, and Mutsu panic and despair, Homare stays remarkably composed. Her upbringing included extensive survival training with her father around the world, giving her the skills to handle such a situation with ease—from scaling cliffs to setting traps and building shelters. Homare's experiences have prepared her well for surviving on an uninhabited island where rescue seems unlikely.
The real challenge, however, is managing her three anxious companions. As Homare teaches them survival techniques, including consuming fish blood and cicadas, the girls begin to see their predicament differently, realizing that being stranded may not be as terrible as they first thought.
