Series by 氷坂透

Kasumi, Raika, and Subaru, three 17-year-old female students at a military academy, are sent to an uninhabited tropical island for survival training. Tasked with conducting an ecological survey, the trio—tomboyish Kasumi, airheaded Raika, and level-headed Subaru—begin their mission with enthusiasm but quickly face setbacks. Their first day is marked by mishaps, including accidentally burning down their shelter, along with their map and guidebook. The group’s attempts to adapt to island life lead to a series of comedic blunders as they navigate the challenges of their environment. Their lighthearted, chaotic efforts to complete the mission form the core of their tropical survival adventure.
