Following a plane crash on a school excursion, Oribe Mutsumi and her classmates became marooned on what appeared to be an empty island. Mutsumi located the remaining survivors and applied her outdoor expertise to assist them. She believes rescue will arrive in roughly three days, a span that seems manageable. Yet she overlooked the presence of enormous lethal insects on the island. Her familiarity with butterflies, wasps, and other arthropods could prove essential for any of her peers to endure until help arrives and hope for survival and remain hopeful.
