Following a plane crash on a school excursion, Oribe Mutsumi and her peers found themselves marooned on what appeared to be an abandoned 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 for everyone Yet she overlooked the presence of enormous lethal insects on the island. Her understanding of butterflies, wasps, and other species might be the sole advantage that enables any of her classmates to endure until help arrives today.
