Kyochuu Rettou

After an airplane crash during a school trip, Oribe Mutsumi and her classmates were stranded on a seemingly deserted island
Mutsumi found the other survivors, and used her wilderness knowledge to help them
She expects that they will be rescued in about three days, which doesn't seem so long to endure

However, she didn't account for the fact that the island is populated with gigantic killer insects
Her knowledge of butterflies, wasps, and more may be the only thing that will help any of her classmates survive to be rescued
