Oribe Mutsumi and her friends were trapped on an apparently desolate island following an airplane disaster during a school trip. Mutsumi discovered the other survivors and assisted them with her wilderness skills. She anticipates that they will be rescued in three days, which does not appear to be a long time. She didn't, however, factor for the fact that the island is teeming with enormous deadly insects. Her expertise of butterflies, wasps, and other insects might be the only thing that saves any of her students!
