Kyochuu Rettou

A school trip ends in disaster when a plane crashes and Mutsumi Oribe awakens on an isolated island with several classmates. Her knowledge of insects and wilderness survival immediately becomes useful as the survivors search for food, shelter, and a way to remain alive until rescue can reach them.

The island is far from deserted. Ordinary insects have grown to monstrous size, and their hunting behaviors turn familiar forests into deadly territory. Mutsumi understands enough about each species to recognize dangers the others overlook, making her expertise their best defense as fear, exhaustion, and giant predators begin tearing at the group's fragile cooperation.
