Ogura and the others are sent to deal with an Evolutionary Invasion Object that can ride a hurricane.
Weapon otaku Ogura Sio is on a school trip to Taiwan when she and her classmates get caught up in an Evolutionary Invasion Object attack, not that she has any idea what is going on. And who is the guy with the knives?
The incident in Taiwan draws to a close, and Sio gets a chance to have a heart-to-heart with recovering Asao before deciding whether she will join the monster-fighting team or not.
Sio starts intensive training at the Dogoo facility with war photographer Robert Capa. She manages to make some friends on base, but the reality of everyone's situation there is harsh.
