Ogura is assigned to join the DOGOO's Second Platoon which Newton, Gandhi, and Jack are in. She visits Second Platoon’s headquarters, Alex Rogan. Sio learns that once her E-Gene awakens her personality changes. Sio is sent to destroy an EIO because its armor cannot be breach by EU weapons except by Sio’s pinpoint sniping. Vidocq makes a major discovery about the EIO that shocks the crew. Once an EIO dies, it releases thousands of little EIO with memories from its previous body. Since they can’t be digested, they stay inside animals that eat them, going up in the food chain. Then they create new bodies, taking into accounts of their predecessors’ failures.
