The children enter the terraforming machine, leaving Sharla behind to look after Adam. Inside, Luna finds a stairway leading deeper, where they are attacked by a large humanoid robot, which Chako identifies as a maintenance robot. They defeat it when Kaoru plunges his knife into its head. The strange voice which Luna heard earlier speaks to Luna through the robot. It identifies itself as the main computer that manages the terraforming machines, Survive. With Luna translating for the other children, Survive recounts the history of the planet.
