At a strange inn, Maru and Kiruko sink into a drowsy slumber. They awaken to something monstrous under the faint light of the moon. At the nursery, Tokio becomes more suspicious of the world around him. Meanwhile, Shiro receives an unexpected message.

Tokio is taken to see some bizarre-looking babies, and realizes just how little he understands about his surroundings. On a boat with no escape, Maru and Kiruko suffer a terrifying attack. As all is failing, it is up to Kiruko to devise a new strategy.

Maru and Kiruko return to Tokyo to find a neighborhood crowded with tents. When Maru goes off to a game center, Kiruko is left to gather information for herself, and hears a scary rumor.

Maru and Kiruko head to the Ibaraki facility after Juichi gives them his car. Meanwhile, a group of new 5th years join the academy. Mimihime notices that one child called Ohma seems very lonely, and tries to make friends. But Ohma has special reasons for keeping away from the other children.

Maru and Kiruko arrive in a prosperous marketplace. It's the town where the rumored Ministry of Reconstruction runs things. Meanwhile, the academy is suddenly under attack. While trying to take shelter, the children find a hole in the wall.

Mimihime, Shiro, Anzu and Taka all head outside through a hole in the wall, as they search for an answer to their teacher's test. Meanwhile, Kiruko is in tears after Robin does something terrible.
