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 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.

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.
