Japan has collapsed after the Great Disaster. Kiruko accepts a request to take a boy named Maru to a place called Heaven. Meanwhile, children live behind the walls of a nursery in luscious green surroundings. After receiving a mysterious message, Tokio begins to doubt the world around him.
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.
Five years ago, in Asakusa, Robin, Haruki and his racer sister Kiriko had spent their days happily living in an orphanage.
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 are on the hunt for the Immortal Order. On the way, they stay at a hotel run by a girl named Totori. Dumping their bags and searching for safe drinking water, they stumble upon a badly injured man.
Maru and Kiruko find what they believe is the doctor and the Immortal Order. Instead, it is a hostile organization that is strongly opposed to the treatment that the Immortal Order provides.
After killing the Man-Eaters, Maru and Kiruko finally meet Dr. Usami. He asks something difficult of them, and leads them both to a room where a horrifying scene awaits.
Maru and Kiruko discover that Dr. Usami had a button with the same pattern as the logo they found on the Kiru-Beam. They decide to follow it's trail, and meet a mysterious informant along the way.
Maru and Kiruko decide to head to the Ibaraki facility of the Takahara Academy. Since it's on the way, they agree to help Juichi confirm whether his baby is still alive.
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.
Maru and Kiruko arrive in a prosperous marketplace. It's the town where the rumored Ministry of Reconstruction runs things.
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.
