Tengoku Daimakyo

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.
