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.

Five years ago, in Asakusa, Robin, Haruki and his racer sister Kiriko had spent their days happily living in an orphanage.

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 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.

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 its trail, and meet a mysterious informant along the way. Meanwhile, back at the nursery, an emergency meeting is held.

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 teachers test. Meanwhile, Kiruko is in tears after Robin does something terrible.
