"It has been two months since the Kantou Incident—the name given to Angelia Avalon’s failed attempt to punch through the walls between dimensions in the Kantou region of Japan.

During the Incident, the Drexler Institute—an organization with ties to demons—began to stir, re-activating various projects in different parts of the world. The Japanese branch of the Drexler Institute was annihilated by the European Celestial Union, but found new life as the Rosenberg Branch of the European Celestial Union.

Soon after the Kantou Incident, large-scale dimensional rifts began to open all across Japan. This sudden uptick in celestial phenomena was seen as exceptionally odd by many, and some even whispered that it could be the result of secret research by the Drexler Institute. The Japanese branch of the Celestial Union was dispatched to investigate the phenomena, and they called on several angels from the National Academy of Metaphysics.

Several angels from the Rosenberg Branch of the Celestial Union were also dispatched, but they were soon intercepted by the Aesir.

Only six days remain until the destruction of Japan. "
