At the end of the Meiji Restoration, a girl saint was crucified and burnt alive under persecution. A century later, Katori and his six childhood friends are summoned to her world beyond the nirvana, where they receive the Great Commission: build a kingdom, and make disciples of all nations.

As the lowly must obey a higher-up in the hierarchy, can they fight and defeat other nations to conquer the world–before infighting brought up by their own hidden desires breaks them apart?
