Kingdom Game

Plot
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.

Every midnight, each of them are randomly given a role out of Monarch, Aristocrat, and Plebeian. 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?
