Storyline
In the far future, humans abandon a devastated Earth and travel to outer space. However, due to an unknown phenomenon that prevents them from traveling into space, humanity returns to Earth only to find it inhospitable except for Japan. To accommodate the entire human population, pocket dimensions are created around Japan to house the populace. In order to find a way to return to outer space, the humans begin reenacting human history according to the Holy Book Testament. But in the year 1413 of the Testament Era, the nations of the pocket dimensions invade and conquer Japan, dividing the territory into feudal fiefdoms and forcing the original inhabitants of Japan to leave. It is now the year 1648 of the Testament Era, the refugees of Japan now live in the city ship Musashi, where it constantly travels around Japan while being watched by the Testament Union, the authority that runs the re-enactment of history. However, rumors of an apocalypse and war begins to spread when the Testament stops revealing what happens next after 1648. Taking advantage of this situation, Tori Aoi, head of Musashi Ariadust Academy's Supreme Federation and President of the student council, leads his classmates to use this opportunity to regain their homeland.
