But Tenjo and the law of causation collapse by... more>> a war and humans return to the Earth, which has turned into an inhabitable planet except for the Shinshu area. Shinshu is too small to accommodate all the humans, so they duplicate the area and create "Juso Sekai".

They try to resume the history reproduction from A.D.1457, but the update of history terminates in A.D.1648. A rumor of apocalypse begins to spread around the world. <<less
