On the night of the First Battle of Garreg Mach, a spell intended to remove its victims from the world goes wrong. Instead of being imprisoned in a realm of darkness, those who are caught in its wake find themselves in Tokyo, a land far beyond their imagining and find themselves inexorably drawn into a game that they were never supposed to play. Despite the wonders and terrors of the new world they find themselves in, the shepherds of Fódlan's future must face the coming disaster head on if they have any hopes of returning home and seeing their ambitions through to the end.
