In fantasy works, the settings where the characters hail from as often as crucial to the narrative as the characters themselves. Through the Game, a fierce battle for dominance with Walled Tokyo as the battle field, the 23 worlds, each with their own sense of right and wrong competes against one another for their right to shape the multiverse to their ideals.
But while the main 23 worlds perpetuate their battle throughout Walled Tokyo, there are other, smaller worlds that exist out of the 23 that are drawn in to the fate of Walled Tokyo one way or another.
