The internet is full of rumors about the Neet and Hikikomori genius
gamer siblings Sora and Shiro. The two go as far as to refer to the
world as a "shit game", but then one day a young man calling himself
"God" summons them to a parallel universe. There, God has forbidden war,
and "everything is to be settled with games". Yes, even the national
borders. Driven into a corner by other species, the 'human species' is
down to its last city. Can Sora and Shiro, these related failures of
society, become the saviors of humankind in this parallel world?
