After Tet leaves, Sora and Shiro begin their search for more information and a place to stay, taking them to Elkia-Imanity's only remaining kingdom. The mysterious sender turns out to be Tet, who informs them about the world's absolute rules. However, after responding to a message from an unknown user, they are suddenly transported to Disboard.
On Earth, stepsiblings Sora and Shiro are two inseparable shut-ins who dominate various online games under the username 'Blank.' While notorious on the internet, the pair believe that life is merely another dull game. In a place where everything is decided through simple games, humankind seems to have no way out of their predicament-but the arrival of two outsiders poses a change. The lowest of the sixteen-Imanity-consists of humans, a race with no affinity for magic.
Sixteen sentient races inhabit Disboard, a world overseen by Tet, the One True God.
