One of the leading characters in No Game No Life's volume 6, which details the apocalyptic war of old that resulted in Teto assuming the role of the One True God. Her name is also spelled as Schwi.
A 211 year old Ex-Machina, she appears in the Light Novel's 6th volume as well as the anime movie as one of its two protagonists, the other being Riku. It transpires that she originally destroyed his home when he was a child, but their first proper meeting happens when Riku was already an adult. While she is originally expressionless, she eventually learns how to smile, gets married to Riku, yet ultimately sacrifices herself for his gamble. Before this, she explicitly wishes to learn about human procreation, not understanding why this irks Riku greatly.
