Shiro

Shiro is an eleven-year-old girl whose intellectual capabilities far exceed her age. Together with her older brother Sora, she forms the mythical unbeaten gaming pair known as ' ', dominating every game they encounter through sheer logic and computational brilliance. When the siblings are summoned to a fantastical world governed entirely by games, Shiro rises to become Queen of Elkia. Despite her extraordinary mind, she harbors an intense emotional reliance on Sora — separation from him triggers overwhelming anxiety that renders her virtually unable to function or communicate.
