Summary
Shiro is an 11-year-old genius NEET and hikikomori gamer who plays alongside her step-brother, Sora, as a member of 『 』, also known as Blank. Born on December 12, she stands at 4'7" (140cm) and weighs 38 kg. Her appearance features white hair at the top that transitions into light blue with yellow and green tips in the light novel, while the anime depicts her hair as white and pale blue with very light sea green tips. She has red eyes with gold pupils and is currently alive. Shiro possesses a genius-level intellect for logic and problem-solving but struggles to comprehend emotions or social behavior, often relying on Sora to help her defeat human opponents like Tet during their chess match. She rarely displays facial expressions and speaks in short, terse sentences despite her high intelligence. She is extremely close to her brother, requiring his constant presence to feel comfortable, and exhibits a brother complex by showing jealousy when Sora pays serious attention to other girls. Additionally, she has a dry and somewhat twisted sense of humor.
