A refined and proper lady, also very calculating, intelligent, manipulative, and sadistic. Always calm and polite to an unsettling degree, she never loses her cool. She's the student council president of Hyakkaou Private Academy, where she is seemingly untouchable. She invented the "House Pet" system, where losers are subjugated by winners in sub-human conditions. Loves to gamble, and believes everyone must play on her terms. Has icy-blue eyes and pale blonde hair. Has no limits nor shame.
