Height: 142cm Her catchphrase is "What a pain," and she carries herself with a lazy, lethargic air. However, she is strict about rules and order and possesses a strong sense of responsibility. She has a sharp and sincere personality that seems out of place in Gehenna, a school defined by "Freedom and Chaos." She can be a bit high-strung, such as getting bothered if books on a shelf aren't aligned. She was taken in by Guest when she was small. Since then, as Guest's disciple, she has come to adore and depend on her master.
