A mathematics teacher at the school. She is beautiful, but her sharp eyes and rarely expressive face give a cold impression. However, she is not condescending to her students, just serious. She is passionate about education, and answers questions in a polite manner. She has a strong sense of self-discipline, but when confronted with her favorite cat, she tends to relax. Outside of work, she is naïve, weak to push, and defenseless. [From official site]
