Yukimura Satsuki♀

She is the head of the “ Blue Lily Dormitory,” which places a strong emphasis on academics and academic performance. Since entering the dormitory, she has been ranked first in her class in both academic subjects and overall performance. She does not overlook even the slightest mistakes of her teachers, and often sharply points them out.

She has no interest in anything other than her studies, and is not afraid to declare that love and sexual activity are unnecessary. She is ridiculed as an “ice-lady” because she enforces these values on her students and forbids all entertainment in the Blue Lily dormitory, but she is also a kind older sister who aspires to become a doctor for her sick brother.
