Shirayuki Madoka

She is a sister at the church on campus and a newly transferred teacher this year.

She is a pure Catholic and has a straightforward and gentle personality, which makes her beloved by students, both male and female.

However, because she has always studied and taught at a Catholic girls' school, she is a little naive and easily deceived, and has little tolerance for men.

She got to know Hibiki through tending to the flower beds, and has always been concerned about her.
