Karasuma Miyako

A female teacher who appears intelligent, but is actually mentally fragile.
When an unexpected situation occurs, she can suddenly become hysterical.

Although she does not want to be liked by the students, she makes an effort to get along with them as long as it does not interfere with her work, but because of her calculating personality, there are few students who she is truly close with.

She dislikes life at the training camp, where she comes into contact with students outside of class.

She also has a tendency to be a germaphobe, and finds it painful to be confined to an island with a lot of sports-oriented students.
