Mitsuri

Personality: Polite and treats everyone equally. Possesses a strong naturalness that allows her to smile and overlook the boys' dirty jokes and rough behavior, saying, "It's good that they have so much energy."
Role: Becomes the object of protection that the boys unite to defend, thinking, "We mustn't defile her." On the other hand, she herself seems to find the unique "foolish energy" of a boys' school amusing.
