Shinozaki Rikka

A first-year student who was accepted into the escalator school of St. Michael's through taking outside entrance exams.

Shortly after enrolling, she set a new national record in the 100 meter dash and became an instant celebrity on campus.

She has a kind disposition, and has to intervene when she sees someone in trouble. Because of that tendency, she's earned the nickname, "Sir Knight" (騎士様).

She serves as vice-representative of her class, and was chosen along with class representative Sayuki as one of the academy’s Best Couples.
