|大久保瑠美 (Ookubo Rumi)|
A 1st Year student affiliated to the Karate Club.
She wore a skirt usually shorter than most of the students, which in fact she is wear spats (bike shorts). She has a tendency to end her sentences in 「ッス」(ssu) as well as speaking in a semi-honorific manner.
Despite of her tomboyish-like personality, she has a girly-side as seen in some her cards, but not willing to show it except to the player himself.
