Mikoto Kujou

She is a poor, low-class girl but she is smarter and stronger than both boys and girls. Yanagi refers to her as a rival cause he always is second in anything while Kujou is first. She is quite dense in several things like the fact that she does not know Yanagi's feelings for her even though he followed her from primary school to university and even joined the astronomy club to make sure no guys approach her.
