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.

In elementary school, the rich and spoiled Yanagi Naoto was known for excelling in both studies and sports. But then he suffered the first setback of his life when Kujou Mikoto, a girl from a poor family, transferred to his school and performed better than Naoto at every turn. Reeling from this unforgivable blow to his pride, Naoto decided that he had to make Mikoto lose at something…by making her lose her heart to him, which he could then break! Now that they’re both in college, will Naoto finally be able to win Mikoto’s affections–or will he lose this final game with her?
