Ai is a highly materialistic girl with a prima donna complex, who often talks down to her admirers, and has no qualms with outwardly insulting them, deeming their confessions worthless if their looks aren't up to par with her standards. She is also extremely selfish, but being with Yu reveals her to be a shy person and a sweet, loving soul; she harbors a crush on Kou. She fears rejection and acts dramatically upon receiving it, culminating in an attempt to jump off the school roof. She puts herself through various trials to become more appealing to her choice, and appears so desperate for love that she forces Narukami into briefly dating her. However, due to her lack of actual affection for him, she ends up pushing him around and treating him cruelly. When Ai overhears Kou mentioning he likes Chie. Unable to tolerate Chie, she becomes immensely jealous of her and engages in slapping her. Eventually, she comes to terms with her treatment of others and still pursues Kou, hoping to do better.
