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 and condescending towards others, taking people and regulations for granted, especially the protagonist.

But being with the protagonist reveals her to be a shy person and a sweet, loving soul.
