Ai is generally an introverted girl who sticks to being alone most of the time. She dislikes being around people who have hurt her friends and is known for being brave and protective of people she cares about. At first, she was not considered important, and did not take into account special requests to get them. However, she eventually befriended a new girl named Koito Nagase, who was also introduced to the ostracism of her peers. As a victim of bullying, Ai is extremely self-deprecating.
