Ai is a tough girl with a typical bosozoku personality. She is violent, intimidating, and strong-willed.

Despite her rough exterior, she values her femininity and is a romantic. She is swayed easily by appeals to her romantic side, is somewhat tsundere, and likes cute things such as stuffed animals. She has strong feelings for Shousuke, who she believes to be a hardliner like her. She also seems to be somewhat sheltered; she believes arcades are "immoral" and calls Hitomi's complex coffee order "a chant." She is also shown to be shy as she won't drag Shousuke to places herself, and she cannot give him her Valentine's chocolate.
