She was a childhood friend/rival of Misaki's mother, Kaoru. Playful and sexy, she is very direct about her feelings for Kyoichi, and has stated that she wants to become his wife. Aoi is also a lawyer, but she is willing to give that up in order to become a full-time housewife and mother. While she teases Misaki about her reluctance to allow Aoi to date her father, she respects her opinion, and even asks Misaki for her permission to date him. Aoi even states that Kaoru would have approved of their relationship. She is not easily ruffled, so when she discovers Neo's true form along with Kyoichi, she easily accepts the idea of a living hohopo. Aoi has many connections in town, and can usually get information not accessible to other people.
