Feature
Ai was named after "Ai Saotome" from the comic "Ai-to-makoto". She has a habit of resting her cheek on her left hand. She is broad-shouldered and heavy-set. People say that the characteristics of her face are hard to define.
Character
Ai is patient and faces everything steadily. She is very earnest and a genius in effort. She is on bad terms with Pan. So she stays away from Pan as much as possible. But with Pan's daughter, Pal, Ai fights every day while maintaining a good relationship. (Ai looks like Tom in "Tom and Jerry".)
