A 19 year old girl who meets aliens (Nekketsu Uchuujin) and giant talking chickens (Kobe to Watashi). She seems pretty fine with it. In Nekketsu Uchuujin, she is heartbroken over her cheating boyfriend but is quickly cheered up by a hot-blooded alien who shows her his time machine. In Kobe to Watashi, Ai explores the beautiful city with a singing chicken-man. It is unclear as to when Ai visits Kobe, but it is presumed during a time after she met the hot-blooded alien. (The TV screens in the Kobe train stations display images of her adventures with the alien.) How Ai returns from the future is unclear. This does not get in the way of enjoying her Kobe vacation.
