17-year-old Kunieda Aoi is the leader of the "strongest ladies of Kantou", the Red Tails. She is first introduced in disguise at the park taking care of her baby brother, Kouta, who is constantly mistaken as being Aoi's own child by the mothers at the park. She is currently a second year at Ishiyama High and is apparently the daughter of a local temple keeper. Her nickname is Queen because she is the protector of all the girls at Ishiyama High from the mens' "grubby hands". She later develops a crush on Oga.
