Aoi is a second-year student and the third 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 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 men's "grubby hands". Because of Oga's dense personality, he has yet to realize that the girl he befriended at the park and Kunieda are one and the same. Despite her tough personality, she has a rather girlish crush on Oga but refuses to admit this fact to others. She can feel Saotome using his demon power, which shows she has notable strength for a human.

Kunieda differs from the other thugs at Ishiyama in that she has formal martial arts training from her grandfather, the master of the shingetsu style. She is also not a bully, and steers the leadership of the Red Tails towards preventing unnecessary fights in the school.
