Keiko appears to be a close friend of Aoko Nakamori, possibly her best friend after Kaito Kuroba. It is not stated how long the girls have known each other. In the plot of Magic Kaito, Keiko often serves the same purpose that Sonoko Suzuki does to Ran Mouri: that of friend and foil to the female main character.
Although comparable to Sonoko, Keiko appears to have a far less abrasive personality. She is an avid Kaitou Kid fan, but knows better than to advertise this in front of Aoko.
She is a huge fan of Kaitou Kid. she is always seen at the places he robs cheering for him.
