Maiko is a member of the Ghoul Restaurant, where she goes by the alias Madam A. She is also shown to have an intuition which hasn't failed twice, narrowly escaping when Kaneki attacked the Ghoul Restaurant with Tsukiyama's assistance, and during the auction, where she left moments before the CCG streamed in.
