Maggie Mui (マギー・ムイ Magī Mui, a.k.a. Ma-nee) is the tall, boyish, quiet middle sister of the Paper Sisters Detective Company. Her surname (which can also be spelt as Mei or Moy, depending on the system used) means "plum" or "prune" and is a common one in Hong Kong and the neighboring Chinese province of Kwangtung. (Until her recent death, Anita Mui was a leading Hong Kong actress and recording star.) A Bibliophile, she faints in Jinbocho due to the sheer amount of books present.
