Francine (フランシーヌ Furanshin) is a type of advanced artificial body used by Shiori Momono. It substitutes for her disabled original body, allowing her to accomplish missions given by Index. Materials that were used to make the body was most likely magical, since the skin is just as soft as a real human skin, although there is a fault that should Shiori wear anything other than silk, her skin will become sore. While the outside was almost identical to real human skin, inside it was augmented with steel frames as the body's skeleton.
In the anime, the name Francine was never mentioned, but Shiori still has an artificial body, albeit a doll-like one.
