Assassin-class Servant introduced in Fate/Grand Order's Fuun Karakuri Illya-jou event. She is based on the folklore Japanese figure who supposedly performed magical arts to various historical figures in the Muromachi period. In Fate she appears as an android who has fully replaced all parts of their physical body and no longer remembers what gender her original body was. When she constructed Katou Danzou, she had a male body.
