Laeticia

Laeticia is a French girl who is chosen by the Holy Grail as a match for the materialization of Ruler Jeanne d'Arc in the Great Holy Grail War of Fate/Apocrypha. After accepting the role, her personality is temporarily suppressed for most of the war. Laeticia is described as decent and honest, possessing a religious piety that surpasses many others. She accepted Ruler's request without question despite her normal life, being dragged into the Holy Grail War. While Ruler is in control of her body, she is able to witness Ruler's actions and communicate with her. It is much like "watching a movie inside a dream for her", the memories fading fast after Ruler departs from her.
