Jeanne d'Arc

Jeanne d'Arc is the spirit of the historical figure Jeanne d'Arc, who occupies the body of ordinary French high school student Laeticia, whose appearance is very similar to Jeanne, though classifying her as a Pseudo-Servant. Laeticia mostly remains within Jeanne's subconscious, but occasionally interacts with other characters. At first, Jeanne is unaware why she was summoned as Ruler beyond ensuring the Greater Grail War occurs fairly. However, over time she learns her true purpose is to stop Amakusa from hijacking the war to fulfil his own wish.

Jeanne aids Sieg in starting a new life, but has visions that he will join the war despite her attempts to prevent it. She falls in love with Sieg, but at first assumes these feelings belong to Laeticia. Jeanne is courageous, compassionate, humble, and honest, disbelieving that she is a holy maiden as she was canonized as. As Ruler-class, Jeanne can command other Servants using Command Spells.

Jeanne has two Noble Phantasms, "Luminosité Eternelle", her military flag, which can repel enemy attacks; and "La Pucelle", which manifests the flames that killed her. Jeanne is defeated in the final chapters of Fate/Apocrypha, whilst Laeticia is spared. Her spirit later reunites with Sieg in the reverse side of the world. In Fate/Grand Order, Jeanne appears in Orleans as both an ally and antagonist, as the real Jeanne goes into conflict with her Avenger-Class Alter self, who became Orleans' demonic ruler. Alter-Jeanne also appears in other Singularities and Lostbelts as a recurring ally.
