"Jeanne d'Arc is a tactical role-playing game developed by Level-5 and published by Sony Computer Entertainment for the PlayStation Portable. It is Level-5's first RPG of this kind, as well as the studio's first production for the PSP. The title's narrative makes use of various fantasy elements, and is loosely based on the story of Joan of Arc and her struggles against the English occupation of France during the Hundred Years' War in the early 15th century.
The game has an amount of historical accuracy when it comes to the cast of characters, and contains many who were contemporaries and allies of Joan of Arc. This contrasts starkly with the many fantasy elements of the game. These include Jeanne and other main characters possessing magical armlets that give the wearer special abilities, and the suggestion that King Henry VI of England was possessed by demons and used them to aid his armies in destroying France during the Hundred Years' War."
