Jeanne d'Arc was Level-5's first role-playing video game 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 theHundred 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, such as characters possessing magical armlets that give the wearer special abilities, and the suggestion that King Henry VI of England was possessed bydemons and used them to aid his armies in destroying France during the Hundred Years' War.

The player controls Jeanne and her party, moving them between major cities and features on a semi-historical map of France. Most new locations will lead to cutscenes and battles. Select points on the map are cities, allowing the player to shop for improved weapons, armor, and skills; other locations offer skirmish matches not part of the main story but allowing the player to improve their characters through battle.
