In the past, there was a great war between humans and demons. Five heroes created five magical armlets and used their combined power to seal the demons away. Much time has passed, and now France and England are in the midst of the Hundred Years' War. Domrémy, a small village in the Lorraine region of France, was celebrating a festival when suddenly English soldiers attacked. A village girl, Jeanne, was led by a voice from the heavens to save France. Thus begins the journey of Jeanne, and her friends Roger and Liane, in the war to free their country from the tyranny of the demon-controlled English army.
