The Jeanne d'Arc story begins far in the past, when a great war was waged by mankind against demonic armies attempting to invade the human world. During that time, five brave heroes created armlets to restrain the demon gods. In a quest to turn back the rueful army, a young crusader named Jeanne is commanded by mysterious voices to use the power of the magical armlet to seal away the demon king and recover her homeland once and for all.
