In the Middle Ages, a woman named Jeanne D'Arc claimed to hear God's voice. She led a lonely life and was burned at the stake, despite being the voice to lead France to victory in the Hundred Years War. In today's world, she is reincarnated as Maron Kusakabe, a girl whose mission is to prevent demons from stealing people's hearts. To do this, she must steal any artifact that they possess. Her best friend, Miyako, is a detective looking for the thief, without a clue that she's right under her nose. Will Maron be able to save the world from destruction, or will she be caught red-handed by her friend?
