Maria is a powerful young witch living with her two familiars in medieval France during the Hundred Years' War against England. As the war rages on and the innocent get caught in its destruction, Maria becomes fed up with the situation and begins using her magic to try and prevent further conflict in hopes of maintaining peace. However, her constant intervention soon attracts the attention of the heavens, and the archangel Michael is sent to keep her from meddling in human affairs. The divine being confronts Maria, and he forbids her from using her powers, issuing a decree that her magic will be taken if she loses her virginity. Though she is now labeled a heretic, Maria adamantly refuses to heed Michael's warning and continues to disrupt the war between the two nations. But as the Church begins plotting to take away the witch's power and put a stop to Maria's interference once and for all, her peacemaking may soon come to an end. The story follows Maria, the most powerful witch who lives during the Hundred Years' War in France. She despises war, so she obstructs battles with her strong magical powers. Her meddling with her succubus Artemis and incubus Priapos has caught the attention of the heavens, and so the Archangel Michael issues an edict. When Maria loses her virginity, she will also lose her magical powers. A beautiful angel named Ezekiel is supposed to watch Maria and make sure the witch does not use magic in front of people, but Maria continues to use magic anyways.
