Maria watches soldiers die and decides to stop it herself. That gets her flagged by heaven, cursed with a deadline, and assigned an angel babysitter who actually starts to understand why she won't stop. The show treats her refusal to accept "that's just how war is" as both heroic and genuinely dangerous, never letting you choose between admiring her conviction and fearing what it costs her. Comedy lives in the chaos of her succubus and incubus arguing about seduction strategy while Maria just wants to prevent massacres. By the end you realize the real war isn't between nations, it's between Maria's power and the forces that want her powerless because her existence proves there was always another choice.

Maria wields magic powerful enough to halt armies, and she uses it to break up the fighting of the Hundred Years' War in medieval France. Her interference in battle after battle catches heaven's attention, prompting the Archangel Michael to impose a condition: the moment Maria loses her virginity, her powers vanish. Ezekiel, a beautiful angel, is assigned to watch the witch and keep her from casting spells in front of people. Maria has no intention of obeying. Branded a heretic, she keeps disrupting the war alongside her familiars, the succubus Artemis and the incubus Priapos, while the Church starts plotting to strip her of her power. The result is a fantasy comedy with romance, built on the clash between heavenly authority and one witch's stubborn pursuit of peace.
