Maria the Virgin Witch
純潔のマリア (original)
Takes place during the Hundred Years War in France. Maria, a powerful young witch who cannot tolerate war, uses her powers to intervene and keep the factions at bay. Assisted by her succubus and incubus familiars, they are mostly successful until the Archangel Michael takes notice and decides to put a stop to her interference. He tells Maria that her powers will be stripped away if she loses her virginity, and also forbids her from using magic publicly. To ensure this, he posts the angel Ezekiel to watch over her.
