Maria the Virgin Witch

Fuente: AniList

During the Hundred Year's War between England and France in the Middle Ages, a powerful witch named Maria lives in a secret forest with her familiars. She hates the war around her, and will sometimes stir up trouble against the church that does nothing to stop it. Her interventions into the world, however, run against the plans of heaven, earning her the attention of the Archangel Michael.
