My Fave is Problematic: Phantom Thief Jeanne

As Jeanne, Maron steals paintings possessed by demons trying to steal the beauty of human hearts, weaken God, and strengthen the Demon Lord. By doing so, Maron seals the demons away, restores the affected humans to normal, and leaves a new painting of an angel in its place. This premise intrigued me because the magical girl was a phantom thief, rather than the standard “magical warrior” or “witch.”
