Manga Like Frau Faust

More than a century after an eccentric scholar made an infamous deal with a devil, the story of Faust has passed into legend. However, the true Faust is not the stuffy, professorial man known in fairy tales, but a charismatic, bespectacled woman named Johanna Faust, who happens to still be alive. Searching for pieces of her long-lost demon, Johanna passes through a provincial town, where she saves a young boy named Marion from a criminal's fate. In exchange, she asks a simple favor of Marion, but Marion soon finds himself intrigued by the peculiar Doctor Faust and joins her on her journey.
