Lady Devil Manhwa Volume 1 features story by B.Cenci and art by Choco FUKI.

Giovinetta Valdemar, Lady Devil herself, was branded as such after her first husband's heart was ripped out on their wedding night. Years later, she is betrothed once more to a much older nobleman, and in her desperation, makes a wish to the devil of Ducommun for help—a plea that is answered by transforming her twin brother, Johannes, the exalted hero of Valdemar, into a devil himself! Will this creature be her salvation or lead her down an even more treacherous and forbidden path?
