"In the otome game's villain route (omitted)... the heroine turned out to be a brutish cross-dressing guy, so please help me."

Official Title: "I Was Reborn as the Villainess (Sacrificial Lamb Type) in an Otome Game, and Was Enjoying Satisfying My Sadistic Desires, but the Game's Heroine Turned Out to Be a Brutal Cross-Dressing Bastard, So Please Help Me" I was reborn into the world of an otome game as a sacrificial lamb-type villainess whose bullying of the heroine directly becomes conquest character event flags. In order to let the heroine enjoy her otome game life (official reason), and to satisfy my own sadistic desires (true feelings), I was fulfilling the role of the villainess when it was revealed that the heroine who came as a substitute was actually the true heroine's twin brother in disguise. I sincerely apologize, could you cooperate in breaking the flags...? Wait, you want me to set flags and establish a reverse harem ending? Disguise myself as a woman, deceive the conquest characters, and ultimately use contract magic to enslave them and take over the country? ...I deeply regret getting carried away with wanting to become a sadist, so someone please liberate me from this demon.
