"I'm going to chop off your leg!" "Ugh!" I woke up from a nightmare to find myself as a beautiful girl in a strange mansion! I thought my reincarnation gacha was a huge success☆, but it turns out that my true identity is the spiteful stepsister from the fairy tale "Cinderella." In the story, there is a tragic route in which my stepsister gets her leg chopped off. And Cinderella, who is supposed to be kind-hearted, is screaming that she wants revenge on me. If this continues, will I really get my leg chopped off?! The key to avoiding the tragic route is the existence of a wizard and for me to become the "villainous daughter"?! A leg-or-die fantasy story!
