The Mafia Princess

After the death of the richest Mafia boss in America, his daughter Alexa goes into hiding until some spies close to her father track her down years later. Alexa has to then learn how to fight, and is trained to be something dangerous that no normal family would ever turn their own daughter into. However, once Alexa's true nature shines, she has to train some new boy that somehow has known her since she was a kid.
