Five years old and like that. She'll be either a millionaire or a corpse by the time she hits 15. It's because she will try to blackmail a fortune out of a rich person. However, I'm not entirely sure she will be able to choose the target wisely enough. In the first place she can't even target a respectable person because then she would have no grounds for blackmailing. It will need to be someone who lusts after a young girl, but will then meekly pay when threatened with consequences. It can't be someone who takes her but then will get wrathful when blackmailed. However, seeing how she's trying to make an enemy out of her own big brother, it's possible she will choose very poorly.
