Her life was about to take a turn for the worst, but with Nadia behind the wheel, she seized Fate by the hairs of its head and yanked it into a sharp U-turn.No more weakness was allowed! If something wanted to get rid of her, she would stab it to death. If someone wanted to trample over her, she would shoot them into a beehive. And there was no stopping her because she had the strongest weapon a main character can have: the System!
