Nana-shimura Stories

What if All-Might had a twin sister? What if she was also quirkless? Minato Yagi had always been there for her brother, her big hearted, courageous, Idiotically reckless brother. However one day, after meeting a stranger who saw potential in her quirkless brother she managed to become the all time champion of stressing about her brother. What happens now, years later, she had lost all connections with him and darker forces turn their attention to her. Will villains find her and use her for leverage? Sooooooo. I decided to do something with my life and try out writing a story... first story (yay) None of the art is mine and all the original characters and some of the plot belongs to Kohei Horikoshi. Because Time frame is all back I'll try to fill in as many plot holes as possible.... So yee (English is my first language, If there's spelling errors its just cause I'm an idiot lol)
