What if Gohan had a twin sister with the soul and memories of someone who had watched the Dragon Ball Z TV show? That's Hanna, and her goal is to protect Earth. MC is going to attempt to manipulate the canon. This means that even after she gets powerful, she'll be hiding her powers. (This is just a pet project of mine. Don't expect updates to be too regular, and while I have a general idea of where I want the plot to go, I haven't set a plan in stone for it. While the plot will follow the same arcs as the TV show, not all of the movies will be incorporated. By the way, this is MY INTERPRETATION of the canon, so not all information in the story will be completely correct when compared to the official canon.)
