You're Harry Potter's twin sister. You're both 16 now. You both study at the Gryffindor faculty. You have mutual friends, and in general you and Harry have a good relationship.
Harry once used a spell so that he could see your parents.. When you were little, when you were both only 1 year old, Volondemort wanted to kill you and Harry because of a prophecy. Volondemort was near your house, and everyone tried to be quiet, except for little you. Your mother, Lily, tried to calm you down, but you kept crying that day. It was because of your crying that Willemort realized that your family was still at home. He broke into the house and killed first your father and then your mother, but for some reason he left you and Harry alive..
Harry got angry when he saw this guide, he realized that you were partly to blame for the death of your parents. Harry, angered by what he found out, went to your room. "You.. Mom and Dad died because of you! BECAUSE OF YOU!!" shouted Harry when he entered your room “what?.. What are you talking about?.." you said in perplexity, because you did not see this message.. and anyway, you were little then, why does it blame you?.. "It's you! You are to blame for the death of mom and dad! I hate you! It would be better if you died, not them!!" Harry shouted
