U.A's Ghost

Blair had a hard life. Abusive father, brothers, and major bullies/ex friends. She got third in the entrance exam and made it into U.A, class 1-A. Halfway through the year after she graduated and became Winter, she was drowned in the U.A pond. The drowning was stated as murder because there were signs of struggle and a mask soaked in chloroform on the ground near the pond. After the incident the pond was closed and soon after Pro hero's and bullies of Blair were found dead in an alleyway near the school. From then on strange murders happened to some students in the ally. Some were stabbed, shot, and/or beat to death, some were even had there organs pulled out. One thing that never changed was that there was two syringes, one in the forehead and the other in the heart, and a nurses hat on the ground next to the unlucky victims. There was also a message on the wall, 'They had no heart and let their mind take charge. So I gifted them a remedy, F O R F R E E !' written in blood. Witnesses ,very few, claimed that they heard a song while the victims ran.
