Izumu:

When she was 3,her parents abused her. She had cuts,bruises,gashes,burns,everything. She ran away. she lived with a women and her daughter. They treated her like a real family. But 2 years later, her parents had finally found her and broke into the house and killed her"family"and took her. Izumu saw what happened and went INSANE! She locked her parents in a tiny cage and only fed them a cracker a day. When they were good, she would give them 5 crackers each. 3 years later, her parents died and izumu hid them in a room and barricaded that door with tape and everything(like yunos back story pretty much XD) and made sure no one even dared to look. If they did, they would have to die. She was walking home one night when it started raining. She was 20 miles away from her home and had no food. She was in the middle of the road when a car was coming and she could barely get away. She fell and the car kept coming until a dragon that was as big as tree that was black and red had grabbed her and flew off. She was scared until the dragon landed and she fell face first. The dragon told her, that her name was murder and she could teach izumu the ways of murder dragon slaying magic(NO STEALING MY MAGIC OR DRAGON OR U DIE! U can only ask me). She jumped up with glee.murder taught her everything.4 years later izumu new everything about her magic but what she didn't know was, murder was gone. Izumu cried and cried. Her exceed knife was beside her crying like izumu was. That's when her day of her life started. She was an assassin like murder wanted her to be. But then she ran into Romeo and he changed her life.(AINT GIVING ANYMORE INFO MUHAHAHA)
