In playground, the other kids bullied her, called her mother a witch and her father was a devil. She cried so many times over the mean comments. Her mother wasn't a witch, her father was not a devil. They were just two different types. So when she was born, she had horns like her father but her mothers foxy body. As time passed on and she kept hearing over and over: Your mom is a witch and your father is a devil, somewhere deep in her mind, she started to believe it. Perhaps she also was a witch but also a devil? Two in one with powers?
As she had found an unusal staff during an investigation on a digsite, it unlocked what it saw in her mind. Power, power beyond imagination.
Now she was what the bullies had called her. A demon witch.
