Blue Flames (Ao No Exorcist) (My Ver.)

Hanuel had a mother. Her mother never told where her father went.

Kim Hanuel is a human. Like all the other ones. At least, she thought she was. She had this eye that has been flaming blue. Hanuel kept it safe with an white eye patch from the hospital. Weird things was happening. She was walking home after a long day of school, but suddenly, a black, hideous creature appeared out of nowhere. The creature told that she was in danger and needed to save herself. The 'thing' gave her a sword and told Hanuel to keep it safe, and protect it from any harm. Hanuel didn't know what was going on, but she trusted the demon. What do you think will happen next?
