Authors Note

Y/N is part of the Shie Hassaikai. She was raised to be an assassin, a warrior, a criminal. But one day that all changes when she gets the opportunity of a lifetime. She gets to be an actual teenager and go to UA High School. What happens to this Yakusa Assassin when she meets a certain hot head? Read "Angel or Demon" to find out.

I do not own any of these characters besides the story of Y/N (She is based on my own personal OC) and a few side characters I created.
