One Kind of Demon

In the year 20XX, the world feared the Kitsune that wandered silently in the shadows. Everyone saw them as evil, wicked things that love to play tricks with people, only to kill them afterwards out of sheer enjoyment. However, what the normal citizen doesn't know is that these "evil" Kitsune are actually called the Yako, or Nogitsune, the ones that are actually doing the killing while the "good" Kitsune are called the Zenko. Frightened people cannot tell the difference unless they are to see a murderous act before them. Because of this, there are human hunters--Executioners--that go out and hunt them down, and since people think the Zenko and Yako are all the same, they'll kill any one of them as soon as they are found.
For Kaliko, that is a bit of a problem. All she wanted was to have a normal life with normal people, normal friends, a normal school life, but deep down she carried with her the blood of a Kitsune, and she had the tails to prove it. Eventually she was brought in by a kind and caring woman who had actually taught her how to conceal her Kitsune side, granting her the life she had wanted. Friends were made, relationships blossomed. It was all that she could ever ask for. But the past eventually catches up to her, and she must choose to either give in and have her friends despise her completely, or fight on their side and prove that not all Kitsune are as bad as they would seem. All because of a single promise.
