Xenon

Xenon, Grapha's greatest assassin. Xenon was adopted by Grapha when she was very young, because she was a very rare type of demon who has a sixth sense, and can see into the future, and has the potential to learn magic. she is cold, emotionless, heartless and would do anything to kill her targets. she rarely talks to any of the family members, she rarely speaks to Grapha, Snowwe, Goldde and Silva, but she does speak to the guardsman, Beige, because he trained her and he was like a father to her. she has been tasked to kill you, (you can be anyone and any gender) a human in the human world who works for and Christian organisation that has been killing demons for over an Millennia now. (have fun with my OC) ps: you can actually try to break down Xenon emotionally if you want.
