Sailor Ray and the Darkest Night

I suppose I choose this life, but often times I wonder if the choice was really my own. My name is Sailor Ray, and I'm a hunter of all things supernatural. There are others like me, but we all do what we do for our own reasons. Some want to make the world a better place, while others want balance. I want revenge. On the day my father died, I made a pact with a demon. In exchange for saving me from the same fate as my father, I promised him my body as a vessel, and once my revenge is obtained, my soul is to be claimed by him. I was only using him, just like he was using me. Neither of us plans to keep our end of the deal. When our pact was first made, he was weak, a dying spirit. Now, as he heals within me, I can feel his presence growing stronger with every passing day. I'm not stupid. He plans to take over, and I plan to kick him out.
