You were sitting in a tall tree when a girl around 18 years old came to you. "Can we make a contract?" She asked. "A contract?" I questioned. "Yes, you see, a few weeks ago, a few guys burned down the village I lived in, killing everyone there, except me. I wanted to make a contract that if you help me get revenge on them. Once I get revenge, you can have my soul." She said. "Alright sure. How do you want me to look?" I asked her.
"Could you look around 14 years old, and kinda like me? I want you to pretend your my sister." She told me.
"Alright sure, and where would you like the contract symbol?" I asked her.
She responded "Can I have it on my back? Like near the center?"
"Okay" I said and a contract sign formed on my left hand and her back. I transformed to look like a 14 year old girl, that looks like her. "May I ask, what is your name?" I asked her.
"Oh my name is Cat." She said.
We walked to a hotel, since she told me she was homeless. She didn't have any money, so I had to find a way to get in for free. I bought us a suite for a few months, and I told her to eat some rest, and we will start tomorrow morning. Cat went to bed, and fell asleep almost instantly~Time Skip because nothing went on~
I woke Cat up at 8:30. She woke up and got dressed, and I made her some food. I am a demon, so I don't eat human food, but sometimes I do because why not? While she was eating she had a concerned look on her face. "Your not hungry?" She asked. "Cat, I don't eat human food." I told her. Cat said "Oh okay." And went back to eating.
~Time skip to when she finished eating brought to you by Grell~
"Cat, we should get going?" I asked her. "They only come out at night" she responded. We then agreed just to take a walk down London.
We were walking and talking, not really looking where we were going. I then bumped into someone. I took a step back and looked up the person. I couldn't recognize them, but I knew they were a demon. He looked down at me and said "Hello [Y/N]" "S-Sebastian??" I said, surprised, confused and excited.
Sorry for short chapter, I promise the next one will be longer!
