Chapter 1: The infamous Killer's Daughter

Hey, This is it! I'm not sure about the title yet but this is A Cat for a Demon.

I came up with this first chapter while listening to Dance With the Devil by Breaking Benjamin, so It may have something to do with the song. By the way, its a great song, you should listen to it!

I hope you enjoy this first chapter!

I don't own Black Butler, enjoy!

Ciel Phantomhive drank from his tea and he read the letter.

"So, a new mysterious resident have moved in not too far from here?" Ciel asked looking up from the letter.

"The queen request we greet then and find out why they are here. We must also report to her with that information along with who they are, my Lord." His butler Sebastian said as he set down a plate with strawberry shortcake on the desk.

"Why must the queen insist on making such useless demands?"

"My Lord, perhaps we should follow through with this task without complaints."

"Why is that?"

"May I ask, have you seen who it is that is occupying that mansion?"

"No,"

"It is Yuri Catherine Demetrio. She is the daughter of the infamous murderer in London, Jason Demetrio, My lord."

"A girl? But I could have sworn..."

"Yes, my lord, she is forced to hide her identity so she can be the head of her family. She goes by the name Casper Demetrio."

"I see, but what about her father being a murderer? Doesn't that ruin her heritage?"

"Yes, but the queen knows of who she is, and that she does not follow in her father's path, yet the queen is still wary of her. That is why she asked us to see why Miss Demetrio has come here."

"Very well, then, we will go see her later today."

"Very good, My Lord."

Catherine's POV

I stood in the main hall. It was much bigger than my old home. I turned to Edward and smiled.

"Will this do, young mistress?" He asked.

"Yes, actually, it may even be too big." I smiled bigger and walked further. "I am going to change now that I am out of the town."

"Very good, My mistress."

I walked up to my chambers and sat on the bed. I undid the white button up after taking off my red coat. I slid on a sleek long sleeve teal blue dress that went to my ankles. I let my hair down that hung to my shoulders. I laid the hair pins on my desk and sighed. I was glad to able to be in my own home as a female.

I moved my hair away from my neck. On the back-side was a black-purple coloured satanic symbol. This was what kept me bound to Edward.

I walked down the steps and into the kitchen.

"What are you making, Edward?" I said leaning on one of the counters.

"It is a secret, my mistress." He smiled.

"No fair I-" I was cut off by a knock at the door. I sighed and looked to him.

"I will get it, Miss Cat." He walked out and I raced upstairs quickly putting my act back on. I buttoned up the white shirt, slid on some black slacks, and put on my marroon jacket. I put on my black shoes as well. Before leaving to go downstairs, I pinned up my hair in the back and checked for loose strands in the mirror.

I slowly made my way down the steps. I smiled at Edward and our guests.

"I apologize for my tardyness to greet you, I was taking care of some quick buisness. My name is Casper Demetrio; this is my butler Edward Claven." I smiled and bowed to them.

"It is nice to meet you. I am Ciel Phantomhive and my butler Sebastian Michaelis." The shorter boy stuck his hand out. I slowly reached to his hand and shook it. I smiled to Sebastian who seemed to be having a glaring contest with Edward.

"Edward, Why don't you continue with dinner, I will take our guests to the living quarters."

"Yes, My m-lord." He bowed and walked to the kitchen.

"Please, follow me. What brings you to our residence, if I may ask?"

"We heard that you were new to the town and decided to greet you." Ciel said.

"Really?" I balled my fists. I knew Sebastian was more than he showed.

Ciel's POV

We followed close behind him. My fingers twitched. I saw it.

On his, er, her neck was the same symbol on Sebastian's hand, and on my eye. I turned to Sebastian; he must have seen it. I could tell he was being catious; he was keeping close to me.

"The queen sent us here to meet you. We aren't her to socialize." I spoke up.

"I figured as much. Who'd want to meet the murderer's daughter?" She turned to us. "I'm 'London's Demon'! No wonder she sent you to kill me. Edward!"

Sebastian held me against his chest to protect me. Edward jumped over us and protected her as well.

"Why have you really come here?" She asked as she finally let her shoulder length hair down.

"The queen sent us to find out why you were really here." I said pulling away from Sebastian.

"To get away from my father! He tried to kill me! I have plans to live until my contract is completed. I know Sebastian is a demon. He is one of three in this very room!"

"Why did the call you a demon in London?"

"I'm surprised you don't know,Ciel. Have your demon tell you. I'm done talking. Show yourself out when you're ready. I have nothing tto hide here, so feel freel to snoop." She said walking away and chuckling softly.

xXx

I was sitting at my desk two days later. I still couldn't get over what she had said.

'have your demon tell you.' He still hasn't told me even though I've asked plenty of times.

"Sebastian, tell me what she meant!" I demanded as he poured the tea.

"You received a letter to go to a ball tonight at her residence. Perhaps you can ask her then." He replied and handed me the letter and my tea.

It was later that night and I was ready to go. I got in the carriage and rode to the Demetrio Estate.

Catherine's POV

I was dressed in my usual suit. After my first announcement, I would change into a dress so I could actually dance how I pleased. I, Casper, would be busy with a few things in my office, so my 'sister' would take my place there.

I walked out to the main hall and stood on the balcony.

"Thank you all for coming today! I am very glad to see you all have arrived safely. I unfortunately have a few matters to tend to in my office, so my sister will be taking my place while I am busy, but there will be time for me to greet you all in about an hour. Thank you." I said and turned to go to my chambers.

I quickly changed and snuck out. I dashed out to the main balcony outside. I looked up to the stars. I usually did this at times like this. I heard a knock at the door and turned.

Sebastian Michaelis.

"I don't mean to intrude on you, but I would love to share a dance with you." He said and put his hand out.

"With me?" I asked.

"of course, who else?" I nodded and took his hand. "You are much more beautiful today then when you were angry at us before."

I smiled at him and looked at his eyes. He must not remember who I am. "You don't remember me do you?"

"Yes, I do. You were once a former master of mine. Don't let how long I have been away from you fool you. I would never forget an important face."

"I see..." I met with his eyes, which was a big mistake. Those perfect eyes searched me. They took me in and captured me in a swift movement. He had spun me around and locked me in his arms.

In a split second I was being carried away. "I apologize, miss Catherine, but you must get ready for the ladies to dance with you." Edward said as he dragged me away.

Well, that's it for now! I hope you guys like it. There will definitely be a few cool twists to this soon.

Anyways, Please R&R and Fav&follow! Thank you and Good night/day!
