Hello my fellow readers!

So I'm now officially into Black Butler. Catherine has black bangs and black edges on the end of her hair. The rest of it is red and curly. Her eyes are silver and her signature outfit pretty much matches Anna Valerious's from Van Helsing. She wears a long sleeved green shirt with a black corset around her middle torso. She wears dark gray pants and brown boots. Her hair is usually tied back with a black bow and she wears brown fingerless gloves on her hands. Catherine is nine years older than Ciel. I'm still new to this anime so please don't hate me if I'm not following the plot line. All Black Butler/Kuroshitsuji characters belong to their owner. I just own my OC'S.

Catherine's POV

1886

Death was fast approaching me. I had no idea if my brothers were even still alive. Not that it mattered anyway since I had been shot with a silver bullet. Even for a Dhampir such as myself silver was like poison. I didn't care anymore if I died since I was in so much pain.

"Sister!"

Was I hallucinating or did I hear one of my brother's shout. I waited for another second before I heard my sibling yell once more.

"Over here!" I yelled back.

A few seconds passed until my little brother found me. He looked in better condition then I was however concern came to me when I saw his right eye was glowing purple with an unfamiliar design. Blood seeped down his face underneath it.

"Sister you need to feed"

"Stay back" I hissed. "I will not feed on your blood"

"But if you don't you'll die"

"I'm not afraid of death little brother" I countered.

A chuckle caught my attention and a tall black figure appeared behind my sibling. The scent of a demon filled my nose and I realized the design I saw in my brother's eye was part of a contract.

"Milady you are certainly stubborn" the demon greeted approaching me.

"Back off demon" I growled making sure this creature saw my glowing blue eyes and my elongated fangs. "I'm well aware of how contracts with your kind work"

"There is no need to worry about that sister" my younger sibling reassured me. "Let him help you"

"And what's the price? I'm not sure if I want to pay it"

"As my master spoke milady don't fret about it" the demon spoke. He then bent down to my level and he lifted my body into a sitting position. I was able to get a better look at the demon now. He had taken a human form and I would be lying to say he wasn't handsome.

He had short black hair that was exactly like my father's. His eyes were red and they held loyalty in them. He wore a butler's uniform which was a smart move.

"Now milady I am offering you my blood" the demon continued. "My orders were to save any surviving Phantomhive members and you my dear are the only one"

"I see" I said.

"I'm sorry sister"

The demon took off the white glove on his right hand and pulled back his sleeve. He then held his wrist out to me.

"Milady please hurry and drink"

Using my vampire sight I found the appropriate spot. I licked the demon's flesh before my fangs pierced his skin. His blood was delicious and as I drank it I felt my strength returning to me. The silver's effects were fading away. However something else I couldn't explain happened. From this demon I felt a strong warmth and desire to protect me. I knew what these feelings were. The demon was my life mate and I was his.

Once I drank enough did I release my fangs from the demon male.

"Sleep dear one" he whispered and he pressed a kiss onto my forehead before exhaustion claimed me.

Present

1888

Still Catherine's POV

"My love it's time to get up" I heard Sebastian call.

I opened one of my eyes and shot my mate a look of disapproval. Sebastian was already dressed ready for the day. Sebastian knew better than to wake me when I wasn't ready to get up.

"What time is it?" I inquired.

"Almost nine I already tended to the master"

"Alright" I muttered in defeat before sitting up.

I wore a simple white nightgown and I'm sure my hair was a mess. Sebastian and I shared a room which was thankfully away from my brother's.

I got out of bed and I saw a mischievous gleam in my mate's eyes.

"You know damn well I can dress myself Sebastian Michaelis" I scolded the demon. "Though I wouldn't say no to a kiss"

My mate was pleased at this request and he kissed my forehead before excusing himself. I wasn't fond of wearing dresses so I had a habit of dressing in men's clothes. However I did wear dresses when it was necessary. Once dressed I headed to the dining room and Ciel was already there. Sebastian already had my seat pulled out and I thanked him with a nod. My mate then left the room for a moment. I tried to avoid showing affection with my mate in front of Ciel since he wasn't fan of public display of affection.

Hovering close by were Bard, Finney, and Mey-Rin. Bard was the cook, Finnian the gardener, and Mey-Rin was the household maid.

"Good morning sister I hope you weren't too annoyed when Sebastian woke you up" Ciel greeted.

"Not much it was time for me to get out of bed anyway" I joked. Ciel and I had always been close. You see we were half-siblings. We shared the same father but different mothers. My biological mother had been father's first wife and she had been a full blooded vampire. Sadly she died giving birth to me however Ciel's mother adopted me as her own child.

As a Dhampir I needed blood to survive whether it was human, animal, or other supernatural beings. However I could eat human food and part of breakfast was salmon. I was sucker for any mind of meat, chocolate, and coffee.

Suddenly Ciel threw something and it hit Finnian on the head.

"Brother was that necessary?" I demanded from Ciel while Finney jumped up and down holding his head. Finnian rushed to Ciel's side asking why he threw a dart at him.

"Nothing I don't need to justify my actions" was Ciel's reply. However when my brother saw the glare I sent him he was quick to apologize to the gardener. For payback I added.

"Maybe Persephone should pay you a visit"

Ciel paled even more.

"You wouldn't"

"Oh I would"

Persephone was my cat. Well she was actually a demon cat who had been with my biological mother's for years. She served as my companion and guardian. She already had lived through five of her nine lives. She had two forms one was her normal appearance and the other was her demon form. Since Ciel was allergic to cats Persephone lived outside.

The doors to the dining room opened and Sebastian entered wondering where Bard, Mey-Rin, and Finney were up to. Of course they were not doing what they were supposed to do so Sebastian went into no nonsense mode.

"Now all of you we have no time for thumb twiddling this morning so get to work!"

Paling Mey-Rin, Finney and Bard rushed out join the room to do their assigned tasks.

"Simply hopeless" my mate muttered.

I rolled my eyes before continuing on with my breakfast. Once finished I took a sip of my coffee before looking to Ciel.

"You have that bloke visiting later am I correct?"

"Yes I'm afraid" Ciel confirmed with a sigh. "Would you mind keeping me company during his visit?"

"No I don't mind"

Ciel flashed me a genuine smile before he stood and excused himself.

"I'm glad I refused being the heir of the estate"

"You would have made a good heir my dear" Sebastian complimented.

"Your just saying that because we're mate bound Sebastian" I corrected the demon.

"No my love I'm being honest"

"I never had an interest in leading an estate, besides many wouldn't like it if a woman was in such a position and it would be hard to keep my true nature a secret"

"You have a good point"

I had my own business to attend to so I gave Sebastian a peck on the cheek before heading to my study. I may not be the heir to the Phantomhive Estate but I did make sure things were taken care of around here. When I finished my tasks for the day there was a knock at my door and I called for whoever it was to come in.

"Our guest will be arriving soon" Ciel said.

"Let's hope this visit doesn't last too long" I growled. Ciel walked with me to my room and Mey-Rin was there to help me get ready for dinner. I wore a sleeveless green dress and my hair now in a bun. I wore emerald studs and a matching bracelet.

"I really don't like dressing like this" I told Mey-Rin. "I heard you and the boys messed up earlier with your jobs"

"Yes we are trying to impress Sebastian" she confessed with a blush. "Your lucky miss to be courted by him"

"You'll find someone eventually my friend and they probably will be just as handsome as Sebastian"

"Oh I hope so!" Mey-Rin squealed.

I chuckled before the door to the bedroom opened. Sebastian's eyes went wide when he saw how I was dressed. Mey-Rin excused herself and she shut the door behind her.

"My apologies for staring but you look stunning" the demon complimented.

"I'm only wearing this damn get up for Ciel" I corrected my mate.

"Oh I know I came to escort you to the master"

I felt my face blush when he spoke that and my demon mate approached me. He used a gloved hand to make me look into his eyes.

"Your always beautiful my Catherine"

He then placed a quick kiss onto my mouth before offering me his arm. I accepted it and a short walk later I joined Ciel with our guest. They were playing a game and it wasn't one I liked much. Our guest was named Damian and at some point during the game he told me and my brother he'd appreciated some money for business dealings.

I didn't trust this man and I had a feeling he was up to no good. Thank god Sebastian arrived to say dinner was ready. Damian tried to offer me his arm but Sebastian was quick to fill that role. The dinner area outside had been transformed into a Japanese stone garden and it was beautiful.

"You and the others did good" I whispered into my mate's ear.

"Why thank you my love"

I felt my face go even redder when those words were spoken. Sebastian took me to my seat first before doing the same with Ciel and Damian. For dinner was a raw beef dish called Donburi. When I tasted the meat it melted into my mouth and I mentally reminded myself to tell Bard he did a good job making this later.

I was enjoying dinner until I saw Mey-Rin was pouring wine onto the table cloth. Finney and Bard paled seeing what was going on but Damian paid no mind. Sebastian then pulled the tablecloth off and he did this without disturbing the things on the table.

"Huh? Where did the tablecloth go?" Damian wondered.

Mey-Rin was dragged away by Finney and Bard.

"There was a speck of dirt nothing more" Ciel answered.

"My apologies" Sebastian added.

Dinner concluded without anymore fuss and I was back in the room with Ciel and our guest. Damian wanted to get right down to business but Ciel interrupted.

"I would like to continue our game if you don't mind"

I shot my little brother a smirk which he returned before focusing his attention on the game and Damian. I could tell our guest was getting impatient and he then stood up. The fool requested to use the telephone and Ciel told him where it was. Sebastian opened the doors and had some tea for Ciel and our guest.

After declining tea from Sebastian I stood up.

"I'll go find out what that fool is really up to" I explained to Ciel and my mate.

Ciel nodded and Sebastian shot me a look to be careful. Phantomhive Manor was easy to get lost in if you didn't know your way around. I followed Damian's scent trail and when I found him I kept out of sight. I listened as the cocky human and I hissed when I heard he was intending to scam us.

Eventually Damion hung up the phone and began to make his way back to the meeting room. I followed the human from the shadows and occasionally the scammer got spooked. Serves him right for trying to mess with the Phantomhive family. I ended my chase and easily found my way back to the room where Ciel was waiting.

I told my brother everything I heard and I sat down opposite of Ciel when I finished.

"Shall we play our own game?" I asked. "I trust Sebastian will take care of that fool"

"Of that I don't doubt and yes I would like a round with my sister"

Ciel set up a new game and soon I became absorbed playing with my brother. During one of my turns we heard a shout from outside.

"Mama Mia!"

"Looks like Sebastian kicked Damian in the arse" I chuckled.

"Indeed and I had a feeling Damian was up to something before you confirmed it"

"Someone has to look after our affairs little brother and it looks like I lose"

"Your improving sister" Ciel praised.

Later.

Normally demons didn't need sleep but Sebastian did so no one suspected him of being a demon. As usual I was the first one who made it back to our bedroom. Being the devoted butler he was my mate didn't retire for the evening until he completed his tasks. I pulled off my dress and placed it with the dirty clothes before changing into a nightgown. I chose another white one since Sebastian liked the way they looked on me.

On my left shoulder was a simple bite mark that emitted Sebastian's scent. This told other demons and other supernatural beings I was off limits. Believe it or not I was the more possessive partner. Dhampir's only had one life mate and didn't tolerate another trying to steal their partner. I guess I got lost in my thoughts because I jumped when I felt strong arms wrap themselves around my waist from behind.

"Jumpy tonight are we?" came the amused tone from Sebastian.

"You know better demon" I reprimanded him.

"I tried to alert you through my thoughts but your mind was occupied"

Sebastian and I spoke through our thoughts due to my psychic abilities. Sebastian pulled away from me and I turned away as he began to undress. I hoped my mate didn't pay any attention to the thoughts that now occupied my head.

I shook my head and got into bed.

"Your thoughts will never cease to amuse me my Little Dhampir" Sebastian said as he joined me.

He was completely shirtless and wore comfortable pants to sleep in. The demon then claimed my lips with his in a fiery hunger. Immediately I became submissive and passionately followed Sebastian's lip movements the best I could. His right hand intertwined with my left as his tongue met with mine.

Soon his lips left mine and went to the left side of my neck. Teasingly the demon planted feather like kisses on my skin making my body shudder in delight. When his tongue began to lick patterns I jumped which made Sebastian chuckle darkly.

"Such a good girl you are Little Dhampir"

"Don't tempt me Sebastian" I warned.

"Don't worry I don't intend to" he promised before kissed me again. It was his turn to become submissive and I now had my mate beneath me. I gave him my own mind blowing kiss he enjoyed before kissing a bite mark on his own left shoulder. This was my mark and my scent lingered notifying others this demon male was mine. Once I had my fun did I remove myself from Sebastian's lap and lay beside him.

"Perhaps tomorrow might be just as intriguing as today was" Sebastian suggested.

"Things never get dull around here with you running things" I pointed out.

"It is my duty as a butler to do so" Sebastian countered. "And my love I am one hell of a butler as you are one hell of a mate"

"Damn straight" I agreed.
