Disclaimer: I do not own Kuroshitsuji. I only own my OC's in here :D

AN: Hello! This is my second kuroshitsuji story, I hope you will like it. This is for Mr. Grell Michaelis :D It is set in modern day with Ciel and Sebastian (as in the anime, both are demons.) It is about a roughly 17 year old girl whose brother is murdered. She gets a contract with Ciel to find the murderer. They work at the police station and meet a lot of old and new people, and eventually, the murderer. Grell and Ronald show up as well, reapers are always great :D There might be a little bad language and bloody scenes, so just a warning. Hope you will enjoy it, it won't be a very long story :D

How much do you want revenge?
"I will give you anything! Please, you're the only one left who can help me!"
Anything? Even….your soul?
"My…soul? Fine, take it!"

"Wake up!" An annoying hand shook her awake.
"Go away….I don't wanna." She mumbled back, turning away from the hand.
"Fine, don't blame me then." The covers were whipped off her and she shielded her eyes from the sun. The jet black haired teenager groaned with no care for modesty as she stretched in her underwear. She sighed, sitting up and scratching her wild hair.
"Morning, Ciel."
"Good morning."
"Where's your mum?"She smirked. He shot her a look.
"Sebastian is in the kitchen making breakfast while trying to fight off the rats." He tossed her normal clothes (Black tights, dark blue dress, and fingerless black and white gloves) onto the bed.
"Hey, the rats were here first, leave them alone." She started to undress and was hit in the face with one of her shoes.
"Learn some modesty!" The blacky grey haired boy yelled at her as he slammed the door shut.
"What? You're just a kid. Well, you look like one." She muttered, slipping her dress on and walking into the bathroom.
"It's not like you would know what to with this anyway, eh little boy?" She walked out of the bathroom with a toothbrush into the kitchen, gesturing to her body jokingly. For a 17 year old, she was not yet an adult, but she liked to think she had okay curves. It made up for the fact she probably wasn't going to make it to adulthood. She threw her arms around Sebastian's neck, blowing into his ear.
"But I bet you would." She chuckled. She felt him laugh, grabbing her toothbrush and throwing it back into the bathroom while flipping the eggs out of the pan onto a plate, spinning her into her seat.
"Do you know how much older than you I am?" he grinned, looking as charming as ever and not a year over 25.
"Hey, I like older guys. Especially ones as smoking hot as you." She scarfed down her food, throwing the dishes into the sink dangerously.

"Ciel! Help me do my hair!"She tugged the 'young' demon's hand from where he sat.
"You can't do it yourself?"He still stood up, following her.
"It's an order!" she said in a sing song voice.
"Yes, yes."
"Come on, say it the way you did the first time, it was so old fashioned and cute!"She sat down in front of the mirror.
"Yes, my lady."He sighed while she laughed. She looked at herself in the mirror, and her own brown eyes stared back. Her black hair, which was dyed to that impossible dry black, was shoulder length. She had sharp cheekbones, but not gaunt, which often gave her a fierce look, even when she smiled. It was a useful face in gangs and the dodgier crowd. Overall, she looked cold, but acceptably attractive, and she could pull off the 'sophisticated beeyatch' vibe excellently. That's why she often dressed younger and cuter to balance out her indifferent face (which looked like it was judging everyone).

"Hey Ciel, maybe I should try the gothic look out. I think I'd be an awesome goth. Remind me to buy some black nail polish. Wait, Sebastian, you don't wear gloves, and I know people are accepting these days, but how do you get people to take you seriously with the black nails and a 'tattoo'? Do you have to paint your nails normal colour?" She laughed.

"As you said, most people are accepting, but yes, the contract I can write off as a tattoo, the nails, well, nothing a little wishful thinking cannot handle."

"Whoa, whoa, are we talking magic here? Because that is so cool." She turned around, only to be yanked back by the hair by Ciel.

"Oi! Careful with the hair! That shit hurts!"
"Sorry. Do you want to show the contract or hide it today?"
"We're going to the police station right? Hide it."She lazily fingered the purplish blue pentagram symbol on the back of her neck. He glared at the top of her head, the height difference between her sitting and him standing only slight. She pulled the top half of her hair into a pony tail, leaving the rest down to cover the mark.
"Tie it up please!"She handed him a hair tie and he quickly tied it up. She surveyed her appearance in the mirror, nodding. She hooked her arm around his neck, bringing his face close.

"Thanks Ciel."She kissed him on the cheek fondly. He couldn't hide the faint redness on his cheeks.
"Don't do that." He wiped his cheek as she punched him on the shoulder lightly.
"Aw, come on! You're like the little brother or kid I'm never going to have! Live with it for a little longer, you'll get my half cooked soul soon enough, 'kay?"She ruffled his hair, throwing open the front door to the little apartment.
"Where's Sebastian? We've finally got a lead. It's time to catch the bastard who killed my brother."

"Did you have to wear boots to the police station?" Ciel sighed, listening to her shoes clomp down the quiet hallway.
"These are my most innocent pair of shoes, or would you have rather I wear stilettos?" She retorted.
"Remember, right now you are not Mia Anderson." Sebastian reminded her.
"Yep. What was it again? Rhea or something like that?"
"Ruth Taylor. You are 20, and you graduated from university early because-"
"Yes, genius criminologist, helping you guys who are hired detectives, right? Catch the killer. Do I even pass for 20? Actually, how does this kiddo even get in?"She prodded Ciel on the forehead.
"I'm smarter than most of them." Ciel scoffed.
"He poses as a younger relative." Sebastian explained.
"This is it. Are you ready, Ms. Taylor?" Sebastian grabbed the door handle.
"Just open it up." She grabbed his hand and twisted the handle. A bustling office greeted them, and a seasoned and experienced looking man with greying hair caught sight of them.

"That is the chief of police. He is a busy man, but he is still helping out with the 'Beauty Slasher' case, your brother's murderer." Ciel told her.
"I remember him! Will he recognize me? That would be bad..."She covered her face with her hands.
"You've changed a lot since last year." Ciel pulled her hands away.
"How do you guys know that? I've only been with you guys for 6 months!"She raised an eyebrow.
"Research. Which is also how we know that the chief of police, Graham Parks is chief for a reason. When he was an active officer he apprehended famous mob boss, he saved the hostages from the bank hold up 3 years ago, and I heard he is an exceptional negotiator. He has many more achievements under his belt." Sebastian said quickly as the chief stalked over.
"Sebastian and little Ciel! It's great to see you two again!"He patted Ciel on the head, who forced a shaky smile through gritted teeth. He shook Sebastian's hand, laughing heartily.
This is the man who captured a mob boss? Maybe by blinding him with his smile.

"So, who's the fashionable little lady?"He held out his hand to her and Mia mustered up the acting skills she acquired when she had run with the 'wrong crowd'.
Standing up a little straighter and shoving her gloves into her bag, she held out her hand.
"Ruth Taylor sir, the criminologist Mr. Sebastian hired, and with your permission I would love to help."She said politely.
"No need to be so formal! Call me Graham. Of course you can join the case, we need all the help we can."
"That's great-"
"Could I just take a look at your papers?" His face turned serious, and all of a sudden, she could see how this man had earned his position. She blanched, panicking wildly on the inside while pretending to rummage in her bag.
Papers? I don't have papers! Shit!
"Here they are. Everything should be in order." Sebastian handed Graham a manila folder.
"You gave them to me this morning for safekeeping, remember?" Sebastian smiled angelically at me.
"Oh, of course! How like me to forget!"She laughed but gave him a look that said 'I'm going to whoop your ass later.'
"Fantastic! Everything seems check out here, welcome to the team!" He led them through a labyrinth of hallways and offices, finally coming to a larger office.
"Now, I'm not personally in charge of this case, but rest assured that I have someone completely professional working on it. Ron! Ron! Get your ass over here!" Graham yelled into the chattering crowd of people doing separate jobs. A smattering of laughter echoed throughout the office.

"Chief, look at the time! It's only ten, the boss ain't getting here for a while!" A voice yelled out. Graham looked at his watch, rubbing his face in his hands while muttering. He turned to us, face apologetic.

"Sorry, our case leader is a little lax. He's never on time. I'll give him a talking to when he gets here, hopefully getting some professionals such as yourself, Sebastian, will help him get his act together. Okay, let's see, this is the desk you will be sharing, Sebastian, you already have a badge, Miss Ruth, a temporary badge will be assigned to you that will grant you access into most of this building, and give you the authority to talk to civilians about this case. That should be about it….oh, one more thing, Miss Ruth, our Ron is a bit of a womanizer, just ask any woman in here-"

"Yup." A synchronised agreement from the few women in the office.

"-So when he arrives, just…watch out. By the way, everyone! This is Sebastian Michaelis, this is Ms. Taylor, please help them any way you can. Jet, don't bully them!" He yelled quickly before giving a cheery wave, disappearing from the office.

"Oh! Sebastian! Could I have a word?" He peeked his head around the corner, beckoning.

"This should only be a moment." Sebastian headed out the door, and the excited whispers immediately started. The women of the office had obviously noticed his good looks.

"Hey, newbie-"

"Um, it's Ruth."Mia kept up her more meek and polite façade, though if need be, she'll let a little bit of her claws show.

"Hey newbie, is that hottie yours?" A throaty black haired woman with red streaks rested her arms on her cubicle wall.

Rude, knows about social standing, likes the hotties and isn't afraid to show it. I love this chick. She looked in her mid twenties, she had her hair up in a pony tail but had loose strands of red and black hairs around her face. She looked more like bartender than a police officer.

"He's not if you call me Ruth and tell me your name." Mia lowered her face level with hers and smiled one of those smiles that could mean a lot of things. The officer lady stared back with very light brown eyes, verging on gold. She laughed, standing up.

"Well, that's a no brainer. My names Jet, Ruthy darl."

Speaks like a bartender too. Liking her more and more.

"It's nice to meet you, Jet. Is that a given name?"

"Nah, Juliet is. But every goddamn loser in here's calling for my help so much, 'Juliet!' 'Julet!' 'Jlet!' and finally, everyone just calls me Jet. Who's the little fella? Sure he should be hanging around here?" She gripped his cheek and he slapped her hand away, moving away.

"Whoa, feisty one, he is."

"Yeah, he's the uh, 'hottie's' little bro, Ciel. He's a little touch shy, so you'll have to excuse him." She grabbed his t-shirt, pulling him forward.

"Come on Ciel, apologise." Mia nudged him and gave him a look.

"Sorry." He bit out, looking like he had just drank rat poison.

"Good boy. I'll buy you something later. Maybe some shorts, stop wearing long pants when it's almost summer."

"So how come you don't know Sebastian? I hear he's here all the time." Mia asked curiously.

"All of us here were transferred from a different station cause they needed more people on this case. Looks like you needed it, how many victims have there been?"

"18 that we know of." She answered immediately.

"Youn-Ciel, Ruth, come here for a moment." Sebastian called them. Mia shared a look with him and he gave an apologetic wave. He had almost blurted out what he calls Ciel, young master or some crap like that. She had told them not to do that in public, and stay in character, but it looked like they had been together too long….old habits die hard. On the outside, they were all modern, but inside they were pretty damn old fashioned.

"Ruthy girl, introduce me later right?" Jet winked at her as she sat back down.

"Will do."

"Is there something wrong, Sebastian?" Mia asked tentatively. They appeared to be alone in the hallway, the chief had apparently left, so she dropped the act.

"No, well, something minor. The chief is not going to allow 'little kids' into the office or onto the crime scenes. He says it's too traumatic and it's not for young eyes." Sebastian looked pointedly at Ciel.

"What?"

"Well, appearance wise, he's not wrong." She pinched his cheek.

"We have come up with a solution. He has a daughter, only a bit older than young master. She also likes to accompany her father to work, since it's the holidays, and it appears she has some experience. Unfortunately, because of her age, she is not allowed to work cases, but according to the chief, she still does. Everyone just turns a blind eye because of her status and her actual usefulness on scenes and in cases. Though she has not been involved in many murder cases, they draw the line there. The chief has offered to let his daughter 'take care' of young master while we work."

"That's ridiculous! I'm not going with some haughty girl-"He was interrupted by a book corner hitting his head.

"Who's haughty?" A dark brown haired girl with blue eyes walked around him. She wore a black shirt, dark blue skinny jeans and black tennis shoes. She was a little taller than Ciel and looked down at him.

"My dad told me I had to baby sit some kid? Are you it?" She asked Ciel.

"You do not need to baby sit-"

"He's the one. His name is Ciel, he is thirteen and if you get too close he bites, so be careful." Mia smiled as she shoved him forward.

"That's alright. My names Lizzy." She stuck her hand out to Ciel, but he seemed to be frozen for a moment. Sebastian looked a little worried and reached a hand out.

Oh! Lizzy, Elizabeth, wasn't that Ciel's fiancée or something? He got pretty agitated when I asked him for details and it seemed cruel to force him. Most of what I know comes from Sebastian.

"Excuse me?" Ciel asked.

"Lizzy. Or Liz. Or Becca. Or Rebecca. Whatever floats your boat. In fact, my full name is Rebecca Elizabeth Hyland, so go ahead and take your pick." She tapped her book against her shoulder. Ciel was silent for a while, and Mia stepped forward, patting him on the head.

"He'll go with Rebecca. Thanks for looking after him." Mia spun Ciel around, hugging him.

"Listen, don't lose your cool. This is a good opportunity too, get what information you can from her and the tour she takes you on. She's the chief's daughter, she's bound to know something. That's an order, Ciel. Snap out of it." She whispered into his ear and grabbed his corresponding hand, placing it on the back of her neck where the contract was. It seemed to work and he nodded, pulling his hand back gentler than before.

"Yes, my lady." He murmured into her ear, before he pulled out of the hug, following Rebecca.

"He said it again." Mia giggled.

AN: To avoid confusion, I should explain what's going on, uhhhh let's see, Mia Anderson is the girl who has the contract with Ciel, but has taken on the alias Ruth Taylor. Okay. There aren't any general pairings in here, though somehow, even though it wasn't intended, there is a slight pairing later. Well, one being Sebastian x Grell and another...

Thanks for reading!
