Note(s): General warnings: slight angst, cursing, (maybe) slightly OC-centric, (maybe) slightly OOC characters, (possible) spoilers, and Rated T — possibly going to elevate to Rated M. This could be a slight crossover with Final Fantasy VII for stealing Vincent (though looking mostly like he was during his time as a Turk while having the same personality as the game) and any other anime/game I want to use.

Chapter One: Enter the Raven

The day for Ciel Phantomhive started out as a pretty normal day; though he had just gotten away from his fiancée, who could be rather annoying — despite the fact that he still cares for her deeply.

Ciel was a rather short, twelve-year-old boy — only being around five feet tall. He had a fair skin tone and was somewhat thin. He had dark, navy blue hair with his bangs covering most of the upper-right side of his face, and his left eye was dark sapphire-blue. His right eye was normally covered by a black eye patch, not covering his eye when he slept or if he deliberately took it off. He sported two rings, one worn on his left thumb that had an ornate silver body holding an emerald-cut blue stone while the other worn on his right hand was a gold band with the Phantomhive family crest emblazed on it. As a noble, he wore expensive clothing — a dark blue, thigh-length jacket over a black vest and white dress shirt, a black ribbon tied in a bow, black pants, and dark brown dress shoes.

However, he had just received a letter from Queen Victoria concerning the various murders of prostitutes. He was ordered to find Jack the Ripper, the murderer's given nickname, and take care of the situation. This wasn't the part that offset him though — it was the fact that the queen had said that he would be working alongside her Raven, a title for the head of another noble family that worked in London's Underworld.

He had ordered Sebastian to look into the Queen's Raven — he didn't want to come into the situation without knowing exactly who he had to work with. Apparently, the title of 'The Queen's Raven' belonged to the noble family of Schiffer, a close friend of the Barnett and Midford families. The Raven had a similar job to his, but unlike the Queen's Guard Dog, who will (sometimes) apprehend the offender for Scotland Yard to take care of, the Raven automatically kills the offender after getting answers for the queen.

"My lord, the carriage is ready," his butler reported, just coming into his study. "All that is needed is to pick up the Queen's Raven before we head to the town house."

Sebastian was a young, handsome man who appeared to be several years older than her. He was around thirteen inches taller than Ciel, making him six-foot-one, with a lean, fairly muscular build and a pale skin tone that had a grayish tint to it. He had shoulder-length, raven-black hair that had his bangs framing his face and a thick strand swept in between his eyes, and his eyes were a dark red color. He wore a white dress shirt under a dark gray vest, a six button double-breasted swallow-tailcoat, black trousers, and he also wore black dress shoes and white gloves. He had the Phantomhive family crest on his shirt cuffs and black tie. He also sported a silver pocket watch with a chain, as well as a chained silver lapel pin that bore the same family crest.

"Very well," the young nobleman replied, getting to his feet and grabbing both his top hat and walking cane — even though he didn't really need it. "We'll leave now then."

"Certainly, sir," Sebastian said, bowing.

The carriage ride was a mostly quiet one; the only times either of the two talked — even though Sebastian was driving the carriage — were when they were discussing the job/background of the Schiffer family or things concerning the Jack the Ripper case. It was about fifteen minutes later when the coach stopped and the butler opened the door for his young master to get out, meeting the sight of a rather beautiful mansion.

They went up to the door, the Demon knocking on the door twice before it was opened by one of the house's servants.

The servant was a man who appeared to be in his late twenties and was about six feet tall. He had pale skin and a lean, fairly muscular frame. He had crimson eyes and shoulder-length, black hair with most of his bangs parted to the left and covering some of his left eye. He wore a white, long-sleeved dress shirt under a black vest and black jacket, black pants, and black dress shoes. He also wore a black tie around his neck and black gloves covered his hands.

He bowed in respect towards them — more specifically, Ciel due to his title — before straightening himself. "Lord Phantomhive, we've been expecting you," he said, his voice low and scratchy though it was as if he was supposed to speak that way. "Vincent Valentine, butler of the Schiffer household."

They heard a slight clicking noise behind them, and the two visitors looked over to the main stairs as Vincent stepped aside. Just coming to the floor and walking towards them was a noblewoman a couple years older than Ciel.

She appeared to be a beautiful, fragile teenager around the age of fifteen who was a little taller than others in her age group would be and had a lean, lithe build with a nearly translucent-like skin tone. She had long, night-black hair with a slight silver sheen, making her locks resemble the night sky, and her bangs covered all of her left eye while the pieces that were left framed the right side of her face. Her visible eye was a deep green, like an emerald, with a slit-like pupil. It was barely noticeable, but her left eye was covered by a black eye patch. It had a chain as one of its straps and went to wrap around her neck like a choker, which was partially covered. She wore a black shirt with long sleeves and an up-turned collar, black pants, black combat boots that were secured by black buckles, and she also wore black gloves that only left the index and middle fingers exposed. Over her shirt she wore a thin, ankle-length black coat, and she also wore a ring with an intricate silver body holding an emerald-cut, dark green stone.

"Lady Schiffer," Vincent said, bowing respectfully to his mistress, while a slightly shocked expression appearing on their visitors' faces; after all, it wasn't every day that you see a woman, especially of a noble family, wear pants which were meant for males.

A green, cat-like eye looked towards the two standing near the door, as if analyzing the two. "…Lord Phantomhive and his butler, yes," she asked, though it was said more like a statement, her voice low yet smooth and melodious — perfectly fit for a noblewoman.

The young Guard Dog quickly regained his composure. "That's correct," the boy replied. "I am Ciel Phantomhive, Head of the Phantomhive family." He then gestured lightly to his servant. "This is Sebastian Michealis, my butler. We will be working together on the orders of Her Majesty, but we'll have to be working from my family's town estate," he stated. "Is this acceptable?"

Despite knowing that he was only saying this out of formality, she nodded once anyhow. "Vincent," she began, her gaze moving to her butler, "you shall accompany me," she ordered. "…I have a feeling we will need you later on."

Standing straight, he gave a graceful, flawless bow. "Yes, my lady," he replied before opening the door again, allowing them to leave the manor.

"We shall ride in my carriage to the town estate. Is that all right," Ciel enquired, and she nodded.

Sebastian, being the closest to the carriage, opened the door and assisted the young woman and his master into the carriage before climbing into the driver's position.

"Mr. Valentine, you may sit inside with your mistress if you wish to; I have a feeling that she would feel more at ease with someone that she has been acquainted with," the Phantomhive butler said, bearing a polite smile.

Not changing his basically emotionless expression, something that his employer seemed to share, as he replied, "Lady Schiffer can handle herself fine, and even if she can't handle the situation on her own, I will be there to defend and assist her should she call for it."

Sebastian's polite smile seemed to become slightly more genuine. "That's a very good answer, Mr. Valentine," he commented as the other butler sat next to him though with a bit of distance between them, of course. "Your mistress has a very good butler."
