~~London, August 1894 Midnight~~

The nights in London were always dark and bleak, filled with prostitution, drunken sailors and pubs; the occasional bobby on patrol keeping the peace. Though in this era, there were creatures hidden in the dark that wandered about, seeking out prey to feast upon, willing soul's that would sell themselves away for a wish, a fancy, or revenge. In return, these humans lost their souls to the demons once their contracts were fulfilled, and were devoured, lost into the inky darkness of the world around them.

Though this was just one type of creature that was currently known to walk the Earth, there was another that was far more secretive, hidden, and reclusive. It did not look for prey for food, nor did it like being around the filthy cobblestone streets of this city it found itself in. A crinkled nose turned up at the wretched sound of some man gargling out his last breaths before them, a bloodied hand reaching out as they begged for mercy.

"Tsk, mercy is for the weak and faint of heart. You deserve none, filthy wretched person, you sicken me to my core." A sharp heeled boot came down and the man's head and a brief scream were silenced as his skull was crushed in a gory mess beneath the heeled boot. "What a mess you've made…" A muttered an indignant and obviously repulsed voice echoed down the dank and dark alleyway. With a swish of a cloak, the figure disappeared into the dark, the faint gleam of silvery eyes showing briefly before they vanished into the dark.

~~Phantomhive Manor~~

"Today we have a selection of Earl Grey from Twinnings Company. Paired with scones and some freshly picked raspberries and whipped cream." A hot cup of tea was placed in front of the young Earl Phantomhive, along with a delicately made plate of scones and raspberries, topped with a bit of freshly made whipped cream. The boy did not so much as smile as he took a sip of the tea, satisfied with the rich taste.

"Yes, that shall do nicely." The boy commented an air of nobility and grace about him.

"Also, you have a letter from the Queen that was delivered this morning," Sebastian commented, a slight, obviously fake smile on his face as he offered the letter on a silver plate.

"Oh?" The boy questioned, curious now. He took the offered letter and opened it with a letter opener from his desk, taking the carefully folded paper out of its sleeve. He frowned as he read the letter, then read it again before handing it to Sebastian. "It seems that there has been a string of horrific murders in London lately."

"Yes, indeed my young lord. Apparently, the victim's were all people who had committed crimes of some form or another." Sebastian commented, frowning as he read the letter.

"Arrange a carriage for London and make all of the proper preparation's at once."

"Yes, my young lord."

~~1 Week Later~~

Sitting outside on the edge of a rooftop, was a young woman in a soft, plain black and red dress, an old and intricately designed black violin in her hands as she played a soft melody, sad tones etched into the masterpiece. She frowned after a moment when the violin gave a slight screech, pausing to adjust and tune it some more. She eventually managed to get it tuned to her likings and resumed playing, a richer toned song flowing into the air. Noble folk and rich people listened to her music from the busy shopping district below her, some smiling, other's wondering where the beautiful music was coming from.

This was her usual spot at this time of the day, and most regular's found her music calming. Though today, her playing was disrupted when she spotted a certain butler in a black tailcoat walking alongside a young boy on the street below her. She hummed in thought for a moment, then the music changed to something different, a deep and dark tone edged into the music, which picked up in pace. The pair heard the change and the butler immediately looked up and spotted her, a curious look on his face. She merrily smiled at him, silver eyes flashing at him briefly as she stood up the black bow drawing across the violin's strings, drawing out a hypnotic, yet evil melody from the instrument. Immediately the nobles and people on the street's below started covering their ears, cries of pain and agony filling the air.

The butler was startled as his young master was now bent over in pain from the sound of the violin, and he covered his master's ears quickly before finding something to plug his ears with so he wouldn't be affected by the sound. "I wasn't expecting to see you here so soon, Sebastian Michaelis. Shall we have a little bit of fun?" She called out, smirking as she changed the tune, causing all of the people's eyes to turn glassy. They immediately started attacking Sebastian and the young boy.

"The Devil's Violin, how on Earth did you acquire it?" Sebastian commented curiously as he fought off the possessed people, while simultaneously protecting his master.

"That's for me to know and you to find out." She grinned, giggling softly as he frowned, knocking out most of the nobles with care without hurting them too severely. "Sorry to say that I can't stay around and play any longer, I just wanted to see what I was up against." She started to back away, only to find that the butler had vanished. "Oh...now where-!" She squeaked as strong arms wrapped around her from behind, startling her a bit.

"Is that so?" Sebastian's sultry voice whispered into her ear, causing her to blush at the close proximity.

"Don't think that this is over yet, just because you have me in your arms doesn't mean I'm going to submit so easily." She grabbed his arms tightly, flipping him over her shoulders and onto the ground hard enough to cause a small crater.

"Sebastian, this is an order, stop her immediately!" The young boy yelled at him.

"Yes, my lord," Sebastian said, his eyes flashing red. She blinked in mild surprise at this, then grinned wickedly.

"A demon, how fun. But I don't have the time to play right now. We shall have to continue this another time." She darted off across the rooftops, only to find Sebastian hot on her heel's.

"If you think running away is an option, your sadly mistaken my lady." He commented as he appeared in front of her.

"Who said I was running?" She smirked, then jumped off the roof and through a black and red swirling portal, which immediately closed behind her. "How strange a portal huh," says Sebastian as he sighed, returning to his Master.

"I'm afraid that she escaped my Lord. Please forgive my incompetence." He bowed with one hand over his heart.

"Fine. Did you learning anything about her before she got away?" He asked.

"Not much, just that she knows who I am."

"I see. Will the people she was controlling be all right?"

"The effects should be wearing off shortly, though I suggest we leave before Scotland Yard arrives. We wouldn't want to be caught up in their questioning, now would we young master?"

"No, we wouldn't. Let's head back to the manor, I think I'd like a cup of tea and something sweet. Afterward, you can tell me everything you know about what just happened."

"Yes, my lord."
