London was a disgusting place to live, but one of the best places to get rid of someone. Olivia stood out from the crowd as she meandered through the crowded streets. The first victim she was looking for was a young prostitute. It looked like a simple copycat of Jack the Ripper, but beneath her lips was an insignia she had seen before. Olivia took the photo of the once living prostitute to every whore house she came across, but only was pushed away in fear she would bring the authorities. She was growing tired of the simple one-word answers she was receiving from unwilling mortals. Olivia closed her eyes tightly before trying once more at the whore house closest to her. Pounding on the door, Olivia waited until the plump, older woman answered the door. The old woman's jagged teeth shown as she snarled at Olivia, "Oi, you be deaf? I said I ain't ever see-"

"Look," Olivia took a step closer, his crimson eyes glowing slightly as she used a darker force to get answers, "I'm only doing a job, lady, and if you don't give me answers, then i'm afraid there will be a punishment you don't wish to face."

The old woman trembled before she emitted a puddle of urine beneath her dress. Olivia sneered at the rancid smell before taking a step back in disgust. However, to her surprise, the old woman clammered inside before returning with a waste-basket full of clothes, " 'Ere, these be hers! Tha' bitch used to work 'ere but she quit a week ago. Said she got herself a rich gent that wanted her as his harlot in his home."

"Does he live around here?" Olivia questioned, only receiving a shrug from the old woman.

It was the best lead she had gotten all day and it was enough to keep her going. Olivia stacked the clothes in the carriage, just in case she would have to get further evidence. Once she closed the door to the carriage, she saw through the corner of her eye that she was being watched. It didn't take her long to see that it was a member of the Scotland Yard. Did they even know who she was? She didn't have to guess to know that they probably already did. Olivia walked to the head of the carriage to see Bard taking a nap, she radiated a burst of energy that woke the blonde man, "Bard, do me a favor and drive the carriage a few blocks. This place doesn't seem safe."

Gruffly he obliged as Olivia entered the carriage before making a quick escape into another crowd. She wanted to lose the track of the Scotland Yard so that she may continue her search. For the most part, most of the victims were prostitutes, but some where upper-class young men as well that bore the insignia on their bodies. However, one last victim stood out from the rest. One body didn't have an insignia on their skin or beneath their lips. Olivia went to the scene of the crime, a cellar of an old, burnt home. She searched every crevice of the cellar and couldn't find any insignia that might've been over-looked. After searching for what felt like hours, Olivia stood in the center of the room as she tried to recall what could have happened that very night. She closed her eyes tightly, then reopened her eyes to reveal that her eyes were fully glowing as a black aura surrounded her. Her vision revealed the location of the insignia and possibly the whereabouts of the killer:

The young man followed the person to the cellar, seemingly excited as well as curious. As soon as the two people reached the cellar, the young man stood in the middle of the room and glanced around for something. The other person waited until the young man was just about to turn to them when the young man was stabbed in his neck. He had died rather quickly, and the other person placed the body against the floor. The body was then cut precisely from the sternum down to the pelvis where the killer began to etch something within the body before expertly sewing them back up. The killer left the rusted, bloody knife in the lad's neck.

"He wants to be found," Olivia spoke aloud as she came out of the trance.

She quickly left the cellar to find the morgue, hoping to find the body in hopes of further examining it. As soon as she emerged into the cold air, Olivia came face-to-face with Sebastian. These surprise meetings were growing tiresome each time this happened. Olivia pulled herself out of the cellar, "My brother's watch dog, what a surprise."

"I am simply doing my job as a butler, vessel of Lucifer," Sebastian answered, the last phrase he stated was coated in accusation and silk as his eyes revealed that he knew the truth.

Olivia hesitated, she hadn't expected for someone to find out. She waved off Sebastian as she walked passed him, "I haven't the slightest notion of what you're talking about."

"Your brother sold his soul to a demon where in the end he will be my next meal," Sebastian boldly stepped closer to her and snatched her wrist, yanking her back to face him, "You sold your soul to an even older demon, the ruler of hell. I'm surprised of all people and mortals to choose from, he chose you to be his vessel. Tell me, what happens when your use of his abilities is completed. Does he feast on your soul as well?"

She pulled her wrist from his grip as she staggered back a step. Her eyes glared angrily at Sebastian, how could this simple demon find out!? Olivia opened her mouth to speak, but Sebastian interrupted, "You are stronger, I will not discredit that, but you were a mortal that came upon great power and, like any other mortal, you're careless with it. Any demon with sense could sniff you out when you have your guard down."

"You will keep quiet about my secret," Olivia growled, her panic began to rise and she could feel the urge to use her abilities were growing as well, "You won't say a word to Ciel at all about this!"

Sebastian then appeared mere inches from her. She could still smell her brother on his body. His hand then tilted her chin upward as she tried to fight him off, "You're still just a woman, even with the soul of Lucifer residing inside you. A careless, thoughtless woman that cannot control her emotions."

An idea then popped into her mind. Olivia remained still as she thought of the killer, the person was luring those easily fascinated by money and finer objects. Prostitutes and those of simple greed were open targets. Thoughtless women and careless men. Olivia then looked up at Sebastian, "I'm going to need your help. I have a hunch that the killer isn't a regular human."

Ciel sat in his office, it was rather strange that Sebastian was running late once again while pursuing his sister. His thoughts were at war in his mind, trying to give reason for his butler's tardiness as well as rationalizing the notions. Sebastian had been hounding him about taking him in a different sense rather than just a butler and demon contractor. Ciel relaxed in his armchair, he was becoming too trusting of Sebastian. In the end, the butler was still a demon hell bent on feasting on his soul once Ciel's investigation towards the death of his parents was revealed. Until then...Ciel wanted to keep Sebastian as his own lover without sharing him with anyone.

The young lord stood up. He wanted to find Olivia and Sebastian immediately. One problem: Olivia had taken the only carriage. However, there were still other horses in the stables...

Against Finny's and Mei-rin's objections, Ciel rode off on one of the fastest horses he owned. He was barely able to keep a good hold on the steed, but he managed. Ciel saw the sun sinking deeper and deeper into the night sky. It only made him push the horse to go faster so he wouldn't have to travel in the darkness of night.

"This should work," Olivia fixed her cleavage in the old clothes of the dead prostitute.

"You were rather quick to wear those clothes," Sebastian noted as he watched Olivia emerge from the carriage, "Are you certain you'll find the killer in London on your first night dressed as a whore?"

"Positive. The last victim was last week. Unless no one found the body, that's the most recent murder," Olivia answered before motioning towards the napping Bard, "He needs to go. The less people involved the better."

Sebastian nodded slightly before waking the surprised Bard and having him drive off back to the manor, saying that Olivia was sleeping inside the carriage. Once it was just the two of them, Olivia approached Sebastian, "I don't expect you to protect me, I don't need it, but just in case my hunch is right I may need some assistance."

The two stood in silence for a moment before Sebastian disappeared. Olivia felt little comfort in his unwilling nature towards her. Then again, he was a demon employed only by Ciel. Sebastian didn't have to take orders from her. Olivia casually walked in the dim light provided by the street lanterns. Some were already blowing out while some light was emitted by the passing whore houses. She looked to the sky to see stars, the sun had already fallen. What was worse was that she couldn't scent Sebastian anywhere near her. For all she knew he would try to kill her again.

Olivia continued to walk aimlessly, she was starting to doubt that the killer would be looking for a new victim anytime soon. She was just about to call off the trap when she picked up the sound of hooves against the cobblestone. Not only that she also picked up Ciel's scent. Her panic rose as she thought of her brother in the dark streets of London with a killer on the loose. Did he not know of the danger that place them in? Olivia went to the shadow of an alley to hide from view. She peeked out slightly to see Ciel on a horse galloping into London. He must not have seen her because he rushed right passed her.

She turned to follow the alley until she came face-to-face with a masked figure. Then, a sharp blow to the stomach sent her to the ground. Blacking out, Olivia felt the taste of mortal fear she hadn't tasted since before she gave her soul to Satan.

Ciel held onto the reign on the horse as he walked the streets of London. He felt foolish for running after his butler, especially since he hadn't intended on becoming emotionally invested in the demon. But the thought of Sebastian close to his sister only made Ciel want to find either of them sooner. He turned a corner and found Sebastian, toying with a stray cat, "I had thought you would be doing a task instead of playing with a dirty cat."

"I had until I became part of the plan," Sebastian answered, "Your sister managed to read the letter even before yourself."

"W-what!?" Ciel couldn't believe what he had just heard, "But the seal! It was unbroken!"

"In any case, she has found the killer and will be splayed open soon," Sebastian added as if he were speaking of the weather.

Ciel was speechless. His hate for his sister disappeared as he thought of her lifeless body in a ditch somewhere. As much as he resented her, he couldn't let her just die without saying anything to her. Ciel scrambled back onto the horse, "We need to find her now! Sebastian, I order you to find Olivia and stop her death-...I thought you said she couldn't die."

Sebastian's cold eyes looked to Ciel as he climbed onto the horse and seated himself behind Ciel, "There may be reason to believe that the killer is not human."

There were too many questions in Ciel's mind: how could there be a risk of Olivia's death if even Sebastian couldn't kill her? How did she manage to read the letter from the Queen when Sebastian had brought him the letter personally? Something wasn't adding up. Ciel remained silent as Sebastian had the horse gallop following Olivia's scent all the way until they reached a sizeable house in the middle of the higher class part of London. None of this was making sense to Ciel. He leaped off the horse and ran up to the metal gates, the manor looked positively abandoned, "Olivia wouldn't be in there."

"This is where I can sense her," Sebastian commented as he picked up Ciel bridal style then leaped over the gates.

"Put me down!" Ciel struggled to the ground, but snatched Sebastian's hand, "Where were you all day? All you had to do was to follow her and tell me what was going on, and now you're helping her catch a killer I was supposed to catch? If you're playing on both sides then-"

Sebastian silenced Ciel with a soft kiss. Ciel wanted to fight back, but only felt Sebastian press harder against his lips. It was thankful that they were alone in the darkness so no one could see them. Sebastian slowly pulled away from Ciel and smiled, "Young master, you really should stop worrying so much."

Ciel looked away, hiding the blush tinting his cheeks, "We need to find Olivia before anything happens."

The young lord was picked up by Sebastian as the demon burst inside the front doors. Everything was coated in a few layers of dust, but there were feet tracks that looked recent. Ciel left Sebastian's warm arms and followed the tracks until the foot prints led to a grand staircase. Running up the stairs, Ciel could hear bangs and clashing metal. He feared that Olivia was fighting for her life until he heard a high pitch scream somewhere in the darkness. Ciel's heart pounded in his ears as he thought of all the words he had said to Olivia, wishing he could take them back just to see her one last time. The fear of losing his last relative, ever since Madame Red's death, overtook him. He needed to see Olivia alive again, he needed to save her.

Then, another scream wailed into the darkness. Ciel found the doors that were hiding the scream and bashed them open. The sight in front of him bore into his mind. An older man was suspended in the air with nothing holding him. He was stark naked with fire burning into his flesh an insignia he had never seen before. Below the burning, screaming man was a young woman coated in flames. Her hand reached up towards the old man, and it looked like she was the source keeping him above the ground. Ciel couldn't move to see who the female was. He then watched as the young woman's head turned 180 degrees to turn and see him. Their eyes connected. She was Olivia. Ciel watched as she turned her head another 180 degrees to continue burning the insignia on the old man. Then, the room began to spin and Ciel felt the urge to vomit. He rushed to the corner of the previous room and threw up the contents of his stomach onto the ground.

He had seen many sights in his prime days of youth, but none such as horrid as this one. What he had witnessed didn't make any sense at all! Ciel wanted to scream in fear, to have Sebastian kill the woman that claimed to be his sister. He had never heard the crack or snap of bones twisting in a way that should never have been twisted before.

Olivia watched as the man twitched as she dropped him to the ground. He was the killer alright, but she wanted to know his intentions. She popped her neck back into place as she approached the broken-legged man, "Barnaby Ashland of Ashland Industrial Corporation. You've killed numerous prostitutes and prospective young men for what? A few moments of carnal pleasure and murder?"

"N-n-no," he sputtered as blood curdled into his mouth and escaped his lips, "I was trying to summon...to summon you. You're the anti-christ we've all been waiting for."

She hesitated for a second before placing her hand on her head. Was this what people were referring to selling one's soul now? Olivia reached down and gripped his neck, forcing him to stand on broken legs. He whimpered in agony before she slammed his back into the nearest wall, "My..dark lady... Let me serve you and pay..tribute to Satan."

"The insignia you used," Olivia forced him to stay on track of the interrogation, "You used the insignia that's used as a symbol of ghosts and..phantoms. You were using that sign as a way for me to track you down. Now here I am, Barnaby, what did you want from me?"

He spattered more blood, some getting on Olivia's torn sleeve. She dropped him to the ground, the cracking sound of bone becoming less bothersome. Barnaby looked up at Olivia as he chuckled, blood trickling down his cheek, "Those who follow the Dark Lord knew the day you would sell your soul. We waited and followed orders, knowing they would bring you right to use. You, our Dark Lady, have finally come back to us. You will cleanse the wretched souls in darkness like your parents-"

Olivia's eyes oddly wide before she emitted a bone snapping energy that sent Barnaby crashing against the wall, crushing him slowly. The energy grew more and more powerful as Olivia's voice turned into a deep growl, "Don't ever speak of my parents again."

Barnaby gurgled more blood as the insignia burned against his flesh reacting to Olivia's energy. He moaned in agony as his eyes darted to Olivia, "I..know...who.."

SNAP

His neck snapped in half, some of his bones poked out of his flesh. Olivia's energy died down as she stood motionless. She hated herself for killing the source of information that might have given the names of those who murdered her parents, but she didn't want to keep him alive long enough. Olivia stared down at the lifeless corpse. There was another matter she had to deal with. She turned to see Ciel walking down the steps, obviously shaken as Sebastian stood at the top of the steps gazing back at her. Olivia watched as Ciel kept his back to the wall, the look of fear was in his only revealed eye. She didn't have to ask as to why he was so frightened.

"Who the hell are you!?" Ciel growled as he pointed a finger at Olivia, "You are not my sister!"

"Ciel," Olivia spoke softly as she sat on her knees, her dress was almost torn off of her body, "I didn't want you to find out like this."

"If you are my sister then stop treating me like a child!" Ciel yelled louder, "I have done far too much to be treated like some snot-nosed kid that hasn't seen what I've seen!"

Olivia now understood. She had deluded herself to believe that Ciel had not fully changed. Now she could see that she had been wrong. Ciel was no longer the little brother that ran to her when she arrived from school. He was no longer the boy that enjoyed their games. Her little brother was no longer a foolish child hidden from reality. It broke her heart to know Ciel has witnessed the cruel realities of life and has been tarnished by sullied hands. Olivia raised a hand towards Ciel, she bent even more so towards Ciel as if attempting to grasp what was left of her brother, "Ciel...I'm so sorry."

She watched as he hesitantly took a step towards her, then another. Ciel was then just in arms reach of her. He bent down on one knee and grasped her hand. The two gazed into the other's eyes. Olivia felt the connection immediately. She may have lost her kid brother, but she did not lose Ciel. In that connection she felt his distrust towards her. They were allies in the middle of a war around them, a temporary truce between them that would have to work for now. Olivia stood, shielding the corpse behind her so that her brother would not lay witness to her damage.

"Young master, shall I prepare a late supper?" Sebastian spoke up, ending the silence in the hollowed room.

Ciel looked up at Sebastian, feeling something in his heart beginning to stir at the sight of the demon. He nodded and guided his sister up the staircase. Before they reached the front doors, Sebastian stopped and took off his coat to hand it over to Olivia. She paused for a moment, as did Ciel, before taking the coat to put around her shoulders, "Thank you."

Olivia sat in the darkness of her room, contemplating on the evening's events. She felt as if she had displayed her naked body to Ciel when revealing a secret she did not want to show him. Even in the safety of the darkness, where her own demons clamored within her mind, Olivia felt little peace. Barnaby's words haunted her. 'The Dark Lady', or whatever he called her taunted her even more. The title poked into her conscious as she thought of her parents and how they perished. Fire cleansing their souls...nothing but nonsense. They were murdered. Olivia felt a sudden tightness in her chest. Her sole purpose to having these abilities was to enact a revenge so powerful on the murderer that the world would be haunted by her power for years to come.

A knock at the door woke her from her memories. Olivia pulled on a small robe to cover herself as she opened the door slightly. Sebastian's face was illuminated by a simple candle as he stood outside her bedroom. She looked around him to see he was alone, "Why are you not with Ciel?"

"He is asleep," he answered, "I have a few questions of my own."

Olivia allowed Sebastian into the darkness of her room. For them, the darkness didn't hinder their sight. She sat on the stool in front of her vanity as Sebastian blew out the candle, placing the gold stopper on her vanity. They basked in the darkness together until Olivia spoke up, "What I must do is keep Ciel safe from whoever has murdered our parents."

What she kept to herself was that she also had to keep Ciel from being devoured by Sebastian. Her eyes swept up to Sebastian as he met her gaze. She could feel Sebastian looking her over, sensing and tasting the power within her. Then again, he wreaked of sex and lust, every pore of his body was dripping with desire. He was a natural predator; beautiful to the eye until he claw them out. Olivia stood up as well, allowing her robe to glide to the floor with ease. She went to her bed and went beneath the covers before turning away from Sebastian.

"You are my brother's demon to use," Olivia spoke as she rested against the soft sheets and pillows.

"I am loyal to the Phantomhive family," she heard Sebastian's voice become closer, "I serve the Phantomhive family until I can feast on Ciel's soul."

Olivia sat up, mostly to protest, until she saw Sebastian standing right next to her bed. A woman of good sense would have shoved his demon tail right back out into the hallway. The image of Ciel displayed into her mind that caused her to waver for a second. She contemplated the situation and the choices in front of her. Olivia then sat on her knees on the bed before reaching out and gently clutching Sebastian's clothing. For the first time, she felt something that hadn't experienced before. A warmth inside her emerged as she watched him take off his gloves with his teeth before his demonic eyes glowed in the darkness. His face loomed closer to hers before he had her laying beneath him, his lips crushing her own.

Ciel sat up in bed as a cold chill waved through him. He glanced beneath him to see a pool of sweat, something must've spooked him. When he was about to ask Sebastian a question, he noticed his butler was no longer laying besides him. Ciel pulled the sheets to his bare chest. He hated waking up alone. Curling up beneath the sheets, Ciel waited in the darkness for Sebastian to return. The bright, full moon gave some light to the room as Ciel continued to wait and wait for his demon lover. All the while he waited, his eyes slowly began to close as exhaustion took over. Why did Sebastian always leave after they made love? Ciel covered his face half way, some part of him still embarrassed that he was sleeping with his butler. Another part of him felt self-conscious that Sebastian was just using him as a means to relieve stress.

"Damn him..." Ciel turned away from the window, "He won't do this again..."

That was a lie and Ciel knew it.
