"And I demand
You put my heart back in my hand
And wipe it clean
From the mess you made of me
And I require
You make me free from this desire
And when you leave, I'd better be the innocent
I used to be"

Prologue

1906

Vatican City, Italy

Ciel

A dark smile curled Ciel's lips as he ran his tongue over his fingers, licking them clean where they were slick with dark blood, staining his pale skin crimson. The air was full of sharp crackling sounds and the destructive groans of brick and mortar tumbling towards the ground, loosing their grip and landing in a blazing heap below. Everything was bright, dyed with amber and gold where flames licked and destroyed, tearing everything down. Screams of terror and pain echoed everywhere, ringing in the ears of the demons that watched on, bemused. Perched on the edge of the building opposite, one leg crossed over another, Ciel watched the humans scurrying away with a longing and lustful hunger. That last meal simply hadn't been enough. No where near enough.

"Sebastian, I thought I ordered you to find me a soul that would be satisfying. This was pathetic, meagre even. Tasteless wretch."

Sebastian gave a mocking smile, chuckling. He shrugged playfully. "This is the best I could find. What a greedy master you are, danna-sama."

Ciel tsked, giving his butler a glare, his gaze sharply turning back to the building. His magenta eyes, serpentine and menacing, narrowed. In his chest his heart gave a heated stutter, the image of that dark smile burning into the boy's mind. Ciel felt his lungs expand, filling them with the fiery, smoky scent of the man beside him. The flames that they had started were beginning to recede, dwindling to tiny flickers compared with the raging flares that had captivated their audience. How dull. That meant that the time had finally come and now Ciel would have to set his plan into motion. Stealing a final glance at Sebastian under his lashes -a motion which he knew the butler saw and always used as an excuse for sarcasm- the younger demon took him in from head to toe, feeling his lips twitch at nothing in particular.

"Find something you like?" He asked, reaching out to skim his finger over Ciel's cheekbones. The teen slapped his hand away, fighting the heat that was blooming all over, the skin tingling where pale fingers had traced him. He stood up abruptly, altering his expression into one of arrogant annoyance.

"You touch me too easily." Ciel stated, "Stop saying such perverted things."

Sebastian smirked darkly, his scarlet eyes fixated on the only prey that had managed to get away from him in all the centuries he had lived. Ciel felt as if he were being stared at right into the depth of his soul when Sebastian looked at him that way, that his misgivings and the cruel intentions he had would unravel of their own accord, spilling all his secrets into the air. He didn't like it. Inhaling deeply, he flicked his head back and stared at the clouded sky.

"I'm bored." He started, his voice calm and even, as strict and unyielding as it always was. The teen was unsurprised by the butler's lack of reaction, prompting the man once more with; "I want to play a game."

Sebastian tilted his head curiously, sighing. "But, my lord, all of your pawns appear have run away. What do you hope to achieve by tormenting the dirt?"

As expected, Ciel had received the kind of response that was usual. The setting had been purposefully arranged so that no human should be around, giving him an reason to do something other than cause them havoc. Stupid humans -sometimes they could be so blind and dense.

"I want to play hide and seek." The younger demon demanded. His butler's eyes widened, but they were full of amusement.

"Hide and seek, master? Aren't you a little old to be playing such a childish game?" -Ciel gave him a glare, a most adamant and irritated one before the latter sighed.- "I suppose I am to play the seeker then? But, I wonder… what shall I receive if I find you this time? You know I never fail at this game."

You never fail me at any game, Ciel added silently, his lips quirking up in challenge. "Is finding me not reward enough?" He asked, "You will find me because that is my wish -I have no need to bargain with you. Now, turn around and count to a hundred. Hurry, children can be very demanding about their games."

The other demon's eyes narrowed for a moment, a flicker of something in them the teen couldn't understand, but it was quickly brushed aside and the butler did as asked, closing his crimson eyes with a large grin on his lips. Clasping his hands behind his back, Ciel strolled backwards feeling a bubble of dark and amused giggles in his throat. He fought to contain himself as he walked right off the edge of the building and plummeted to the street six floors below, slicing through gravity. Wind whistled past his sensitive demon ears, his blue-black locks fanning up until he instinctively forced his body to slow in it's descent mid-air, a few feet above his target, the balls of his feet touching down gently. He didn't need to glance back to see if the butler was still counting because he knew that the demon would not dare defy him, so he continued walking, taking a sharp turn down an unmarked street and disappearing in a flurry of black, blue and deep purple butterflies.

Reappearing once more, Ciel was in a room that held no light, nor life, just an endless span of darkness all around him. Lifting his lashes, the blackness suddenly sparked to life, the ground under his feet shaking. Lavender light burst forth from a tiny crack, grinding through the earth. It ploughed it's way in the motions of what appeared to be a circle, huge and startling. Waves of power rippled from the one whom controlled this energy, watching with a smirk when the final details began to etch themselves in. Before him, a giant pentagram was inscribed into the floor with solid walls reaching to unknown heights. It was like looking through running water, trying to see through the outer circle - a circle that consequently it's master walked into without hesitation, rings of magic erupting from under his feet with every step, cracking the ground. Ciel's hair sought to reach new lengths, whipping out above his head when he passed over the border and positioned himself in the centre. His eyes -one the colour of blood and the other a deep lilac, an exact replica of the symbol under him burning into his iris- flashed and pulsed, fluxing to a whole new level, erupting the child into a fit of eccentric laughter. He liked this feeling, the feeling of limitless power at his fingertips, running through his veins. It brought him to new depths and allowed him so much more.

You say you shall never fail me, Sebastian. You imbecile of a demon -do you really think I would let you win again? I grow tired of losing, there is no possible way I can be defeated this easily. I shall show you the true meaning of hiding.

Another terrifying chuckle escaped his lips.

No, you shall not find me this time, I shouldn't think. Not for many, many years to come.

The boy snapped his fingers, his body twitching from the spasms of amusement that claimed him. His hands shook vigorously as he slipped the blue diamond ring from it and took it in his palm, levitating the tiny object a few feet above his skin. It was seized by a lash of energy along with a letter the teen had stashed into his jacket. Swept up on the back of an ebony butterfly, the creature awaited it's instructions patiently. However, it would receive them until his goal was accomplished. With a sadistic grin and thoughts of the horror and irritation his butler would soon feel, Ciel took a step back, into the innermost circle, upon he would have no return. "Let it begin." He said finally, a chant made of evil and demonic wording falling from his lips.

Sebastian

Sebastian stopped. Every thought he had been processing at that moment froze. Every single pondering curiosity was shredded to insignificance as he noticed something very, very troubling.

He could no longer sense his master's existence.

It had been there but a few moments before, he knew that. As closed off as the boy yearned to be from his butler, Sebastian was always at least able to feel his life force through their bond. He was able to always track the proud teen's location. However, that was no longer the case. Instead, he felt nothing, nothing at all.

It was almost as if the child had disappeared off the face of the earth, which was impossible. Anger and irritation erupted into the demon at once, an alien panic and growling annoyance finding it's way up his throat in the form of a vicious snarl. He tsked, removing the white glove from his hand in haste. To his relief the mark he sought -the mark that bound contractor to contractee- was still there, which meant he was still not free from the boy. Their contract was still being upheld and that meant the boy's soul was still on this earth. Strangely though, the body that held it, did not. No matter how deeply he rooted within himself, his powers, his very being, nothing seemed to emerge and frankly, it was worrying. There couldn't be found a slither of Ciel's essence. Very real and very odd tingles of warning were beginning to run along Sebastian's spine, alerting him that something was very wrong, and he didn't like it one bit.

Master, what are you up to? Not even a child as troublesome as you should be causing me so much concern. This is most certainly not natural.

Suddenly something flickered near the demon, a very tiny and very faint reminiscent dot of familiar energy. It was hardly even there. If Sebastian had not seen the fluttering black butterfly out of the corner of his eyes, he would have questioned whether it had been there at all. It was one of his master's creations, that much he knew, because it seemed to like toying with him as much as the teen himself did, manoeuvring around his fingers for a couple of minutes until it settled of it's own accord in the middle of his palm.

"You have a message for me, master?" He asked it.

The butterfly twitched, then abruptly broke down, twisting and morphing from it's original shape into that of something flat, with a minuscule circular object atop. Remnants of the creature shrank into the smallest piece, absorbed into the shining facets of a brilliant blue diamond, set within a silver band. Sebastian felt his eyes widen in shock.

The master's ring?

Holding the tiny jewel between his thumb and forefinger, the demon's brows came together, eyeing the letter he had also received. The ring was slipped into his pocket for safekeeping and immediately, he tore into the expensive paper, pulling free the note and scanning the contends hurriedly.

By the time his eyes reached the bottom, the demons eyes had fluxed a ferocious pink, his expression hardening and turning colder than a north pole glacier. The piece of paper held only a single line within it, but it was a line that drove the demon to the edges of his sanity.

The game has begun.

Attached to the letter was a scrap of paper from a book, one with inscriptions and words on it that Sebastian never in a million years would have thought the boy would use. It was a spell to exorcise one's soul and send it on to it's next life.

The demon's eyes flashed and with that, the notes burst into flames, crumbling to nothing as he withdrew the ring from his pocket once more. Where only two minutes before the jewel had been a magnificent sapphire, it was now a deep amethyst shade, Sebastian's own demonic insignia brandished within.

So you cast away your soul and locked away your power. Do you wish to challenge me master?

Dropping the newly-reformed piece of jewellery back in to what would be it's safe haven, Sebastian checked his pocket watch, his demonic gaze almost burning a hole into the metal.

"Well then, it looks as if I should get started then." He grumbled bitterly, "Something tells me that I shall be doing more overtime than I expected. That accursed little brat."
