Black Oath
"Corrupt my mortals, I will give you my soul
―the contract of black oath,"

Alley after another, the white hair swayed in the air as if the mysterious woman was leading Ciel to somewhere unknown. Ciel chased after, ignoring his teammates yelling for him, however he could not easily ignore the demons that were constantly lunging on the fighter. Grunting with irritation and desperation of losing the sight of the woman he had been searching for years, Ciel sliced the bodies of the demons that were jumping for an attack towards the human. His breath became heavy as he used more and more energy on desperately running and fighting the demons off, and swiftly, he was becoming exhausted. Due to extreme tiredness, Ciel was not able to detect the existence of a demon that successfully landed a piercing attack on Ciel's back leg, its sharp claws jabbed into his skin as blood spurted out. Grunting with pain, Ciel stabbed the demon's hand as it yelled in agony. The demon's hand was jabbed into the edge of Ciel's dual bladegun, and as it hung loosely in the air, Ciel quickly shot another bullet as the demon busted with torment, rain of black blood splattering on Ciel's uniform.

Ciel walked in a jerky motion due to discomfort of pain in his back leg. With heavy breaths, he quickly hid his shadows in a dark alley as he tried to ease the pain, yet the blood was profusely gushing out of his skin. Beads of sweat were forming on top of his forehead which quickly rolled down his temples, only to be fallen on top of the cold cobblestone.

He couldn't dare himself to be let down like this; after a simple attack of the demons, he is already exhausted. How would he avenge his family's death in this condition? Then the thought of the mysterious woman fluttered back into his mind. The woman who reassured him as he was in an internal torture; she was the only one who offered a hand to the hopeless child and helped him to get back on his feet. He doesn't even know her name, her race, her voice― nothing. He could not define her.

She was just there… only couple feet away,

He thought to himself as he grunted with pain, the pain in his leg aching more as he shifted the position.

I need to… see her,

He does not know what he will achieve after finding her; meeting her once again was just a simple, pure mission he wanted to accomplish. However, even if he do find her, will she disappear once again like that night in the past? Or would he have the chance to talk to her, will he ever hear her voice? Thoughts about the mysterious woman constantly lingered in his mind, almost impossible to even erase her being trapped inside his soul. Effectively, the injured soldier's eyelids became heavier, as his breaths started to soften. Slowly, the tensed shoulders started to loose, and his visions started to blur― into the void sleep, he entered.

Pitch black. Ciel glanced about as panic started to rise between his fingertips, causing his hands to tremble in hint of fear. He couldn't see anything, or perhaps there wasn't anything. Either the lights were turned off, or there was no source of light.

"Hello?!"

He yelled out rather courageously, only to have his voice return as an echo. The male started to walk, then he started to run; even though he had no idea where he was going nor the direction he was running to.

Then at that moment, Ciel caught a glimpse of light from afar. With hopes growing inside his soul, he started to dash after it, not blinking his eyes even for one second in hopes of trying to not lose the sight of the light. As he approached the mysterious radiance, he realized it was a rich blue colored fire. There was no source of candles, wood, or anything, yet the fire was lit up rather brightly, flowing in the air. He reached out without thinking; it was then Ciel came to another realization, that the blue fire did not burn him, instead it wasn't even hot. Perhaps he lost his sensation of touch, yet he could feel his droplet of sweat trickling down his spine. He knows for a fact that blue flames contain more heat than red flames, therefore this was unusual, yet he was somewhat mesmerized by it. He had never thought fire could hold such beauty. In fact, he was traumatized by the walls of fire that had burnt down his past life, yet this fire was different Ciel tried to grasp the flames in between his fingers, he would place the palm of his hands under as if he was the one conjuring it, yet nothing worked to actually move the fire.

Then a thought struck him.

Is this a spell? A demon's spell?

Sudden panic started to rise within his alarmed soul, the fingers that were trying to attach itself to the fire started to tremble in fear. The midnight colored pupils of his eyes started to shake in nervousness. Ciel let out a silent sigh to relieve his alarmed soul, and cautiously he reached out for his dual gun blades that were attached to his belt located next to his hips. He slowly raised his weapons, one on the front and one on the back as his ears stayed perked up for any signals of demons appearing. However, although minutes have passed, there was no signs of demons. Not a single sound, not a single sight, and not a single smell. There was no demons around him. He let out a relief as he loosened his tensed muscles.

...At last, I've found her,

Ciel gently closed his eyes for relaxation and as he slowly opened them, the sight of the woman was in front of him. Just couple feet away, and in between them was the blue flame. He reached his hand out as he attempted to call her, yet he realized he doesn't even know her name.

"My name is Lu,"

Her angelic voice echoed throughout the void, resonating back into Ciel's mind as if she read his thoughts. Surprisingly, he wasn't confused or nervous. He was just content enough to finally meet her, even if this was a dream. Ciel gaped his lips in order to speak, yet no voice rang out; he was muted.

Slowly, the female's back that was facing Ciel slowly turned, her white hair that seemed to glow swayed in the air elegantly with each movement. As she faced Ciel, he couldn't do anything except to gape in shock. She had no face. The pale skin of hers just radiantly glowed; the crystal blue eyes, her petite nose, and her cherry-colored lips missing. Perhaps, this is a dream. Because Ciel cannot fully recall her physical appearances, his mind decided to rather erase her face. But how was he able to hear her voice? Years ago, when he had faced her in actual life, he wasn't able to hear her voice, nor acknowledge her name. After reanalyzing his thoughts, slight disappointment rose within Ciel, he wasn't able to figure out if this was just a mere dream, or reality of a demon's curse.

"Promise me a black oath…"

She softly whispered into Ciel's ear, gently brushing his midnight colored hair, tucking his long strands behind his ear.

"..."

She whispered something once again into his ear, yet it came out as a blur. He tried to focus his eyes onto her face, yet she was slowly disappearing. As confused as he was, he reached his hand out in order to stop her from disappearing, yet it was too late. Then the blue flame that was lighting itself slowly devoured her, burning her into nothing but voidness.

"Lu!"

He was finally able to speak, his desperation echoing into the blackness, unable to be heard by anyone.

With heavy breaths and sweaty palms, Ciel's eyes suddenly opened, releasing the feared panic that was trapped inside his eyelids.

A dream.

He wasn't able to tell if he was glad that it was a dream, or if he wasn't glad that it was a dream. He was able to see her, yet he wasn't.

From afar, he could make the sounds of guns being fired, swords clashing one another, and the sharp claws of demon ripping through the flesh of humans. Then the pain that was lingering in his back legs started to ache. He was back to reality.

At that moment, he heard a rustle from not too far, perhaps just mere couple feet away. Cautiously and silently, he raised himself up although this injured leg jerked in pain. He prepared himself for a sudden lunge as he placed his weapons before him. The demon was near. If Ciel can time the attack right, then as soon as the demon is about to pass next to the alley Ciel is staying at, he will be able to lunge onto the demon.

Closer and closer, the sharp claws of the demons echoed throughout the brick stones. Ciel held his breath, did not move an inch, until it was the right timing.

Now!

He turned his back then jumped a foot away from the demon, appearing himself as he aimed both of his gun blades toward the head of the demon.

Then he saw―

"I've found you,"

She whispered. The silky white hair that shined under the moonlight, the crystal cyan eyes that glistened with courage yet contained hint of happiness, and the same angelic voice that resonated into his dream. Her face wasn't a blur, her voice didn't come out as a mumble, and no blue flames devoured her. She was real. She was standing before his eyes like the night she had rescued him. He found the mysterious woman. He found the one whom he had loved for years. He realized, it was love.

Ciel's grip on his weapons started to strengthen itself.

She's a demon… I have to kill her,

He thought, the grip becoming stronger and stronger, yet he was unable to fire the bullet.

But I love her.

He thought as he lowered his weapon back down.

Lu let out a smile, not a mischievous one, but true smile contained with nothing but happiness. She gaped her petite lips, and the angelic voice echoed into Ciel's voice once again.

"I've lost everything. Before the embers of my life go out, promise me a black oath,"

The voice that was inside his dreams and the voice that is in the reality slowly completed the puzzle, becoming one, full voice.

"Will you become my royal strength?"

She asked as the chilly night wind played with her long, silky strands. Her crystal eyes held nothing but plea. She held out her hand, waiting for him to accept, or waiting for him to kill her.

Kill her.
Accept her.

Ciel's eyes shaked in nervousness, what was the right choice? Before he could give another thought ―

He accepted her hand.

White aura started to soared from the ground and gleamed before their feet. Blue flames started to make their way up toward the top of their head as the contract of Black Oath was activated.

He wasn't able to fulfill his mission. He wasn't able to avenge his family. He betrayed the human race. Instead, he had chose to fulfill the other, to go with his beloved. He had two questions but only had one answer. Perhaps this was the punishment for falling in love with a demon, perhaps the answer was already made the day of the bloody battle.

"I'll give you my soul for you,"

He whispered and she smiled.

With nothing but betrayal that has corrupted his heart toward the humans, the male slowly turned into a demon.

Diala and Demonio―
The Altar of Evil and Transcendence―

The contract of Black Oath is sealed.
