Chapter Text
*Flashback*
The darkness of the throne book surrounded you, as guards hissed and growled, trying to scare you. You glared back at them which actually made them jump away from you in fear. You were a powerful demon and everyone knew all about you, especially how dangerous you were. So the reaction from them was very expected.
You looked forward again to the giant figure sat in his equally giant throne scowling down at you clearly displeased. His skin grew red like fire in different places, constantly changing around his body. It was said that the red blasts was the energy from hell bubbling within him, and that it was the very lava under you that flowed through his veins.
"Kill my guards and I'll kill you. Unless you kill a useless one, of course." his deep voice filled the dark and empty room. You could sense the other demons in this hall, almost all of them had shown up before you had got here. All were silenced by the mighty being before you.
You watched as he tightly gripped his arm rest. His hand so strong, he cracked the gold that embodied it. You sensed his anger increase and simply stared towards him as lava began to fall down the walls of the building. As it fell, it would land in the giant lava pool below creating bubbles of heat that popped and sent chunks of lava flying.
You could sense fear like it was dripping off the guards all around you, they say that demons don't have feelings, which was true, but the great king of hell could make even a rock feel afraid. The only thing not currently scared out of there mind was you. Out of the corner of your eye you saw a guard take a step back, but this was a mistake as the ground behind him was unstable and began to crumble.
"Hey watch that edge" you called to him.
He jumped at your call but a bigger shout is what finally sent him to his doom.
"Enough!" The great king shouted.
The shout echoed throughout and bounced off the walls before the ground under the demon gave way and he fell screaming into the lava below which would now kill him extremely slowly and painfully.
"Ugh that was one of the useless ones. Waste of space, completely disposable" you heard from the throne as screams echoed around the building bouncing of the walls and striking you hard in the chest.
"How dare you!" You seethed at the king.
"What was that" Satan leaned forward waiting for your response.
"How dare you say that you evil creature, you could have saved him" you growled out at him and grabbed your horns in desperation at the continued screams from the demon below, desperately trying to drown them out.
"I don't know why your so worried about him when you should be more worried about yourself. Also if you haven't realised yet I'm the great evil king so 'evil creature' is actually a very accurate description of me, in fact if the humans knew about us I'm sure that's how they would describe me and how they would probably describe you too" He followed with a laugh.
The screaming from below began to die down as the demon was finally being silenced by the lava, the other guards around you began to laugh along with the king. Clearly all enjoying your humiliation and the demons pain.
"Why? I haven't done anything you just summoned me here" you finally released you magnificent black horns to look up.
"(Y/N) (L/N) you're a powerful demon, but your terrifying presence here is at its end. I here by banish you from hell on the account that you have been planning to murder me" he smirked.
"What!" You shouted and tried to rush forward.
However you couldn't only take a couple of steps before you were grabbed roughly by the horns and then forced down into the stone floor. A large snap was heard and pain followed as one of your horns was snapped in half. You then felt your large black wings being tied with chains, which was also very painful, as it dig into the soft delicate flesh and awkwardly pinned them to your body.
"Yes, your accomplice told me. All I had to do was give him a free pass on everything to do with my murder and also give him the soul that he had been fighting a much stronger demon for." Satan waves his hand and your thought to be friend walked out and stood next to the king
You said nothing and only glared at the demon that looked pretty pleased with himself so Satan continued "he also told me something very interesting, all the demon murders that have been going on. The cause of them was you" and his smirk widened.
"Hey wait-" you were cut off.
A black swirling cloud surrounded you cutting off your vision, the last thing you heard was "goodbye (Y/N)" before you felt your entire body shift as you were sent away from hell forever.
*Flashback End*
That happened thousands of human life times ago. That happened so long ago that you had completely lost count of the days that you had been wondering the earth. During Your banishment, you travelled the earth, eating souls and playing tricks.
Everyone's heard the myth of 'The demon that roamed the lands' and you were proud that you were the one who started it in the first place. Demons on earth weren't a known thing, until you began to create havoc wherever you travelled. You considered it to be like revenge on all those who kicked you from hell and your home, now it was much harder for demons to steal human souls as the humans were far more aware of the demons that were praying on them.
Now however you had settled down into an abandoned area of London that sat next to some of the poorer parts of the city, this kept you hidden and out the way of prying and suspicious eyes. Here you could also stay in your demon form as there was no one to spy on you. Your broken horn had grown back over the years, but it was now a slightly different colour. Still blacker than it ever could be, but the broken half that had regrown was now more of a holographic black.
Your black wings were still chained together as you couldn't break the demon proof metal on your own, this kept them pinned to your body. The metal had dug through your feathers and rubbed the delicate skin making it ugly, raw and painful, the feathers also couldn't grow here due to the chains killing any new feathers instantly. You could still hide your wings though, to fit in with the humans it was just highly uncomfortable for you to do so.
You were completely alone on earth but that was by choice. You knew that any relationship you had with a human would end in pain. Pain that you didn't want in the sad life that you now found yourself in.
But demons didn't have feelings. Right? Wrong. Well... sort of wrong. you were the only demon who was cursed with the horrible weight of feelings. This also meant that you felt the deep set hole inside that only loneliness would be the cause of.
When your sadistic human life ended and you became a demon something went wrong and you were left with what you called a dead soul. The soul was physically there although it wasn't really alive, it was enough that you could pass as human if anything other than a human came sniffing about, however it did attract demons when they were close enough to smell it, as it had a very sweet scent that demons adored.
This gave you another chance to take your revenge on those who hurt you, by hurting or even killing those who tried to steal your sweet smelling soul.
You laid on you back on a fallen marble pillar while the rain pelted down onto your face with closed eyes, you didn't feel the cold as you were a demon, and the rain matched your grim mood. It was going to be another very long and boring day waiting for some poor lonely soul to wander into your home.
*Sebastians POV*
"Good afternoon young master" you spoke as you entered the young masters study.
"Sebastian" Ciel acknowledged
"I have your earl grey tea with a slice of red velvet cake that the queen sent along with this letter" you placed the letter down on Ceils desk as well as then pouring out his tea.
You heard Ceil open the letter and then begin to read it, you placed his tea and the red velvet cake down letting him eat and read the letter at the same time, you then waited to be dismissed to your other household duties.
Ciel finally put the letter down and then turned to you "Sebastian we're going out. I'll explain in the carriage"
"Yes young master" you spoke following him out of his study.
*Time skip*
Now out of his study and in the carriage Ciel was watching outside the window as buildings went by quickly and this was when you decided to speak up "not to be rude sir, but you said you would explain this little outing once we entered the carriage".
"Well first we're heading to the undertaker. A lot of people are going missing on the outskirts of east London and the queen has asked me to find them and the culprit to their disappearances. We'll head to east London once we have the information that the undertaker may have" Ciel didn't look at you.
"Sounds interesting" you smirked.
*Time Skip*
Finally you had reached the undertakers shop and went inside the dark creepy building "Undertaker you in here" you heard Ciel shout.
A loud creepy laugh sounded and one of the coffins slid open to reveal the very person you had been looking for "Do I finally have the pleasure for fitting you for one of my coffins milord".
"No. We're here on the account of people going missing in east London, do you know anything undertaker?" Ciel asked.
"Maybe I do maybe I don't whose to know maybe a little laughter could jog my memory" the undertaker began to laugh as he spoke.
"Sebastian see to it would you" Ciel told you.
"Yes my young lord" you nodded as Ciel turned to leave.
*Time Skip*
It didn't take very long until you had the undertaker in fits of laughter and drool dripping out of his mouth, you heard the door being opened behind you as Ciel walked back in.
"Well, undertaker, heard anything about theses people?" Ciel placed down the pictures he had in front of the undertaker.
"Yes in fact I have. All of these people have been given to me at one point or another but I usually find them in a bag just outside my door and usually is has a note on it with a joke and a small bag of coins in payment. Whoever is dropping them off knows what there doing I'll tell you that." undertaker answers.
"What state are they in when they come to you?" Ciel asked.
"Their bodies are usually intact but they always have a very dead and soulless look on there face" undertaker said.
"Are the pupils in there eyes intact or are they missing?" you asked, cutting off Ciel.
You felt the annoyed stare from him when undertaker spoke "no, they never have any pupils just dead colour. And that's with all of them, that's one of the things they ever have in common when they come to me. Also they are all from a very poor background of living"
"You know something Sebastian" Ciel said.
"Yes but it's not for here" you answered.
"Right tell me in the carriage" Ciel said and then turned to leave but was stopped by the undertaker.
"Tell me young lord have you heard of the myth of the demon so bad they were cursed out of hell itself" the undertaker spoke laughing at the end.
You froze at this, you had certainly heard of this myth or actually truth you had been a demon for quite some time before the trail of said demon, it was a very famous case in hell and Satan used it as an example in every way to keep his subjects in line. In fact the demon that ratted the poor demon out to Satan had been in contest with you for a soul which you were ordered off of by Satan, you quickly put two and two together and realised that he had given up information for the soul you were both pursuing.
You had never met the demon who was cursed away, which meant that even if you were to come in contact with them you'd have no idea as to there real identity, as at the time you had been too angry to even want to turn up and bother with the trial. You were the stronger demon out of those who were fighting for the soul but ultimately you were forced away from it, this was the founding reason why you hated the gods and thought that they were all a bunch of lay abouts, which was true.
"No, what is this myth" Ciel asked.
"Well like I said, there was a demon so bad that the very ruler of hell banished the demon for all eternity. That same demon now wanders the earth stealing souls and causing havoc" the undertaker said.
"Hump. Sebastian, we're leaving" Ciel turned away again and left the building you following behind.
"Take care young lord" was the last thing you heard before you shut the door to his shop.
*Time skip*
"Well Sebastian explain why you asked about the eyes" Ciel prompted.
"When a demon takes a soul usually they have a dead soulless look in there eyes, there pupils shrink so small that they are basically non existent" you explain.
"So do you think it has something to do with that myth the undertaker was babbling about" Ciel asked.
"That is not a myth young lord. The entire story is true, the demon who was banished to earth is the reason you humans know about us higher beings in the first place, and if we are dealing with this demon then as you humans say in a crisis god help us all" you answered.
"I never thought you'd ever be asking the heavens for help" Ciel smirked at you.
You said nothing so Ciel continued "we're now heading to east London, where all the kidnappings have been taking place we'll see what sort of underworld criminal we're dealing with".
"Yes young lord. We shall see" you smirked at Ciel, the carriage still making its way down the cobbled streets.
