Hiya everyone and happy new year! This is going to be my first Black Butler fanfiction story cause I recently got into the series and I loved it. I'm going to write this story based on a Black Butler RP I'm in, it will be about Luna Eclipse a 10 year old orphaned girl who lost her parents, was kidnapped, and experimented on giving her the power to turn into a small purple dragon or a silver wolf and has a scar in the shape of the crescent moon with three stars which glows blue on the full moon. How will she escape from her captors and where will she go once she's free? You will just have to read to find out.

I'm still just a beginner so go easy on me in the reviews. Also I had to redo this chapter completely do to several parts that I messed up by accident due to writing it at 1:30 am so please forgive me.

Disclaimer: I do not own the characters from Black Butler nor do I make any money from writing this story. I only wrote this story for fun. I do however own Luna Eclipse.

Warning: There will be spankings in this story so if you don't like it then don't read. In this chapter there will be a minor scene with blood or someone being killed. You have been warned.

Chapter 1

It was a partly cloudy day with a chilly breeze, the sun peeking through the clouds on occasion to give some warmth on the ground below for a short while until eventually being covered by the clouds again. There was a big building in an abandoned forest on the outskirts of London with hundreds of guards surrounding the building holding guns while on look out to keep out trespassers. This place was known as the Lab House due to illegal experiments on kids and animals. A man in a white lab coat, blonde hair, blue eyes, and black shoes was walking towards a room with a sign that says "hybrid room" and walked inside. The room was dark so he turned on the lights so he can see, there was a big cage in the back of the room with what looked like a scared little girl. The girl had brown hair with black highlights, brown eyes, wore a pink shirt, a purple skirt, and had blue and silver shoes. This man walked towards the cage, grabbed a chair, put it in front of the cage, and sat down with a smirk.

"Ah, good morning little one, how are you feeling today?" The man in white said in an intimidating way making the girl whimper.

"I have a name Jake and it's Luna Eclipse. As for how I feel, that's obvious, I feel scared and want out of this stupid cage and away from you monsters." Luna said with a glare trying to hide her fear on her face.

Jake's smirk widened and wagged his finger at her. "My what strong words for such a little girl, but nothing you do will help because you are stuck here and will never leave." Jake said menacingly shaking the bars of the cage for effect.

Luna's glare darkened as she then turned into a silver wolf and scratched at the man's hands effectively hurting him to which he withdrew his now bloody hand. Jake stepped back a few steps away from the cage in case she tried anything else.

"Let me out of here you jerk! I will kill you for what you did to my parents and to me!" Luna yelled out at the man who merely laughed evilly.

"Ha! You should consider yourself lucky that I decided to spare your life you little brat! Besides you have the scar that will always bind you to me and this place. Even if you manage to escape you will always be my little pet no matter where you go." Jake said in a menacing voice causing Luna to whimper and lower her ears.

"I don't care if this stupid scar does bind me I will fight back for my freedom!" Luna shouted determined to escape from her prison.

With that said she then turned into a small purple dragon, took a deep breath, and blew very hot flames at her cage which melted the bars instantly. Jake was very shocked that his pet was able to free herself from her cage but quickly recovered from the shock and ran out of the room as fast as he could. Luna roared very loudly causing the room and the entire building to shake and flew after Jake, catching him by the back of his lab coat, and glared at him growling darkly while baring her fangs at him.

"O-ok please p-put me down and no one will get hurt." Jake said nervously hoping she won't go through with her threat.

"You will pay for what you did to my parents and to me with your life! Now die!" Luna roared in his face.

A few seconds later she threw him hard against the floor, pinned him to the ground, and started to tear him to pieces with her claws and teeth splashing blood on the walls and floor. Once she was done all that remained of Jake was his torn up lab coat, shoes, and limbs in a pool of blood. Luna cleaned herself from the blood that was on her claws and body then blew fire at a wall burning a hole into it and flew out into the chilly morning as fast and far as she could go not caring where she went as long as she was far away from the Lab House.

* Meanwhile at the Phantomhive mansion *

"Ok Sebastian, what is on today's schedule?" Ciel Phantomhive said in a bored tone.

"Today you have some papers to finish for the Queen, paperwork for your company, and a new case the Queen wants you to solve is to rescue this girl named Luna Eclipse from the Lab House which is a place that deals with illegal experimentation on young kids." Sebastian said reading a list of things for Ciel to do.

"Hmph...just boring paperwork as always and what's this about a Lab House? I've never heard of a place like that before." The young earl said still bored but with slight curiosity.

"The Lab House is a building that has been taking young kids and animals and experimenting on them illegally. It's located on the outskirts of London so that's probably why you've never heard of it my lord." Sebastian replied to his master.

"Oh really? That is just sickening to hear that kids and animals are being experimented on like some lab rats. Sebastian this is an order! You are to-" But Ciel was cut off at the sight of a small purple dragon that flew across his window. "go check out what I just saw in the yard and bring it to me alive." Ciel said still shocked at what he saw.

"Yes my lord." Sebastian said as he bowed slightly with his right hand on his chest.

The demon butler then left and went outside to find the small purple dragon. It didn't take long for him to find what he was told to look for as the poor thing was trying to hide from the demon hound, Pluto, who was barking at her. Sebastian quickly shooed Pluto away by throwing a dog treat into the distance, once the demon hound was gone the dragon landed on the ground clearly very tired from flying for a long time. The demon butler stood in shock as he watched as the dragon turned into a young girl who passed out from exhaustion, he carefully walked to her and gently picked her up then walked back into the mansion and back into the room where Ciel was waiting.

"What happened to the dragon I saw? And who is that?" Ciel asked his demon butler.

"You're looking at her, apparently this little girl can turn into a small purple dragon because when she landed on the ground she passed out and turned into the girl you see here in my arms. I unfortunately don't know who she is so I suggest that we wait until she regains consciousness." Sebastian explained to his master.

"Well put her on the couch for now, but once she wakes up I will ask her the questions I need answered." Ciel replied to Sebastion.

It was about several hours of waiting until the girl finally woke up, she yawned and stretched then looked around wondering where she was slightly nervous.

"Ah, good you're awake. Would you please care to explain who you are, where you came from, and why you were a dragon?" Ciel asked her who jumped slightly.

"Um...my name is Luna Eclipse sir, I'm a 10 year old orphan cause my parents were killed by these bad men who kidnapped me and took me to the Lab House to experiment on me giving me the power to turn into a small purple dragon and a silver wolf. They gave me this scar that is in the shape of a crescent moon on my back as their way of marking me as their pet. I was in that awful place for several months in a cage until I managed to finally be able to escape and now I'm here. So who are you two?" Luna explained her story to the young earl and the demon butler.

Both Ciel and Sebastian stared at her for a few moments in shock until Ciel cleared his throat. "I'm Ciel Phantomhive the earl of this mansion and this is my butler Sebastian Michaelis, but at least you're safe now so you don't have to worry about going back to that God forsaken place. Unfortunately you cannot stay here because I am too busy to deal with the needs of an orphaned girl with powers, so I will have my butler call an orphanage to collect you." Ciel told the girl who started to tear up.

"NO! Please don't send me to an orphanage! I don't trust others anymore not after what I went through and besides who would want me with my powers and my scar? So please Ciel let me stay! I will do whatever it takes to earn my keep here by doing chores, helping out with whatever it is you need, but please don't send me away!" Luna cried out pleading to him with tears in her eyes.

"Master, may I have a word with you for a moment?" Sebastian asked his master who was about to say something.

"Fine, whatever Sebastian, just make it quick." Ciel replied in an annoyed voice.

Sebastian lead the young earl to an empty room so Luna won't be able to hear them and closed the door just in case.

"I suggest that we keep her for a couple of reasons, one is because of her powers which may prove useful for you, for example she can help Pluto out with guarding the mansion in either her wolf form or dragon form while you and I have to leave for a certain amount of time. Two, she's only 10 and has been through a lot in the last few months so I would advise that you reconsider sending her to an orphanage, sir." Sebastian explained to his master.

"Hmph...whatever but you are to be her guardian, Sebastian, and that is an order. You are to make sure she does her chores, keep her happy and safe, treat her with respect, try to be fatherly towards her since she needs an adult figure right now, protect her from any harm or danger, and punish her when she is bad. If she behaves and do her chores properly then I might consider getting adoption papers for you to sign." Ciel ordered his demon butler then smirked picturing the demon as a father.

"Yes my lord." Sebastian said kneeling on one knee with his head bowed and his right hand on his chest.

The two then went back to the room they left Luna in and saw that she was hugging a pillow silently crying huddled in a ball on the couch. Sebastian gave Ciel a look that would make anyone shiver but Ciel just rolled his eyes and sighed then went to sit on his fancy chair behind his desk while Sebastian went over to comfort the crying girl by sitting next to her and rubbing soothing circles on her back while she got it out of her system. Once she was calm enough he told her what they decided and she immediately became happy and hugged him tightly.

"Yay! Thank you so much Ciel for letting me stay and having Sebastian be my guardian...now that I have a good look at you though you remind me of my daddy, Sebastian." Luna said poking his shoulder giggling.

"I do, do I? Well then since I am your guardian you can call me whatever you want, but I do have some rules for you to follow and if you break any of them you will be punished, do you understand me?" Sebastian told her with a firm voice.

"Well that's easy, I'm going to call you dad or daddy!" She smiled brightly but then her smile quickly turned into a frown at the mention of punishments and pouted. "Aww ok, I'm listening." Luna replied and got comfortable on his lap still hugging the pillow.

"Alright then, you are to do a set amount of chores and if you refuse or don't do it properly then you will be punished. No fighting, arguing, lying, attitude, whining, flying in the house in your dragon form, running, being rude, name calling, digging holes in the backyard, or breaking anything. You are to stay out of locked doors, ask for my permission or my master's permission to go outside or to town, don't track in dirt, and don't cause trouble or mischief." Sebastian paused for a moment to let everything he said so far sink in and then continued. "If you break any of these rules then I will punish you by either a spanking, grounding, timeout, toys taken away, privileges taken away, or no dessert." The demon butler finished explaining the rules and punishments to his new ward.

"Yeah, I understand and I will do my best to behave so I won't have to be punished which will be hard for me since I'm 10." Luna said poking the pillow she was hugging.

"Oh and one more thing, if you do behave for me and my master and do your chores properly then the young lord will consider getting adoption papers for you to be my adoptive daughter. You can still call me dad or daddy if you wish since that seems to make you happy. So, how does that sound miss Luna? Do you think you can handle this?" Sebastian said with a kind smile.

"That's awesome! I'm pretty well behaved when I'm focused on my chores so of course I will be able to handle this. I can't wait until you become my official adoptive daddy! This is so exciting!" Luna said excitedly and started to bounce up and down happily causing Sebastian to chuckle lightly.

"Alright well I've got to go and prepare lunch before Baldroy decides to use his flamethrower or dynamite again, so Luna please come with me you can help me with preparing the food." Sebastian told the young girl who nodded and followed after him to the kitchen.

Once the two were gone Ciel let his head fall on the desk and took a deep breathe then stared into space deep in thought. 'I hope this girl doesn't ruin anything important because if she does then she will be kicked out immediately. Broken vases or statues I can handle since Finny pretty much breaks anything he touches, Mey-Rin would almost always break many plates and dishes, and Baldroy seems to always blow up a hole in the wall in the kitchen...but not my documents or papers that is off limits and where I draw the line.' Ciel thought to himself.

* Meanwhile in the kitchen *

"What are you talking about, Sebastian? I can cook up some lunch for the master just fine with my trusty flamethrower!" Baldroy said defiantly and brought out his flamethrower.

"Luna! Watch out!" Sebastian called out to the young girl who was closest to the stubborn chef.

Just seconds before the explosion the demon butler quickly picked up Luna and ducked behind a far away table protecting her from the blast. Once the smoke cleared Sebastian let go of Luna and glared at Baldroy who had a sheepish grin, poofy hair, and covered in ash.

"Oops, my bad! I can't seem to stop using that thing." Baldroy said scratching the back of his head with his hand.

"You best be on your way now Baldroy and please do try to stop using that flamethrower." The demon butler told the chef who simply grunted and then left the kitchen to do something else. "Alright then Luna, please wait for me at the door while I clean up his mess." Sebastian told her and she obeyed.

Several minutes later and she was called back in only to be shocked by how clean and spotless the kitchen looked as if an explosion never even happened here.

"Wow! How did you do that dad? This kitchen looks amazing!" Luna said looking around clearly amazed.

"I'm simply one hell of a butler, miss Luna." Sebastian said smirking with his eyes glowing bright red.

An hour later lunch was made, Sebastian had Mey-Rin bring in the drinks, Finny to bring in the food, and Baldroy to go and get Ciel for lunch. Ciel sat at his usual chair while Luna sat on the right side of him giggling and in a good mood.

"For today's lunch is something that miss Luna suggested to make, which is a chicken sandwich with tomatoes, mayonnaise, and lettace, a fruit parfait with apples, bananas, grapes, and vanilla yogurt, chocolate milk, and then for dessert is a small chocolate cake." Sebastian explained the menu to the young earl.

Lunch went by quietly and uneventful, Ciel enjoyed the meal and thanked Luna for the suggestion then excused himself to go back to his study and continue his paperwork. Luna asked for seconds due to the fact that this was her first real meal in months so Sebastian served her seconds and she ate it quickly managing to not get herself dirty. Once she was satisfied she helped clean up and put the dishes away surprising Sebastian by cleaning all of the dishes by herself in hopes of getting closer to the possibility of Sebastian adopting her. It took her about an hour to clean all the dishes with Sebastian keeping an eye on her just in case. When she was done she went to her room and took a nap until dinner was ready. The demon butler came in to check on her and to tell her that it was time for dinner but stopped at the sight of how Luna was sound asleep and looking as though nothing could wake her up. Deciding to leave her food on her nightstand in case she wakes up later in the night so she can eat, Sebastian quietly left her room and walked back downstairs smiling softly. Even though Luna was in a deep sleep she could sense the demon butler's presence and smiled in her sleep feeling happy knowing that she found a home and a new family.

'I think I will surprise miss Luna with some gifts so when she wakes up she can have new clothes and toys. Let's see if I go to the stores when they open then I will have enough time to get back here before she wakes up.' Sebastian thought to himself after he put Ciel to bed and wandered the dark halls of the mansion in the middle of the night.

Yay! Chapter 1 is officially done so I hope you all enjoy this new version and please review it makes me happy. I will post chapter 2 as soon as I can so please don't get upset if I delay because I do get busy or get hit with writer's block.
