I didn't change much except Lucy is now a Celestial fire Demon slayer. So just a slight difference from Natsu power, Celestial fire burns hotter.
"Papa look I made you a rice ball!" A little blonde girl says happily.
"I already told you I'm not hungry, now leave this instance you stupid little girl, I have more important things to do" a once sweet and caring man yells.
Running off before he could hit her like usual the little girl runs to her room. Deciding she could no longer take what her father is doing to her she packs a bag with whatever she can carry, "Open gate of the water bearer, Aquarius!"
"Tch brat, thought I told you to stop summoning from a glass of water" a large looking mermaid says with a tick mark on her face. Raising her urn, she prepares to wash her current master away until she notices the tears and the small pack she has on and her golden keys in her hands.
"What the hell is going on Lucy, where do you think you're going?" the mermaid asks in an unusually soft voice.
Wiping her face, the young girl answers back in a quiet voice "Papa doesn't love me, all he does is hit me and blame me for mama's death, I can't take it anymore so I'm leaving" Lucy says with a fire in her eyes.
Tch about time the girl realizes this guy isn't her father anymore, but where the hell is the girl gonna go. Looking to the little girl she rolls her eyes, "Don't worry Layla I'll make sure the brat doesn't kill herself out there", Aquarius thinks.
Sighing the mermaid looks over everything the mini Layla has "Alright brat, listen up you have about twenty more minutes until your magic is gone, so if you're really gonna do this then we need to pack more, what do you have so far?"
"Uh some clothes, mamas' picture and a few jewels" Lucy says, "oh and my keys" she says happily.
"Well you won't be totally defenseless, but we need more for you to actually get somewhere. So we'll pack some more clothes and a few more essential's that I'll hold in the spirit world. You won't leave until tonight when no one is around, but by then the coast should be clear got it, Capricorn will help you out your window", pausing the mermaid looks away," be careful brat" after shimmering away to preserve what little magic the girl has for tonight.
Smiling the little girl decides to nap before her adventure, unaware of the maids and other servants who had heard of her plans to leave.
"What are we going to do Mrs. Speto" a young servant says, knowing if they let the young heiress go then no doubt heads will roll.
The older maid, smiling says, "Well, first we're going to pack a lunch for Miss Lucy before she goes, then make sure those of us who know about this don't spill, understood".
Looking to the other maids to see of any objections and seeing none the servant just nods their head showing a tiny smile. Walking off to prepare the lunch the maids only wishing good luck to the little girl on her journey.
"Are you ready Miss Lucy?" Capricorn asks.
Putting on her final shoe the little replica of his former master nods her head preparing to climb Capricorns back until she hears soft knocks on her door.
Gasping Lucy looks to the sea goat for what to do only to see a frown on his face. "Capricorn who is that? I thought no one knew about me leaving" Lucy says starting to tear up at the prospect of not being able to leave.
"As did I miss Lucy" the sea goat says confused as to who that may be at the door.
"What do I do, I can't pretend to sleep since I'm already dressed, and I have bags packed- "stopping her rant when she hears a familiar voice, and instead a smile spreading across her face as she goes to open the door before Capricorn can stop her.
"Lucy, may I come in" Miss speto ask.
"Yes, of course" Not realizing how she's dressed until the last minute.
"Hello Lucy, I'm glad I was able to catch you before you left, the maid says catching Lucy and her spirit off guard.
"What, what do you mean? Miss spetto" Lucy says still panicking.
"Oh, don't worry the maids and I won't say anything about your little journey. We overheard you talking to Aquarius about leaving and didn't want you going hungry on the road, so we made you a lunch pack." The maid says smiling, unshed tears in her eyes.
"Miss Speto, I'm gonna really miss you and the others" Lucy says hugging the maid.
Capricorn still on the side smiles at the exchange with his master and her maid with one thought, Layla she really is just like you. I'll be sure to protect her with everything I have.
"Oh, before I forget Bero wanted me to give you this", revealing a gold key, "before you left". It was supposed to be a gift when you finished all your magic lessons, but he felt now was more appropriate"
Gasping at the gift Lucy lets her tears flow, "Thank him for me please." Looking to see who Miss Lucy had just received, Capricorn speaks for the first time the maid has gotten there, "Ahh Taurus is quite strong Miss Lucy, you'll be well protected while on the road now with four gold keys."
"Well off you go now, wouldn't want your father catching you", ticking off do's and don'ts for her journey, "be careful now okay, have fun, oh and don't get hurt" the maid finishes.
Smiling the little girl nods as her spirit lifts her up to go out her room window. Once out they disappear in the night not to be discovered missing until the next day when it is time for the little girl to meet another marriage prospect.
'Where the hell is Lucy?" Jude yells. "This entire deal is riding on her marrying that boy" the rage-filled man yells tossing a vase in the direction of two maids.
Frowning the servants turn around not wanting to be around a man who is willing to marry off an eight-year-old to a teenage boy with a lecherous look in his eye.
"Well! I've asked you a question" his yells all but ignored.
Meanwhile off deep in the forest of Fiore stands a little girl with an eye for adventure. However currently that adventure is fighting off a group of wyverns.
"Taurus to your left!"
"Yes Miss Lucy, I shall protect your adooorable body" the newly contracted spirit yells.
As the bull continues to fight Lucy stands on the sideline directing the spirit so he doesn't get hurt. I may not be able to fight but I can support Taurus from the sidelines, Lucy thinks as she directs Taurus to duck as another Wyvern jumps at him.
"Luucy I'm Sorry but I have to go back you're too low on magic!" The bull yells regretfully.
Falling to the floor Lucy realizes Taurus is correct. While he was fighting her magic container was draining immensely, and now she can barely move. And while Taurus did take out most Wyverns there's still two left.
Now directly in front of her stand two frightfully tall monsters who look mad she just took out all their friends.
I can't believe it, barely a day out here and I'm already going to die, Lucy thinks crying. I just wanted to get away from Papa.
"CELESTIAL SECRET ARTS: FIRE DEMON WRAAAATH" ducking when she feels an immense heat coming from her back Lucy rolls to the side as she sees the two wyverns disappear into ash.
"Whoa who was that, no what was that?" Lucy asks.
"That was my Demon Wrath, as insinuated in the name child" a deep voice says in front of Lucy.
Opening her eyes Lucy sees something she's only ever seen in stories, "whoa You're a-
"Demon yes, and you're quite strong for a munchkin" the flamed being says scrutinizing the little girl in front of him.
"Really you think so, I mean I almost got killed right now." Lucy says ashamed.
Rolling his eyes, the fire demon plops on his stomach getting to the girls' height, "yes but that was after holding open that golden keys' gate for about twenty minutes and taking down about fifteen of those weird monkey monsters". Looking up and down at the little girl he asks "What is your name? Blonde one".
Mouth agape Lucy slowly smiles, never complimented by anyone outside her house when seeing her magic.
"My names Lucy Heartfilia and Thank you, mama taught me her celestial magic when I was little, so I would be able to inherit her keys", lifting up her key ring to show her four gold keys and two silver, "What's your name?"
"I am Lucifer the Celestial fire Demon" the mythical creature answers.
"OOOH, are there any others like you?" For a demon he sure is nice, in all the stories I've read they're portrayed as evil but this one seems nice, Mama was right never judge a book by a cover
"No, I am the only of my kind, but there are type of slayers. However, I would say I am the strongest of all slayers".
"Hmm that's pretty cool. I've never heard of Demon slaying magic before! Hey, can I call you Luce? Lucifer is kind of intimidating" The energetic blonde says.
"Tsk, too many questions for such a small person, but to answer your question... yes you may call me Luce"
"YAY, my first friend!" Lucy says jumping up and down. "Wait a sec, you said Celestial Fire Demon?,"
"Yes and?" the Demon says annoyed".
"Well, which is it?,"
"are you a celestial being or a Demon?"
"I am a CE-LE-STI-AL FI-RE DE-MON" Luce says dragging out each word sarcastically.
"How? I've never heard of there being such a thing" Lucy says granting more questions.
"And yet here I am." The fire beast says looking down at the blonde grinning.
Pouting the blonde looks away, muttering about rude demons and defying logic.
She's quite strong with having four gold keys- and not at all afraid of me, hmm yes, she will do just fine, the Celestial fire demon says to himself. She is also adorable, which will trick many foes into underestimating her power, the demon coos.
Looking up and down at the little girl in front of him the demon gives what Lucy thinks is a smile before offering the chance of a lifetime.
"That's it, it is decided tiny one" the fire demon says.
"What is" Lucy says smiling.
"Lucy Heartfilia I will teach you Demon Slayer magic!"
"Whaaat?"
8 months later
"Lucy, how do you expect to be a top-notch Demon slayer if you can't even make a Demons Wrath yet?" Luce says lazily.
"I'm trying!" the little blond says.
"Hmm maybe she needs an incentive, no, something else" looking to where the little girls most prized possession was the demon rolls over saying "Oh Luuucy, if you don't produce even the smallest Celestial flame today then I'm going to melt your mothers gate keys, capiche?" the demon says not at all serious.
Gasping at the threat Lucy fills with dread, "You wouldn't".
"I'm a demon so I would, in five"
"Lucifer, don't you dare" glaring at the towering demon Lucy steps forward, unnoticed by the girl, her surroundings begin to heat up at an immeasurable temperature.
"Four and I shall dare" there it is, Luce thinks as he feels the heat rise with a golden hue begin to shine around the girl.
Slowly Lucy fills with a feeling she hasn't felt since she's started training with Luce 9 months ago. A golden light has begun to surround her, as heat fills her entire body when anger towards her parental figure takes over.
"Two, I don't see you trying Lucy" Luce sings, intentionally skipping a number to further along the girl who he can see is about to finally make progress.
"I said no you won't Luce and I meant it" The little girl threatens at the final step of her lesson.
"Well since I have your keys, you can't really do anything now can you," lighting his hand up Lucifer smiles when he sees the oncoming attack.
"Oh yes I can! CELESTIAL FIRE DEMONS WRAAAATTH" Lucy yells at the last moment, surprising the demon and herself at how strong her fire is.
"Amazing, for a mere human her fire is almost as strong as mine, you really will be the strongest slayer amongst all mages" the demon smiles.
"HAHAHAHA, THAT'S RIGHT HEARTFILIA RELEASE YOUR WRATH!" the celestial demon screams.
Swirling around the him unaffected was scorching flames, blinding wildlife miles away. Yes, she will progress much faster from now on.
"You damn demon, GIVE ME BACK THOSE KEYS!" the demon slayer yells.
Laughing the Celestial fire demon walks up to the little blonde tossing her prized possession to her, "You know they were never in any danger, right? I informed Capricorn of the plan, so he knew to take them away at the last second"
"He's right Miss Lucy, I apologize for the deception, but he told us of how this might help you progress" an apologetic Capricorn says.
"well I guess if you were never in danger then it's okay, but you're still a jackass", Lucy mumbles.
"But look now we can go onto the next lesson: Celestial Demons hellfire Fist and Fire Demons Kick"
Looking away Lucy frowns until she realizes that Lucifer is right, that although his methods were a bit unorthodox, they can now move on and start working on more moves faster.
"You know I'm right, don't you "The demon says in the voice Lucy has come to know as his smug voice.
"Yeah, yeah, let's just get on with the lessons" Lucy pouts rolling her eyes.
Smiling Capricorn hands his keys to his master before closing his gate, good luck Miss Lucy.
