A/N: Yep! My first update of the year and new story! Though it's not a surprise to those who read my Word of God Blog on Tumblr... This story is an AU for Fairy Tail (as well as Sailor Moon), not only is there a For Want of a Nail (with more changes later on), Edolas doesn't play a role at all. However Exceed still exist but they go by a different name and have some unique traits and were combined with Mau from Sailor Moon sort of... Also for the Sailor Moon elements it will have elements from both manga/Crystal and the original anime. I hope you enjoy!

Also I won't say who the other three Guardians are... (Sailor V is easy to figure out once you read it...).

Disclaimer: I don't own Fairy Tail or Sailor Moon... if I did then I would find a way to end the complaints about Crystal... Permanently... Mwahahahahaha!

Happy: But she does own any OC that may appear...

Fairy Moon

By Emma Iveli

Chapter 1: Sailor Moon

The Taker Over Siblings were one of the most well known teams of Fairy Tail. The Oldest Mirajane had the magic Take Over: Satan Soul, the middle Elfman had the magic Take Over: Beast Soul and the youngest Lisanna had the magic Take Over: Animal Soul.

Mirajane was most the powerful and was considered an S Class Mage of Fairy Tail, which was why she was able to take her siblings with her.

It was a mistake, they had to fight a monster called The Beast, Elfman tired to take it over but it was too much to handle.

"Mira!" called out Lisanna as she was in her bird form flying to her older sister, she changed back to human, "What's going on?"

"It's Elfman…" cried Mirajane, "He tried to take over The Beast… but…"

Lisanna looked at the Beast before her. She knew what she had to do.

"Elfman!" called out Lisanna, "It's me! Lisanna."

She said these words, she unconsciously called upon a magic she didn't know she had, she was surrounded by a golden glow.

"Please big brother! Stop this! Let's go home together." Said Lisanna.

The Beast that was Elfman was about to strike, however something else happened.

The glow around Lisanna intensified and a yellow crescent moon appeared on her forehead.

The glow blinded the beast… until certain words came out.

"Lisanna…?"

However when the glow died down Lisanna suddenly collapsed.

"Lisanna!" called out Mirajane.

Both she and Elfman ran over to their sister, thankfully she was still breathing, it took about a minute but the yellow cresset moon eventfully faded.

"What happened?" asked Elfman still as the beast.

"I don't know…" said Mirajane.

She looked at her brother, "You might want to switch back…"

"Yeah…" sighed Elfman.

Thankfully Lisanna only had minor Magical Exhaustion. When they had gotten back to Fairy Tail, they had discussed with what happened with their guild's master Makarov.

"So you don't know what you did?" asked Makarov.

"No." answered Lisanna.

Makarov began to think.

"Do you know what happened?" asked Elfman.

"No idea…" answered Makarov.

"Seriously!" yelled Mirajane.

"I do have a theory however…" said Makarov, "That Lisanna has an magic hidden deep within her?"

"What kind of magic?" asked Lisanna.

"I don't know… but something tells me it will be important in the future." Said Makarov.

Lisanna nodded.

Little did any of them knew was that this would be the most important moments of Lisanna's life… though she didn't' know yet.

One Year Later…

One morning Lisanna was walking to the Guild Hall, she has promised her best friend Natsu that she would spend the day with him as both of them had been busy the past month with missions.

As she passerby a new jewelry store that had opened she accidently stopped on something soft. She went to see what it was, it was a Moon Cat.

Moon Cats were extremely rare animals, not only could they talk but they also had magic that allowed them fly, those truly skilled or powerful can obtain a human form but those Moon Cats are extremely rare.

She looked around, this one was black and it had a strange yellow bald spot on its forehead.

"Hey?" are you okay?" asked Lisanna.

The Moon Cat looked at her, not saying anything.

"I guess I should take you to the guild if you're not talking." Said Lisanna.

"Wait you know I can talk?" asked the moon cat.

That was when she noticed the Fairy Tail Mark on Lisanna's shoulder, "You're a mage of Fairy Tail… I did hear that was one with a moon cat."

Out of the many guilds that dot the landscape, only a few of them had Moon Cats in their membership, Fairy Tail was among them.

"Oh you mean Happy." Said Lisanna.

The Moon Cat nodded, "I want to join your guild. "

"You do?" asked Lisanna.

"I do…" responded the moon cat.

"Okay…" said Lisanna who didn't know why but she was a little unsure about it.

The Moon Cat followed Lisanna to the guildhall.

"Morning everyone!" called out Lisanna.

Those were already there waved.

"Hey! Lisanna!" called out Natsu.

"Lisanna"! called out Happy, the guild's moon cat.

That was when they noticed the moon cat behind Liana.

"Oh this is…" said Lisanna.

"Luna." Said the moon cat.

"She wants to join the guild." Said Lisanna.

"Really another moon cat!" cheered Happy, "I only know mom and Lucky!"

Lucky was Happy's father… it's best not to get into their relationship now…

Thankfully Makarov was at the bar.

"So you want to be a Fairy Tail mage?" asked Makarov.

Luna nodded.

Makarov took out the Guild Mark stamp and Luna and he began to discus where to place the mark and what color.

"So what do you want to do today?" asked Lisanna.

"Well…" said Natsu.

That was when Mirajane stormed in.

"Where's Erza!" she yelled.

"Um… Erza's on a mission right now…" said one to waitresses.

"Why that…" muttered Mirajane.

"Mira… what's wrong…" said Lisanna trying to reassure her sister.

Mirajane took out the latest issue of Sorcerer's Weekly. On the cover was a girl with blonde hair, some of her hair was tied by a red ribbon in a side ponytail while the rest of her hair was worn down, but the most notable thing was that she was wearing a red mask and wore a strange outfit based around a sailor suit.

"They bumped me for Sailor V!" yelled Mirajane.

"Sailor V?" asked Natsu.

"Oh you haven't heard, Sailor V is a mage that's been helping fight crime all over the country." Said Lisanna, "It's said that very few people know who she actually is..."

"Aye!" said Happy, "She's very popular right now…"

"Even you heard of her…" muttered Natsu.

"You're just not in tune with what's popular." Shrugged Happy.

"If I ever meet her I will give her a piece of my mind!" yelled Mirajane.

"Do you want to do something no where near the gold hall?" asked Natsu with a sweat drop.

"That's sounds like a good idea." agreed Lisanna.

As they left, Luna (now with a yellow guild mark on her back) watched, she looked at the rest of the guildhall.

"I'll talk to her later." Thought Luna, "But I can sense the others might be here… I'll have to look around see if they're here…"

As they went to the fishing hole, they walked passed the new jewelry store.

Natsu stopped.

"Is something wrong Natsu?" asked Lisanna.

"No… not really." Said Natsu.

They continued on they're to the usual fishing hole, completely unaware what was going on in that new Jewelry store.

Lisanna, Natsu and Happy had a fun day, they did go fishing but afterward, they went to their favorite spot and watched the sun set.

Of course during that time Happy had to say this "You are in looove."

"Stop saying that!" yelled Natsu.

"It's not like that!" yelled Lisanna.

Other than bit it was a fun day.

As Lisanna walked home she couldn't help but to think "I have to find more time."

That was when she heard a scream.

Instinctively she ran over to the location of the scream. It was the new jewelry store, she looked through the window and saw that it was littered with unconscious bodies, while she saw a horrific looking creature choke a young girl.

Lisanna was about to go in when she someone shout.

"Lisanna, wait!"

She turned to see it was Luna.

"I know you're a wizard but what's in there is something that most wizard's can't possibly handle…" said Luna

"How do you know."

Luna sighed, "What I am about to tell you is unbelievable, but there is a great evil that wants to take over the world. It is my duty to fine the lost Princess and the Sailor Guardians… you are one of the Sailor Guardians, you are Sailor Moon!"

"Sailor Moon?" asked Lisanna.

Suddenly she remembered what happened on the mission, the magic she had but hadn't been able to use since then.

"I under stand if you don't believe me…" said Luna.

"No I believe you…" said Lisanna.

"Wait?" asked Luna, "You do."

Lisanna nodded.

"I had this whole speech in mind… then again I wasn't expecting the person to be a guild mage…" sighed Luna.

Luna handed her a golden brooch, it had a crescent moon on it and four gems surrounded it, one blue, one red, one green and one orange.

"In order to tap into this magic hold this and say Moon Prism Power! Make-up!" said Luna.

Lisanna was a little unsure, but did so, "Moon Prism Power! Make-up!"

There was a flash of light at her clothes turned to ribbons with took the form of a leotard, along with a sailor collar, a large ribbon in the front and one on her lower back, knee high red boots appeared on her legs and a tiara appear on her forehead, but what was most not table was a rather short miniskirt attaching itself to the leotard.

Lisanna looked at her reflection in the window.

"In this form you are called Sailor Moon."

"Does the skirt need to be this short?" she asked, "And do I have to dress like this? What if someone sees me like this…"

That was when she noticed that her guild mark was gone.

"Don't worry…" said Luna, "There is a disuse field, even if you ran into someone you knew they wouldn't recognize you, don't worry your guild mark is still there, it's just hidden…"

There was another scream coming from the store.

"Sailor Moon you have to go in there." Said Luna.

Sailor Moon nodded.

Sailor Moon entered the jewelry store.

"Hold it right there!" shouted Lisana.

The horrific monster let go of the girl she was choking.

"How are you?" asked the monster.

That was when she was suddenly compelled to perform a speech with certain movements.

"I am the pretty guardian of love and justice Sailor Moon! In the name of the moon I will punish you!" called out Sailor Moon.

There was an awkward silence.

"What was that!" yelled Sailor Moon blushing bright red.

"I don't know…" said Luna with a sweat drop.

"Sailor Moon I never heard of you…" said the monster.

"I'm new at this…" admitted Sailor Moon.

"Well you're about to die… now those who have given their energy to our great ruler, rise!" ordered the monster.

All of the unconscious women around them got up, all of them with blank expressions.

All of them lunged at Sailor Moon who managed to dodge.

"Sailor Moon you have to attack the monster!" said Luna.

"How? I don't know how to use this magic remember." Said Sailor Moon.

Before Luna could tell her anything the monster reached out to attack Sailor Moon, when suddenly a fire ball hot the monster.

They turned to the source it was a man covered head to toe in red armor that vaguely resembled a dragon.

"And who are you?" asked the monster.

"I am Dragon Knight." Said the man.

"Do you know who he is?" asked Sailor Moon.

Luna shook her head no.

Then Luna realized something.

"Sailor Moon now! Grab your tiara and shout Moon Tiara Action!" said Luna.

Sailor Moon did so, when she did the tiara turned into a glowing disc

Moon Tiara Action!" called out Sailor Moon.

The glowing disc hit the monster turning it to dust.

Somewhere else a man scowled.

"Morgana failed…" muttered the man.

Sailor breathed a sigh of relief.

"Sailor Moon." Said Dragon Knight, "I know that whatever you will face will test you… have faith in yourself."

With that Dragon Knight jumped out of a window and disappeared.

That was when people regained consciousness.

Outside Luna and Sailor Moon heard voices.

"IT's happening in here!" shouted a voice.

"All right show me where this monster is!" shouted a voice.

"It's Mira…" said Sailor Moon.

That was when a bystander who must have escaped showed up with Mirajane and Elfman.

"Okay… who are you!" demanded Mirajane pointing at Sailor Moon.

"Um… well…" said Sailor Moon, "I'm Sailor Moon… and I stopped the monster."

"I see…" said Mirajane.

Sailor Moon inwardly breathed a sigh of relief realizing that the disguise field was working.

"By the way dodo you know Sailor V?" asked Mirajane.

Sailor Moon sweat dropped, "No… I just started today… and…"

She saw Luna motioning at her to follow.

"I really have to go!" said Sailor Moon running out of the store.

"Should I say why…" said the bystander.

"Best if you don't…" said Elfman.

Sailor Moon and Luna went to an ally.

"How do I change back?" asked Sailor Moon.

"Just focus." Explained Luna.

Sailor Moon did and went back to being Lisanna.

"Someone must have went to guild." Said Lisanna.

Luna nodded.

""We have to tell someone…" she sighed, "I'd rather not have to fight my sister."

"I was thinking the same thing…" said Luna, "I already have someone in mind…"

"Who?" asked Lisanna.

The next day Lisanna and Luna talked to Makarov in his office.

"So that was you…" sighed Makarov, "I had heard about that…"

Lisanna nodded.

"Can you show me this Sailor Moon form?" asked Makarov.

"Sure." Said Lisanna, "Moon Prism Power! Make-up!"

She once again transformed, of course when it was done Makarov couldn't help but to grin a little and blush.

"That is such an amazing transformation… and the outfit is amazing too." He said.

"Seriously?" asked Luna while Sailor Moon sighed.

Makarov managed to regain his composure, "I did notice that you don't have your guild mark."

"The magic not only prevents anyone from reckoning her but also hides any and all guild marks…" said Luna.

"Is it possible to apply a second one?" asked Makarov, "One that only appears in this form?"

"I don't know we can always test it out." Said Luna.

"Why?" asked Sailor Moon.

Makarov sighed, "Well the magic council has been comparing about Sailor V not being a member of any guild…" he explained, "It's been a sore topic in the last few league meetings…"

"Really?" both of them asked with sweat drops.

"Yeah…" sighed Makarov, "However if Sailor Moon is official member."

"Then the magic council won't think of her as nuisance…" said Luna.

Makarov nodded.

Sailor Moon sighed, knowing that he already had enough from the magic council what with most the guild causing problems.

"I'll see what happens…" said Sailor Moon.

"So where do you want your Guild Mark?" asked Makarov.

Sailor Moon began to think.

"How about on my thigh in white." Said Sailor Moon.

Makarov nodded knowing why that spot. Once she transformed back the new mark was gone and her old one was back.

"Aren't you going to transform again to check?" asked Makarov.

"I'll do it later." Sighed Lisanna.

"Now…" said Luna, "You new duty is dangerous, the less people know that your Sailor Moon the better… this enemy will go after more people and it will up to you to find them and fight them…"

Lisanna nodded.

"Don't worry Lisanna, I'm sure you can handle it." Said Makarov.

"I'm not worried." Said Lisanna.

Lisanna left the office yet Luna remained.

"There's something you wanted to ask me, isn't there?" asked Makarov.

"There are more Sailor Guardians and I belie their all members." Said Luna.

"You want a list of the mages, don't you." said Makarov.

Luna nodded, after all the sooner she began her search the better.

However this was only the begging of this story, and who knows what will happen in the future.

Next Time: Lisanna must figure out how to break it to Mirajane and Elfman that she can't work with them any more. Meanwhile Luna discovers an old friend is in the guild. Who is it? Find out next time!
