Aqua Fire Queen: sorry, your private messaging is apparently disabled. No, Lucy won't become the strongest in the guild, not by long shot. She is getting stronger physically and magically, but she's not a powerhouse so much as she's learned how to use what she has more effectively. As for villains that might join Fairy Tail…hm. Villains from the crossover series, maybe, but I haven't thought about it for actual Fairy Tail characters. I suppose Flare is a possibility, but she seemed happy to be back in her home village. Or I can briefly mention the Key of the Starry Skies arc and have Mary Hughes, at least, join the guild. I don't know.

Guest who didn't leave a name: yes, really. Hiccup, Toothless, and Jack were in the original story, too.

Enjoy!

Lucy stared in utter bemusement at her newest spirits, Lepus and Lupus, the Hare and the Wolf.

It had been odd enough that she had been forced to buy the two silver keys together (not that she wouldn't have, but she had to), because there was a blue string tying the two keys together that apparently no one had ever been able to remove.

Fairy Tail was currently holding a sort of arts festival, in another attempt to bring in a profit as well as to shamelessly promote their guild in the hopes of drawing in more members.

"Takeshi!" Honey, the Celestial Spirit for the Hare constellation called with a giggle. "This cake is really good!"

"Ah." Mori (as only Honey was allowed to call him by his first name) agreed with a nod, expressionless.

A group of girls from Blue Pegasus swooned at the sight.

Sherry and Chelia Blendy, Sherry's seven year old cousin, had stars in their eyes as they looked at the example of familial love.

Mori was extremely tall, at least compared to Honey. He had black hair and almost black eyes. The only one who managed to get him to talk was Honey, who Mori protected with every fiber of his being, though the Hare didn't need it. He was very hard to read, and Lucy was almost tempted to play poker with him.

Honey was rather short at 4'11, though he was supposed to be eighteen years old physically. He had honey- blonde hair, large brown eyes, and an infectious grin. He was sweet, charming, and adorable. He also carried a pink rabbit plush he called 'Usa-chan' with him everywhere he went.

You wouldn't know it by looking at him, but he was also a very dangerous fighter.

For one thing, Honey was very manipulative when he wanted to be, using his 'kawaii' personality to charm people into giving him sweets, especially cake. He had mastered the puppy-dog look (complete with tears) a very long time ago.

Honey and Mori didn't have magical abilities, but instead specialized in martial arts. Mori preferred using Judo and Kendo techniques, while Honey was absolutely lethal in his own style of martial arts, and he was also proficient in ninjutsu, using shuriken, kunai, and various other ninja weapons when he needed to.

He never missed.

Mori preferred merely subduing his opponents, but Honey destroyed them.

Luckily for Honey, Lucy had never forced him to torture or kill his opponents like some of his previous masters had.

How's that for stereotypes? The Hare was more dangerous than the Wolf.

And heaven forbid Lucy call upon his key when he was sleeping. Luckily, Lucy was usually quick enough to summon Mori before Honey destroyed something.

Eventually, she realized that she had been staring at the group for a long time, and shook her head.

Her spirits would always surprise her, it would seem.

Jack laughed joyfully as he threw a snowball at a little girl, who fell and erupted into giggles.

He had been running the ice sculptures booth, but Lyon Vastia from Lamia Scale had come to relieve him so that he could enjoy the fair for a while.

"Again, again!" she cheered, bright green eyes looking at Jack pleadingly.

The Winter mage smiled at the adorable little girl, and he ruffled her blonde hair playfully. "Having fun, Sophie?"

The little girl nodded enthusiastically.

"Oi!" a voice called, and Jack looked up to see a tall, muscular teen with gray hair and green eyes scowling at him.

"Can I help you?" Jack asked with a slow blink.

"Yeah, how about you stop knocking my sister over?" he said angrily, and Jack blinked at the unfamiliar accent. Was that…Australian?

Why didn't his little sister have the same accent?

"We were just having fun." Jack explained, raising his hands up to try and placate the guy. "We were having a snowball fight. Right, Soph?"

The blonde grinned widely as she nodded her head, and Jack almost cooed as he noticed her front tooth missing, which made her smile even more adorable.

The older male (probably about 22 years old) scowled at Jack. "Leave her alone."

Jack scowled back. What did he do wrong? His main job was to make sure the kids had fun, and he had been doing that!

"Geez, Kangaroo, better find a specialist to remove that stick; I think it's pretty far up." Jack said, before smiling at Sophie sadly and waving goodbye.

Aster was too shocked to respond to the nickname and insult.

He was annoyed to see that Sophie was pouting as she waved goodbye to her new friend.

"I'm a bunny!" he huffed indignantly, before gently grabbing his sister's shoulders and turning her towards him. "Don't mind him, ya little ankle-biter. He'll give ya frostbite."

He ignored her confused expression as he guided her to the booth with the paintings.

After all, that was what he came here for.

Ryder was having a decidedly better time.

"Ready, bud?!" he asked Toothless, having to shout to be heard over the wind.

The Night Fury warbled in agreement, looking just as excited.

With that, the pair launched up into the air, reveling in the wind blowing around their faces.

Freedom.

Ryder sighed in content.

"Let's get this show on the road."

From the ground, a blonde girl was staring at the two in shock.

Was that…Hiccup?

Still on that blasted beast?

PERFORMING?!

She snarled viciously, ruining her otherwise attractive face.

Stoick would be hearing about this.

With that, she ran to the docks, where she would soon be picked up by one of the Hairy Hooligan tribe's ships.

She couldn't know that the chief wouldn't believe her claims, positive that his former son wouldn't be able to survive out on his own. The other Vikings would laugh at her, shaking their heads and taking her less seriously every time she tried to convince them.

It would be years before they swallowed their words.

But Astrid knew.

And she prepared.

Charlotte bit her lip lightly as she glanced over the crowd.

"Are you ready?" Lucy asked.

The blue-eyed beauty looked at the other girl and nodded.

With that, Lucy summoned Lyra, the Lyre spirit, and the three girls walked up onto the stage.

Lucy's guild mates looked at the group curiously. Some of them recognized Lyra (who was a big help in getting Asuka to sleep), but who was the other girl?

Lucy smiled as she sat down at the piano bench.

Lyra set down her lyre next to her, and Charlotte raised her violin.

The three girls began playing without a word.

(They're playing the Fairy Tail Main Theme Song)

When the girls finished playing, the audience was silent…

Until thunderous applause nearly deafened them.

"Who is that?" Jet asked curiously later on after the performance had ended.

"Oh!" Lucy said. "Everyone, this is Charlotte Phantomhive. Charlotte, everyone."

The girl smiled a bit and curtseyed slightly in greeting.

The mages were struck by her beauty, especially the males.

Charlotte had long dark blue hair and sapphire blue eyes. She was wearing black jeans and a dark blue blouse, along with a black jacket and fingerless gloves. She also wore a black combat boots and an odd silver ring with a large square sapphire gemstone.

"Phantomhive?" Cobra asked, eyebrow raised as he examined her appearance. Unlike most of the males, he wasn't staring because he was attracted to her, but because he recognized her surname.

Charlotte's smile became slightly fixed. "Yes. Countess Charlotte Angela Rachel Phantomhive."

Lucy smiled at her sympathetically as the others looked at her in surprise. "Charlotte was looking to join a guild, and we've known about each other for years, though we never met, so she came to me when she heard I had joined Fairy Tail."

"I saw a flier for this event on her desk, and I asked if I could help." Charlotte added. "Lucy told me that she wanted to play that song, and that it would sound better with a lyre and violin accompaniment, and I just so happened to know how to play, so she taught it to me."

"What was that song, anyway?" Reedus asked quietly. "It was beautiful."

Lucy blinked away her tears at hearing that statement, and smiled at him gratefully. "Thank you. I wrote it when I was ten in memory of my mom."

Reedus' eyes widened in surprise and sorrow for her loss, but he wasn't particularly surprised.

The best art was inspired by the artist's loved ones.

Half an hour later, the group stood in the guild hall. They would clean up from the event later.

"Where would you like your guild stamp?" Kinana asked cheerfully.

"Don't suppose I could put it on my eye." Charlotte said dryly.

Cobra glanced at her again. So the rumors were true, then, or at least some of them.

The girl's father had been contracted to a demon, and the contract seal had been placed on his right eye, which he had purportedly covered with an eyepatch.

Interesting.

Charlotte blinked at the startled looks she received, before shaking her head. "Never mind, I was kidding. The same shade of blue as my eyes…on my left wrist, please."

The same side that her family's ring (the one declaring her head of the Phantomhive family) was placed on.

And with that, Fairy Tail gained another member.

Please review!

I know nothing about the technical aspects of music, playing an instrument, or anything like that. I added the mini-concert as a request.

Crap! Now I'm torn between Hijack (Hiccup and Jack) and FrostBunny (Jack and Aster). FrostBunny, or one of the variations of their ship name (JackRabbit, for example), is really disturbing when Aster is a Pooka/Bunny, but when he's human I like the pairing.

For those of you who are curious, Aster said that he was a bunny because he has a sort of shape-shifting magic that turns him into a Pooka, aka a giant alien rabbit. It's not exactly Take Over, because it's only one form, but it is a Transformation magic.

I hadn't been planning to bring him into the story, but now that I have…

Great. So! I'll put it up to a vote.

POLL! Should Jack be with Aster (Bunny) or Hiccup/Ryder?

Charlotte is my OC from the anime Black Butler, or Kuroshitsuji. Basically, she's Ciel and Lizzy's daughter. Ciel abandoned her and Lizzy because he only needed an heir to continue the family line. She grew up with her mother, and was mentored by her father's old maid, Mey-Rin. She holds noble titles on both sides of her family (Countess for Phantomhive) and is very well-off financially. She's boring in this chapter, I know, but I'll flesh out her character later on. For those of you who know about Mey-Rin's past, considering she's Charlotte's mentor…well, Charlotte has an interesting skill set. ;)
