Chapter 1: Happy Birthday!

It was a dark and stormy day.

Of course, it was always a dark and stormy day here in Demon World. She sighed heavily as she watched the dark clouds drift by in the red sky. One might think this was an awful place for a fairy to live, but it's where she ended up.

She should be in Spirit World, where the rest of the ethereal creatures like her were, but that would mean she'd have to leave her one and only friend.

Her friend just so happened to be an Elfin, even more rare of a creature than she, so she took it upon herself to protect her. After all, she had magic to fight with. The small elf had nothing but her wits.

And what wits she had. Mari Krystal might have been small, but she had a big personality and a mouth to go along with it. Never had she seen such an innocent face sport such a boisterous, wild attitude.

She supposed that's what drew her to the elf in the first place. That, and the ambitions of the small girl.

Heh, small. That word was relative since she, herself, could fit in the palm of Mari's hand. She could take a bigger "humanoid" form, but she preferred to stay like she was now, which was a towering three inches. Although, with her butterfly wings she looked a bit bigger. But even with that, most demons just swatted her like a common fly. How anyone could mistake her silver hair, which shown amethyst in the sun, and round cerulean eyes as a nasty insect was beyond her.

At any case, Mari's thrill for life brought much adventure to her timid self, specifically her need for discovery. Mari wanted to be a Demon World reporter, or announcer, just like her idol Koto. Her dream was to one day announce the next Demon World Unification Tournament. But for now, her drive was to get the latest "scoops" on the fighters.

There were two very specific fighters Mari wanted to interview. The two most infamous demons in all the realm.

Kurama and Hiei.

Of course, she secretly knew Mari wanted a scoop with the latter more than the former. Perhaps more than a scoop. She giggled. If she had to admit, she found the former rather attractive herself...

"Oh, I'll never get an interview with either of them!" she remembered Mari crying.

Indeed, Kurama would probably be an easier target since he lived in Human World, but Hiei was rarely seen at all except at the tournaments. It was funny. The two of them had quite a fan-base amongst the demonesses and the like.

She knew that Mari would die to interview them, or rather just one more than the other.

And that's why she was now in Alaric; Mukuro's land, risking her neck, and perhaps very life, looking for said target. It would be a slim chance, but she had to go for it.

And, as if on cue, she saw that mass of black running through the trees.

She blinked a few times. "NO WAY!" She gave chase and had a hard time keeping up. Thankfully her energy tracking was top notch and now that she had a lock on him, there was no need to really worry.

He wasn't getting away from her.

It took a while but she soon tracked him to the Human World and she watched in stunned shock as he entered a temple of some kind, appearing to join in on a celebration. "Oh, Mr. Hiei," a soft female voice chimed. She looked closer to see an ice maiden; a Koorime to be exact - very rare. Was this his secret girlfriend?

Or perhaps an awkward triangle as a large human male stomped up to the girl and began proclaiming all sorts of love to her. Hiei scoffed in disgust and turned away from the display. She was all for romance herself, but even she had to stop looking at it.

She continued to watch and saw the other famous demon was there. His long red hair and gorgeous emerald green eyes... No, focus! You're not here for him!

She shook her head of such thoughts and watched as a large group gathered around the small female and gave her a cake. She noticed one of them was none other than Yusuke Urameshi, son of Raizen and creator of the tournament.

She watched in sheer fascination as humans and demons alike started to sing "Happy Birthday" to the small maiden.

Well, what do ya know...

The green haired girl blushed in embarrassment and endured the song and they soon cut the cake. That's when Hiei started to leave. "Oh? Mr. Hiei...where are you going?" The birthday girl asked.

"I detest the lard in cake icing...I need some air..." he answered.

"You will be back though...right?"

Hiei paused at her question and she noticed his face soften ever so slightly. "Yes." And he walked out of the temple into the woods, soon flitting to a tree and relaxing on the branch.

Oh! OH! This was too good to pass up. Secret girlfriend be damned! She would just have to deal with it! Mari's wishes were more important to her. She flew to the tree he was residing in and hovered just in front of his face.

One morose crimson eye peeked open, not even acknowledging the rarity of her presence. "Shoo, bug," was all he said as he closed his eye again.

This was too easy. He literally saw her as no threat. Was he never taught how dangerous fairies really were? Oh, well.

Sucks to be him.

She grinned wickedly and started to chant.

"Twist the bones and bend the back.

"Itch-it-a-cop-it-a,
Mel-a-ka-mys-tic-a..."

His eyes snapped open. "What the hell?"

"Trim him of his baby fat.

"Itch-it-a-cop-it-a,
Mel-a-ka-mys-tic-a..."

He began to swat at her, but she flew back. Not far enough that he couldn't hear her, but out of his reach. "Damn pest!"

It was still too easy! Even now, he saw no threat! She finished her chant with a dramatic flair and a shower of flower pollen.

"Give him fur,
black as black.

"Just...
Like...
This!"

Blue eyes crept open with a yawn as she stretched her legs and crawled out of bed. Since she had no job, or anything to do as of late, she had been sleeping in a lot lately.

She combed her blond hair, minding her large elfin ears - those always got in the way - and brushed her teeth. Lightning crashed outside, startling her a little.

She should relocate to Spirit World, but there was too much excitement here! So many things to explore and discover! Spirit World was...well, dead in comparison.

Someday, she would be famous. Someday, her name would be known. Someday, people would see her for what she accomplished rather than, "Oh, look; a stupid little elf!"

She nodded as she finished her grooming and went to get something to eat. Just then, a knock at the door sounded.

"Hmm." She answered it and saw no one. "Hello? Is someone there?" A hiss made her look down and she gasped as she found a basket with a small, black kitten in it. "Oh, a little kitty..."

"SURPRISE!" She screamed and jumped back as her fairy friend, who was sporting her taller humanoid form, jumped and pulled her into a bear hug. "HAPPY BIRTHDAY, MARI!"

The cat in the basket flinched, but neither girl noticed.

"Oh, um? Thanks, Hana...but you got me a cat?" she asked.

The fairy giggled. "Not just any cat...a very specific cat..."

"Huh?" she blinked.

Hana giggled. "Let's just say, this cat is someone you will really want to meet."

Mari looked down at the feline in question. It seemed just then her brain decided to notice this cat had crimson eyes...and a very noticeable white starburst in the fur on it's head...

WHAT.

She looked back and forth from the cat to her grinning friend and finally face-palmed.

"Hana Himawari...WHAT DID YOU FRIGGEN DO?!"

~To Be Continued

A/N: Oh, noes! What HAS Hana done? What will Mari do now that Hiei is in her clutches? Will anyone else figure out it's Hiei's birthday, too?! So many questions!

Speaking of questions.

This is actually going to end up being a Q&A eventually. So if you want to submit questions in your reviews, PLEASE do as we need them for plot and humor :)

Mari is pronounced Mah-ree, not Mare-y. The cat chant in here was from Hocus Pocus.

Hope you enjoyed it! See you soon!
