/Author's Note/

Another Gray/Natsu story! Inspired by "Tokyo Mew-Mew" manga. Because Ichigo in that manga looked so cute with her black neko-ears on her pink hair. Those colors match pretty well~.. Hahaha..^^

Sorry for every mistakes in grammars and spellings..^^;

Fairy Tail belongs to Hiro Mashima. Not mine.

Chapter 1 / It Works!

Levy had just back from her mission with Jet and Droy last week. She was very happy since she got a new magic book from her client as a present. A week had passed, and now she's in the guild tried to practice her new magic spell she had learned from the book.

"Levy, I heard you've learned a new magic spell." Lucy approached a table where Levy sat, surrounded by almost every members of Fairy Tail who wanted to see her showing the new spell.

"Yep!" Levy smiled. "I was just gonna show them the magic. You could see it too. Come here, Lucy! Hehe.."

Lucy excused herself from the crowd and sat next to Levy. The blonde saw a black little kitten and a frog on the table. "So, what kind of magic is it?"

"It's called 'Inserto'. You could insert one's personalities and abilities into other. I learned it from this book, got this as a present from my mission before." The petite girl giggled. "But I haven't mastered it too far. In fact, this is the first time I'm actually gonna try it with living creatures, starting with these two." Levy pointed at the kitten and the frog. "I'm gonna insert this kitty's personalities and abilities into this frog."

"Good luck, Levy!" Jet shouted, followed by Droy. "You can do it!"

Meanwhile, on the other side of the guild, we could see Natsu and Gray were fighting for the last piece of sausage.

"Give it to me, ice-block!" Natsu shouted.

"You already ate 7 sausages! So this is mine!" Gray took the sausage.

"What? But you too had eaten 7 sausages!" Natsu kicked Gray's stomach, making the raven flying backward, and grabbed the flying sausage.

Back to Levy's table..

Levy took a deep breath and exhaled. "Okay.. Here I go!"

She closed her eyes and murmured the spell. Her book was floating in front of her and suddenly there were some yellow light surrounding her. Everybody was very focused to her, not paying attention to the two boys who were getting closer to them.

"Welcome, sausage~!" Natsu threw the sausage to the air and opened his mouth widely, but soon realized that Gray was already behind him.

"Crap! I'll just have to burn you first before eating my flying sausage! Fire Dragon's Claw!" Natsu immediately burned his hands with fire.

"Oh no you don't!" Gray shouted as he tackled the fire mage.

Levy was now ready to give it a shot. "Magic Book activated..." The black kitten was surrounded by light. The petite girl pointed the enlighten kitten and shouted, "'INSERTO'!"

"Whoaaahh!" Because Gray tackled Natsu a little too hard, the rosette hit the table where the frog was and made it ran away.

"N-natsu look out!" Lucy screamed as she realized what's gonna happen.

"M-my book... It's..burned.." Levy sobbed. Yes, because Natsu was hit by the light that blinding him for a moment, he accidentally shot his Fire Dragon's Claw and burned Levy's book into ash.

"Levy, I'm sor-" Before Natsu could say sorry, his body was suddenly glowing. "W-what's happening?"

The guild engulfed by the light and everyone shut their eyes tightly.

"Ouch, my eyes.. Hey flame-head, you okay?" Gray rubbed his eyes while approaching Natsu, his vision was still a little bit blur.

"Gray?" Natsu saw the raven was already standing in front of him. "Yeah.. I guess so. I don't feel anything...different at all." Natsu looked at his hands and moved his fingers.

While the others in the guild were very shocked seeing Natsu's condition after getting their vision back to normal.

"N-natsu..." Lucy finally spoke shakily. "Something's...not..r-right.." She pointed at the rosette.

"What do you mean?" Natsu confused. He felt something was twitching oh his head. "What's this? Fluffy e-ears?" Then he turned his head nervously and saw a 'black fluffy tail' was wagging on his back. Silence...

"Yes! It works! The 'Inserto' spell's working!" Levy suddenly shouted happily, forgot about her book and broke the silence.

"Levy! What are these things?" Natsu pointed his new black fluffy ears and tail. "Get these things off of me!"

"But I...don't know how." Levy shrugged. "It's written in the book you accidentally burned. There." She pointed at the ashes. "And I haven't read how to dispel the magic yet. I didn't expect to apply it on human, until you suddenly hit the table where the frog was supposed to be one which took the magic effect."

"Where did you get that book, Levy? Or maybe you have the copy?" Gray asked.

"I don't have the copy. I got that book as a present from finishing my mission a week ago. It's from the nobleman who lives in the next city near the mountain." Levy sighed. "All I know is, don't let the 'victim' gets too emotional-"

But everyone in the guild had already surrounded Natsu, touching his fluffy black neko-ears and tail.

"It's so cute~.." Mira giggled touching Natsu's left neko-ear.

"Wow. It really is fluffy." Lucy touch his right neko-ear.

"Could you also fly like me, Natsu?" Happy flew happily above him.

While the guys were busy observing his tail. "Natsu! Wag your tail! Hahaha!"

Natsu blushed, he felt totally humiliated. Finally he bursted out his anger. "STOP THAAAATT!"

POFF~!

"N-natsu?"

"Meow?" (What?)

Now everybody was definitely staring at him.

"Meow? …Miaw miaw?" (Guys? Uuh.. Why do you look so tall?)

"What did I just tell you.. about not getting too emotional?" The blue haired girl stared disbelief.

"M-meow?" (H-huh?) Natsu's sweats dropped.

Me: Neko-Natsu is so cuuutee~.. *drooling*

Happy: I have a little brother now! Yeeaaayy! *flying happily*

Neko-Natsu: Mrawr! (Dispel this stupid magic at once!)*trying to scratch my face*

Me: It's all your fault for burning Levy's book. She couldn't dispel it now without her book.

Gray: *grabing Neko-Natsu* Now, now.. You should stop doing that threatening things, flame head. It's no use since you're just a black little kitten right now. Hahaha.

Neko-Natsu: M-meow! Miaw miaw! (P-put me down, ice block!)*struggling but fail*

Gray: Sorry, flame head, but I don't speak 'kitten-language'. Hahaha!

Happy: But I could understand him well!

Me: Of course you could, dear Happy. You're a cat after all..

Happy: …You're right! I've never thought about that before. Hahaha.

Everybody: …

Me: Anyway, off to the next chapter, guys~! ^^

Neko-Natsu: Meow! Miaw miaw meeeoow! (H-hey wait! What about meeee..!)

A/N: 'Inserto' is from Latin language means 'Insert'. Haha..
