Miyuki's Adventure in Katekyo Hitman Reborn

Chapter 1: The Mad Scientist Who Was Obsessed With Anime

"Kufufu!" A black haired girl laughed maniacally."Finally, I finished!" She held a black bracelet in her right hand."I am Sakura Miyuki, the world's best scientist and inventor! I have finally finished the most ultimate and best creation ever." She proclaimed to herself in a loud, obnoxious manner. She flipped her long, silky black hair over one shoulder.

"More like the world's craziest scientist and inventor in the world." Another girl spoke, rolling her yellow eyes.

"Hey, I'm not that crazy." Miyuki pouted. "It's really the best creation I ever made, Aoi-chan..."

"So what's your great creation?" Aoi asked nonchalantly. "And stop laughing like that. Where did you learn to laugh like that anyway?"

"Kufufu! I'm glad that you asked, Aoi-chan. It's Rokudo Mukuro-sama's laugh. He's one of my favorite characters in Katekyo Hitman Reborn, which is an anime I love." Miyuki explained excitedly. "He was Tsuna's enemy but then became his illusionist and mist guardian. He and Chrome-chan share the same body becau-" She was soon cut off by a frustrated Aoi.

"Stop, please don't say anymore! He is a character from one of the anime you like. I get it, so please stop!" Aoi shouted, frantically covering both of her pointy ears. (Not that it could block out Miyuki's obnoxiously loud voice; Aoi was beginning to think that the whole world could hear her.) "Just tell me what you created." She sighed exasperatedly.

"Well, you sure are impatient. I created a vortex that can take me to any world I want! It looks just like an ordinary bracelet, but if you say the password in your mind and then say where you want to go, or what world you want to go to, it'll take you there." Miyuki explained to Aoi happily. "And guess where I'm going to go to!"

Aoi gave Miyuki a bored stare. "To the anime worlds, right? I can tell what you were thinking when you were creating something like that." She sighed, shaking her head. "Why a person like you likes anime so much is what I can't comprehend."

"Hey, if I didn't like anime you wou-" Miyuki was cut off by Aoi yet again. She really needed to stop that.

"- Wouldn't even be here." Aoi completed her creator's sentence. "Yes, I know that I was created because you were once obsessed with an anime named Chobits, and you created me because you wanted one." Aoi finished her explanation and gazed at Miyuki, slightly curious. "What the hell are you doing?"

"Huh, me?" Miyuki pointed to herself. "Oh, packing up to go to my first anime world." She gave a cheerful grin.

Miyuki was packing up her things. She was taking a laptop, a whole bunch of Japanese money, millions of manga, a tonne of clothes that were mostly of the Lolita fashion, and also a Namimori-chuu uniform.

In addition to that, she packed a cell phone, camera, and a bunch of marshmallows and snacks inside of her magical backpack which had an unlimited amount of space.

"Oh well, have fun." Aoi said, waving her hand slowly.

"Yeah, I will." Miyuki waved back jovially. She closed her eyes and chose her words carefully in her mind.

'I, the one who accepted this mission…' The bracelet let out a binding light. 'By the ancient contract, I order you to release your power!' A red magical circle appeared under her feet.

'The wind is in the sky, and the stars are in the heavens. And a resolute heart beats within my chest! This magic in my hand… World vortex set up! To the Katekyo Hitman Reborn world!' The magical circle around her feet went up and disappeared, along with her.

"Finally, peace and quiet." Aoi rejoiced half-heartedly and strolled out of the lab.

"This looks like Tsuna's room," Miyuki said to herself. "Where is Tsuna?"

Miyuki looked around the room and confirmed that it was indeed Tsuna's room. She wandered around all the way to the bathroom and saw herself in the mirror.

"Why in the hell do I look like Tsuna?" Miyuki screamed at her reflection. "Wait, does that mean I have that between my legs?" Her mouth hung ajar, honestly frightened.

Miyuki looked over herself- Tsuna's body -and saw there was nothing. It was completely feminine.

"Phew! Glad I don't." Miyuki sighed, relieved. She wiped the sweat forming on her brow. "But what's going on?" She added, confused.

Miyuki stood there and thought to herself for a few minutes. Her eyes widened as she finally reached a conclusion.

"Because I don't exist in this world... In order to be able to stay here, I would have to be inside another character's body!" Miyuki soliloquized.

Miyuki went through the morning routine and went to Tsuna's closet. It contained only boy's clothing.

The closet is only boy's clothes. This means, that since I took over Tsuna's body his body turns into a girl's one because I'm a girl. Does that mean I have to act like him too? Oh who cares, all is going well. She grinned as that problem was gone.

Miyuki went to her magical backpack and took out a strip of fabric. She wrapped the material firmly around her chest, making sure it lied perfectly flat. She then put on Tsuna's uniform.

"Tsu-kun!" A woman's voice called loudly.

Must be his mom, Nana. The scientist deduced.

Before answering her call, Miyuki tested her voice, making sure it sounded exactly like Tsuna's. "Yes, I'm awake." Miyuki yelled back in a slightly deeper voice. She was grateful for her vocal lessons, it also helped that Tsuna's voice wasn't exactly the manliest in the world.

Miyuki went downstairs and saw her 'mom'. "Morning, mom." She continued using Tsuna's voice and smiled.

"Good morning," Nana replied cheerfully, not noticing the slight differences in her son. "Tsu-kun, school is about to start, you should hurry up and go." She smiled as her child immediately dashed out of the house.

Miyuki ran to school almost getting bitten to death by Hibari. She acted as Tsuna the whole day and nobody noticed anything different, even though Miyuki hurt one of the bullies. They thought it was just luck.

Throughout the whole day, whilst hiding in Tsuna's body, she absorbed what was going on in his life before Reborn came and acted as Tsuna.

A few weeks later, Miyuki obtained her very own home-tutor/hitman/arcobaleno.

Omake

Sounds of waves crashing was heard. A lone figure sat on the emptied beach, she stared at the sky.

"I wonder how she's doing," The girl, Aoi, said to herself. "I hope she doesn't come back soon." She smiled coolly and watched as the sun set into the quiet night.

Before long, night came. A shooting star passed by and Aoi wished with all her might that Miyuki wouldn't ever come back.

Aoi was never a sweet, girly-girl.

Please review or Miyuki will use one of her crazy inventions on you!

The magical circle and the password are from Mahou shoujo Lyrical Nanoha. The last line is a bit different though.
