AN: This is my first Naruto fan fiction. It is based on the manga and anime but I will meddle with the events in my favor! The OC is my character at a Naruto RPG setting that I'm currently playing. I will attempt to combine the two worlds and smooth them out since originally my OC was active after the events of the anime. I feel like they would be a great match and a terrible one at the same time, so I thought it would make an interesting case. I hope you guys like it and also I would appreciate feedback! This is the pilot in which I mostly introduce the OC since...well we know pretty much everything about Itachi :P There will be a time skip since I am beginning early. Enjoy :3

Pilot

1.

Hyuuga Mirai sat peacefully on the verge of the cliff that offered a great view of her homeland.

Kusagakure- the village hidden in the grass. At the age of ten, she had a small, delicate figure and a porcelain complexion, fair and radiant. Her long black hair was carefully managed into a traditional style, exposing her big and pale eyes and her elegant facial features with intense cheekbones. Both her attire and posture indicated her noble lineage as she was dressed in a beautiful silky white kimono, properly arranged with every item necessary and she sat in seiza.

Mirai would soon take the Chuunin Exams, an impossible achievement for a ten-year-old kunoichi. She had completed her academy education at the age of eight with flying colors. She had spent the last two years mostly at training than going on to missions with the two other members of her team. She had been also learning the etiquette that fitted her social status as the sole heiress of the Hyuuga House of Kusagakure.

The girl always appeared timid and quiet, always sitting alone and studying rather than socializing and playing. She was a very serious child that spoke to impress even the adults and the teachers. She knew a lot of things about historical events, tradition, literature and arts, gardening and nature. Mirai never chatted with her schoolmates and never did she wander on the streets of the grass village like everyone else. She was the perfect child, always reserved and humble in her excellence, always obedient and well mannered. A perfect child, a perfect girl and a perfect noble. She had the top scores at the academy and no-one had ever seen her coming back from a mission or training looking hurt or at least tired.

Mirai was highly respected by her subordinates inside the Hyuuga House and a lot were expected from her. Her mother, who was unofficially the current head of the house, felt always proud of her daughter while her father trained happily with her on daily basis. The heiress was the spitting image of her father, possessing his big, expressive eyes and full lips but she wore the demeanor of her mother, distant and uninterested; probably the reason she had no social life during her years at the academy.

The wind blew from the south, upsetting only a few strands of her ebony hair. She breathed the rich fragrance of wild flowers and she focused her gaze on the tall, magnificent Sequoya tree that hosted the office of the Kusakage. Her eyes grew cold and piercing, as she remembered the last conversation she had with her mother.

"I believe it's the perfect time for you to become a Chuunin. I am sick of dealing with the villages expectations of you, Mirai. You are needed in the Hyuuga affairs and you could move more freely if you were Chuunin."

"Yes, Hyuuga-dono." Mirai replied firmly.

"It's also very crucial to do it this year, since the event will be hosted at Konoha, where our House originally belonged to. You must prove to those...relatives what a Kusagakure Hyuuga can become." she added coldly.

"I understand."

"After the stupid acts of your brother, Konoha thinks we are overruled. I will not accept their arrogance much longer, Mirai. You are much more competent than Hiashi's daughter. You could restore the glory of the Hyuuga Clan one day" her mother commented.

"Hinata-sama is still very young, Hyuuga-dono. She is considered a toddler." Mirai replied defensively.

"You could use proper taijutsu at her age."

Mirai nodded. She didnt want to argue with her mother and she was satisfied that she didn't continue speaking about her brother. Hyuuga Ichirou. The first-born son of Shizuka and Kisuke, her parents. Ichirou had been stripped off his honor as a ninja and became rogue after an attempt to assassinate one of the Fire Nation's political leaders, when Mirai was four years old. He then escaped prison with some of his associates and went missing ever since.

His image was burned in Mirai's mind. His face had the sharp features of their mother but the soft expression of their father. He and his younger sister were the polar opposites. She remembered his playfulness and radiant personality, always socializing and laughing and playing around. He was a genius ninja, becoming a Jonin by the age of twelve. Ichirou always promised Mirai that he loved her and often took her for a stroll in the city or a walk in the green forest. He would play hide and seek with her, teaching her how to be stealthy and sneaky and some nights he would even sleep by her side, stroking her hair and singing tenderly in her ears. He gave her a necklace the night before he was gone, that wrote one kanji: Love.

Mirai felt the weight of the same necklace around her neck becoming heavier as she thought of him. Love. What a romantic misconception, what a nuisance. Hyuuga Ichirou had lost his right to be called her brother since he abandoned her and the House, since he dishonored their principles and name, since he passed the burden of redemption and power on her.

The wind blew once more and Mirai's eyes focused again. She would travel in a few hours towards Konoha. She had no family there. The Konoha Hyuuga Clan wanted to destroy the Grass Hyuuga Clan although they were related and equally strong. She had no allies there. Her only comrades here were her two teammates: Asai Rin, a fourteen years old kunoichi with short brown hair and dark beautiful eyes that was very talented in ninjutsu and cooking and Yoshino Jin, a fifteen years old boy that was talented in fuinjutsu and making mistakes. She couldn't really say they were her friends, the age and interest gap made it impossible to communicate apart from strictly business level but Mirai cherished and protected those two with her life and -when necessary- with her name as well. Rin and Jin believed her to be quite weird and sometimes even scary, but they were loyal to their teammate and had proven that they would stand by her side at any cost. However, those two would take the exams as well and could not possibly leave the training grounds while in Konoha. She had nothing there but enemies.

The sun finally emerged, painting the grass golden and the village warm. She rose tiding her attire and then abruptly she stared at a random direction.

Mirai was always accompanied by Hyuuga Anbu so this was a game she was playing since she was little. She was amused by the idea that one day she would peer towards the right direction and make one Anbu wonder how on earth had she spotted them. After a few seconds her gaze dropped and she started to return to the Hyuuga district.

Her thoughts were focused only in analyzing the direction of the wind, the species of the flowers she met on the road and the sounds of the forest.

2.

Mirai was already settled in one of the guest houses inside the Hyuuga district of Konoha when the first assassination attempt was made against her. She was reading a historical scroll about the first shinobi war when she sensed murderous intention. She moved fast and took cover behind the bench of the small private garden as a barrage of needles fell on the spot she was seated only seconds before. She caught a scent of monkshood flower. Excellent.

"Leave now or be executed." Mirai warned, sounding as secure as always while her mind was calculating the odds. She sensed one target, adult. The person seemed to move irregularly which pointed her to believe that he or she -probably the latter- had no knowledge of the environment hence she was most certainly not a Hyuuga assassin. The young genin shed her heavy kimono and was left with the simple white robe that was placed beneath it. She had one kunai on her. Her opponent had to be better equipped and she should also possess more options in weapons.

Another attack came at her direction; this time the needles had tiny seals on them. None touched Mirai but she noticed the small symbols as those of chakra suppression. Mirai smirked at herself and relaxed her posture. The odds where in her favor.

She moved freely, avoiding another attack, this time with two kunai.

"Byakugan" She whispered calmly and the famous kekkei genkai was naturally activated. Ignoring the thin paper walls of the guest house she was able to spot her attacker. Obviously a female, with very normal chakra levels considering her age. Mirai hid out of the line of sight of her opponent.

"This is my final warning, miss. You are no match for me, they sent you to die." She tried to reason with the enemy, her voice still calm and soft. She didn't particularly care about her opponent's choice. She understood that it was only the first warning but truth be told… Mirai wanted to kill her. To think they sent such a weakling to scare her off, they had offended her.

Hyuuga Mirai was calm and quiet, timid and introverted, noble and elegant.

Hyuuga Mirai was also dead serious and lethal.

She counted to three and as her opponent made no move of retreat, Mirai moved through the walls, her eyes showing her were to hit. The woman that wore no headband died swiftly, her eyes becoming glassy, her features frozen in a final expression of surprise. Mirai stepped back and scanned the assassin's clothes. Nothing but typical ninja tools. Needles and poisons. Kusagakure ninja tools.

She closed her eyes slowly, deactivating her Byakugan. She drew one deep, quiet breath.

'Calm down.' she thought to herself.

Right then and there she sensed two other people behind her. She turned towards them.

Two Hyuuga Anbu of the Leaf Village were standing side by side. Both male, one wearing a fox mask and the other wearing a bird mask.

"Thank you for your assistance." Mirai stated.

The Fox spoke. "We will take her and report to Hiashi-dono."

"You are most considerate." She bowed humbly.

The Bird lifted the body effortlessly and with a small greeting both of them disappeared. Mirai stared at the floor where the enemy kunoichi drew her last breath. No blood. No marks on the floor. Behind her, two thin paper walls were ripped. She sighed and returned at the bench where she picked up her kimono and obi, placing them carefully around her figure again. The needles were missing. She gave a half-smile towards the direction the two Anbu had gone and took her seat once again, picking up her scroll. History absorbed her completely.

3.

The written exams were trivial. Mirai spent most of her time inside the room noticing the other contestants.

There were her teammates, Jin obviously copying Rin's answers. There were genin from the Leaf, the Grass, the Waterfall, the Sand and the Stone. 'Not a large variety', the girl noticed. She counted sixty six genin, seven of which were eliminated before the end of the exam because they were caught cheating.

She looked at her sheet again and shook her head.

Q: What are you skilled at?

A: Painting.

Q: What is your weapon of choice?

A: Needles.

Q: How many shinobi do you work with?

A: All genin work in three-man-squads.

Q: How many shinobi does your village possess?

A: I don't know.

Q: How many ninjutsu techniques can you perform?

A: None.

Mirai understood the nature of the test quickly. There was not a specific set of answers that were better than others. They were checking the genins' ability to reply realistically while protecting the real information. It was pretty similar to what Mirai had been doing all these years so it was easy for her. She was certain that Rin would catch up quickly and maybe reply playfully like she usually did. Jin -if he didn't copy Rin's exact manner- would go wild. She already imagined him writing that the Grass village had one million shinobi. She smiled at herself.

"Miss Hyuuga, are you finished?" A man asked her. She looked at his warm brown eyes and tanned skin. He wore the Leaf headband and the special ribbon on his arm that showed his status as a proctor.

"Yes. Thank you." She agreed as he took her sheet. He smiled at her kindly and showed her the exit. Mirai was taken aback by his gentle behavior. She returned a small smile and followed his directions.

As she was closing the door behind her, someone else held the door nob. She took a few hasty steps forward and turned only to see another boy leaving the room as well, with a small bow towards her as he silently closed the door behind him. They were alone in the corridor. This boy couldn't be much older than her but he was way taller. He wore black attire and Konoha's headband. He had long raven hair in ponytail and matching velvety black eyes with long dark lashes, splashing perfectly on his canvas-like complexion. His features were beautiful and gave away a reserved melancholy.

Mirai bowed back. Something in his presence was rather familiar but she wouldn't breach her quiet demeanor.

They stood opposite to each other, both of them close to walls. A few minutes passed and no one left the room. The girl started to fill somewhat uncomfortable but her features showed nothing of it. His expression was filled with apathy as he monitored the end of the corridor.

Some time later, she had focused on his vitals out of boredom. His heart rate was slower than normal and his breathing was quiet. His scent wouldn't reach her. His movements were few and discreet. His built appeared to be slim and slender but it was apparent that his body was far from fully shaped.

His aura remained familiar somehow, although Mirai was sure she had never met him before. Black hair, black eyes, fair skin, exceptional beauty. Konoha. Mirai turned her gaze on his eyes, almost expecting to see them turn red. A few seconds later he looked back at her, his examination still indifferent.

Could he be…?

"Uchiha Itachi" he introduced himself his steady voice rippling the silence of the empty corridor. It wasn't just a reply to her thoughts that he obviously had guessed but also a statement.

"Hyuuga Mirai" she declared.

None of them broke eye contact. Slowly their auras were filled with chakra, both of them asserting dominance. Her eyes lost their coldness and became fiery and his gaze turned intense. They were enemies by birthright, their families always fighting over control. A tradition that would be theirs to continue in the future. The Uchiha Heir of Konoha and the Hyuuga Heiress of Kusagakure.

People started to join them in the space outside the exam room but no one tried to interact with neither of them. They kept their eyes locked on each other for a long time, everything else was dulled.

Itachi moved at her direction smoothly and Mirai mirrored his motion. They reached handshake distance and the boy lifted his hand. She mimicked his movements suddenly aware that they were both breaking the good manners protocol. She didn't care at all.

They shook hands, both of them firmly and absolutely. When they stopped he bowed and left. The white and red fan, the symbol of his clan was embroidered on the back of his black shirt. Her eyes became distant again.

This should be interesting.
