The Uchiha Sister

Chapter 1: Tukiko

"Aniki!" a little five year old girl called. The little girl ran through her home searching for her oldest brother. She finally found him in the backyard practicing a technique. The girl smiled widely as she skipped over to her brother. "Aniki! Can you play with me?"

Her brother turned around to face her. Her brother was about six years older than her and he had long dark hair he always tied up in a low ponytail and dark kind eyes stared at her. He also had these lines that were on both sides of his nose. He smiled when his little sister skipped over to him.

"Maybe later, Tukiko. I have to practice or Father will get mad with me."

The little girl named Tukiko pouted. She looked almost like her older brother; she had dark, raven hair that shined blue in the sunshine and was styled in a short way with the back slightly sticking up and she had the exact same eyes as her brother. She was wearing a small dark blue playdress that her mother had forced her into.

"Why does Father always get mad when you don't practice, Aniki? You're only eleven years old!"

Her brother sighed before sitting down on the grass. Tukiko followed suit, leaning in on her brother.

"It's...complicated, Imouto. You're too young to understand."

"I'm not too young!" Tukiko argued, pouting. "I'm old enough to make my own choices!"

Her brother's lips twitched upward just a bit. "Five years old isn't old enough that you can make your own decisions. It's only when you're my age can you make your own choices."

"But that's in a bajillion years, Aniki!"

"Maybe so. After all, you are still just a child."

"But you're a kid too, aren't you Aniki?" Tukiko asked curious.

Her brother sighed. "Not anymore, Imouto." He stood to his feet and pulled his sister to her feet. "Now go run along so you can play with Sasuke. I have to return to training."

Sasuke was Tukiko's twin brother. They were exactly alike in many ways from their hair to their likes. If their mother dressed them up in the same exact clothes, no one could tell the two alike. Even the way they spoke was identical. The only thing that was different about them was their genders and their clothes. Because no one could tell them apart, their mother decided that Tukiko would no longer wear pants so she was always stuck in play dresses, no matter how much she hated it.

Tukiko pouted. "But I want to play with you, Aniki!"

Tukiko was caught by surprise when her brother poked her forehead with two fingers. She rubbed her forehead, pouting more.

"Maybe next time, Tukiko."

"You always say next time but you never have enough time," Tukiko muttered as she rubbed where he poked her.

"Sorry," her brother apologized.

"Itachi," a rough voice called from the house.

Itachi looked towards the house to see their father, Fugaku Uchiha. He was the leader of the Uchiha clan as well as the cheif of police in in the Konoha police. He was well respected in both their clan and in the rest of Konoha. He walked over to his son and daughter, narrowing his eyes at his son.

"Itachi, I believe it's time for your sparring session," Fugaku said, his voice monotone.

Itachi bowed. "Yes Father."

Fugaku nodded before leaving to the dojo where the two usually trained. Itachi sighed when he was gone and looked down at his little sister. She was staring at the direction their father had just left in, a frown on her face. Her eyes were glossy and it looked like she would cry soon.

"Aniki...why does Father ignore me?"

Itachi was silent. He did not want to answer his precious Imouto's question although he knew the answer. It was true that their father ignored Tukiko all the time. He ignored her when passing by her, when they were with their mother, even at dinner. The only time he knew he had a daughter was when they were with the rest of their family when they asked how Tukiko was growing in becoming a lady. When they asked about her, their father would always reply "She is turning into a most respectful lady, just like her mother."

But that wasn't exactly true. He didn't know how Tukiko was going with becoming a lady. Itachi knew that his Imouto hated everything that was girly from dresses to sewing. She was actually a tomboy at heart. Itachi figured that his Imouto had obtained her tomboyish nature from playing with her twin Sasuke and from playing with him. Either way, Tukiko just didn't like being a girl. Unfortunately for her, her mother and father decided from her birth that Tukiko would not train to be a kunoichi like their mother was before and instead study to be a noble lady. Tukiko was forced to take flower arranging classes like other little girls and even had to learn how to cook. She hated these classes but went to them with no complaints. And it would get worse when they were older.

Itachi had once overheard when Tukiko was just born and the clan elders and their father were discussing something. They spoke about how when Tukiko turned sixteen, she would marry a young boy from the Hyuuga clan. Now the Uchiha clan and the Hyuuga clan were not on good terms at all. Not as much as the Senju clan but still not on good terms. But the two clans decided that if they were to marry two of their children to each other then they would get along. If they were to do that then the two most noble clans of the Village Hidden in the Leaves would become one. The Hokage approved of this plan so made it possible for the two children to be engaged. Itachi didn't understand at the time because he was so young but now that he was older, he understood why his sister was to become a perfect lady.

It was so that she could be prepared for becoming a wife.

Itachi didn't know who was Tukiko's fiaance but he knew that his name was Neji Hyuuga. Tukiko didn't know yet that she was engaged but their parents planned to tell her on her sixth birthday. He felt so bad for his Imouto. All her life, she had dreamed of becoming a strong kunoichi just like him but knew her parents disapproved of it. That was why she kept her dream to herself. She even believed that one day her parents would give in and let her become a kunoichi.

That was mainly why their father ignored her. He didn't even want a daughter in the first place. He only wanted sons in his family so that they could carry on their legacy and he knew it would be a hassle to find a husband for their daughter. That was why he didn't want one. When Tukiko and Sasuke was born and after he arrranged the whole engagement to the Hyuuga clan, he practically ignored Tukiko. He would help with Sasuke and stuff but never with Tukiko. Their mother always asked Itachi to help care for Tukiko since their father wouldn't. He mainly focused on Sasuke and Itachi but never Tukiko. That's why Itachi was close to both his brother and his sister than the rest of their family. Sure, he's close to Shisui who's like a brother to him and he used to be close to their cousin, Obito but he died when he was two and with Shisui, it just wasn't the same. So Tukiko and Sasuke were the closest to him then anyone else in their family.

"Father does not ignore you, Imouto," Itachi only said.

"Then why does he never talk to me and ignore me when you and Sasuke are around?"

"Well...It's because your his only daughter."

Tukiko looked up at him, eyes glossy. "I don't like being a girl then. If I were a boy, he would acknowledge me and actually talk to me."

Itachi kneeled to his Imouto's height. "But you're not a boy so you have to understand this."

Tukiko frowned further. "But I don't like being a girl, Aniki. It's so-so lame. You have to follow all of these rules like you have to cross your legs instead of regular and you always have to keep them closed. Then you can't run around naked or anything because it's 'not ladylike'. And you have to learn how to cook, how to clean, do the laundry, you can't speak unless spoken to. I hate it! Boys always get to be messy, they don't have to be stuck inside all day and they get to beat up other people! I want to be a boy like you and Sasuke, Aniki."

Itachi couldn't help but chuckle. "There's something about girls that boys can't do, Imouto."

Tukiko tilted her head, curious. "Like what?"

"Well, boys can't bathe with girls, they always have to listen to girls, some boys can get beat up by girls, and boys aren't allowed to wear skirts. And girls can wear both pants and dresses."

Tukiko made a face, her tongue sticking out. "I'd rather wear only pants. It's annoying to wear frilly dresses."

He chuckled again at his sister's attitude then ruffled her hair in affection. "You say that now but later on, it'll get better."

Her eyes lit up. "Really?"

"Really."

"Well....Okay, I guess."

"Aniki!" a voice identical to Tukiko's called.

Sasuke ran over to his brother and twin sister excitedly. He was smiling and practically skipped over to Itachi.

"Aniki, can you teach me a new move?" Sasuke asked.

"Maybe some other time, Sasuke," Itachi replied. "I have to train."

"But you promised that you would do it today!"

"Tomorrow then."

Sasuke's shoulders deflated a bit but rised up again. "Alright! Tomorrow!"

At the exchange, Itachi saw Tukiko scowl. He knew she hated that Itachi was allowed to teach Sasuke new ninja move that were really cool and she only got to learn how to cook or something. She wanted to learn along side Sasuke but their parents forbid it.

Seeing how she was going to be upset, Itachi said to Sasuke,

"Sasuke, for today, why don't you play with Tukiko? She was asking me to play with her earlier but I simply don't have the time. Could you play with her instead?"

Sasuke turned to Tukiko, smiling. "Okay! I'll play with you, Kiko-chan!"

Tukiko smiled a bit but then scowled. "Sasu-chan, I told you not to call me Kiko-chan!"

Sasuke scowled as well, making him look identical to his twin. "Then don't call me Sasu-chan! Call me Sasuke-kun!"

She smirked. Then she stuck her tongue out at him and ran away yelling "You have to catch me before I can call you that, Sasu-chan!"

Sasuke growled but smiled widely. He ran out of the backyard, chasing his sister.

Itachi smiled at the two playing. Although the two twins acted like they hated each other, they were actually really close and almost always together. No Uchiha would see Sasuke or Tukiko by themselves unless Tukiko had her lady lessons. They were always together, even at bedtime and when Itachi was teaching Sasuke a move. The two slept in the same bed and got up at the same time. And when one of them had to go use the restroom, the twin would wait outside for them until they were done. They were the most adorable twins in all of the clans. Not even the Hyuuga clan leader and his twin could match the two Uchiha twins.

But then Itachi frowned. He knew that the two wouldn't always be together. When Sasuke would be old enough to enter the Academy, he would be so busy with studying to be a ninja that Tukiko would end up being lonely and by herself. Itachi hated the thought of his two siblings being seperated by that school and wished that Tukiko could enter as well. But he knew that it would never happen. He sighed. He knew that when Tukiko was told she was engaged at their birthday party and when she would meet her fiaance, Sasuke would have to be there for her since he couldn't. He also wondered how Sasuke would react to Tukiko being engaged...

Itachi shook his head and headed to the dojo to train with his father. Until the time came, he would just worry for his little sister.

So there's the first chapter! So...how did I do? I'm really new with the whole Naruto OC writing thing since I'm still rusty at that. I'm bad at making OCs. And I'm not sure if I can write for the Naruto section but I want to see if this story seems good or not. Oh! And I read about Mary Sues but I assure you that Tukiko is not an OC. I think. I'll have to check though. Well, that's it I guess. All I can say is review because I will not update unless I get at least one review. Okay?

So please review!
