It's just a few weeks before the third phase of the chunin exam. Sasuke's about to start his practice with Kakashi, while Naruto is forced to do the basics with Ebisu sensei .
Naruko and Jiraiya are training on perfecting her toad synchronized attack before going in a nearby inn. After a few hours of training, they decide to go and relax at the nearby hot springs.
"Hey senseeeei, while I'm in there don't you dare start peeping, I'll now immediately and you're gonna regret it. Got it? " said the blonde girl with a really dangerous smile. He was going to obey, first she was still a kid, second she was his student's daughter and third he knew she had inherited her mother's terrifying temper.
"Alright kid, just let me know when you're done with your bath".
Naruko wasn't really happy with her master's habits, but he was like her grandpa to her and she loved him. He and her brother were her only family and she decided to accept the unacceptable, as long as she wasn't involved. She even was somehow forced to read his books in order to tell him her opinion on them. Despite the perverted parts, the books weren't considered bad, but they gave her the opportunity to tease the old man about how inappropriate was to show these kind of things to a kid her age.
"Sure thing, Pervy Sageeee" she said purposely loud, in order to tease him again.
After finishing her bath, she covered herself in her towel and went to give him permission to do as he liked. What she didn't expected was to find a boy, having the spitting image of her, right there arguing with Jirayia sensei. It was funny to see the man fighting like a little kid with another kid. The boy was shouting at him for disturbing his training and demanding to be trained by him. After the shock of realizing who this boy exactly was, she couldn't help but let a giggle escape. This made the other two to turn their attention to her.
The boy too surprised to think just said "You look exactly like my sexy jutsu but younger. "
"Like whaaat? " both her and Jirayia said and within seconds she landed a punch on his head.
She then looked at her teacher and said "don't you dare think about it, old man".
Naruto then started attacking her and while being unable to land a single hit, he shouted "who do you think you are and you are punching me you baaaka? "
"I'm your sister and since my brother is embarrassing me by doing idiotic things I have to put him in place, baaaka. "
That stunned the blonde boy, but he couldn't deny it, she even had the same whiskers.
Jiraiya then explained that she really was his sister and told the boy that he would explain everything during the time that they would spend together while training him. After talking for a while with Naruko , it was decided that Naruto would continue his training with Jiraiya while she would return in Konoha with Ebisu sensei.
Walking back to Konoha, after being informed about everything by Jiraiya, Ebisu was still dumbfounded by the turning of the events that day. He even accompanied the girl to the Uzumaki temple before returning in Konoha. Unlike Naruto, Naruko was quite mature for her age, even though she was as energetic as her brother. He took the young girl for ramen at Ichiraku's, Naruto's favourite place in the whole village , leaving everyone that saw her gaping, and she instinctively knew that her brother had it really tough in the village. She then reached Naruto's apartment. Her first impression of the room was not the one she expected, the room was a mess. Clothes were thrown everywhere, the fridge was empty and only some empty instant ramen cans there were on the table. After she tidied up her brother's room, she studied for about three hours one of the scrolls, the Flying Thunder God Technique, and she decided to start training her speed for a beginning. She knew it would take much more time to learn it, and even more to master it, but she didn't want to lose time. However, before starting her training, she
knew that she needed to do something else first. She took out of her backpack a black purse with Konoha's emblem and looked at the inside to make sure that her money was at the right place. After falling in her sensei's trap quite a few times, she knew that she should be more careful with her purse. Jiraiya was really prone to the three prohibitions of the shinobi. He really had a weakness in women and also had a problem with overspending money and overdrinking sake. So Naruko as she was growing up, became extremely cautious with the small amounts of money that they were earning. At times like this one, she was really glad that she had brought a second purse just in case the sannin found the first one, which since she got the idea was always almost empty. She went then in the closest shop and she brought food for almost three months. Cooking it would probably be a problem, since she had never cooked till now, but she would deal with it later. She returned at the apartment to leave the things and then she left to start her training.
By roaming around she ended climbing a high mountain. It seemed peculiar to her that she sensed the chakra of others up there so she decided to go see what was happening. She didn't think that reaching the top would change her life once and for all.
When she reached the top she saw it. A masked white-haired man and a black haired boy around her aged. From Naruto's complains she could assume who both of them were. Then she had an idea. Having her chakra completely concealed, she decided to put into act her recent training. Within seconds she was sitting on the top of the nearby rock ,which probably was Sasuke's training target.
And then they saw her. After a few minutes of staring at her, Sasuke was about to say how of an idiot Naruto was for walking around like this, but Kakashi stopped him.
"Sasuke, this isn't Naruto, she's his sister, Naruko. "
"Oh, so you know me Kakashi San. "she said in a sweet and playful tone. "I didn't want to interrupt, I was just curious that there were others here while I was training "
"Is Jiraiya sama with you as well? "
"Well no. "Should I tell them or not? Hmm maybe not. Let's have my brother's training with him as a surprise hit, she thought, giggling in her mind. "Pervy Sage had some work to do so I'm on my own".
At the nickname Kakashi was trying not to laugh, but Sasuke was kinda irritated. She really seemed like the dobe's sister.
He decided to ignore her but the usual for him "hn" sigh triggered something inside her and she actually did get it, she did get why her brother was so competitive with this boy. In light's speed she was standing in front of him pointing her finger on his chest and saying "watch your attitude man, looking down on others won't make you superior ".Kakashi's mouth at the time was reaching his feet. Was it her standing against Sasuke, while all the other girls were going mad about him, or was it that her speed was almost like his master's ?Probably both. Sasuke on the other hand was off guard since she wasn't acting like her brother. She wasn't challenging him. She was lecturing him, and this annoyed him even more. However, deep down he was impressed by her, he would never admit it though.
"So what do you say, Kakashi-san? Can I help with the training? "
"Actually Naruko we've been training in a dangerous technique right now.. "
"What are you trying to explain sensei to the idiot's sister? "said Sasuke trying to infuriate her.
Her face was expressionless but in seconds she was behind him again, punching him like she did with Naruto a few hours ago. "First, I get it without explanation needed that the jutsu is like Kakashi's raikiri, second I'm quite capable of defending myself as well, especially since I'm not controlled by my emotions like you and third you're at the same level of idiocy with my brother so stop complaining. Or are you afraid of me.. Sasuke-kun? "
She hit a nerve after lecturing him for a second time within a few minutes, but before he could reply she looked at the masked jonin and asked "is it fine with you senpai? You'll be here after all watching over us. "
Kakashi could easily understand that emotionally she was at a jonin level. Despite her age and being accompanied by his favorite but perverted writer, she was fully in control of her feelings and seemed to be extremely rational even at the worst case scenario, so he agreed. However, he had the impression that deep down she wasn't similar to her brother only in looks.
She was smart enough to know that the rasengan was far to dangerous to be used in this training, especially since Sasuke had the completely wrong idea about what strength is. She admitted though to herself that he was smart and found cute things that other girls didn't even notice, like his awkwardness when he was scolded and his fast pace of thinking, but she hoped that fighting with her could make him understand that power comes from determination to protect and not from hatred.
