This fanfiction is also on Quotev, under the same title!

I apologize for any OOCness, I will be following the original Naruto storyline for quite a bit, however it will start to deviate pretty soon. I will also be skipping some parts!

Disclaimer: I do not own Naruto or any of it's characters! I only own my OC and where my plot begins to deviate!

Prologue

Minato and Kushina stood there, with the Kyuubi's claw through their stomachs, protecting their beautiful twins, Naruto and Ryuuko. Minato had sealed the Yin half of the Kyuubi into Mirai and the Yang half in Naruto. Though with the heavy injuries and the quickly depleting of both of their chakras, both Kushina and Minato knew they weren't going to live much longer.

Minato had sealed what was left of their chakras into both of their children's seals so whenever they needed them, they would have it. Kushina started crying and telling her children to eat healthy and grow up wonderfully and to stay away from Jiraiya and Minato added some words but told them to remember-even though they wouldn't- at all times, no matter what, Kushina and Minato would always love them and be with them.

Chapter One

12 Years Later

Naruto grinned at his latest prank and he was currently running away from the chunins that were chasing him around town. A yellow blur crashed right into him into an alley and quietly shush him. It was his sister, Ryuuko, or Ryu for short.. They were near identical. Both had blond hair and blue eyes but Naruto's blue eyes were a more darker color and Mirai's color was lighter.

Their personalities were completely different too. Ryu's personality was more like Minato's, however if she got angry, she would have Kushina's explosive anger and if someone close to her was threatened or she got passed angry, she would have Minato's calm anger which according to Naruto, was even scarier than explosive.

Ryu had inherited Minato's genius mind though Naruto, was a genius in his own way also. Ryu was currently an ANBU in training, but reluctantly by the Third Hokage. She had threatened to burn his Icha Icha books if he didn't allow her to join ANBU. He hadn't taken her seriously until she took out a lighter, found out where he had hidden his books and when he started chasing her, no one was able to catch her, even his top ANBU.

The Third Hokage had realized with dismay that Ryu had gotten a hold of a scroll that had Hiraishin and she also found her father's kunai and started using them too. He knew that soon, in a couple years, there would be another 'flee-on-sight' Yellow Flash in the bingo books.

When the chunins were gone, Ryu popped her head out of the alley and looked around, seeing no one she walked out of the alley and Naruto followed her. Naruto and Ryu both high-fived each other. "Another prank successful! It's all thanks to my genius pranking and your speed, sister!" Naruto grinned.

Ryu nodded in reply. "I have to go report to Jiji and report about my mission though. Don't do any massive pranks without me while I'm gone!" Ryu jumped up from rooftop to rooftop and thought about the mission she had just finished. The senile old man refused to give her any missions higher than B or A ranked.

Even if she was an ANBU in training, it didn't mean she couldn't handle anything above the missions. Her shishou that was the one training her had praised her about how she was soaking up all the training he gave her.

He had told her that she was almost as a prodigy as him when he was her age. However, her shishou never told her his name. She only knew him as Wolf or shishou. He never took his mask off while she was around but she didn't mind.

Ryu arrived at the Hokage Tower and knocked on the window, scaring the Hokage and made him raise the paperweight in retaliation when he noticed who it was. Ryu dodged and caught the paperweight. "Jiji, isn't this the tenth paperweight this month? At least I did not just poof into the office." She sighed.

"Well, come in and report to me of your mission." He replied. Ryu shrugged.

"It went smoothly as expected. Jiji, give me something harder to do." Ryu pouted. Sarutobi sighed and threw a packet at her. Ryu quickly looked it through and looked back at him with confusion.

"You will be joining the genin teams. You will be with Naruto, your mission is to observe the Uchiha survivor and make sure he does not fall into the hands of the wrong people, do anything necessary. Last resort is to kill him." Sarutobi said gravely.

"What about my ANBU training?" Ryu asked. Sarutobi reached into a drawer in his desk and brought out a mask.

"You have passed, with the approval of Wolf. Welcome to ANBU, Fox." Ryu's face lit up with a smile and she rushed up to the desk to get the mask. Sarutobi smiled. Even if she was a prodigy, she still showed childlike tendencies. It relieved Sarutobi. "However, you are not to allow the other team mates in your genin team to find out that you are ANBU, or even Jounin for that matter, not even your sensei should find out."

"Understood, Hokage-sama. Is there anything else?" Ryu asked. Excited to tell Naruto that she was now officially ANBU but doing well to keep her excitement in place. Sarutobi shook his head in amusement.

"No, dismissed." And with that, a bright yellow flash signaled the disappearance of Ryu. The instant she disappeared, an ANBU with a mask of that a wolf, stood in her place. Sarutobi looked at Wolf. "You know your mission then?" Wolf merely nodded. "Good, you are dismissed Wolf."

~The Kyuubi Twins~

After Ryu had gone to tell Naruto, she went to the farthest training ground and waited there for her shishou. It was only a couple minutes later that her appeared. She grinned and held out her mask silently. Trying very hard to hide her excitement.

Wolf reached over and ruffled her hair. "Good job. You've earned it." He said with pride in his voice.

"Shishou...can I hug you?" She asked shyly. Wolf chuckled and nodded. Ryu ran the couple steps and hugged him. She only really reached his slightly above his waist. He hugged her back and then stepped back. He knelt down to her height and stared into her eyes through the mask.

"I have a gift for you." Wolf reached up the his left ear took of one of his earrings and pierced it in her left ear. "To remind you of your training with me. Never forget what I taught you. Also that earring is special. If you send chakra to it, I will be alerted. The amount of chakra you send, tells me how badly I'm needed." He said with seriousness. Ryu nodded in reply and he ruffled her hair once again.

~The Kyuubi Twins~

It was the day of the announcement of genin teams and besides Naruto, sat Ryu. Everyone was looking at her with curiosity. Well, the boys were. The girls were mostly judging if she would be a rival for Sasuke's attention or not. Iruka walked in and both Naruto and Ryu waved enthusiastically at Iruka with wide smiles.

Iruka merely shook his head at both of them in amusement. Both of them in one team? Iruka felt bad for whoever was going to lead them. As Iruka started announcing the teams, Naruto and Ryu both were basically jumping out of their seats to know who they would be with.

"There will be one team with an extra team mate but this was the Hokage's decision." Iruka paused, noticing the girls that haven't been picked-except for Ryu-basically lean forward in their seat. A better chance to land in Sasuke's team they thought. "Team Seven...Naruto Uzumaki...Sakura Haruno...Sasuke Uchiha...and Ryuuko Uzumaki."

Every girl glared at either Sakura or Ryu. Sakura was jumping up in joy and Ryu honestly didn't care. She had been making observations on the Uchiha subtly. Thinking on how to approach him. When Iruka left and the Jounins took their assigned genin team. Team Seven was still in the classroom waiting however, hours later.

Ryu was getting annoyed by the minute and Naruto had set up a classic eraser in the doorway prank for the jounin-sensei. It was a couple minutes later when he walked in and fell for it. Naruto started laughing and Ryu stifled a giggle. She however started her observations on the jounin.

He had a mask that covered half his face and he used his Hitai-ate to cover his left eye. His gravity-defying silver hair, sent a twinge of deja-vu to her as she had a mental image of her ANBU training shishou, who also had gravity-defying hair.

The moment the jounin stated that his first impression of the genin team that they were all idiots, Ryu's annoyance flared up and she released a sudden high amount of killer intent that was slightly malicious, she realized what she had done and as quickly as it flared up, it disappeared. It happened so quickly that the only person who knew what happened was the jounin. Sakura, Sasuke and Naruto only felt a cold chill. Naruto just recognized it as Ryu's cold anger and turned to her with slight fear, and relaxed when he saw an impassive face and not a cold stare.

They had gathered on the rooftop of the academy when the jounin started speaking. "Alright, why don't you introduce yourselves, one at a time?" Sakura tilted her head to the side.

"Introduce ourselves? What are we supposed to say?" She asked.

"Things you like, things you hate, dreams for the future, hobbies, things like that." He replied. Ryu narrowed her eyes. 'What was she going to say?' She thought. Naruto piped up.

"Why don't you tell us things about you first? I mean before we say anything, so we know how it's supposed to work?"

"Me?" The jounin asked. The team nodded. "I'm Kakashi Hatake. Things I like and things I hate, I don't feel like telling you that."

"Huh?" Naruto and Sakura both said at the same time.

"Dreams for the future, I never really thought about it. As for my hobbies, I have lots of hobbies." Kakashi replied. Sakura turned to the group and with an annoyed expression said,

"Well, that was useless, all he really told us was his name." Naruto and Ryu nodded in agreement.

"Alright, your turns. You on the right, you go first." Kakashi said, jolting them out of their thoughts. Naruto grinned widely.

"Believe it! I'm Naruto Uzumaki and I like instant ramen in a cup and I really like the ramen Iruka-sensei got me at the Ichiraku Ramen shop but I hate the three minutes you have to wait for the ramen when you pour the water in the ramen cup. My hobbies are eating different kinds of ramen and comparing them and my future dream is to become the greatest Hokage."

"Next." Ryu rolled her eyes.

"The name's Ryuuko Uzumaki, call me Ryu. I like to train my skills to perfection and I hate ninjas that abandon their comrades. They are worse than scum! My dreams for the future, I really never thought about. My hobbies…" She hesitated. "Training." She said after a while of thinking. Sakura went next.

"I'm Sakura Haruno. What I like...uhh...I mean the person I like is...uh, my hobby is uh...my dream for the future is…" Sakura paused and squealed. Ryu's annoyance built up. 'What's so special about this damn Uchiha anyways? I can probably win a fight with him by just flicking his forehead!' She thought.

'That's because Tsunade-hime, took you in as an apprentice for a period of time, before you went into ANBU.' Kurama rumbled in amusement.

'...That is true. Kurama, I know you're already suppressing my chakra for me so it appears the amount of a genin, but how am I going to fight like one? Should I be using the Hiraishin at all? Or just rely on my speed...How does a genin fight anyways? Should I just pass off as a prodigy? Should I take into consideration of shishou's teachings?' Ryu asked Kurama. The Kyuubi thought about it for a couple seconds.

'Since the other me in Naruto is asleep, I can't ask to share information or Naruto might not be able to control the hatred when I wake up over on his side. You can always just make a telepathic link with Naruto and share his knowledge. You just need to ask.'

'Thanks, Kurama.' Ryu replied with a smile at the fox in the mindscape. She had become friends with the fox two years prior and she now relied on him like an older brother and Kurama was rather fond of her.

'Any time, kit.' He reached his tail and fluffed her head. Ryu returned back to the present with Sasuke ending his introduction.

"...and destroy a certain someone." Ryu mentally face palmed. She had lost her opportunity to learn about the Uchiha! Her mission was going splendidly. Kakashi started explaining about their first mission the next day and Ryu stopped paying attention, only noting down the area and time.

She reached out to Naruto, mentally. It was nothing new, they had both done this before and it was now pretty easily for them to do so. 'Naruto.'

'Ryu?'

'I just realized that I don't know how to fight like a genin. Could I possibly borrow your skills and knowledge?'

"Yea, sis. Any time. I'll always help you if you need it.' Naruto mentally grinned at her. Ryu grinned back.

-The Next Morning-

Ryu woke up with plenty of time to spare, used to her ANBU training times that made her often wake up at three in the morning. She quickly got ready and made sure she had her kunai bags and other bags on her then went to go make some breakfast for herself. By the time she finished it was nearing five so she went and woke up Naruto.

At five they went to the training area and noticed at Sakura and Sasuke were also arriving. "Hey.." Naruto said groggily. Sakura yawned in response. They stood there for a couple minutes and Kakashi had yet to arrive. Ryu slinked off to explore the training grounds, which took only a couple minutes before she was back with the group.

Three hours went by and Kakashi finally arrived. "You're late!" Both Naruto and Sakura yelled at Kakashi. He gave him the excuse of a black cat crossing his path and took the long way. Ryu was simply ignoring him. Annoyed that a jounin could be so lazy.

'Don't be so annoyed, kit. Also be careful of that killer intent of yours. Honestly, I had been annoyed yesterday and accidentally released some of mine with yours. I sure the jounin noticed the intense KI. Be careful, you almost blew your cover on the first day!' Kurama scolded. Ryu sulked and she missed how Naruto was hasty and attacked Kakashi before he even said 'start.'

"and….Start." Ryu instantly grabbed Naruto and hid to the forest, suppressing her chakra on the level of a genin's and telling Naruto to do the same.

"Naruto, we'll have to work together to get those bells. I won't be using my ANBU skills or that would be incredibly unfair. Let's do that formation we made formed together." Ryu whispered to Naruto.

Naruto nodded and grinned. Naruto leapt from the cover and ran towards Kakashi. He high kicked and Kakashi dodged. Ryu came from behind and kicked low, Kakashi jumped. Both Ryu and Naruto started unleashing a storm of kicks and punches.

"U-zu-ma-ki Barrage!" They said together. Kakashi dodged all of them but noted how well they worked together. Ryu reached for the bell and was able to touch them before Kakashi jumped away.

Ryu and Naruto frowned. "That didn't get him? I thought we perfected that!" Naruto whined. Ryu just shrugged. Ryu grinded her teeth together and made a quick decision. She quickly took out one of the Hiraishin kunai and before Kakashi could see what it was, Ryu threw it with surprising accuracy but Kakashi dodged. It flew to the side of his head and Ryu grinned.

With a yellow flash, she appeared in front of Kakashi and punched. He caught her punch easily and she kicked. He also caught that. She twisted her body and reached again for the bells, but however before she reached it, Kakashi poofed and there landed a block of wood.

"Substitution?!" Ryu said angrily.

"Sis! The bells are over here!" Naruto pointed to the bells under a tree and went over to grab them. The moment he bent down, a rope grabbed his ankle and lifted him way above the ground. Ryu saw her chance and dashed to the bell, ultimately being grabbed by another rope alongside Naruto.

Ryu started squirming around and snarling at Kakashi who had gotten the bells. He then went off into the forest, going for the other two. After a couple minutes, Naruto's stomach started growling. Ryu blinked. "Did you not eat breakfast, Naruto?"

"No..he told us not to." Naruto replied.

"Really? I still ate breakfast…" Ryu replied sheepishly. Naruto spotted the bento down at the floor, unguarded.

"Ryu, help me down!" He said to her and she nodded, throwing a shuriken at the rope that was holding Naruto and threw one at the robe holding herself. She flipped down and landed on her feet.

Naruto instantly ran towards bento and picked up a pair of chopsticks. "Itadakimasu!" he said happily. Ryu was sitting besides him, not bothering with the other bento when suddenly both of them felt a cold chill behind them. It was Kakashi.

"What do you think you two are doing?" With an eye smile that just merely sent another chill down their backs. In a blank panic, Ryu sent a large amount of chakra into the earring Wolf gave her. Kakashi suddenly flinched but it was so quick that Ryu almost missed it.

Kakashi caught both Ryu and Naruto before they could run and tied both of them to the post together and that was when the alarm started ringing.

Sakura and Sasuke appeared not long after. Sakura looking shaken and Sasuke all dirty. Kakashi sternly told them they currently all of them failed but they would have a second chance after lunch however, they were not to feed Naruto or Ryu. And he promptly disappeared.

Both Naruto's and Ryu's stomach growled at the scent of food and Ryu blushed in response. Sakura and Sasuke nibbled on the lunch but then felt rather guilty at the twin's growling stomachs.

"Here." Sasuke raised some rice up to Ryu.

"Huh? He told you guys not to though." She said to Sasuke.

"It's better if we share for a better chance at getting the bells, I don't want you two to be dragging the rest of us down. So have some." He replied. Sakura did the same for Naruto. Ryu's impression of Sasuke changed. Maybe he wasn't so bad after all.

Kakashi poofed in front of them with a furious expression, scaring all four of them. "You all…." Sakura and Naruto looked down in sadness. Sasuke tched his tongue and Ryu glared. "Pass."

All four of them stared at him in surprise. "HUH?!"

"Those who break the rules are scum..that's true." He said. "However, those who abandon their friends are worse than scum." Ryu narrowed her eyes. It was similar to what her shishou had told her.

Naruto's eyes started watering. "H-he's kinda cool, dattebayo."

"The exercise is over! Team Seven starts its first mission tomorrow!" Kakashi raised his thumb up.

"Yes!" Sakura said. Sasuke just had a smirk on his face. Ryu grinned. and Naruto started chanting,

"I did it!" over and over again.

"Let's go home." Kakashi said, turning and walking away. Sakura and Sasuke followed and Naruto started yelling at them.

"Get us off this post first, dattebayo!" They ignored him. Ryu sighed and slipped her hand into her kunai bag, quickly cutting them out.

"Naruto, you go ahead. I'm going to be staying around the training grounds a bit longer." Ryu said to Naruto. He nodded and went off after them.

~The Kyuubi Twins~

Ryu was training in one of the farthest training grounds once again. She was working on controlling the lightning element in her chakra and changing it. Her shishou had already taught her his lightning element jutsu but she rarely used it. He told her only use it when she had no other option but to do so.

She felt a presence behind her and she quickly turned with a chakra infused kick. Wolf jumped to avoid the kick and when Ryu saw it was him, she blinked in surprise and bowed. "I'm sorry, shishou. I didn't notice it was you."

"Nevermind about that, you called me earlier? I'm sorry I couldn't go to you, I was in an urgent business."

"Oh. I did so without thinking. I panicked and sent chakra without thinking. I'm sorry, shishou." Ryu replied. Wolf chuckled.

"Well, if I'm not needed anymore, I'll be going now." and he poofed. Ryu stared at the spot he disappeared.

'I'm no idiot, shishou.' She thought with a sigh.
