Ahem...I would start with the whole story of how the 9 tails was sealed inside Naruto, but everyone knows that story...so I'll do my version with my OC!!
Now on with the story...Thanks for taking the time and reading!!
Many years ago, two demon foxes existed. One with nine tails and the other with ten. When one tail was swung, it could destroy a mountain and cause a tsunami. To counter it, the people gathered ninjas. One person sealed the two monsters in a life or death battle and died. The foxes were sealed inside two newborn babies. The ninja who sealed them was known as The Fourth Hokage.
–Twelve Years Later–
Naruto Uzumaki and his twin sister Tora were running through the streets of Konoha, hoping to lose the ninjas who were hot on their trail. They had just finished painting all over the Hokage monument.
"Hey! Naruto! Tora! What have you done?" asked a ninja who were chasing the duo.
"None of you could do that! Only us, The Uzumaki Twins could!" Naruto shouted while jumping from roof to roof. Finally, after another ten minutes of running Iruka had caught up to them.
"What are you doing Iruka-Sensei?!" Naruto asked.
"No, what are you doing during class!" Iruka retorted.
Iruka was the twins sensei at the Ninja Academy they attended. They looked up to him like a father. The two lived alone with no other family, and had gotten harassed by ninjas and villagers alike for what was sealed inside them. Tora, who had attended the girls academy had gotten kicked out due to her making a floral arrangement...and then blowing it up. She seemed to have a knack for explosives..and swords. Girls later joined when they were done with the girls academy.
Iruka had finally gotten the two tied up and brought back to the academy.
"Naruto you failed the last final exam and the one before that! You shouldn't be fooling around." Iruka stated infront of the class. Naruto just closed their eyes and acted like they didn't care. Tora was sitting with Sasuke, smirking at her brother's misfortune. Finally Iruka had lost it. "We're going to have a review test for the transformation technique! Those who have already passed will have to line up as well!" Many protests were heard. Everyone lined up.
"Haruno Sakura going! Transform!" A pink haired Sasuke fangirl announced, before transforming.(A/N: You know what everyone looks like and what they wear so I won't waste time and explain it.) God how Tora hated her fan-girly-ness. As much as she hated to admit it, Sasuke was a really good shinobi and dare she say it, he was really cute! "Did you see Sasuke-kun!?" Sakura asked before going to the back of the line.
"Next, Uchiha Sasuke!" Iruka announced. Sasuke walked forward and transformed perfectly. "Good. Next, Uzumaki Naruto!"
Naruto walked to the front and transformed into...a naked girl, An adult version of Tora to be precise. Iruka-sensei had a nosebleed. (A/N: Tora has tanned skin, three whisker marks on each cheek, thick and straight shoulder length blonde hair like Sakura's after she cuts it, she has bangs, electric blue eyes like Narutos, she wears a black vest with a red thick stripe of red on the chest area, and black slightly tight shorts.)
Naruto changed back and started laughing, "I call that the sexy technique!"
"NARUTO!" Tora yelled before hitting him over the head. She was as red as the tomatoes she loved so much.
"Don't invent such a dumb technique!" Iruka yelled, with two pieces of tissue in his nose to stop the bleeding.
Later the two found themselves cleaning up the Hokage monument.
"Your not going home 'till you clean it up good." Iruka announced watching the two.
"We don't care! Its not like there's someone waiting up for us!" Tora exclaimed. Iruka's face softened.
"Tora? Naruto?" Iruka asked.
Said twins looked up. "What?"
"Well...If you clean that up, I'll treat you to some ramen."
"Really?! Then we'll do our best!" They both exclaimed while moving at an alarmingly fast pace.
Iruka, Tora, and Naruto were sitting in Ichiraku's eating ramen.
"Why did you vandalize such a place? You do know who the Hokages are." Iruka asked while looking at the duo.
"Of course we do. A person who receives the name of Hokage is the greatest ninja in the village. And I heard the Fourth is a hero who protected the village from two monster foxes." Tora stated while looking at her ramen.
"Then why did you guys-" Iruka was cut off by Tora.
"I'm going to be hokage one day. And surpass the others. I will make everyone in the village see my power and then they will know who Tora Uzumaki is!" Tora finished her speech and finished her ramen. "By the way sensei. I have a favor to ask." Naruto was to busy eating to hear anything that was going on.
"What is it Tora?" Iruka asked.
"Can I try on that Konoha forehead protector?"
"Oh this? No, this is proof that you graduated and are a real ninja. You'll get yours tomorrow."
"I want another bowl!" Tora exclaimed making Iruka laugh.
–The Next Day-
"We will now start the final exam" Iruka stated smiling at the students. "If your name is called go to the classroom next door. The subject will be the replication technique."
'Crap...Naruto can't do that technique!' Tora thought.
"Uzumaki Tora"
Tora walked out of the classroom and into the examining room. She greeted everyone and bowed to the Hokage.
"The Replication Technique" Iruka stated. Tora nodded and did the hand signs. Three perfect copies of herself appeared. Everyone smiled. "Congratulations Tora!" The Hokage announced. "Please come pick your headband. She walked to the front and looked at the different headbands, bandanas, forehead protectors, Navy and black gloves. She picked up a black glove and put it on.
"You are now a Konoha Genin." Iruka said proudly. Tora bowed, said her thanks and left.
"Good Job Tora! She heard many of her friends say. She thanked them too and walked over to her seat. Naruto was inside the other room. About five minutes later she heard Iruka yell he failed.
All of the Genin went outside awhile afterward to see their parents and Tora reluctantly followed. Naruto was probably sitting at the swing sulking. She looked in that direction and saw him. Sighing she started to walk over. When she was halfway through the crowd she ran into someone. She was falling but she didn't hit the ground. Someone had caught her hand and was setting her straight.
"I'm sorry! I was running to see my brother and didn't watch where I was going." She said while bowing.
"Hn. Don't worry about it." Tora knew who it was at the 'hn'. She looked up and saw Sasuke walking away. Shrugging, she looked back at the swing to find it empty. It was strange, but Tora just shook her head and made her way home.
Tora making ramen at home for Naruto and herself when there was a knock on the door. She washed her hands and answered the door to find Iruka.
"Oh, Iruka-Sensei. What can I do for you?" Tora asked, her brows knitting with worry, knowing It wasn't often he visited.
"Naruto. Is he here?" Iruka asked, clearly out of breath.
"No. Is something wrong?"
"Naruto has taken the Scroll of Sealing!"
"No Way!"
"Will you help me find him?"
"Hai!" Tora dropped her hand towel and jumped onto the roofs of Konoha.
After an hour of searching, Tora met up with Iruka.
"Forest." Tora uttered while running there with great speed. When she reached a small clearing, Tora found Naruto and Mizuki.
"Sensei?" she asked. Suddenly kunai was being thrown and she was pinned to the wall of the small house behind her.
"Give me the scroll Naruto." Mizuki demanded.
"No Naruto! He used you to get the scroll!" Tora exclaimed, realizing the situation.
"Your sister is just afraid of you being more powerful than she is!" Mizuki exclaimed.
"That's not true Naruto!" Tora yelled while taking the kunais out of her leg and arm.
Iruka showed up at that moment. "Naruto don't believe him!"
"What's going on here?" Naruto asked.
"I'll tell you both the truth. A rule was created after the incident that occurred twelve years ago." Mizuki started.
"Don't!" Iruka yelled while standing.
"A rule that only you, the Uzumaki twins, can't find out about. The rule not to say that Naruto is the nine tailed fox, and Tora is the ten tailed fox."
"What?" Tora whispered to herself.
"In other words, you two are the demon foxes that killed Iruka's parents and destroyed our village. You have been deceived by the village all this time. Didn't you think it was odd for the village to hate you so much? Even Iruka hates you!"
Blue chakra began to form around the twins. Iruka stopped moving.
"Die!" Mizuki screamed while throwing a large shuriken at them. Iruka jumped infront of them and stopped the shuriken. It was now imbedded in his back, Iruka coughed up blood.
"Why?" Naruto asked tears leaking out of his eyes.
"Because you're the same as me." Iruka answered. "You both grew up without the love of a parent. You were lonely right?" tears began to leak out of Iruka's eyes.
Naruto and Tora didn't know what to make of the situation. They were monsters. Murderous monsters. They ran. After awhile they stopped and sat behind a tree. Tora could sense the chakras of both Mizuki and Iruka. They were talking.
"Why do you go so far for such weak brats!?" Mizuki demanded.
"They are not weak and they are not brats! They are students I recognize..Each with their own ability they excel in, they are far from weak." Iruka replied calmly.
"DIE!" Mizuki yelled. Naruto and Tora immediately ran from their hiding place. Naruto punched Mizuki, sending him flying. Tora ran toward Iruka checking him for injuries. Then at least a thousand Narutos materialized.
"Nii-san..." Tora whispered as Naruto began to beat Mizuki to a bloody pulp. "NARUTO!" Tora yelled getting his attention after a while.
"What is it?" Naruto asked wiping sweat from his brow.
"Leave some for me.." Tora replied smirking. Mizuki's face twisted in horror, and Naruto smirked walking toward Iruka and bringing him far away.
"Please! I beg of you! Anything but that!!" Mizuki pathetically begged.
"They don't call me a number one rookie for nothing.." Tora said while adding extra chakra to her feet and around her body. A small hum was heard and a red light surrounded Tora. Closing her eyes she did a one handed 'kai' sign and brought it up to her face, keeping it there. The red light shot in a straight line towards the sky. Suddenly Tora opened her eyes,"DETONATE!" The red light that surrounded her exploded all around her and completely destroyed anything in it's path. When it was safe she took off her chakra guard and looked around. "Too much chakra I think...Oh well..." The explosion was so powerful and used so much raw chakra it set fire to nothing, only caused it to disintegrate. (A/N: I dreamt about this Jutsu and had to do it...now it's her signature one...just like how Naruto has the Rasengan and Kage Bunshin. I'll explain about it more at the end)
"Too much chakra I think..." a voice said from behind her.
"Iruka-Sensei, are you okay?!" Tora asked running towards him and fixing his wounds yet again.
"Fine...Naruto! Come over here for a second." Iruka asked while motioning Naruto towards a tree. Naruto walked over. "Close your eyes." Naruto obeyed. Iruka took off his own forehead protector and then took off Naruto's goggles, and handing them to Tora. Then he placed the forehead protector on Naruto. "You can open your eyes now Naruto."
Naruto looked around and put a hand to the forehead protector. "Sensei? This is your forehead protector..."
"Congratulations. You graduate!" Iruka said smiling really wide.
"Congrats, Nii-San!" Tora said watching him hug Iruka.
Tora was sure Iruka-Sensei was going to tell him how it only gets harder from here. But, she knew he'd wait until ramen...
Okay!! Now to explain the explosion of doom...
The Exploding Jutsu uses raw chakra, meaning that it isn't manipulated in anyway. A regular jutsu manipulates chakra to take a shape or form of something. Anyway, When Tora says 'detonate' the raw chakra that surrounds her seemingly explodes, moving across any land around her and making anything, and I mean anything disintegrate.
Now please review and tell me what you think...I know I need improvements...but the story will get better. Also, just so you know this story will somewhat follow the Naruto storyline.
!DISCLAIMER!
I do not own the Manga/Anime, Naruto. I do however own the exploding jutsu and Tora!
