Chapter 1:

The Death of Number 1 Unpredictable Ninja and The Birth of The Most Powerful Magician

Prologue Begin! Drive Ignition!

Team 7 was in their mission to guard Tazuna, the bridge builder from Wave country. On their way to Wave country, team 7 was interrupted by the demon brother and the nuke-nin from mist, Momochi Zabuza, but the nuke-nin was forced to retreat and wounded by Hatake Kakashi, the copy-nin, team 7's sensei.

After a weeks,

Team 7 had trained to make their cakra control better for a week and they was in their final battle with Momochi Zabuza and Haku, his tool…

Sasuke was catch his self trapped in Haku's Demon Ice Mirrors. After he saw that, Naruto dashed inside the Demon Ice Mirrors to assist his teammate.

"Are you idiot or something? I can handle this alone." Sasuke said with his arrogance tone.

"Damn. I just come here to assist you, teme" spoke Naruto.

"Hnnn…" reply Sasuke, but in deep in his mind, he was relived there are someone come to assist him.

"I'll take that mean 'Let's go', I'll try to make a chance for you, teme" said Naruto with his foxy grid.

After said that, Naruto threw some of shuriken and he charged Haku. Naruto tried to make Haku out from his mirror, but his entire move was too slow in Haku's eye. While Naruto made Haku busy with his action Sasuke began to flare his chakra and made several hand seal to make Chidori (I'll make Sasuke had mastered his Chidori, because he has been trained under Kakashi's wing far before he graduated from academy [ONLY in my story off course!]). Haku sensed the flare of chakra and threw some of poisoned senbon needle to stop Sasuke action, but Naruto jumped in front of Sasuke and made his body as a shield to make Sasuke finished his Chidori and collapsed in front of Sasuke. Sasuke saw Naruto sacrifice and he would not waste his teammate sacrifice and land Chidori in Haku chest. The Chidori made Haku died instantly. After land his strike, Sasuke dashed to Naruto and checked his pulse, Naruto was still alive, but he knows his teammate in crisis condition.

In the other place of the bridge, Kakashi won his battle with Zabuza. He sensed Naruto's chakra signature weakened and he quickly runs to Naruto's location to check his condition. He saw Sasuke and Sakura tried to make Naruto still alive with some basic medic.

"Why? Why you make yourself as my shield? You wanted to be Hokage, right? And you just throw that dream only to save me…"spoke Sasuke quietly.

Naruto coughed and with his heavy breath, he spoke "Hehe… I…can't… to*cough*be…..a Hokage… if...*cough*...I let….my teammate died in front my eye... *cough*" Naruto knew he was in the end of his life and he spoke his dying massage to his Team

"I…wish…you…to success…revive*cough*your... *cough*clan…and don't... Let*cough*...Your anger… make you... walk in wrong way…" Sasuke just simply nodded with sad eye

"Sakura…I want you….to take my place…to assist and help Sasuke…*cough**cough*...And I... sure you'll…be a great kunoichi…someday…" Sakura was tried to held her tears but failed, she cried for her fallen teammate

"and…*cough*Kakashi… Sensei…I'm sorry…I... Can't*cough*to be…your best… student… and..I want you…. To give my thanks to…*cough* Sarutobi-ojisan for…being my…grandfather….."

"You're made me proud and you're one of my best students, Naruto... I'll send your word to Hokage-sama…" reply Kakashi with teary eye.

"Hehehe….I…happy…was hearing…that… Arigato…. Kakashi-sensei, Sakura… And Sasuke for being… my teammate and my sensei…" said Naruto with his last foxy grid and he slowly close his blue-sky eyes.

That day was the darkest day. One of the most promise ninja, the number one unpredictable ninja, closed his eyes from the world and never open his eyes again.

At the Kyuubi's dark catacombs, inside Naruto's mind...

Naruto found himself in front of the Kyuubi's cage. Kyuubi annoyed after saw her container most stupid action. (I make Kyuubi is a female, I always love seeing kyuubi as a beautiful woman with fox ears and nine tail in her tail bone)

"SO IS THIS THE END OF YOUR LIFE, MORTAL" scout Kyuubi wth heavy voice.

"Urusai (Shut up), baka kitsune (Stupid fox). I've no regret if I lost my life for protecting someone precious to me, Sasuke is my first man I finally can called best friend," said Naruto. His eyes show how deep his determination.

'Hnn... He most likely his stupid father, the Yondaime, who died for protecting his precious village' think Kyuubi. She smiled proudly how his container had become a man like his father.

"Is there something in my face?" asked Naruto innocently.

"Hah? Iie, kinishinaide (do not mention it), Mortal. What do you want to do now, you just have throw your life for your selfish 'protecting something or someone precious to you' " mocking Kyuubi.

"Hnn... I do not know… I always wanted my name craved as a hero of Konoha, but most likely the villager happy after hear my death… They always saw me as a 'demon brat' not as 'a hero that keeps sealed the great kyuubi no youko for them'…. I always wanted to have different life that many people love me like a family"

Naruto voice became low" Now…. I can free from this suck life…., I'm sorry for take you with me….I'm so sorry, Kyuubi. I wish I can free you from that cage before I truly die, but I'm sorry I can't do anything about that seal," said Naruto "For now, let me rest… " after said that he close his eyes and his body began to fade.

Kyuubi changed herself into her human form and hug Naruto as Mother hugs her child, the great Kyuubi no Youko cried for her container.

'I am so sorry too, my little kit. I've make your life like a hell that no one acknowledge you' she looked Naruto with sad eye 'There is a way to make you live in different life, I'll merge your soul with mine to give you second chance of life'

Kyuubi raised her tail and spoke with demon language to start the ritual suddenly the room had become bright. The light swallowed Naruto and Kyuubi transport them from the dark catacomb to unknown world and make their soul become one.

Prologue Ended! Prepare for the real story…! Stand By Ready!

"Ruuna-Chan, wake up!"

A little girl around 10 years old open her eyes slowly, her eyes have 2 different colors for each eye. The blue sky color is in her right eye and red blood color in her another eye and she has long golden hair and three pair 'whiskers' mark in each of her cheek. She slowly, rubs her eye, sees a woman with golden long hair, and has a pair of red color eyes. She was Mikazuto Ruuna (She was Naruto and Kyuubi reincarnation)

"It has 07.00 am; you must go to training ground for your magic test right? Nanoha and Vivio have already leaved 15 minutes ago," said the woman with soft voice.

"Heee… Fate-Mama, I really overslept. I must hurry, I don't want Nanoha-Mama and Vivio-Oneechan angry for my late" as she said that, she jump from her bed and quickly run to bathroom to wash her face.

The woman who called 'Fate-Mama' was Fate Testarossa Harlaown, she is captain of Lightning Squadron in 6th Mobile Division. Ruuna called her 'Mama' because Fate has taken care of her since she was found by 6th Mobile Division in an ancient ruin 5 years ago. Fate was trained Ruuna how to use close range type device like her device, Bardiche (a close type device with death scythe form).

Once Ruuna finish washed her face, she quickly changed her clothes with her white T-shirt and blue navy long pants. While she change her clothes, Fate help to brush her long golden hair and make a high ponytail (Ruuna's hair was reached her leg and when her hair in high ponytail it looks like Signum's hair style in the anime but with golden hair not pink color hair).

"I'll pass the test and make you proud, Fate-Mama," said Ruuna clearly with her best smile.

"I know you'll pass the test, Ruuna-Chan" reply her step mother "now I'll accompany you to training ground" She said with her soft smile.

"Arigato, Fate-Mama" Ruuna is very happy hear her stepmother will accompany her to her magic test and hug her mother.

After a couple minutes

Ruuna with her stepmother arrive in 6th Mobile Division training ground. There are Nanoha, Vivio and Hayate wait for her arrival to give her test. Nanoha who Ruuna call 'Nanoha-Mama' is Takamachi Nanoha, the captain of Star Squadron in 6th Mobile Division. She is Fate's guardian, so she can be calling as Ruuna's Godmother. Nanoha has purple color eyes and light brown long hair with side ponytail. She was trained Ruuna for long-range combat and how to use long range type magic like her speciality.

She smiled when she saw Ruuna and Fate arrived in training ground. In Nanoha left side, there is a girl around 14 years old with long golden hair and have same eyes like Ruuna but she has green color in her right eye not blue sky color. She is Nanoha's stepdaughter, Takamachi Vivio. She is a member number five in Star Squadron. She is like Ruuna older sister, she has help Ruuna in her hand-to-hand combat training.

Moreover, the last is Yagami Hayate, she is the chief of 6th Mobile Division, she has deep blue color eyes and short dark brown hair. She had trained Ruuna for her elemental magic training.

Fate, Nanoha, Vivio and Hayate with all member of 6th Mobile Division had trained Ruuna for last five years since they found her in an ancient ruin.

Flashback Begin!

5 years ago, the 6th Mobile Division was detected an extremely large magic source in an ancient ruin. Fate Testarossa Harlaown and Takamachi Nanoha were sent to that ancient ruin to investigate that magic source. In that ruin, they found the source magic in the deep of the ruin. The source was a naked 5 years old girl with three line mark in her each cheek in the middle of an unknown magic circle, she was in unconscious state. They made a decision to take her to 6th Mobile Division for her medic treatment and to investigate her when she regained her conscious.

The girl was regained he conscious and slowly open her eyes. She saw an unknown place with white ceiling and three women with a 9 years old girl sat on sofa in right side from her bed.

"Ah, you're finally awake, little girl." Said Hayate with her soft voice while Nanoha and Fate helped the girl sat in her bed.

"Where am I? And who are you?" asked the 5 years old girl.

Nanoha began to talk as Hayate's replacement to explain the situation

"You are in 6th Mobile Division's treatment center. My name is Takamachi Nanoha" and she was pointed to the others"with the long hair is Fate Testarossa Harlaown and the girl is my daughter, Vivio. The last is our 6th Mobile Division Chief, Yagami Hayate. We found you in the ancient ruin. Would you mind to tell us how you was in the deep part of that ruin?" spoke Nanoha.

"I… don't know….and I can't remember what happen to me" reply the girl with her face looked down.

"Well then, can you tell us where is your parents now?" Fate gave her next question.

"I*sob*… can't remember who my parent is*sob*… I only remember my name" the girl started to cry.

"Please don't cry, little girl" said Fate, she tried to comfort her and asked, "Would you tell me your name?"

"Ruuna… Mikazuto Ruuna. That's only I can remember…" Ruuna said, she was tried to not cry.

"Okay, Ruuna-Chan. Until you receive your lost memory or we find your real family, how about we take care of you and do some magical training to control your magic?" smiled Hayate.

"Take care…of me…. Like a family?" Ruuna chocked, she only understand that she would have a new family, but she wasn't have no idea about magic stuff..

"Yes. You can call there of us 'Mama' and Vivio as your Oneesan (Old sister), if you want" reply Nanoha.

Ruuna was shocked but in the deep of her mind, she was very happy heard that she began to speak with her cheerful voice.

"Fate-Mama… " and Fate replied "Yes, Ruuna-Chan?" and Ruuna changed her look to Nanoha "Nanoha-Mama…" "Hai, Ruuna-Chan?" reply Nanoha and Ruuna turned to Hayate "Hayate-Mama" Hayate smiled and reply "Hai, little angel?" last she turned to Vivio "Vivio-Oneechan…" Vivio smiled and spoke with cheerful voice "What do you need, Imouto (Younger sister)?" Ruuna started to hug each of her new 'Mama' and her new sister.

Flashback Ended!

"There you are. We had waited you; let's start your test, Ruuna-Chan" Hayate smile to Ruuna.

"Hai, Hayate-Mama. I'm ready!" reply Ruuna

(AN: Let us skip her test)

On the next day, Ruuna wake up at 07.00 am sharp and take shower, she has to meet all of her 'Mama' and her Sister to give her the result of her test. She wears her 6th Mobile Division uniform that Fate gave yesterday. After that, she quickly goes to 6th Mobile Division's Lobby where her 'Mama' and Sister wait her.

In 6th Mobile Division Lobby

Ruuna find them sit in sofa and when they see her, she quickly give them a salute and speak with clear voice "Mikazuto Ruuna, 6th Mobile Division's Private Military Trainee. Has come here to take the result of my last magical test"

"Ara, Ruuna-Chan. You don't need to be formal like that" Fate gives her a smile.

"The he... I'm sorry, Fate-Mama" Ruuna smile while scratching her cheek with her little finger.

"Let's talk about the result of your examination" smile Nanoha "Ruuna-Chan, you have no problem with your technique, but you have learn more how to control your power. Remember how much damage you caused in your test yesterday, you near destroyed whole training ground" Ruuna slightly blush after hear that. When the other saw her blushed and they scouted in their mind

'KAWAII!!!!'

"And..." Hayate begin to speak with serious tone "we'll give you three stages ability limiter to help you control your magic power, you can remove them if you want, but it'll give more stress to your body if you overpower yourself, because your body is not ready to handle your massive magical power"

"I understand, Hayate-Mama" reply Ruuna

"Don't worry about your ability limiter" interrupt Vivio and explain "with your stage 1 limiter, you are already an S rank mage and when you release all of your limiter you will be SSS rank mage, in the other word if you release your limiter, you're the most powerful mage in the world that surpass all of us in here"

"And last, you'll be place in my Squadron, The Lightning Squadron, as member number five, because you have not enough experience in the real mission, you've to learn about real mission step by step" Fate smile to her and give her a hug.

"But before that…" speak Nanoha "I believe Hayate-Mama has something for you as a present for your pass"

"When we found you in ancient ruin 5 years ago, we also found this bracelet. We believed this was yours, but we didn't know how to active that device" speak Hayate while she open a chest, and give Ruuna a beautiful golden nine tail carve bracelet with a red blood color and blue color slit gem like a feral eye (the gem is like dragoon spirit in game Legend of Dragoon) attach in that bracelet.

When Ruuna hold that bracelet, she shocked for some strange vision suddenly fills her head.

"What's wrong?" asked Fate worriedly.

"I think I remember something with this bracelet," said Ruuna and Nanoha speak to her "Let's go to training ground to active your device; I believe we can't do that in here"

"I agree," replied Hayate.

In training ground

"Now you can active your device and spell the activation spell" smiled Fate.

"Hai, Fate-Mama" replied Ruuna and she begin her device's activation spell

"I, Mikazuto Ruuna, who have accepted to hold the ancient magic, I call you forth to make an ancient magic contract, and l need you to release your power. Wind in the sky... Stars in the heavens... And a never-ending will of fire within my soul! Magic within this hand, I command you the ancient device, which can bring down the eternal flame from heavens, Blazing Kaizer, drive…"

and the bracelet respond and some mechanical voice speak "IGNITION"as a huge bright beam of light pierce the sky and bring down a blaze of red and blue flame from the sky. The flame makes a magic circle when it reaches ground (Like Phoenix summoning in Final Fantasy VIII) and some of ancient language heard from the device. Next, the bracelet responded and speaks again

"Stand By, Ready! Set Up!!"

After that device spoke, the bracelet becomes shine brightly. And Fate shout to Ruuna

"THINK ABOUT FORM OF YOUR STAFF AND A BATTLE GEAR WHICH CAN PROTECT YOU BODY!" she has to shout because. A gust of wind with noisy sound is surrounds Ruuna.

Ruuna give a nod and close her eyes to think what form of her device will take, the bracelet become change its form and make a staff like Fate's Bardiche Assault (like in its anime, with a revolver type cartridge system of course) but it has golden color with red crimson color in its grip.

"Barrier Jacket, Striker Form"

as it say that Ruuna's clothes change, her clothes become like Fate's Barrier Jacket, but it has blue color basic of her clothes include a pair of glove which it has golden plate arm protector (Like Saber's glove in Fate Stay Night) and a pair of golden greaves in her legs. A white cape with red crimson fire like Yondaime's Hokage cape covered her back. After the transformation end, Ruuna see her new combat gears and jump happily

"Yayy!!! I have barrier jacket and my device form like Fate-Mama"

Anyone hear her sweat drop and think 'The reason you have device and barrier jacket like Fate is you only thinking about Fate when you make your own form of device and barrier jacket' but they proud to see their apprentice has become a great mage.

A month after that…

6th Mobile Division detects an abnormal and unknown portal at the ancient ruin where Ruuna was found 5 years ago.

"Let's investigate that ruin again, most likely there was a lot of Lost Logia lost in there" said Hayate and ask to Shari, her assistant "Who is the agent that free for now?"

"There is one agent available. She is Lightning Five, Mikazuto Ruuna, she is on her way back from her previous mission" replied Shari

Mean awhile

Ruuna just arrived in 6th Mobile Division's base. She hears one of her 'Mama' speak to her with telepathy.

'Ruuna-Chan, are you hear me?' Hayate ask to her via telepathy.

'Yes, loud and clear, Hayate-Mama' replied Ruuna

'Good. I'm sorry you just arrived from your mission, but there is some unknown portal in the ancient ruin that we found you 5 years ago, we believe some of Lost Logia had lost absorbed by that portal . I want you to investigate inside that portal, it can be dangerous to send you there, but we don't have any our best mage free from now. Only you are free from now' Hayate is little worried to send a 10 years old girl for dangerous mission like that.

'Don't worry about me, Hayate-Mama. Because I'm a girl who can make impossible possible' replied Ruuna with cheerful voice.

'I glad you said that, but I want you have prepared for the worst scenario, because we don't know what is exactly happen in there. There is a strong magic field that block our scanner' Hayate seriously and Ruuna reply 'I understand' as she said that she run to 6th Mobile Division garden

"Blazing Kaizer…," said Ruuna

"Yes, My Master" respond the device

"Can you set up for me now?" asked Ruuna

"It's Clear To Go. Stand By Ready! Set Up!!"

As Blazing Kaizer said that, Ruuna's body engulfed with red crimson and blue color fire. After that, her clothes changed to her battle gears and Blazing Kaizer said "Arc Wing", suddenly three pair of beautiful wings appears in her back and she flies with high speed to her destination.

"Lightning Five, Mikazuto Ruuna, Begin the mission!" shout Ruuna and she flies with lightning speed.

After 5 minutes fly with her high speed, Ruuna begins to see her destination. She slowly land in front of the main entrance of the ancient ruin, she enter the ruin and she makes some light sphere that preceded her and enter the ruin first (the light sphere is W.A.S or Wide Area Search like in Mahou Shoujo Lyrical Nanoha anime). In a couple minutes, her device responds.

"Wide Area Search Successful. Coordinates Are Specific. Distance Calculated. Master, You Can Reach The Target In 1 Minute 20 Second." Speak Blazing Kaizer.

"Roger that. Lead the way, Blazing Kaizer" reply Ruuna happily.

"Yes, My Master" respond Blazing Kaizer

When she reaches the portal, she sees a large scale of portal. That portal is unstable and it starts to self-destruct.

"Woaa… This is bad, REALLY BAD" shouted Ruuna.

She knows she has to leave that place, but it is too late. The gate began to swallow anything. She can only make a protection for her body with her device.

"Protection Flame"

And red and blue fire warped Ruuna's body to give her protection. Her body swallows into that portal and brings her to unknown world.

To Be Continuing…

AN: Whew… Chapter 1 had finally done. I gave all of my best to make this chapter become easy to read because of my lack of English grammar. For the name of our little hero in this fanfiction, Mikazuto Ruuna, it is an anagram from Uzumaki Naruto (I only change Uzumaki Naruto word order, and I find the name Mikazuto Ruuna accidentally). In the next chapter, I plan to bring her back to Konoha, but she does not know Konoha because her amnesia. So I write it as unknown world in this chapter. For the Kyuubi, I will make her as other Ruuna. Other Ruuna is another Ruuna's personalities like Kyo and Kyoshiro in Samurai Deeper Kyo (I think it is will be good if our little hero has two personalities), I will reveal her split personalities in the next chapter. You can also give me some of your idea for this fanfiction. So please Review. THX.
