Hello readers. (Sorry for the late update). Thanks for the awesome reviews. Let me start by clarifying some things.

There will be NO harem. I am thinking of writing a NarutoxNajenda Relationship, but its just an idea. Tell me if you guys want me to go in that direction.

As I said before OP Naruto won't be fighting too much, there will be some fights with Naruto in them (especially the one with Chelsea). I want both anime characters to have equal parts in the story. Naruto will be there but he won't steal the show.

Esdeaths sweet childhood that was systematically destroyed in front of her eyes is one of the main factors that I will use to turn her into a sadistic killer machine. It ties in to the story later on.

"I am Esdeath"

The stranger looked her in the eyes for a good 30 seconds. It made her fidget and a little self-conscious.

"No".

She looked at him in complete surprise at his short response.

"Excuse me?"

"I said no. That is not who you are."

"And how would you know, huh?"

The stranger looked at her with a looked at her with a deadpanned stare "Esdeath, really?"

She blushed a bright red at his statement.

Thankfully, he didn't question her about her identity anymore and they fell into an uncomfortable silence.

The silence was finally broken by Esdeath "Who are you anyway? and whats with the horns?"

The stranger was suddenly sporting a rather large smile. He went into a weird Kabuki stance with drums playing in the background, though who was playing them was a mystery.

"Who am I? I am the greatest man alive. Women swoon upon hearing my name. Men strive to emulate me. I am the strongest being in the universe. I am the one and only, Juubi." he finished while standing on foot and a sunset in the background, which should have been impossible considering they were in a closed room with no windows.

A cricket chirped nearby as Esdeath gave a deadpanned stare at the, now identified, Juubi.

"What a creep" she muttered under her breath.

"CREEP? I'll have you know that I am a very classy and handsome gentleman. People would kill to have my autograph."

He was now wearing a black tuxedo which made Esdeath wonder where he got it from and how did he change into it so fast.

"HOW THE HELL ARE YOU DOING THAT?" she yelled, referring to the drums, sunset in a room and now the sudden appearance of a tuxedo, which was now gone, by the way.

Naruto smirked "It's a secret".

Esdeath had multiple tick marks on her forehead as she gave him an annoyed look. 'I hate him' she thought. Her mood suddenly changed when she remembered what his name was.

"Wait, you are Juubi?"

"Yes, didn't you hear my awesome introduction? I worked for like an hour on that"

"Not really. Are you serio - what the hell?"

She was dumbfounded at what he was doing. Naruto was suddenly crouched in the corner of the room with his back facing her, rain clouds hovering over his head as he poked a stick at the ground

"So mean. i worked so hard on that introduction." she heard him say to himself.

"STOP IT" veins were starting to come out of her forehead.

"Are you seriously the Juubi? The one they said was a demon from hell, who's hair was said to be made up of black flames, the one with immeasurable power?"

"First of all, I ain't no demon and second of all, why would I have flames instead of hair. That sounds extremely painful" he had an annoyed look on his face as he replied.

"So you are the Juubi." She replied with barely concealed excitement in her eyes.

"As I said before, yes I am Juubi"

'This man is the best shot I have at getting my revenge on those bastards. Even if only half of what people say about him is true, it still makes him one of the most powerful individuals in the world.'

"Train me."

Naruto stared at Esdeath with wide eyes, taken aback with her sudden request. He suddenly schooled his features into a stoic mask and narrowed his eyes in suspicion.

"Why?"

"You don't know this, but those two guys that you killed, who were chasing me, they were part of a larger bandit group that attacked and plundered my village. They killed all the men and children. They put the women in cages like livestock. I may be little but I know what will happen to those women." Tears of anger and helplessness were freely falling as she looked Naruto right in the eyes.

Naruto stared at her face for a couple of seconds. 'No matter what era it is,there will always be scum somewhere.'

'Yes, but the more dangerous problem here is this girls desire for revenge. You remember how that turned out last time, right?' Kurama said.

Images of a certain black-haired avenger popped into Naruto's mind. 'Yeah, that was not pretty.'

'If you do decide to take her on as a student, you should know that she will become a very strong fighter when her training is over. Perhaps even one of the best in this world, excluding you.' Gyuki chimed in.

'I know that, but if I leave her rage unchecked she might end up doing something drastic, something from which there is no coming back. The best way to make sure that she stays safe is to keep an eye on her. Which I can do while training her. Maybe even help her get over this tragedy.'

"Fine, I will teach you." Esdeath breathed a little easier. "But I have one condition and it is non-negotiable."

"What is it?" Esdeath was determined to increase her power and she would do anything for it.

"You are forbidden from seeking revenge if you want to become my student. I want you to make this promise with me and yourself".

Esdeath's stomach dropped. 'He want's me to let those stains-on-humanity go? Is he crazy?'

"WHAT? You can't just expect me to let them go? You want me to just bury my anger? THEY TOOK EVERYTHING FROM ME. My mom, my dad, my home and you want to let them live? No, I will not acce-".

Esdeath was interrupted by Naruto "No. They will not live and I certainly know you won't just forget your anger, especially not after what they did to you. But as my master and my sibling disciple once taught me. Killing for revenge is never the answer. All it does is give birth to a new cycle of never-ending hatred. If there is such a thing as peace in this world we must seize it and break the curse of hatred that haunts this world."

Esdeath thought about what he said, 'Break the curse of hatred? A cycle of never-ending hatred?'. A series of images flashed through her mind. Images of her home burning, her father being struck down, her mother lying on the ground screaming for her to run.

'No. Those scumbags don't deserve any mercy. They need to die and I will make sure that their deaths are painful. but if I don't agree to his terms he may send me away. I need power right now.'

Naruto watched her face go through a myriad of expressions. Confusion, sadness, rage, greed before finally settling on a stoic mask.

"Fine, I agree"

Naruto didn't need to have the negative-emotion sensing ability to know that she was lying. But short of imprisoning her, training was the only real way to keep an eye on her and maybe try to help her.

"Okay. Since you're healed up, training begins tomorrow" and with that, he left.

(The Next Day)

Esdeath was sleeping peacefully in her bed. Blissfully unaware of what was about to happen to her.

"GOOD MORNING CHIBI."

Esdeath jumped 10 feet in to the air and landed on her head. Standing up she glared at the one who woke her up. Naruto stood in the doorway with a huge smile on his face.

"Tortu- Uuh, Training starts in 30 mins, outside. Breakfast is in the kitchen and that door to your right is the bathroom."

His look turned quite sadistic "Oh, and if you're late you'll be doing 50 suicide sprints around the training ground"

He then went back to his cheery self "see ya" with a final wave he turned back and disappeared down the hallway.

'I hate him. I will kill him. No, I will make him beg for death. I will torture him to death' Esdeath continued to imagine painful ways to kill Naruto as she brushed her teeth, took a shower and then went to find the kitchen among the maze of doors that lined the hallways. Some of the doors were locked while the rest looked like simple rooms.

'Bastard didn't even tell me where the kitchen was how am I supposed to find it in this cave?' After 10 mins of searching she finally found it.

It wasn't much. A stove rested on the side of the wall, opposite the door, with tables on both sides. There was a large cupboard attached to the left wall. A large table rested in the middle of the room and on it were a plate of eggs, bowl of rice and a glass of milk, her breakfast. All of which was now cold because the bastard couldn't be bothered to tell her where the kitchen was. After she was done with the breakfast she went in to the main hallway and started walking towards the light.

She arrived in the clearing where Juubi had found her. The remains of her pursuers had been cleared and all signs of struggle were removed, leaving the clearing as pristine as it was before her arrival.

In the middle of the clearing sat Juubi with his eyes closed, surrounded by animals of all sorts ranging from small birds to large deer. There was even a falcon resting on his shoulder. As soon as she came close, all the animals took off back into the woods.

Without opening his eyes Naruto said, "You're 10 mins late. You know what that means, right? 50 suicide sprints around this clearing."

Esdeath looked at her new sensei in disbelief. The clearing was surprisingly circular and had a radius of about 100 meters. 'Is he crazy? This is way too much. I can't run tha- wait a minute'

"This clearing wasn't this large when I arrived here". She eyed her surroundings suspiciously.

Naruto looked at her with a raised eyebrow. "Are you saying that I moved all the trees and the rocks and then regrew all the grass that would have been destroyed in the process?" 'Because that's exactly what I did. Thank you Mokuton'.

'Now that I think about it, that does sound kind of impossible. But he does have unlimited power, who knows what he is capable of. Wait, isn't he a being of death and destruction? Creating life should be impossible for him. Gaaahhh, this is driving me nuts'.

Internally, Naruto was laughing his ass off as his student tried to come up with a way to argue with what he said.

Esdeath finally gave up on trying to find out how the clearing got bigger and tried to reason with her crazy and sadistic sensei.

"I guess not."

"Okay, now let's get started on those sprints. We haven't got all day"

"Wait, 50 suicide sprints is wwaaayy too much and I'm late because you couldn't be bothered to tell me where the kitchen was. I had to walk around for 10 minutes trying to find where it was".

Naruto looked at her, confused "I didn't?"

"Thousands of years old and you're still as dumb as a bag of rocks". Kurama face palmed at his containers stupidity.

Matatabi decided to add in her two scents. "Even the intelligence of thousands of shinobi is insufficient to cure you of your dim wit."

9 voices laughing could be heard within Naruto's mind. 'Hey, I can be smart' was Naruto's intelligent reply.

At that moment a brilliant idea came to Naruto.

"Actually the reason for that is because finding breakfast was part of you sensory training. You were supposed to use your nose to find the food". Internally Naruto was thinking 'Hope she buys that crap.'

Even though Esdeath was only 8 years old, she knew the man before her was spouting complete bullshit to save face but she decided to let it go in the end, reasoning that this would make her stronger in the long run and so her training began with 50 suicide sprints and a completely bullshit sensory training story.

'Power above everything' became her new life motto.

Naruto came up with an intense training schedule for her. She would wake up at 6:30 and be done with her morning rituals and breakfast by 7:00 after which she would proceed to the clearing that was to be her training ground.

She would begin by running 10 laps around the field. After a 15 minute break she would have strength training. Since she was still a child the strength training was quite light and would mostly focus on her core. She would then run another 10 laps around the clearing.

After her laps they would stop for lunch. After lunch she would have to endure three hours of weapons training, the weapons would range from a small knife to a large halberd.

When she would be done with her weapons training she would get a half hour to relax and cool down. After the break she would learn different fighting styles and techniques. At this time the sun would start to go down so she would end her training by running another 10 laps.

Upon hearing this schedule she almost feinted right there.

"ARE YOU CRAZY? I CAN'T DO ALL THAT."

Naruto looked at her dead in the eye and with complete seriousness replied "I know. You can't possibly do all that but the point of setting such high goals is to train your will alongside your body. To be able to go on, even when your body is broken. That is what my training is all about."

Esdeath felt the respect for her white haired sensei go up a few notches. She looked at him with determination and said "Bring it on, I'm ready".

(Later that day)

"I hate you so much".

It was almost night time and Esdeath was lying on the ground with her arms and legs spread wide glaring at the smirking white haired figure looking at her from above. She had finally completed the days training but she hadn't been able to complete each part on account of her small stamina.

"Whatever happened to 'Bring it on, I'm ready'".

"My body hurts. Like everywhere."

Taking pity on his student, Naruto picked her up in a bridal carry and took her to her room where he gently set her down on the bed and said "Rest up now, You will need all the energy you can get for tomorrow."

and then he was gone.

'I need to do this if I want to get stronger. I will take everything bastard-sensei throws at me and become the strongest person in the world'. The days exhaustion finally took hold of her and she was out like a light.
