Rise of the Chained Souls

Prologue

'Huh, where am I? What is this?' Thought a ten year old Naruto as he took in his surroundings. He appeared to be in a basement like room. The entire walls were rusty, there were no windows and it smelled of mildew. But what shocked Naruto the most was that he was strapped to a metal table. His wrist, legs, neck and waist securely fastened to the table making him unable to move. He also had a gag to muffle his voice. Seeing his position, Naruto started to panic.

The last he remembered, he was in his crummy apartment sleeping. How did he end up in this scary place and in such a terrifying position?

Before he could question himself more, he saw a dark haired man dressed in a plain black outfit. If the red, spinning eyes he had didn't Naruto, what he was pushing sure was. On the tray the new man was pushing there were many painful looking devices. There were needles, hooks, knives and even an electric saw.

Naruto started to panic, wondering what this man was going to do with all that equipment.

"Hehe, well, well. I see your finally awake, demon. Now, you can enjoy all that I will do to you. Hahaha."

Naruto was scared as he saw this crazed man laugh maniacally.

The man, seeing the fear in Naruto's eyes, grinned maliciously. "Oh, where are my manners. It is only polite for you to learn the name of your executioner. I am Sashiro Akukana and I will cleanse this village of your dark presence once and for all."

As the man brought his face closer, Naruto could see that what he thought were glowing red eyes was actually the Sharingan. Sashiro, seeing his captured victim's recognition, said. "Yes, you fear my eyes don't you. Good, you should fear my eyes. They were given to me by Danzo-sama specifically to destroy you. You see, I am going to put a Genjutsu on you. This Genjutsu will slow your perception so that every second feels like an hour. When I'm through with you, you won't even remember your own name. Hahaha."

Naruto could only stare in horror as the man picked up a knife from the table and approached him.

As the Akukana brought the knife down, he couldn't help but laugh as he heard the demon scream in pain and agony. The torture went on for 18 hours, meaning Naruto felt like he was tortured through 2700 days, around 7 years. Sashiro would always make sure Naruto was conscious for the entire process and gave him an IV so he wouldn't faint of hunger.

Naruto, although young, had a powerful mind because of the constant abuse. So, while his body felt the pain, his mind endured it. However, not even he could resist for so long, so eventually, he snapped.

Naruto's yell of pain suddenly become a roar of rage. Sashiro, startled by this, back away as he saw red, crimson chakra rush out of the boy's body, burning his bindings. The chakra continued to escape, fulled by Naruto's rage.

As Naruto, infused with Kyuubi's malevolent chakra, was overcome by madness, the Akukana tormentor was pushed into the wall. With horror, the fallen Akukana watched as the very air started vibrating, disrupting the atmosphere. What he didn't know was that he has disrupted the very barrier that held the dark creatures known as Heartless away. Where previously the immense amount of natural energy of the Shinobi world kept the Heartless at bay, the immense amount of malice being release because of the Kyuubi's vile chakra clashing with his container's psychotic breakdown started attracting the Heartless.

As the Akukana fled the room, he they didn't notice the dark tear in space as the Heartless came pouring through a corridor of darkness right upon Naruto. Hundreds upon hundreds of them started piling upon Naruto. Eyes glowing an eerie yellow, bodies the colour of shadows and claws blazing, they started clawing into Naruto, hoping to tear out his heart.

As they started clawing into his flesh, Naruto's seal reacted to their dark presence and, sensing it as Kyuubi trying to escape, started imprisoning the darkness accumulating around the Jinchuurikis. In a manner of second, the entire army of dark beings were imprisoned within the Kyuubi's Seal.

The Kyuubi jolted awake as it sensed the seal reacting to some form of energy. Suddenly, the sewer-like seal started rumbling. The water started rising and what appeared to be a black wave was heading towards Kyuubi's prison.

"Mmm, what is this?" Kyuubi said, eyes wide open as the massing black energy came rushing towards him. As the wave of Heartless hit the cage, the bars started eroding and the sewer started crumbling.

"Impossible, what manner of power is this. They are able to corrupt the seal. Can it be? Am I finally going to be free? Hahaha" The Kyuubi shouted with glee, but his joy was short lived, because as soon as the wave of darkness finished eroding the cage, it heading towards the bijuu. It size so massive it dwarfed the Nine Tailed Fox. It started coming down upon the energy being.

As the two masses of energy beings collided, the Heartless started slowing devouring the beast. However, the Bijuu chakra was also burning away the Heartless. Slowly, but surely, the two opposing forces started warring, blending, and mutating.

What was once the most powerful Bijuu of the time started breaking down into millions of foxes, each being the product of the million of Heartless that had been introduced to the seal. The foxes all had a melting black coat, with blood crimson tainting their paws and tails. Their eyes were bright crimson, filled with malice.

As this was going on, two souls who were sealed within Naruto the day of his birth started running towards the massive carnage. One male, tall, blond, blue eyed, wearing a white coat with flames licking the bottom. The other was female, a little on the short side, crimson hair, violet eyes, wearing an apron and a blue dress.

"MINATO, WHAT'S HAPPENNING?" Kushina shouted as she witnessed something she never thought she would see: The destruction of the Kyuubi.

"I don't know Kushina. It looks like something is destroying the Kyuubi. But that's impossible the Kyuubi is the most powerful force on the planet." Minato remarked more calmly than his wife. But, he too was flabbergasted by what he was seeing.

Suddenly, a dozen of the millions of mutated Heartless started flying towards the couple. Alarmed, they started running away, making sure they were not caught by this new threat. However, the foxes were faster and caught Naruto's parents.

Minato watched in horror as they dragged his wife into the giant mass as some started to devour him. They started tearing into his simulated flesh and blood started pouring into the sewer. Soon, his body was completely consumed. All that remained was a glowing ball of light, which was quickly devoured by a fox. The fox started expanding, shifting to match the appearance of the recently consumed soul.

The man once known as Minato Namikaze, Konoha's Golden Hokage and father to Naruto Uzumaki became the first artificial Akutama and the first of Naruto's vast army.
