A/N this is my first fanfic ever, so please excuse any mistakes I make. The inspiration behind this is reading all of those fics with Naruto having a form of sword so I decided to give him a little change

Disclaimer: I do not own Naruto

The Shinigami after a long day of taking souls, had just sat down. Then he received a warning from the mortal realm telling him that he was being summoned.
"Damn humans, always need someone else to do their dirty work." He grumbled.

Before he left, he took one look at his son and sighed, he had no control of stopping this summon and he didn't have time to get someone to look after him. So he scooped the little boy up and strapped the baby to his front. The Shinigami then stepped through the portal and entered the mortals realm.

"Damn it, the Kyuubi cannot be sealed in me, it must be a child" Thought the Yondaime Hokage "My plan is ruined, but I will push on, once the Shinigami has been summoned my life will be taken anyway. I will just have to hope luck is on my side tonight."

From a-top a huge toad, a man with yellow hair stood, with his hands in a seal. Disappearing in a yellow flash, he appeared upon the demon who was attacking his homeland. Grabbing on with all his strength he let the Shinigami do his thing by pulling out the Kyuubi's soul.

After pulling out the Kyuubi's soul, it's body vanished and the blonde haired man fell, making no attempt to break his fall.

Standing back from all the commotion the Shinigami was furious. The summoner's body was not able to handle the excess of chakra given by the Kyuubi. If he allowed him to enter the spirit world with him inside, he had no idea how bad this could turn out. From the implosion of his realm to all of his damned spirits escaping. He had little time before he dragged the spirits back, the Shinigami had one option....

He held his son in front of him, now crying from all of the action. The Shinigami thrust the Kyuubi into the baby and sealed it in. Tears welled up in the babies eyes after having stopped the moment before the sealing, and the the baby fell asleep. The Shinigami had to stop him from crying as the only thing he loved was being sacrificed because of the humans mistakes. The Shinigami knew he couldn't stay with his son in the realm, as the powers which even he couldn't challenge, ruled that when a god has sealed something into a human, he must deal with the summoner in the god's own realm.

So before leaving the Shinigami shrank himself to human size and appeared at the Hokage's office. There he left his son and a note. Sensing others were approaching he kissed his son on the forehead and stepped through the portal back to his own realm.

The Hokage was not in a good mood. The fourth Hokage was dead leaving him to do mountains of paper work, but he was mainly unhappy about all the deaths caused by the demon.

He took one more step and entered the office, there he was shocked at what he found. A little baby boy fast asleep on his desk. He rushed over and found the note laying on top of the baby.

Dear Saindame Hokage,

The Yondaime Hokage summoned me, the Shinigami to help deal with the Kyuubi threat. However he did not know that a demon can only be sealed within a child as their chakra coils will later develop to accommodate its chakra. Luckily I brought my baby boy with me, who had only just been born on this day. I sealed the Kyuubi within my son and I leave him in your care. I can no longer care for him in my realm as it would be ripped apart by the Kyuubi's presence. I ask you to help my son train to be a ninja, as when he comes to the age of 12, will gain a kekkai genkai and will be trained by me to become a Shinigami. Also my son will also resemble the summoner who summoned me. My son probably will not be able to be entirely cared for but at least show him some love and attention and keep him alive.

Yours faithfully

the Shinigami

The Hokage finished reading the note and to say he was surprised was an understatement. He knew this was going to be a lot of trouble but he respected the Shinigami for making such a sacrifice. He began making arrangements for the boy's future as he knew he must act quickly before questions were asked. The Hokage then realised something, this boy had no name. Thinking of suitable names for the child and picked the name that the Yondaime would have called his baby boy if he had survived; Naruto.

For now the Hokage decided to put him into an orphanage, for how long that would last he was unsure.

Whilst the Saindame was busy setting up Naruto's life, several members on the council had entered his office. As the Hokage was not there at the moment, they were a little bored to say the least. One of them had picked up the letter laying open on the Hokage's desk and had read it. He quickly yelled at the other members of the council and told them what had happened, they all ran out to find the boy, and to kill him.

They found the Hokage walking with the baby in his arms. They all ran at him and started yelling things at him.

"HOW COULD YOU LET THAT DEMON LIVE!?!?!?"

"KILL HIM!"

Several ANBU appeared ready to fight but the Hokage waved them off.

"I want none of you to ever talk about this again, EVER!!!! Do you understand? I decree that anyone found passing on this information, will be killed on sight." The Hokage was seething, he had never wanted this to happen. He wanted the Shinigami's and Naruto's sacrifice not to go unrewarded. Now the secret was out, it will make his job at protecting the boy so much harder.

He then hurried off with his escort, to prevent any further outbursts. Giving the boy to the orphanage owner, he then left to deal with the destruction caused by the Kyuubi. He hated paper work.

A/N - I hope this was good enough, even though this is just the prologue i don't want it to be a half job. Please review and give me any advice on writing tips and even ideas on Naruto's kekkai genkai.
