Okay first things first I DO NOT SPEAK JAPANESE so for 99% of techniques I will be using english versions with the exception of the elemental names. I will also use the names like Konoha and Kiri to name the villages. Finally I will attempt to use the honorifics correctly but if I use some of them wrong please forgive me. Alright next there will most likely be Sasuke bashing because he is a jerk and Sakura bashing because she is useless until Shippuden. This is also a smart Naruto fic maybe dark Naruto it just depends on how the story goes. One other thing this is AU because while I know the basics of the sage of six paths and Kaguya along with the Juubi I do not know enough I feel to write that so basically what I am saying is to a certain degree and definitely later on say goodbye to cannon, not to say that the Fourth Great Ninja War won't happen but it will be different. This goes for pairings as well I personally do not care but may try to write them if I do there is a strong chance for Naruharem and OCharem but no more than four each. Finally both my OC and Naruto are going to be overpowered yes but it will not happen all at once I will try to make It rational but I am still new to writing so please bear with me ;however I do like godlike Naruto and my OC is going to need to keep up so if they become to overpowered to quickly that is the excuse I am going to use. DISCLAIMER: I do not own Naruto if I did there would not be so much filler.

"Hokage-sama we just received word the Kyuubi is on a rampage and it's on its way to the village" Reports a frightened ANBU as he appears before Namikaze Minato Yondaime Hokage of Konohagakure. Just as he is about to answer the ninja another ANBU arrives with more disturbing news "Hokage-sama another beast has joined the Kyuubi. It is the great demon dragon king of all demons."

A male Jonin came into the room and heard the last ANBU's report shock evident in his voice he exclaims "Minato-san I will go and hold them off for as long as I can hopefully you and Sandaime-sama can come up with a more permanent solution, I can only give you at most five hours most likely less. Also I came to tell you Kagero and Kushina each gave birth to a healthy son."

Worry on his face Minato says to the Jonin "Saizo-san don't we can find another way go to your wife and son." Turning around Saizo replies "I am sorry Minato but the village needs you more than me besides I am the only one who can use the barrier seal required to temporarily stop them with three of you otherwise occupied. So please tell Kagero that I love her and that I am sorry that I couldn't see our son grow up."

With those last words Saizo leaves. Taking a second to compose himself he turns to the ANBU agents in front of him and says "One of you go to Sandaime-sama and tell him to meet me in the hospital the other go and tell the ninja to evacuate the village we don't have long."

With a nod the ANBU members leave to carry out their tasks. Once they leave Minato goes to the hospital and accesses a certain room in the basement that has a very strong genjutsu on it. Once he enters he sees Sarutobi Hiruzen former Sandaime Hokage of Konohagakure and a trusted high ranking doctor by the name of Takayuki Kirishima.

As soon as Minato enters everyone looks slightly confused and worried and Hiruzen asks the question on everyone's mind "Minato-san where is Saizo-san?" Unshed tears in his eyes he turns to Kagero and answers "He went to place the barrier seal to stop the Rampaging Kyuubi and Demon King. I told him to stay but he was the only one who could do it because I am needed and you two just gave birth. Kagero-san he said he loves you and is sorry that he cannot see his son."

Tears flowing for the friend and loved one they all take a minute to compose themselves once they do Minato speaks "As much as I would like to mourn the loss of a former teammate and dear friend we cannot let his sacrifice be in vain we need a plan. There is one the one last resort plan that we all know but hope to never use due to it's drawbacks but unless we can figure out another one by the time the demons get here we will have no other choice."

Grim looks on all of their faces they begin to brainstorm but after four hours they came up with nothing. Just as the four hour mark hit one of the ANBU who new about the room burst in and exclaimed "The barrier that Saizo-san erected just shattered both demons are now only a few minutes out!"

With a heavy heart Minato turns to Hiruzen and says "Get the ninja ready to hold off the demons I need to go prepare the sealing I will join you as soon as possible." With a nod Hiruzen leaves with the ANBU while Minato along with Kushina and Kagero leave with the two infants to a secure location far from the village and start preparing for the sealing.

Just as preparations are complete a masked man wearing a black hooded cloak appeared "Well well well what do we have here planning to seal the demons away are you well that just won't do this village will die this night." With those words while everyone is still surprised by his appearance he throws a kunai knife at each child.

Just before the knives hit Kagero and Kushina jump in front of them to shield the children and are both hit with the knives. Meanwhile Minato engages the masked man and manages to catch him by surprise with a rasengan from above slamming the man into the ground but not killing him.

After the man gets up Minato asks "Who are you and why are you doing this?!" While holding his left arm the man replies "I am Madara Uchiha and as to why that should be self explanatory you may have won today but mark my words this village will fall."

With those words the man vanishes into a vortex leaving no trace he was there. As soon as the man leaves he turns to the two women and seeing both are severely injured he rushes to them. Once there he takes Kushina in his arms crying as he whispers "No no no no please don't die Kushina you need to live to take care of Naruto please don't go."

With a small smile on her face she replies " Don't worry Minato, Naruto will be fine without us now go save the village dear my time is up and I love both you and Naruto don't forget that." With those words Kushina Uzumaki passed from the world of the living.

Tears flowing down his face he turns to Kagero and sees that while very injured she still can move. Noticing his look she says "Come on let's get going, now that Kushina and Saizo are dead you and I are the only ones who can perform the sealing of the demons and remember the Shinigami requires the users soul so it can only be done once per person."

With a heavy nod Minato helps Kagero up and gathers the boys. They use the Harashin to make it back to the village Minato finds Hiruzen and asks that the boys be treated as heroes for what they are about to do.

After passing the message Minato summons Gamabunta and leaves with Kagero and the boys once in front of the demons both Minato and Kagero summon the shinigami and seal the two most powerful demons in the world into two newborn babies the Kyuubi was sealed into the son of Minato and Kushina he gained three whisker marks on each cheek he also had his father's bright spikey blond hair and piercing blue eyes.

While the other child received the demon king the Great Demon Dragon he was the son of Saizo and Kagero and had pitch black hair and dark brown eyes. After the demons were sealed away Hiruzen retrieved the children and headed to the council chambers after much discussion and arguing with the rest of the council both boys were placed in the same orphanage and given names.

Naruto was given the name of his mother and thus became Uzumaki Naruto the second child was given the name of his clan because he was the last member and due to the to the dark time for the village was given the name Yami and thus became Ryukasai Yami.
