Author notes- I was looking through the fanfiction stories and kinda noticed that there are no crossovers that have naruto housing either Diablo or tyrael from the Diablo series so I decided to start my works over again except for potv and focus on the three. The Diablo/naruto works are brother/sister fics and if anyone wants to use the idea then simply pm me with your idea and I'll look after it. As for pairings the Diablo one will have a small harem while the tyrael one is a single pairing.

-I claim no ownership of either Diablo or naruto. I do however claim this story as it with the exception of the characters is my own idea with a few similar plot points.

The God of Shadows Reborn

October 10th, Night of the kyuubi's attack-

All was silent in the Elemental countries as the sun had fallen and almost all of the world was sleeping preparing for the next day of their lives. However in Hi No Kuni there was a loud roar as a monster attacked the Konohagakure in the dead of night. That monster was the legendary Kyuubi no Kitsune a monstrous nine tailed fox that could level mountains and cause tsunamis with its tails. The village's defenders were fighting trying to hold back its rampage from reaching their home but alas they were not strong enough to push the fox back as it was too strong for any human to fight head on. The best of the village was fighting it but one face was missing from the defensive line. Their leader Minato Namikaze was not fighting the fox but rather the one who was controlling the fox sending it on its attack. That night his wife, Kushina Uzumaki, was giving birth to his son, who would be called Naruto, when they were attacked by a strange masked man. The only part of his face that was visible was a single eye that reflected hatred, envy, and lust within it. The man fought Minato and was able to remove the Kyuubi from Kushina who was weak from childbirth. The Kyuubi tried to fight back from its influence but it was too weak from being sealed for so long inside of the Uzumaki and could not escape or resist its eyes influence. It was then sent to fight and destroy Konoha as a form of revenge by the masked man.

Kyuubi POV-

The kyuubi even though it was destroying the village and its defenders was ashamed as he couldn't free his body from that man's control and was obeying his will. It was always a prideful creature but it cursed being weak even now. The defenders were fighting as hard as they could to push it back and it was impressed by their resolve and their skill at their attempts. It brought to mind that last battles he fought in before he entered this world. It brought back memories of before he was known as the Kyuubi and he was called the Lord of Terror. He was known as Diablo one of Lucifer's sons and the greatest leader of hell's armies. He had entered this world after his defeat at the hands of Tyrael, the archangel, and the humans of sanctuary who fought him in the shining heavens. When he entered this new world he changed his form to hide from Tyrael and the angels to get back to full power. He had made a trip back to hell and absorbed the essences of both Lilith and Rakanoth in order to repair the damage and grow stronger in order to not be beaten again. When he entered the new world again he continued trying to gain a foothold in the mortal plane.

He then remembered his greatest humiliation as he was defeated by a single human monk who had powers that he had never expected. He was then sealed within his body by a seal powered by the gods themselves. He experienced many things with the monk who would later be known as the Rikudo Sennin, the founder of the ninja system, and was changed by the man. Where he once was focused on death, conquest, and destruction he slowly lost interest in waging war and battle. The man actually influenced him and started to redeem Diablo and he was surprisingly thankful for it. The evils within him also grew to respect him and when it came for him to set us free he decided to split us to give us our own individuality back. He then asked us to watch over the world and prevent it from destroying itself from within and without. Our body was sealed within the moon and our powers and spirits were split to our respective beings. We then decided to try to stop our never ending war with the angels by having all our forces and our influence to reside completely with the burning plains. The war ceased for a while until they discovered that hell's leaders still lived and were on a separate plane of existence. When they realized that we were simply watching the world and not changing it they decided to not fight but grant 2 families the power to repel demons. Those families were the Uchiha and the Senju who would both later found konoha. The future Shodaime Hokage, Hariashami Senju, would later then capture the demons and give them to the great ninja countries as a way to balance the scales of power.

He then remembered how his brothers and sisters were used as weapons of war and how despite trying to prevent this happening the hosts of the demons would be treated as monsters and demons. Diablo knew that this system had to end but as long as the Uchiha clan existed they could not destroy the system of Jinchuriki as they would then be manipulated by those damn eyes. He then felt as the connection between him and the masked man was cut and he was free. He then knew that he would have to be sealed again to both be protected from the masked man and to start planning on what he must do to end this current cycle of hatred and ignorance.

Minato POV-

Minato had just defeated the masked man but he had just escaped promising revenge on the village and there was little he could do to stop his escape. I then saw the kyuubi who was just recently filled with bloodlust calm down and just sat down. It just stopped attacking the village and its defenders and calmly watched everyone. I then went toward the main forces which were being led by the previous hokage, Sarutobi Hiruzen, and the toad sage, Jiraiya, to see what was happening. I arrived to see them as surprised and confused as I was. I then said to them,

"What is going on over here, sensei, jiji? One moment the Kyuubi was striking at us with a fury and know he just stopped and is looking at us."

They just shrugged but we all noticed that a weird glow was surrounding it and then it just shrank and took a new form of a person with blood red hair and strange clothes covered in weird symbols. The kyuubi then walked toward the ninjas and then as if they were controlled the ninjas parted creating a clear path toward the three leaders. He then walked toward us and we felt something different as if everything we knew about the bijuu were false. We realized they were indeed sentient if one could take on a human form at will. He then arrived in front of us and said one simple sentence that changed everything. He said,

" We have a lot to discuss about the future of this world."

Later that night Sandaime POV-

The Sandaime Hokage, Sarutobu Hiruzen, sighed as he realized that what happened tonight had flipped the world upside down in terms of what he knew. Realizing that they had imprisoned the very guardians of this world appointed by the rikudo Sennin himself made him ashamed but it was what they kyuubi, or Diablo as he called himself, asked them to do that made him surprised. They wanted him sealed into a host so that he would be safe from the man who had freed him from Kushina Uzumaki and the unlucky child was the Yondaime Hokage's own son Naruto as he couldn't make another parent's child suffer or make them accept what he couldn't accept himself. They made the seal to allow conversation between naruto and his willing tenet but they were afraid that due to what happened the boy would be persecuted and hurt by the village due to the kyuubi attacking the village even if it was against his will. He at least was satisfied knowing that the boy would be cared for as he knew the entity was not lying and teach him and make him strong. He would also honor Minato's wish to wait to let the village know his ancestry and burden until he could defend himself from any civilians and if ninja fought then he would have the boy guarded by his ANBU forces as well. He then watched as the child fell asleep and knew that though the future would be hard there was hope as well for the future.

End notes- The characters may be a bit ooc but I try to make this work. There are 2 pairings one is done but one is open so give me ideas on what to put. The last thing is I have a note sheet about the demons and how they work as the biju so please read both that and this and review them both as I want to hear what people think of this idea
