Yay! Fanfiction!
I don't happen to own Naruto or Bleach, strangely enough.
It was a cold night in October when the Kyuubi attacked Konoha. Thousands of people died, civilians and shinobi alike. Then, out of the blue, the Yondaime Hokage appeared and teleported away with it. At the heroic cost of his own life, he sealed it away into a child.
This is what most people know about the attack of the Kyuubi. There is another side to this story, however, that only a select few know about.
The release of the Kyuubi occurred during the pregnancy of Kushina Uzumaki, who was with Minato Namikaze's child. This was forced by the appearance of a mysterious man who escaped with Kushina long enough to draw out the Kyuubi from her seal; for she was the Jinchuuriki of the Nine Tailed Demon Fox. The man then teleported in a spiral portal into Konoha, and then summoned the beast.
The 4th Hokage fought off the masked man, and then sealed it into Naruto Uzumaki- the product of Kushina's pregnancy. It was not sealed by any normal seal, however. Minato Namikaze had done the impossible three times that night. First off, he had summoned the Soul King- not just any god. The most powerful of all gods, whose very presence caused all matter to disintegrate. He pulled him off an entirely different universe in another dimension being the second. The third was by far the most impressive, and had the greatest impact on the world. He had forced the most powerful being to obey him.
Not knowing the power of his actions, he made the Soul King draw out a seal on his own child's stomach. Here is where the timeline departed from the norm entirely. With every touch, the soul Kings presence corrupted Naruto's plentiful chakra into reiatsu, the energy of the death gods, which had a knock-on effect on all of his chakra. His heart, not being able to accept the reiatsu died, and was reborn as a shinigami's.
The Kyuubi, having all been sealed into his tiny body howled and shrieked in pain as its entire body was entirely reconstructed as a powerful Vasto-Lorde. He then went into a deep hibernation.
The Fourth Hokage forced the Soul King to leave, and soon died next to his wife, having paid his soul and suffered a claw impaled into his chest. One drop of blood dripped onto Naruto's bawling face.
Prologue is done. Now we can get into the really juicy bits!
