Prologue:
As the sun started to set the 4th hokage, Minato Namikaze was working on paperwork when a chunnin 'poofed' into his room startling the blonde leader.
"Lord Hokage, your wife sent me to retrieve you she said it is time…" the chunnin stated urgently. The hokage looked up at the chunnin with a bland expression the realization hit him and he jumped from his chair out the window and shushined to the hospital at his wife's side.
Kushina Uzumaki was lying on the bed surrounded by doctors as minato approached her side. She looked up into his cerulean eyes and nodded once as she began to go into labor. One hour later it was over and the nurse walked back into the room holding a little blue bundle, just as the bundle was placed into minato's arms a loud crash shook the hospital and the surrounding buildings. Everyone rushed to the window to look outside and were astounded at what stood before the wooden gates of konoha. A giant Ten Tailed black as night wolf, "Looks like the sage of the six paths failed to destroy the true juubi but instead cloned and separated it into the 1-9 tailed demons that already plague this land." Minato sighed. Then he glanced back and watched the life force start to fade from his wife as she lay on the hospital bed barely breathing. He whispered to her "I know what I have to do so do not wait for me I will meet you at shigami's door very soon my love." As he disappeared in a gust of wind she took her last breath and closed her eyes forever.
Kakashi hatake was standing on top of the gates when he heard a gust of wind to his right and glanced away from the wolf to his sensei. His eyes widened at the site of minato standing atop of gambunta the boss summon of the toads standing before the massive demon flying through hand seals. Kakashi I will die when this jutsu is finished I want you to take my son and give him to Jiriya the toad sannin and tell him too train this boy until he is 15 then bring him back to the village. Also tell him to wait until the boy is 10 to tell him his real name and who his family is and what is sealed inside him" minato sighed. Kakashi looked at minato's feet and saw the blue bundle laying there squirming. Minato finished the seals and held his right hand palm forward towards the giant wolf and a black swirl appeared on his palm he then jumped and slammed his palm onto the demons forehead. "Fuuinjutsu Shiki Fuujin (Demonic Soul Sealing Technique) and Shisou Fuuin (Four Image Seal)." Minato cried. The swirl glowed white then the wolf howled in agony as he was absorbed into the seal. As the wolf finally disappeared the swirl glowed silver and minato placed his palm on his son's stomach, the baby started to cry as the seal transferred from minato's palm to the baby's stomach.
When the sealing was complete minato whispered to the little bundle, "goodbye naruto, my son." And with that last whisper he faded from existence.
