Screams rang throughout the Village Hidden in the Leaves the Nine-Tails rampage through it with deadly efficiency. The ninjas were doing their best to try and fight it off but the threat was too large, their only hope would be their Hokage: Minato Namikaze.
Minato had just finished off the Masked Man who he assumed to be Madara Uchiha. Madara had attacked him and his wife Kushina while she had just gotten done birthing two twins. One boy with yellow tufts of hair and one girl with red tufts of hair.
The boy was named Naruto and the girl was named Hanako. As he stood over his newborn children and his unconscious half-dead wife, Minato knew he had a choice. Either sacrifice his village for his family or sacrifice his family for the village.
The Nine-Tails roared once again and brought down more of the village. At that point, he knew what choice to make, all be it a heavy one at that. Minato went through some hand signs and slammed his hand down on to the grass which be was standing one.
A sealing alter appears with candles circling it. Minato places the twins on the altar and goes and Kushina stirs and wakes up. She notices the twins on the altar and she knew what her husband was going to do. She begins to pleas him to stop and says the reseal the Nine-Tails in her.
Minto refuses simply say that the beast would break out since she was so weak right now. Minato goes through hands signs for a special seal called "The Reaper Death Seal". At the cost of one's life, the user can seal anything into themselves, an object, another person, or into the belly of the reaper.
Minato finished the last hand sign and the Grim Reaper appeared behind him. The air felt cold and dark from the presence of reaper, causing everybody to stop in their tracks out of fear of this feeling. Even the Nine-Tails stopped rampaging to see what where the foreboding feeling is coming from.
Minato began the sealing. The Nine-Tails, now noticing what's going on begins to struggle against the feeling and attempted to stop Minato and kill the twins by stabbing them with his claws. Unfortunately, that did not happen as yellow chains made of Chakra wrap around it.
These chains came Kushina who was on her hands and knees with the yellow chains coming out from the small of her back. "Minato hurry up, please..." she pleaded as the beast began to struggle even further.
Suddenly one of the Nine-Tails arms becomes free and once again attempts to kill Minato and the twins. Kushina now realizing that this would be her last night alive jumps in front of the twins. The claw goes straight through Minato and Kushina but with their combined efforts they managed to push the claw into the ground instead of the twins.
"D-damn it," Minato says as he coughs up blood.
Minato begins to seal the Nine-Tails into his children by splitting it into Yin And Yang chakra. Minato forces the Yang into Naruto and the Yin into Hanako. The Nine-Tails fades away as its chakra was sealed into the newborns until it was gone completely.
Minato and Kushina drop down and they blow crawl over to the twins and begin to say their final goodbyes: "Naruto, Hanako, we're sorry that we won't be able to raise you. We love you..." Minato said weakly before closing his eyes. Anyone could tell he was dead just from the way be looked.
"Hey, guys just to repeat what your father said: we love you more than the world and we're sorry that we had to do this to you. Just remember to stay together. We love you..." Kushina faintly just before she closed her eyes as well.
