"Kushina, I'll use the last of your chakra to ensure you can see Naruto. I'll combine our chakra with the Eight - Trigrams Seal to suppress the Nine - Tails. And I'll deal with the Nine - Tails. Since I'm not a Jinchuriki, I can only use the Reaper Death Seal."
"But that technique will cost the user..."
"I know. The Nine - Tails can't be killed. Otherwise, the balance among the villages will be broken."
Tailed beasts are village - level combat forces. Unless it's a last resort, they must never be allowed to appear on the battlefield.
Once a tailed beast dies, it will be reborn somewhere in the world after a while. At that time, the tailed beast will be free, and any village can capture it.
If the Nine - Tails is killed and then re - born, whether it takes revenge on humans or is captured by other villages, it's not a good thing for Konoha. Moreover, there's Obito, who can control the Nine - Tails, lurking in the dark...
"I'll only seal half of the Nine - Tails, and it will be sealed with me forever. The other half of the Nine - Tails will be sealed into our son."
Kushina was shocked and her body trembled. The life of a Jinchuriki... was not something a child should bear!
"The controlled Obito will surely stir up a bloodbath in the future. Just as Jiraiya - sensei's prophecy said, I believe our child is the one who can stop him! As a Jinchuriki, he will carve out the future! I firmly believe this!"
He looked at his wife with a smile, then said to Kiyosuke, "Kiyosuke, I'm entrusting Naruto to you. This is my last request!"
"Since you've decided, then rest assured. I won't let this child get hurt in the slightest. This kid is clearly going to become the Hokage! I'll train him to be the Hokage!"
Perhaps this was fate. Minato and Kushina would die on the day Naruto was born.
Kushina forced a smile and said, "I just hope he can... grow up safely... and be happy all his life. Kiyosuke, I'm sorry to trouble you... to take care of him. I'm sorry, I've caused you trouble. I'm sorry, Kiyosuke. I'm sorry, Naruto!"
Tears streamed down her face as she hugged her son and cried softly.
Minato immediately formed hand - seals: Si, Hai, Wei, Mao, Xu, Zi, You, Wu, Si, and finally, he joined his hands together!
"Reaper Death Seal!"
A cold chakra emerged within Kiyosuke's perception. He could sense the icy - cold chakra behind Minato, as if it came from hell.
"Trust our child. He's the son of both of us!"
"I'll use the Eight - Trigrams Seal to seal your chakra together with the Nine - Tails into Naruto's body. When he tries to control the Nine - Tails, you can give him a hand."
"He's our son. That's exactly why I don't want him to bear such a responsibility. You know what the life of a Jinchuriki is like. And you don't have to use the Reaper Death Seal! You could clearly... live to take care of Naruto!"
Minato was silent. Kiyosuke said softly, "Because he loves you, Sister Kushina."
Kushina felt a pang in her heart and started crying. Minato said, "Our whole family are ninjas."
"As a mother, you can teach Naruto many things that I can't. It's not just for you, but also for Naruto."
"Protecting our son is also my responsibility as a father."
Kiyosuke saw the Third Hokage coming and knocking on the barrier. He ran over, leaving space for the couple to say their goodbyes.
He came to the Third Hokage and said through the barrier, "Third Hokage, don't waste your energy. Minato - sensei has already used the Reaper Death Seal and is ready to sacrifice himself to seal the Nine - Tails and make his son the Jinchuriki."
"What? Why didn't you stop him?" Hiruzen Sarutobi was shocked. How long had Minato just taken office? He was clearly already prepared to sacrifice himself to seal the Nine - Tails.
"I couldn't," Kiyosuke shook his head. The voice of the Nine - Tails came from behind, "Damn Fourth Hokage!"
A large mass of chakra separated from the Nine - Tails and entered Minato's body.
A big hole appeared in the clothes on Minato's stomach, and a sealing spell appeared on his abdomen.
"It's already started."
Having lost half of its chakra, the Nine - Tails' body also shrank by half. The Adamantine Sealing Chains that had been tightly wrapped around it became loose, and their binding power weakened. Kushina couldn't hold on for much longer.
If it weren't for the strong constitution of the Uzumaki clan, Kushina would have died the moment the Nine - Tails was being extracted.
"It's really the Reaper Death Seal. He really used it!"
Hiruzen Sarutobi watched. Kiyosuke left and came to Minato's side, saying, "You can leave your back to me, Minato - sensei."
"Okay, I'll leave it to you."
Minato summoned the altar for sealing the Nine - Tails.
"Damn it, you want to seal me again? And into such a brat?!"
"Cough, cough." Kushina couldn't hold on any longer and started coughing. Minato, worried about his wife, let his guard down.
"Now!!!"
The Nine - Tails raised its claws and stabbed towards Naruto, trying to kill the baby.
"Not a chance!!! Fire Fist!!!"
The Fire Fist burst out again, repelling the Nine - Tails' claws with one strike. Kiyosuke said, "Hey, hey, don't ignore me. I'm a ninja who knows Sage Mode, you know."
"Kiyosuke Asakawa, you bastard!!! Even if I've been sealed half of my power by the Fourth Hokage, I can still kill you right now!"
"Then come on! I'm immune to physical damage. What can you use to fight me?!" Kiyosuke jumped up and kicked the Nine - Tails. "I could suppress you in your complete form, not to mention you only have half of your power now. Although I'm not the First Hokage, it's more than enough for me to hold you back."
The Nine - Tails winced in pain and slapped at him with another paw.
Clang!
The Adamantine Sealing Chains tightened, forcing the Nine - Tails to stop its movement. Kiyosuke's attacks came again, and countless fireballs landed on the Nine - Tails.
"Summoning Jutsu!"
Taking the opportunity, Minato used the Summoning Jutsu and gave the key to the Eight - Trigrams Seal to Gamatora of Mount Myoboku, so that Naruto would have a way to open the seal of the Nine - Tails in the future.
"Naruto, be a good boy. Don't cause trouble for Big Brother Kiyosuke. Don't learn bad things from him. Stay away from the three taboos of ninjas and be careful of Jiraiya - sensei," Kushina said with a smile to her beloved son. "Eat well and don't be picky..."
She gave a lot of instructions. There were so many things she wanted to say, but her life force was fading away, and her time was running out.
"I'm sorry, Naruto. I really, really, really want to watch you grow up. I'm sorry, I'm sorry, I'm sorry. I love you, Naruto!"
"Naruto, I love you too. Forgive me, son. Eight - Trigrams Seal!"
A bright light flashed, and the Nine - Tails, which had been fighting Kiyosuke, suddenly disappeared and was sealed into the body of a small child.
