Only then did Kazuhiko notice that the iron box was also covered with intricate seals.
Previously, the seals had been so densely layered that they appeared inconspicuous amidst the chains.
As the iron casing was released, the seals were unveiled, and Kiyoshih took a step forward, inspecting them with a half-smile of disdain.
"This sealing technique is rather crude..."
With only one step remaining, the iron box could be opened.
"Roar!"
Suddenly, a deafening roar erupted from the iron box, filling the air with an overpowering pressure.
The nearest Kiyoshi, who held the key, trembled slightly.
Ignoring the key in Kiyoshi's hand, Kazuhiko gave him a determined look and said, "Leave it to me!"
Kiyoshi and the other clan members on the battlefield immediately felt reassured.
Handing it over to the Kazuhiko meant there would be no issues.
Kazuhiko unleashed his Reiatsu to counter the tailed beast's coercion.
Immediately, the two opposing forces clashed in the void.
"Roar! Roar—!"
As if provoked, the Six Tails within the iron box roared again, this time clearly audible to everyone.
"It's just a tailed beast!"
"Release your Reiatsu at full power!"
Kazuhiko's Reiatsu surged like a violent storm.
"Ow...woo...woooo..."
The tailed beast seemed bewildered by Kazuhiko's Reiatsu, emitting a sound that almost sounded plaintive from the iron box.
But strangely, it sounded somewhat affectionate.
Within Kazuhiko's Reiatsu, he left a message for the tailed beast.
"From now on, you will be part of my Uzumaki clan, the tailed beast of the Land of Whirlpools. You will reside within the Jinchūriki's body obediently."
"Kushina is a kind-hearted girl, and I'm sure you two will get along well. You can discuss your desires and what you'd like to do with her."
"But if you ever entertain ill intentions, I won't be as forgiving. Do you understand?"
Kazuhiko's voice resonated within the Reiatsu, and he believed that the tailed beast could hear it.
"I, I understand, please don't hurt me..."
Suddenly, a meek voice echoed in Kazuhiko's mind, akin to a frightened child.
It made Kazuhiko feel like an adult bullying a child.
"Well, if you behave, there won't be any harm. Get along with Kushina, and you can discuss whatever you like with her. We can coexist peacefully."
"You can tell her your preferences, and we'll do our best to accommodate you."
"If you cooperate, there won't be a need to confine you."
"You can follow Kushina, play, take walks—whatever you both desire."
Kazuhiko's voice softened, for a combination of carrot and stick was often effective.
"Really? That's great. I've been trapped in this iron box every day, and the host never talks to me. I'm so bored that I can only sleep all day."
Kazuhiko offered a reassuring response, assuring him that he would keep his word.
Kazuhiko wouldn't allow Kushina to be treated as a mere vessel.
Kazuhiko inserted the key into the iron box, and with a final turn, the box slowly opened.
"Crack!"
The scene inside was revealed, and a man, almost emaciated, sat cross-legged within the iron box.
He silently gazed at Kazuhiko and he is the Jinchūriki of the Kirigakure Six Tails.
For years, he had been confined to this 5×5×5 iron box, subjected to regular feeding and cleaning. Perhaps, for him, it was a form of relief.
"Cough cough... What is your next command?"
He coughed and asked slowly, indicating that someone from Kirigakure had briefed him on the situation.
Kazuhiko gave him a sympathetic look; it was truly pitiable to have one's prime years spent locked in an iron box like this.
He must have been a talented individual from Kirigakure.
"What is your name?"
He hesitated for a moment, surprised by the question, as it had been a long time since anyone had asked him his name.
"I... I am called Yūrein Hone."
"Alright, Yūrein Hone, you will cooperate with us from now on."
Kazuhiko said before turning away, letting the Uzumaki clan members carry Yūrein Hone out.
They placed him on the other side of the sealing circle, with Kushina on one side and Yūrein Hone on the other. The entire formation of sealing incantations encircled them both.
Kiyoshi stepped forward to inspect the seals, finding no issues.
Turning to the valley, the voices of Uzumaki clan guards echoed from all directions.
"East, clear."
"West, clear."
"South, secure."
"North, clear."
After a final examination of the valley, they were ready.
"Let's begin!" The twelve elders simultaneously formed seals, their gestures and breathing perfectly synchronized.
All at once, the seals, like swimming tadpoles, swarmed around Uzumaki Kushina and Yūrein Hone.
Gradually, from Yūrein Hone, a viscous white Chakra in the shape of Katsuyu emerged from his abdomen.
"Adamantine Sealing Chains!"
Without waiting for further inspection, the elders bellowed.
Chakra chains materialized out of thin air, wrapping themselves tightly around the Six Tails.
"Eight Sign Seal!"
In an instant, the colossal Chakra figure of the Six Tails was gradually sealed into Uzumaki Kushina's abdomen.
"Ahhh!"
Uzumaki Kushina screamed in pain, but eventually, the Six Tails was sealed.
"Success! Kushina of the Land of Whirlpools is now the Six Tails Jinchūriki!"
