After completing the rapid sequence of hand seals, mysterious runes appeared beneath Yoruha's feet. These runes transformed into black chains that shot toward the iron gate's lock, which held the Nine-Tails captive.
Buzz~
The moment Yoruha's chakra surged into the seal, intricate symbols emerged on the gate's lock.
Yoruha immediately opened his eyes, furrowing his brows.
"So complex… As expected, the Fourth Hokage's Eight Trigrams Seal isn't something simple."
"But at most, it just consumes more chakra."
Yoruha increased the flow of his chakra.
Rumble!
An overwhelming surge of chakra poured into the sealing lock.
Even the Nine-Tails was shocked by the sheer amount.
"What kind of monster is this brat? How can someone his age have such an insane amount of chakra?"
As Yoruha continued to channel chakra, the Nine-Tails could feel the previously weakened seal strengthening once more.
"Stop!"
Boom!
Realizing the seal was becoming stronger, the Nine-Tails became furious. It slammed a massive claw against the iron gate, causing a violent tremor—but it didn't affect Yoruha's technique at all.
"I said stop, you damn brat! You bastard, are you planning to lock me in here forever?"
"You vile human! I'll kill you! Kill you!"
Roar!
Boom! Boom! Boom!
The moment the Nine-Tails realized Yoruha could actually reinforce the seal, it became desperate.
It had been waiting for years, knowing that every time Naruto relied on its chakra, the seal weakened a little more.
It wouldn't be long before it could finally break free from this dark, oppressive prison.
But now, Yoruha was ruining everything.
Keeping it locked inside Naruto forever? What a joke!
Roar!
Seeing that Yoruha wasn't stopping—wasn't even acknowledging its fury—the Nine-Tails lost its patience.
It began gathering chakra.
A deep red sphere of compressed energy rapidly formed in its mouth—a Tailed Beast Ball.
"Die, you little brat!"
Feeling the terrifying energy of the Tailed Beast Ball, Yoruha frowned slightly.
But he didn't stop.
He wasn't sure if the Nine-Tails could actually harm him in this space.
Meanwhile, outside—
A crimson shroud of chakra began to form around Naruto's body.
The color of the Tailed Beast Cloak darkened, its intensity growing.
Naruto's consciousness was fading.
Kakashi's eyes widened in alarm.
He tried to stop Naruto, but the instant his hand touched the shroud, he was burned.
Stunned, Kakashi muttered, "So this is the Nine-Tails' chakra… The corrosive power is this strong?"
Sasuke and Sakura, standing nearby, were equally shocked.
"Naruto… has such terrifying power sealed inside him?"
Yoruha's consciousness was still inside Naruto's seal, leaving his body motionless in the real world.
Kakashi wanted to intervene, but he feared that interrupting Yoruha might put him in danger.
Left with no choice, he turned to Sasuke and Sakura.
"Sasuke, Sakura, take Tazuna and get him far away from here."
"If Naruto loses control, he could hurt them."
Kakashi regretted not being more prepared for this situation.
He looked at Yoruha's emotionless face, deeply worried for his safety—but at this moment, there was nothing he could do.
Sasuke and Sakura, though concerned for both Yoruha and Naruto, nodded and moved to carry out his orders.
But for now, they could only follow Kakashi's orders and move Tazuna's family to safety.
Fortunately, Tazuna's home was far from the town—if Naruto lost control, the destruction would be catastrophic.
After Sasuke and Sakura left, Kakashi remained by Yoruha's side, watching him and Naruto with a tense expression.
Yoruha showed no emotion, while Naruto's face twisted in pain. The crimson shroud of the Tailed Beast Cloak darkened further, and even without touching him directly, Kakashi could feel the sheer, oppressive menace of the Nine-Tails' chakra shaking his very soul.
The furniture and objects in the room trembled under the constant waves of chakra, cracks forming throughout.
The blood-red chakra swirling around Naruto radiated immense pressure, making even Kakashi feel suffocated.
Inside Naruto's seal, Yoruha was also under immense strain.
The Tailed Beast Ball in the Nine-Tails' mouth was fully charged. He wasn't sure if, in this space, its attack could actually threaten his life.
Yet, Yoruha did not stop.
He continued pouring chakra into the seal.
The runes beneath his feet expanded, and the chains formed by the symbols surged wildly into the sealing lock.
Sealing techniques consumed an enormous amount of chakra, but Yoruha's reserves were vast—otherwise, he wouldn't have been able to sustain the technique for so long.
The Nine-Tails saw that Yoruha remained unfazed despite its threats.
Its fury exploded.
"Die, you little brat!"
Boom!
The Nine-Tails unleashed the Tailed Beast Ball.
Rumble! Rumble! Rumble!
The attack crashed into the iron gate sealing it away.
A blinding light illuminated the entire space.
The monstrous chakra shockwave instantly struck Yoruha.
He hadn't expected that even in this realm, the Nine-Tails' chakra could actually harm him.
"Ugh—!"
Caught off guard, Yoruha took the full brunt of the attack.
The impact blasted him backward, slamming him hard against the wall.
In the real world, Yoruha coughed up blood.
His crimson blood splattered onto Naruto—
But the moment it touched the Tailed Beast Cloak, it was instantly corroded and burned away.
Kakashi, standing beside Yoruha, tensed up and was about to intervene.
Yoruha's face had gone pale.
Since arriving in this world, this was the first time he had ever coughed up blood—the first time he had suffered such a serious injury.
Just as Kakashi was about to wake him, Yoruha finally spoke.
Though he was clearly in pain, his voice remained cold and firm.
"Kakashi-sensei, I'm fine. Don't worry."
Kakashi halted. Yoruha's consciousness had returned.
"No, this is too dangerous. If something happens to you, how am I supposed to explain it to the Hokage?"
Kakashi's expression darkened.
What he truly wanted to say was that he didn't want Yoruha taking such a risk in the first place.
Seeing Yoruha spit blood had shattered his patience.
At that moment, he realized something—
Yoruha's safety mattered far more than the Nine-Tails sealed within Naruto.
But Yoruha only shook his head, his face serious.
"I'm fine. I was just testing whether the Nine-Tails could actually harm me in this space. I let my guard down—that was my mistake. It won't happen again."
"Kakashi-sensei, please leave. Stay away from me. I don't want you getting caught up in what happens next."
Kakashi frowned.
"I'm not leaving you alone in such a dangerous situation."
"Kakashi-sensei, trust me. I need to handle this. If you stay, I won't be able to focus properly."
For the first time, Yoruha spoke to Kakashi in such a serious tone.
Kakashi looked into Yoruha's determined eyes.
He knew that staying would only be a distraction.
Even though he was worried, Yoruha's expression told him there was no turning back.
With no choice, Kakashi sighed, gave one last glance at Yoruha and Naruto, then disappeared from the room.
