With the Nine-Tails stepping in, Muren Uchiha's assault was immediately suppressed.
There was simply no helping it—Kurama's chakra was overwhelmingly powerful, so overwhelming that even in pure chakra form it could clash head-on with a full-body Susanoo without losing ground.
And Kushina, already in her tailed beast transformation, possessed a body made of chakra as well. Physical attacks meant nothing to her.
Even Muren Uchiha's dōjutsu-based surprise attacks failed every time. With Minato Namikaze's Flying Thunder God Technique always ready, not a single attempt succeeded.
This only made Muren increasingly agitated.
And it wasn't just him—on the other side, Madara Uchiha was being utterly crushed, practically unable to tell up from down.
"Give it up, Madara Uchiha. Everything was decided long ago."
"The moment I became a Jinchūriki, it was already set in stone."
Neither Susanoo nor Rinnegan: Limbo–Border Jail had any effect whatsoever in the face of the Truth-Seeking Balls.
Though containing the full Yin-Yang and Five Elements power, the Truth-Seeking Balls easily surpassed Kekkei genkai and Kekkei tōta.
Simply put, they were the perfect measuring material. Anything not at the Six Paths level was worthless in front of them.
A single touch shattered it. A single brush erased it.
Of course, that wasn't absolute. There was one other way to counter the Truth-Seeking Ball—Senjutsu.
Unfortunately, the current Madara Uchiha simply lacked the ability to use Senjutsu.
"Impossible! I am Uchiha Madara!"
"Do not underestimate me!"
"Limbo: Border Jail!"
Shadows could be remade as long as the Rinnegan held enough energy. He had only four shadows, but they were still Rinnegan abilities—deadly and relentless.
Madara had schemed for decades, even faking his own death. There was no way he would accept defeat.
Kazuyama understood that clearly.
"Ah… people with obsessions really are a pain."
"You're already a dead man. Why cling to obsession? Wouldn't it be better to go find your beloved Hashirama down below?"
Kazuyama didn't even move. Against Limbo's attacks, the Senjutsu chakra within him sensed the threat a second ahead of time. Crystal Release blocked it—
and then a Truth-Seeking Ball finished the job.
He offered Madara no path forward, no room to breathe.
"I told you earlier, these Truth-Seeking Balls aren't mine."
"What's really mine is far stronger."
"Though this is my first time using it… and to settle that old man's instructions, I'll have to try."
"Letting you be the witness for my first use—consider it an honor."
With a flick of his wrist, Kazuyama let the staff melt back into a Truth-Seeking Ball.
Nine of them floated, turning slowly in the air.
Then he pressed his palms together.
Boom.
In the next instant, he practically performed an explosive transformation—his upper clothing vanished, revealing his body covered in intricate markings.
These markings were transparent at first, then turned white as chakra flowed into them.
Immense chakra surged upward, mixed with pure Senjutsu energy.
The powers of two Kekkei Mōra—Transparent Escape and Crystal Release—flared into view.
"Yin and Yang united—that is the path of the Six Paths."
"My Yin is Transparent Escape. My Yang is Crystal Release. Unlike you Uchiha and Senju, I forged my own path."
"With the Sage Body I achieved on my own, I now stand at the level of the Rikudō Sennin himself."
"And to reach this power, I don't need nine Tailed Beasts."
Because I have the System.
As the two Kekkei Mōra fused, the markings on his body lifted away and gathered in the air as streaks of light.
They formed magatama—each crystalline, each shining like a flawless diamond.
Madara watched Kazuyama's "tricks" unfold and attacked again.
But it was pointless. His attacks couldn't get near Kazuyama—everything that approached simply disintegrated into dust.
"I wondered what shape to use—Truth-Seeking Balls are too ugly."
"So? How do these magatama look? Much better than round blobs, right?"
Once all nine magatama solidified, Kazuyama smiled softly. With a wave, the magatama began orbiting around him.
He looked at them with obvious satisfaction.
Madara, meanwhile, had lost all inclination to speak.
With each magatama's appearance, the pressure increased—
enough to draw a bead of sweat from the forehead of a man who once ruled the battlefield as a king.
"Thinking they look unimpressive?"
"Well, let me tell you—these magatama surpass the Truth-Seeking Balls in certain aspects."
"For example—this."
Seeing Madara tense up, Kazuyama extended a finger and lightly tapped forward.
All nine magatama suddenly vanished.
At the same moment, Madara's instincts screamed—death.
"No—!"
"Swap!"
He switched places with a Limbo shadow instantly.
A split second later, the shadow vanished.
Madara was left stunned, unable to understand what had just happened.
"Still don't get it?"
"The Truth-Seeking Ball is the final form. It destroys everything except Senjutsu and Six Paths power."
"My magatama work the same way. But because they were forged through Transparent Escape and Crystal Release combined, they wield both powers."
"Erasure—and creation."
As he spoke, a single magatama reappeared at the spot Madara had stood.
The other eight remained unseen.
"Madara Uchiha, farewell."
"The ninja world doesn't need you. Your existence only deepens its sorrow."
Kazuyama's killing intent sharpened. He'd wasted enough time on Madara already.
The remaining magatama shot toward Madara like a volley of execution spears.
If this attack landed, Madara Uchiha would vanish completely from existence.
"Hmph! I will never submit!"
"My ambitions remain unfulfilled!"
"Kazuyama Gekkō, even you cannot stop me!"
"Summoning Technique!"
Madara would never accept his fate—not then, not now.
If he were the kind to yield, he would've surrendered the day he lost to Hashirama. Instead, he planned for years, and returned revived and ambitious.
He swapped places with his shadow again, letting it take the hit, and swiftly completed the Summoning Technique.
The Demonic Statue of the Outer Path materialized.
The moment Kazuyama saw it, he immediately understood Madara's intention.
