Kaguya's sleeves billowed as she stared coldly at Hyuga Gakuya.
"Now, do you still dare to claim you can defeat me?"
Gakuya's expression remained calm, completely unaffected by Kaguya's overwhelming presence.
"No matter how powerful you become, the outcome won't change."
Kaguya said nothing more. A massive wave of chakra burst from her body, surging straight toward Gakuya.
Then, she unleashed her Eighty Gods Vacuum Attack, flurries of phantom fists raining down on him with terrifying speed and force.
Gakuya responded in kind, countering each strike with precise, fluid movements.
His combat experience allowed him to redirect the attacks using the subtle strength of Gentle Fist, while Kaguya fought without any concern for chakra expenditure—every blow was executed with full power.
Their clash quickly became a deadlock, neither gaining the upper hand.
...
At that moment, aided by the Flying Thunder God and Kamui, Sasuke and Naruto finally broke into the ancestral dimension.
"We're here to help!" Sasuke shouted, and the power of his Susanoo surged. He formed a massive arrow and fired it straight at Kaguya.
Not to be outdone, Naruto gathered the chakra of all nine Tailed Beasts into his palm, forming a Rasengan with nine distinct chakra attributes and hurled it at her.
"Sage Art: Super Tailed Beast Rasenshuriken!"
Kaguya, currently held at bay by Gakuya, couldn't react in time. The Rasenshuriken and chakra arrow struck her squarely, engulfing her in a massive explosion.
The blast swallowed her entirely, and when the smoke cleared, her body was riddled with wounds.
But her near-immortal body rendered the injuries trivial. However, Naruto's use of Tailed Beast chakra had triggered a reaction within her.
The Ten Tails' chakra inside her began to stir violently.
White flesh began to bubble from her body, consuming her entire form—she was being swallowed by the Ten Tails' power.
This was her fully Tailed Beast-transformed state—a massive white rabbit, grotesquely bloated, with the faces of all nine Tailed Beasts embedded across its body.
Forced into full transformation, Kaguya now stood as a monstrous behemoth.
Ten enormous arms extended from its back, reaching in all directions toward Gakuya, Sasuke, and Naruto.
Sasuke vanished in a blur, activating his full-body Susanoo and slashing at the monstrous arms with his katana.
Naruto summoned the full strength of Kurama again, launching another Rasenshuriken.
But Kaguya's transformed arms were incredibly powerful. She caught both attacks effortlessly and absorbed them into her body.
Ordinary attacks had no effect on her anymore.
Behind Gakuya, his nine Truth-Seeking Orbs fused together as he prepared to unleash the Golden Wheel Reincarnation Explosion once more.
But before he could act, the massive rabbit body began to grow, its form melting like snow, revealing an enormous, ever-expanding Truth-Seeking Orb.
This was Kaguya's final ability—Expanding Truth-Seeking Orb.
A maximized Truth-Seeking Orb, formed by absorbing the chakra of shinobi captured by the God Tree.
Though it shared the same structure as Gakuya's Truth-Seeking Orbs, its size was on an entirely different scale.
As recorded in the Book of Battle: "It erases all forms of existence, reducing the world to nothingness—while simultaneously acting as the seed of a new space."
Now, facing it directly, Gakuya fully understood those words. If this orb continued to expand, it would swallow everything around it.
And it was fueled by what seemed to be infinite chakra.
As the others stared in stunned disbelief, the massive orb ballooned to the size of a mountain, submerging the ground of the ancestral realm beneath it.
It grew like a black hole, devouring all in its path.
But Kaguya revealed herself again.
"We need to end this quickly. That thing is still growing. You two draw her attention—I'll deliver the final blow."
Gakuya had been holding back a trump card—an ultimate technique he had studied and refined over time. This was the perfect moment to use it.
"Leave it to us!" Naruto replied, creating a swarm of shadow clones that charged toward Kaguya.
"Don't worry. I've surpassed Itachi," Sasuke said calmly, rushing forward alongside Naruto.
...
Meanwhile, Gakuya activated Kamui and vanished into its separate dimension to begin gathering the power for his final attack.
He sat cross-legged, steadily drawing in the power of both the Tenseigan and Rinnegan.
Outside, Naruto and Sasuke clashed with Kaguya, giving it their all. Naruto, empowered by all nine Tailed Beasts, unleashed Rasenshuriken after Rasenshuriken through his clones, while Sasuke's Susanoo fought with unmatched intensity.
They managed to just barely keep her at bay.
Kaguya rained down phantom fists, destroying Naruto's shadow clones one after another.
"This isn't working, Sasuke!" Naruto yelled.
"Just hang on a little longer—wait for Gakuya-senpai!" Sasuke shouted back.
But then, Kaguya unleashed a violent surge of power that sent both of them flying.
"Hahahahaha! Did you really think this would be enough to defeat Mother? Hyuga Gakuya's probably run off using Kamui already, and you two fools are still clinging to the hope he'll save you!"
Black Zetsu slithered out from Kaguya's sleeve, mocking them loudly.
"Gakuya's just a two-faced traitor—always chasing profit. And you two… loyal idiots! Dying under Mother's hands—maybe next life, choose your allies better!"
"Don't you dare talk about Mokushū-san like that!" Naruto roared.
"You bastard, you're dead!" Sasuke shouted in fury.
To both of them, Gakuya had already become a true hero who had sacrificed everything for the ninja world. They couldn't tolerate anyone slandering him.
In an instant, Sasuke used Amenotejikara to swap places with Kaguya—placing her right next to Naruto.
Naruto struck instantly, slicing off her right arm with a precise hand chop. Black Zetsu, still attached, was severed along with it.
As Kaguya's severed arm and Black Zetsu fell, she quickly activated Yomotsu Hirasaka, opening a portal to escape Naruto.
Chakra surged from her once again, and her wound began to regenerate rapidly.
...
Back in the Kamui dimension, Gakuya had finally brought his Tenseigan and Rinnegan powers to their peak.
His eyes were tightly shut, but on his forehead, a third eye had emerged.
The pupil was a deep, dark gold, like an endless cosmic vortex—containing the primordial chaos of the universe's birth.
Soft golden light flowed across its surface, within which ancient and intricate runes could faintly be seen.
