Looking at the swollen Truth-Seeking Ball rushing toward him, Ryoma lifted the black blade at his side as his hands quickly formed seals.
"The final blow…"
Under normal circumstances, with his mastery over ninjutsu, he could precisely control chakra and cast techniques without hand seals. However, this technique was something he had only just developed after obtaining Momoshiki's memories, and to bring out its full power, the seals were necessary.
His objective was clear. He had to eliminate Kaguya Ōtsutsuki.
Even the Hagoromo Ōtsutsuki, revered as the Sage of Six Paths, had been unable to kill Kaguya. At best, he had sealed her using Six Paths Chibaku Tensei.
That alone proved one thing. Conventional methods would never be enough to truly destroy her.
Even Ryoma himself had only managed to destroy Momoshiki's physical body by chance, devouring the Karma left behind in the process. That method was extremely dangerous, and Kaguya, having consumed the fruit of the God Tree, possessed far greater chakra and spiritual power. A single misstep would mean failure.
If he wanted to kill an Ōtsutsuki, he needed knowledge from the Ōtsutsuki themselves.
And within Momoshiki's memories, he found it.
The Ōtsutsuki clan possessed a terrifying ability to absorb chakra, far superior to even the Rinnegan's absorption techniques. Their efficiency was higher, and their activation was nearly instantaneous.
Even Ryoma's previous attacks, combining Wood Release and the Rinnegan, had only barely bypassed Kaguya's defenses. They were difficult to absorb, but they still lacked the destructive power to truly injure her.
So he needed something more.
A decisive strike powerful enough to obliterate her body entirely, followed by a method to suppress the Karma-like parasitic revival of her clan.
"Swoosh!"
In the next instant, a blinding radiance erupted within Ryoma's clenched fist, illuminating the entire dimension. The light carried the power of the Six Paths along with senjutsu chakra.
As the energy spread, Kaguya, standing in the distance, felt an unprecedented sense of danger.
But her pride would not allow her to retreat.
"Haah!"
Her chakra surged, pouring into the swollen Truth-Seeking Ball. Its speed skyrocketed, tearing through space like a collapsing star, closing the distance to less than a hundred meters in an instant.
At that moment, Ryoma slowly opened his pale left hand. A sphere of light, no larger than his palm, hovered above it.
He reached out with his right hand and grasped the black blade. With his left, he swept the light across its edge.
In an instant, the radiance transformed into white flames, coating the blade like a divine weapon born from myth.
Gripping the sword with both hands, he swung.
"Swoosh—!"
Black and white energy intertwined as a terrifying slash tore forward. The sword light split the sky itself, scattering the clouds of the Tree World and even cracking open space, revealing a rift beyond.
The heavens rippled like disturbed water. Space and time twisted under the sheer force.
Yet these were only the aftereffects.
The true destruction lay at the point of impact.
The sword light collided directly with the swollen Truth-Seeking Ball.
A deafening explosion rang out.
The world trembled.
At the center of the clash, everything was annihilated. Matter disintegrated under the violent surge of energy, while the land below warped and collapsed, spreading massive fissures across hundreds of kilometers.
The ground split apart like falling dominoes, cracks plunging several kilometers deep. Explosions sent towering plumes of smoke into the sky, while hurricanes spanning hundreds of meters tore through everything in their path. Thunderclouds formed in an instant, flashing with violent lightning.
Kaguya poured all her chakra into the attack, but it was useless.
With a thunderous sound that shook the heavens, the blade cut through the Truth-Seeking Ball.
Split in two.
Even with her vast chakra reserves, she could not overcome the power Ryoma had refined over years of battle.
Every fragment of his strength had been used with absolute precision, not a single trace wasted. The fusion of different energies amplified the attack to an unimaginable level.
Kaguya's Truth-Seeking Ball was like a balloon before a blade.
No matter how large it was, the outcome was inevitable.
The seven-nature chakra within it went berserk, tearing through space and forming a miniature vortex. Yet even amidst the spatial turbulence, the sword light did not slow.
It continued forward, relentless.
"This… this can't be!"
Kaguya stared in disbelief as the blade of light cleaved through the Truth-Seeking Ball and continued straight toward her.
The next instant—
Her figure was completely engulfed.
"AAAAAAAAAAAAAAAAAAAA—!"
A shrill, almost inhuman scream tore from her throat as the overwhelming energy devoured her body and penetrated deep into her core.
The slash carried both Six Paths power and senjutsu chakra, a fusion that the Ōtsutsuki could not absorb.
"I… I can't die… I still have to reclaim my chakra!"
At the very moment her body began to collapse, Kaguya attempted to plant a Karma onto Ryoma.
But as she activated the technique—
It failed.
"What's going on?!"
Her eyes widened in shock.
At some point, a series of sealing runes had appeared above her, descending upon her like a cage. Each one radiated a familiar power.
Kaguya recognized it instantly.
That was an Ōtsutsuki clan sealing method.
"How can he know this?!"
"How can he wield the power of my clan?!"
Countless questions flooded her mind, but she would never receive an answer.
In the next moment—
Her body and soul were completely erased by the sword light.
The attack did not stop.
The radiant slash surged forward like a cosmic torrent, sweeping across the entire Tree World. Within moments, everything in this dimension was consumed. Matter broke apart into countless particles wherever the light passed.
With a single strike, Ryoma destroyed the entire space.
Then—
"Crack… crack…"
A series of sharp sounds echoed as the dimensional structure began to collapse. The space fractured like glass, and violent spatial currents poured in through the cracks, eroding what remained of the world.
Seeing this, Ryoma made his decision immediately.
He opened Yomotsu Hirasaka and stepped through.
In the blink of an eye, he returned to the real world.
Before him stood the towering God Tree, its roots spreading across the land.
Ryoma brought his palms together.
Having inherited the power of the Sage of Six Paths, he now wielded both Yin and Yang Release. By combining them, he unraveled the Infinite Tsukuyomi cast upon the world.
Light spread.
The illusion shattered.
One by one, people awakened from their cocoons.
Floating high in the sky, Ryoma looked down at the restored world and gave a small nod.
"It's finally over…"
