Speedrunning Naruto to the Top

In the Core Dimensions, Ōtsutsuki Kaguya's figure materialized out of thin air. She lay on a red, wave‑patterned surface, wriggling like a white insect.

It was not that she was struggling to crawl; the torn flesh at her wounds was simply regenerating at an astonishing speed.

At this moment Kaguya no longer resembled her former self—she looked like a puddle of white sludge.

Had the consciousness inhabiting this body been anyone other than the Rabbit Goddess who had eaten the Chakra Fruit, then, faced with such catastrophic damage, the Ten‑Tails' will would already have seized the chance to rebel—as would have happened had this been Uchiha Madara. He would have turned into the fully bestial Ten‑Tails' jinchūriki long ago.

His vision would have become the blank Rinnegan, his blue‑black straight robe fluttering like the out‑of‑control Uchiha Obito: outwardly still human, but inside nothing more than a feral beast.

To Kaguya, however, these wounds were no more than a chakra‑draining inconvenience.

Just as the upper half of her body was about to finish repairing itself, a black fissure cracked open in the green sky. Izayoi's silhouette shot out of it.

Seeing Kaguya's head about to re‑form, Izayoi raised a hand, condensing a golden sphere of light and firing it downward.

A terrifying suction ripped the Ten‑Tails' chakra from Kaguya's body and drew it into the sphere.

When her skull finally regenerated and her mind snapped back into place, Kaguya's expression changed drastically.

Without a moment's hesitation she used Amenominaka again and vanished from the Core Dimension.

She reappeared above a vast green ocean—the Acid Sea dimension of Amenominaka.

While she burned chakra to finish healing, Kaguya muttered darkly, "How did that man find the my coordinates? Does his eye possess a marking technique in addition to that jutsu that absorbed my Eighty Gods Vacuum Attack?"

She unleashed the Byakugan's x‑ray vision on herself, searching for any foreign chakra.

Nothing. No markings at all.

That meant Izayoi had left no tag on her—or on the sacrifice.

Either he could pinpoint her chakra accurately while traveling the space‑time tunnel, or his dōjutsu could mark a target without leaving any trace.

Kaguya favored the latter theory. She herself wielded Yomotsu Hirasaka, yet could not peer through the bent gateway of a tunnel to see chakra in another dimension. Otherwise she would have flushed out Ōtsutsuki Isshiki ages ago.

To test her guess, she stayed in the Acid Sea instead of returning to the super‑gravity space to find Black Zetsu. Could Izayoi track her here?

He did not keep her waiting.

In less than three minutes a fissure opened above the green sea.

The instant it appeared, Kaguya loosed a bone arrow, hoping to catch Izayoi off guard—yet he did not emerge.

The arrow flew cleanly into the black portal, and the mechanical scraping sound never came.

A heartbeat later Kaguya's face went white.

A blinding white slash streaked across the sky. Kaguya's body was sliced clean in two—and vanished again without warning.

Izayoi, having once more combined Heavenly Transfer Technique with Flying Thunder God to ambush her, shook his head. "There's no sense of achievement at all."

Give a child a gun and at least an adult will feel a little tension.

Yet Ōtsutsuki Kaguya, with her ten dazzling pedigree traits and a basketful of Kekkei Mōra, was—through Izayoi's eyes—still inferior to Uchiha Madara.

If he did not know the plot—that Madara could never gain that many Kekkei Mōra—Izayoi would not even have allowed Madara to become the Ten‑Tails' jinchūriki.

But now, neither Madara nor Kaguya could put him under the slightest pressure.

The only difficulty was that Kaguya could not be killed outright. Like Hagoromo and Hamura a thousand years before, he had to drain her chakra over a long period and then seal her.

Izayoi did not know Six Paths: Chibaku Tensei; he lacked sealing power. His only option was to siphon her chakra again and again until nothing remained—at which point the goddess' consciousness inhabiting Madara's corpse would simply fade away.

A branch sprouted once more from Izayoi's body. Forming a chakra orb at its tip, he activated Yomotsu Hirasaka and left the Acid Sea.

He tracked Kaguya to the Desert Dimension. This time he was greeted not by All‑Killing Ash Bones or the Eighty Gods Vacuum Attack but by a sky‑darkening sandstorm and countless razor‑sharp sand lances.

The moment Kaguya had shifted here—still reeling from Izayoi's combo—she fused with the environment via Nature Transformation, taking control of the desert climate and the sand itself.

Izayoi merely flicked his black sword.

A flash of white light—and the sandstorm, the lances, everything, vaporized into nothingness.

No familiar white slash filled the air. Just one instantaneous gleam and Kaguya's attack dissolved.

With several uses of the Sword of Nunoboko, Izayoi had grasped that purely mental power and begun playing new tricks. It was a credit both to his Transcendent Aptitude (Multi-Color) and to the Chakra Orb.

The Orb was a variant of the Sword of Nunoboko: both could create and erase worlds. The difference lay in imagination. If one's energy and creativity were boundless, the Orb could, in theory, create anything—even humans.

But to create people, Izayoi would need profound knowledge of the human body and mastery of Yin‑Yang Release. In principle, Yin‑Yang Release could fabricate mindless human shells or sentient chakra constructs; then, like Kaguya in the manga, he could create humankind or his own offspring.

The Orb relied on imagination, the Spears on will. Both were expressions of spirit—perhaps of soul.

Suddenly Izayoi understood why Hagoromo's soul had survived after his body died. And he was certain Hagoromo's power had not degraded in the least—only his Ten‑Tails‑level chakra volume had dropped. When people die, their chakra fades with the soul, but Hagoromo's current reserve matches his level at death. With his Yin‑Yang prowess, his soul‑state might even replenish chakra.

Compared with Madara and Kaguya, the old driver who had sealed his mother a second time and ended his sons' millennium‑long feud was the truly fearsome one. Izayoi still could not fathom why the Sage targeted him so persistently, nor why he had not struck when Izayoi was weaker.

But now was no time to ponder.

After nullifying the desert's power with a thought‑forged sword, Izayoi's black blade liquefied into a sphere then shot downward as a black beam, turning gold mid‑flight like a meteoric streak and burrowing into the sand. A tornado of sand then burst skyward—and amid the swirl floated a white‑haired woman, furious, yet untouched by the vortex.

"The link between my dimension and this space… has been severed!" Kaguya muttered in disbelief. Even Hagoromo had never achieved that. The months‑long battle of mother and sons millennia ago had dragged on only because Amenominaka and Nature Transformation let Kaguya slip peril countless times. Hagoromo could neutralize natural attacks, nothing more.

Yet this heir to Hagoromo's power had done what Hagoromo could not. Could he be related to the Sage? No—there was no sign of the Divine Tree on him, no aura of Hagoromo. He was neither reincarnation nor descendant.

Unwilling to accept it, Kaguya invoked Nature Transformation once more. Countless grains of sand became spears and arrows, flooding upward.

Izayoi lifted a hand—and another golden sphere formed.

At the sight, Kaguya panicked, instantly launching Amenominaka and vanishing from the Desert Space—unaware she had leapt straight into Izayoi's trap.

She arrived in the Lava Space, where a small metal tag hovered before her. Instinctively she blinked—then Izayoi's true body appeared. BOOM—

Izayoi had been watching the Lava Space through his Rinne‑Tenseigan. The instant Kaguya materialized, he warped the Flying Thunder God marker to her and swapped himself in. He thrust out a transparent golden pillar of light that pierced her.

Kaguya was frozen in midair, unable to move. More golden pillars lanced in from every direction, passing clean through her body.

Her form began to crumble.

Izayoi, who had followed from the Desert Space, immediately forged another golden sphere, siphoning the Ten‑Tails' chakra.

All jutsu have weaknesses; Amenominaka is no exception. It has a minute cooldown and costs chakra to use. With her insides and outsides wrecked by the light pillars, Kaguya could not focus her dōjutsu precisely. She could not even open Yomotsu Hirasaka; she could only watch Izayoi drain her.

Perhaps through inexperience—or sheer shock—she reacted too late. When she did, a black substance erupted from her body, forming a giant orb that encased her and blocked the beams. Then the orb vanished.

But every one of Kaguya's pocket dimensions now held Izayoi's wood clones—imperceptible even to the Byakugan. With the far‑seeing Rinne‑Tenseigan covering the entire world and beyond, he could lock precisely onto Kaguya, then use Heavenly Transfer Technique plus Flying Thunder God to appear before her in a heartbeat and unleash pre‑charged strikes.

Kaguya, accustomed to brute‑forcing everything and armed with nothing but immortality and Kekkei Mōra, had needed months to deal with two sons far weaker than herself. She simply could not adapt to modern tactical combat.

Having absorbed the vast chakra‑filled sphere, Izayoi's eyes flashed with surprise—then he chuckled. "Looks like the Ancestor of Chakra has been scared witless. All the better for me."

He opened Yomotsu Hirasaka and stepped back into the Genesis Sphere.

There, a white rabbit the size of a mountain was roaring like a beast. Ten white tails sprouted from its back. Its bellow made the dimension tremble; the green sky shifted colors. A sea of chakra streamed into the creature—though Izayoi had drained her massively, Kaguya's reserve was still a third greater than his and climbing rapidly.

Thunder rumbled. Each tail shimmered with a different light. Hurricanes and torrential rains raced toward Izayoi—yet within the winds and sheets of water one could see every element's hue. Lightning and floods manifested as well. The Core Dimension looked like doomsday itself.

This was Heaven and Earth Cataclysm—a cataclysm beyond even the Ten‑Tails.

Those multicolored forces were the seven nature transformations. The chakra pouring into the rabbit belonged to all the shinobi caught in Infinite Tsukuyomi, which Kaguya could draw at will in this space.

As the apocalyptic forces surged from every direction, Izayoi's expression finally grew solemn.
