Speedrunning Naruto to the Top

Without the slightest hesitation, Izayoi manipulated the surrounding Truth‑Seeking Balls, liquefying them into a huge black sphere that wrapped tightly around him.

In the next instant, a cascade of multicoloured calamities engulfed the sphere.

Lightning that shimmered like rainbows struck the orb again and again.

Gales and torrents glowing with the same prismatic light slammed into it from every direction.

Although the sphere—crafted from nine Truth‑Seeking Balls—boasted staggering defensive power, cracks soon spider‑webbed across its surface.

Clearly, every "natural disaster" assaulting it was either a Kekkei Genkai technique or a jutsu on the same exalted tier as the Truth‑Seeking Balls: top‑class ninjutsu with an absurd cost‑to‑power ratio.

While Izayoi was pinned down, Kaguya, now half‑submerged in floodwaters and transformed into a massive white rabbit, opened her mouth wide. She condensed a rainbow‑coloured sphere of energy—identical in hue to the disasters overhead—and swallowed it whole.

Just as a partially transformed jinchūriki can fire a Tailed Beast Ball as a beam of light, the white rabbit needed barely two seconds before its jaws parted again. A colossal rainbow beam shot skyward toward the cracked black sphere.

"Fool!"

Inside the sphere, Izayoi allowed himself a scornful smile.

Kaguya had already been naïve enough in her human form; now, as a white rabbit, her battle power had soared, but she seemed to have regressed to a beast's mindless instincts.

Instead of gathering chakra to form another Truth‑Seeker staff or Spear and meeting the attack head‑on, Izayoi poured chakra into repairing the cracks, buying the sphere a little more time. At the same moment his golden Rinne‑Tenseigan flashed, unleashing Yomotsu Hirasaka at full power.

A vast black portal snapped open outside the sphere.

Simultaneously, a slender rift appeared above the white rabbit's head—so unobtrusive amid the multicoloured chaos that it was almost invisible.

Yet none of those annihilating forces could so much as shake the rift.

The rainbow beam entered the first portal with perfect accuracy and burst out of the rift above the rabbit, plummeting straight down onto its body—all within three seconds. Even the rabbit's bestial reflexes failed to react.

Boom—

Brilliant, almost ethereal rainbow light blossomed across the ground of the Core Dimension, matching the surrounding catastrophes so perfectly that the scene might have been mistaken for a wondrous dreamscape: a sky shifting colours every second, rainbow radiance everywhere, a fairy‑tale world.

Anyone else would have found it breathtaking—right up to the moment their senses registered the killing intent and they were erased without even time to scream.

This realm was terrifying.

Even Truth‑Seeking Balls, capable of erasing all things, could maintain their form only briefly here before cracking.

That the dimension itself had not collapsed under such apocalyptic phenomena was the truly astonishing part.

As the rainbow light faded, the disasters gradually ebbed away. The previously raging space finally fell silent.

On the scarlet, crack‑marred ground lay a quivering white mass of viscous flesh—a heap of sludge that had once been Kaguya in her rabbit form.

The black sphere dissolved back into nine Truth‑Seeking Balls orbiting Izayoi. He gathered golden chakra into a sphere and began siphoning the Ten‑Tails chakra from Kaguya at a distance.

Streams of rainbow‑coloured chakra flames tore free of the fleshy mound, racing toward the golden orb, yet none could alter its hue.

Sensing her power being drained, the white rabbit's twitching grew frantic.

A thunderous rumble shook the entire dimension; countless fissures split open, and tree‑thick branches the size of small mountains erupted from the earth, not targeting Izayoi specifically but lashing out in every direction like a nest of serpents.

The scarlet plain turned instantly into a sprawling green continent—except that each towering branch, swaying like an octopus tentacle, sliced the air with ear‑splitting booms, as if entire mountains were swinging overhead.

Each of these branches dwarfed the hands of Sage Art Wood Release: True Several Thousand Hands; beside them, Tailed Beasts were infants before giants. A casual swipe could bat a beast who knew how far.

And every branch overflowed with chakra so dense that even a Truth‑Seeker self‑detonation might not annihilate them all.

As though glimpsing a fragment of the future, Izayoi did not waste chakra defending. He recalled the draining sphere, opened another Yomotsu Hirasaka portal, and slipped through, letting the indiscriminate branches strike empty air.

Moments later, the once‑green sky split with a new black fissure. Unlike earlier portals, this tear did not stabilise but stretched into an endless abyss.

From its yawning maw poured a misty green torrent—like a dam bursting—crashing downward.

The instant the liquid touched the tree sea it hissed violently. Branches tough enough to snatch and hurl Tailed Beast Bombs, resistant even to Truth‑Seeking explosions, corroded at a speed visible to the naked eye.

The floodwater came from Kaguya's Acid Sea dimension within Amenominaka—acid far stronger than any earthly vitriol.

Splashed with metric tons of the green deluge, the battered white rabbit—still unable to regenerate fully—was submerged. A deafening roar rose from the depths of the tree sea.

"That should be enough."

Izayoi stepped back through a portal, his golden Rinne‑Tenseigan piercing wood and acid alike, staring straight at Kaguya's core.

Her chakra was no longer surging; either she had finished absorbing all of the world's chakra, or the process demanded full concentration—something she could no longer spare.

Either way, Izayoi no longer cared.

Having siphoned Ten‑Tails chakra from both Madara and Kaguya multiple times, and fought with strict economy, his own reserves now nearly matched hers.

Five black portals blossomed around him. From each emerged a wooden clone in Six Paths Sage Mode, complete with nine Truth‑Seeking Balls.

"Golden Wheel Reincarnation Explosion!"

The clones instantly forged nine golden chakra spheres apiece, merged each with a Truth‑Seeking Orb, and spun them into shining wheels. Five titanic golden beams lanced down into the forest.

No deafening blast followed—only the crisp snick‑snick‑snick of relentless cutting.

Branches harder than diamond and vaster than mountains parted like tissue. The beams cleaved the green land into slabs and sliced the rabbit below into pieces.

Since awakening the Rinne‑Tenseigan, Izayoi's Golden Wheel had become a Kekkei Mōra technique, bolstered still further by Amenominaka's spear. Even barriers of countless Truth‑Seeking Balls would fare no better than Naruto's black rods did before Madara's Sage Art: Storm Release Light Fang.

Two years earlier, this move had been Izayoi's trump card, letting him defeat Six Paths Madara without entering Six Paths Sage Mode himself.

Yet against Kaguya in full Tailed Beast form, it barely counted as an inconvenience; like any jinchūriki of the Ten‑Tails, she could shrug off being bisected by paying a bit of chakra.

Izayoi knew that unless he could drain her chakra immediately after wounding her, even ten days and nights of such attacks would do little more than entertain her.

This time, instead of seizing the opportunity to absorb chakra, Izayoi raised one hand and formed a simple blue Rasengan.

Because all the chakra in his body already contained natural energy, this was a Sage Art: Rasengan—yet still classed only as an A‑rank technique.

He poured in more chakra.

The fist‑sized sphere swelled to basketball size. Inside it, ten Rasengan of the original size formed, each a different colour—representing the chakra and attributes of the nine Tailed Beasts and the Ten‑Tails itself.

He lifted his other hand and conjured nine golden chakra spheres—the Tenseigan chakra Balls—and slipped them, along with his nine Truth‑Seeking Balls, into the giant Rasengan.

Twelve fist‑sized spheres—each distinct in colour—spun clockwise inside the larger orb, then, driven by its vortex, whirled at random in a blur of multicoloured after‑images. One sphere collided with another; chain reactions followed; the pale‑blue exterior flashed through a kaleidoscope of hues.

Reflections of every colour danced in Izayoi's Rinne‑Tenseigan.

Seeing all he needed, he flipped his palm and tossed the sphere downward, then opened a Yomotsu Hirasaka portal and left the Core Dimension.

His five wooden clones kept the golden beams roaring, denying the rabbit—now suffering backlash from merging with the Ten‑Tails while grievously wounded and drained—any chance to revert to Kaguya's form and flee with Amenominaka.

The sphere flashed through twelve colours in succession, settling at last into a five‑coloured rainbow.

It slipped between the tangled branches and vanished into the tree sea.

Hum—

No earth‑shaking detonation followed. Instead, a brilliant white light—akin to Infinite Tsukuyomi turning night to day—blossomed from within the forest, expanding outward. As it spread, the white light took on rainbow tints.

In a single instant, the five wooden clones, the massive golden beams capable of cleaving the moon, the entire forest of indestructible branches, and the rabbit itself—all dissolved into nothingness.

The Core Dimension became a realm of pure rainbow light; nothing else existed within.

Floating in the corridor of space‑time, Izayoi watched the twisted gateway that represented the dimension, waiting to see whether it would vanish—for if it did, the Cote Dimension would have been erased.

Soon, the result revealed itself.
