"How is that possible?!"
Ōtsutsuki Hagoromo stared in disbelief at the black lightsaber in Izayoi's hand.
The sword still followed the same principle as before: Chakra Orbs fused with the Sword of Nunoboko.
Even combined, however, this weapon's raw power was still well below the Sword of Nunoboko that Hagoromo himself wielded.
Izayoi had only recently grasped the sword's secrets; talent aside, without years of harsh training he could not yet reach Hagoromo's level.
For the past half‑month Izayoi had therefore avoided using the fused black sword at all. He relied instead on techniques such as the Eighty Gods Vacuum Attack, All‑Killing Ash Bones and other Kekkei Mōra, or on devastating ninjutsu born of Truth‑Seeking Balls and Chakra Orbs—always fighting at range, never letting Hagoromo close.
Yet now, after two weeks, Izayoi summoned the black sword again—and it shocked Hagoromo, because he sensed within it a power he knew only too well.
It was the power that appears when Yin‑Yang Release is honed to its summit, allowing one's very will to be condensed into a weapon: a purely ideational force—the power of miracles.
When cornered, humans can draw on this "impossible" strength. In Izayoi's former world it was called adrenaline; in the realm of anime it was "going berserk." The hero, against all odds, turns the tide.
That same "berserk" strength had once let Hagoromo—despite far poorer raw stats than his mother Kaguya—seal her away and even make Isshiki Ōtsutsuki hide in fear. When a warrior's faith itself becomes a weapon, the damage he causes is incalculable: one blow may spare a chicken, the next may shatter a world.
In ordinary hands such power is limited by human will; in the hands of an extra dimensional being it becomes the might to create or annihilate worlds—so long as the user's chakra can sustain it. Had he still been Ten‑Tails Jinchūriki, Hagoromo would have been omnipotent; now, lodging his soul in a descendant's body and borrowing chakra from the Pure Land, he was strong but not at his peak.
Yet the force he now felt from Izayoi rivaled that lost prime. It was as if he were seeing his younger self in a mirror.
A flash of insight struck him. Eyes wide, he whispered, "Could it be… your eyes do more than see the past and the future?"
"You guessed right—no prize, though," Izayoi grinned. "The moment you failed to one‑shot me, your fate was sealed. The stronger you are, the happier I become—you're gift‑wrapping power for me.
"I've mastered Sword of Nunoboko completely. Thanks to you and Hamura refining it, I'll show you what happens when the creative might of Chakra Orbs merges with the destructive might of Sword of Nunoboko!"
With a flick of his wrist the black sword slipped free.
"Shatter, void," he murmured.
The blade fragmented like glass hitting stone; each shard melted into the surrounding space and vanished.
Hagoromo's first instinct was to flee—but before he could move, his body split apart.
Jagged cracks—some white, some as dark as a Spacetime Maw—raced across his flesh and the very air around him.
"Spacetime Sever!"
At the name of the technique, both Hagoromo and the nearby dimension collapsed.
Spacetime energies that even the progenitor of chakra could not resist, together with a devouring force able to erase an entire dimension, tore him to pieces and consumed him. In a breath he was gone—body, spirit, everything.
Spacetime Sever was more than a spacetime cut; it was laced with Truth‑Seeking‑Ball power that erases all phenomena. Not only beings but the space they occupy fall to nothingness.
The shattered dimension drew in a new Spacetime Maw, its violent pull rattling the entire pocket world. Land masses floated, fissures multiplied, the Maw swelled.
Foreseeing this, Izayoi had escaped beforehand; at such close range the raging suction might have prevented him from using Amenominaka or Yomotsu Hirasaka to flee.
"What terrifying power—worse than any Kekkei Mōra," he muttered back in the real world, watching through a wood clone he'd left behind.
A week earlier he had secretly learned Hagoromo's spacetime‑interference method and the nature of "belief power" as a Yin‑Yang application. Mastery alone let him trade blows with Hagoromo, but a sure kill demanded a weapon stronger than Hagoromo's own sword. Without the Tenseigan—even with Ten‑Tails chakra and several of Kaguya's Kekkei Mōra—Izayoi could only draw, and likely lose, especially if Hagoromo managed to seal him with Six Paths: Chibaku Tensei.
He was grateful, again, that after rolling Uchiha blood skills he had dismantled them and stayed on the Tenseigan path. Hagoromo, with only the Rinnegan, lacked both Tenseigan and Chakra Orbs; he could never wield creative and destructive forces simultaneously.
Izayoi, possessed of a Kekkei Mōra‑level Tenseigan, could. His Unity of Polarities eclipsed the cumbersome rainbow sphere akin to the unstable Expansive Truth‑Seeking Ball.
Spacetime Sever, with no wind‑up—the instant the black blade shattered, space and everything in it died—was his true ultimate art.
Floating in the night sky, he spread the farsight and x‑ray vision of the Rinne‑Tenseigan like an invisible net across the entire ninja world. With Six Paths Sage Mode's senses, every life‑signal—moths under branches, animals untouched by Infinite Tsukuyomi—came into view. Humans trapped by the genjutsu, animals, even Edo‑Tensei spirits each had distinct signatures. If anyone else had escaped the illusion he would have seen them instantly—but Isshiki was nowhere in the realm.
Izayoi wasn't surprised; cautious Isshiki knew Infinite Tsukuyomi too well.
No matter—Izayoi had already gained the battle's greatest treasure. With ten Multi-Color tags he was now effectively the world's second progenitor of chakra, short only of Kaguya's reserves. Having slain the millennia‑old schemer Hagoromo and mastered Spacetime Sever, he feared none in Naruto or Boruto save perhaps the rumored transcendent Ōtsutsuki Shibai. In this world he was invincible. Clear the remaining clutter and one goal remained: surpass himself, break the limit of lifespan, and transcend reality itself.
Whoosh—
Beams of light appeared before him, visible only to him, ignoring distance and locking onto his body: tag‑beams. As they merged into him, system prompts echoed:
"Ding! You obtained the talent tag [God of Ninjutsu (Multi-Color)]. It overlaps with an existing tag—fuse or dismantle?"
"Ding! You obtained the talent tag [God of Sealing (Multi-Color)]. It overlaps with an existing tag—fuse or dismantle?"
…
Only two Multi-Color tags, no Rinnegan. Izayoi possessed only downgraded versions of them. Their potential was vast; they had surely helped Hagoromo invent countless incredible jutsu and seals capable of binding even the progenitor of chakra. Fused, they would make Izayoi the god of nin‑tai‑gen. Yet, after just a few seconds' thought, he said:
"Dismantle them all."
In an instant his points soared from five‑plus million to more than eight million.
"Profit." He chuckled and spent points to upgrade his purple "Ninjutsu Master" and "Sealing Master" to Multi-Color "God of Ninjutsu" and "God of Sealing."
The system was now his greatest cheat: dismantling a Multi-Color tag guaranteed seven‑digit points, yet upgrading any white tag to Multi-Color cost only 1,111,104. Unless dismantling yielded the bare minimum million, every Multi-Color tag he broke was at least a small win—and usually a huge one.
Thus the system had become his personal Divine Tree, while bearers of Multi-Color tags were rich "planets." Explode their tags into points, and he could keep turning trash tags into Multi-Color, climbing ever farther into extra dimensional power. Should tags upgrade beyond Multi-Color, he would outpace even Ōtsutsuki Shibai's unknown transcendence.
Compared with Chakra Fruits and pills, this was Izayoi's true path of evolution. Combining both methods, within a few years he would surpass pill‑empowered Isshiki and any pure‑blood Ōtsutsuki yet to arrive.
