"Ding! You've acquired the talent entry [Kekkei Mōra : Natural Integration (Multi-Color)]. Fuse or Disassemble?"
…
Half a year later.
Inside a certain pocket‑dimension of the space‑time tunnel, a colossal meteor floated in mid‑air. Its terrifying gravity kept rending the ground below, tearing up chunks of earth large and small, crushing them, then fusing the debris back onto its surface to enlarge the meteor still further.
Suddenly, a multicolored beam burst from the core of the meteor, ignoring every obstacle in its path. It streaked out like a shooting star and plunged straight into Izayoi, who hovered a short distance away, completely unaffected by the meteor's pull.
A rapid series of booming notification chimes erupted in Izayoi's mind.
Because of what those chimes announced, the sound was pure music to his ears.
"That took some doing… but it finally dropped."
With a soft sigh, Izayoi made his choice without hesitation:
"Fuse!"
The next instant, a new Multi-Color entry appeared in the "talent" column of his personal status panel.
From this moment on, Izayoi possessed the divine power to merge with nature itself—and to command it.
Thanks to Miketsu and half a year of watching Ōtsutsuki Kaguya use Natural Integration time and again, Izayoi mastered the ability in short order.
He invoked Amenominaka, shifting from that pocket‑dimension into an "acid world," then sank directly into the corrosive fluid.
At once, green, mist‑wreathed currents surged like a tsunami. They shot skyward like the Knock‑Up Stream from the pirate world, then coalesced into roaring water dragons.
Not only the tangible acid, but even the invisible corrosive force itself now lay within Izayoi's control.
Moments later he appeared in a realm of ice and snow. The visible frozen landscape—and the invisible frigid air—were likewise subject to his will.
With Natural Integration active, he was like a god of nature, the absolute master of the pocket‑dimension. Everything in the environment was an extension of his own body.
Kaguya had lacked real combat experience and had never truly become one with nature, so Izayoi could still pinpoint her original form via Tensonari.
Otherwise, she could simply have disappeared into nature itself and rendered pursuit impossible.
After repeatedly testing the new ability, Izayoi did not return to Kaguya's sealed space. Instead, he left the pocket‑dimension, re‑entered the real world, and teleport‑jumped to the ruins of Rōran where the God Tree was planted to begin an experiment.
To avoid accidents, he did not act in person. He created a wooden clone and had that clone attempt Natural Integration in hopes of fusing with the God Tree.
It failed—exactly as he expected.
The God Tree can bear chakra fruit and grant massive Kekkei Mōra powers to anyone who eats them. If it has not yet begun drawing on the planet's energy, it can still be damaged by Grand‑Techniques or Bloodline‑level attacks—perhaps even sliced by a Multi‑Rasengan‑Shuriken. But that's all.
As long as the planet lives, the God Tree cannot die.
No matter how many times it is felled or destroyed, it regrows.
Once it starts absorbing planetary energy, no method except space‑time abilities can harm or destroy it—a fact Izayoi had tested himself. Any damage heals instantly, because the tree is now bound to the planet. Unless one possesses world‑busting power, there is no way to interrupt its absorption.
Natural Integration is probably a vastly weakened offshoot of the God Tree's own ability. As a subordinate power, it has no effect on its superior.
So Izayoi was not surprised that fusion failed; he had only wanted to test it.
Seeing the ability was useless on the tree, he liquefied the surrounding ground and slowly shifted the God Tree until it stood right beside the entrance to the Dragon Vein cavern.
Instantly, the tree's absorption rate and output skyrocketed.
Next, Izayoi used Wood Release to grow a vast network of roots underground. Because the chakra source was the same, the roots linked successfully with the God Tree.
Other roots stretched toward the Dragon Vein's maw, writhing like tentacles and poking through the well walls.
"Miketsu!"
Each root‑tip transformed into a miniature black hole, unleashing a terrifying pull that gulped down Dragon Vein energy.
This energy is orders of magnitude more violent than natural energy; even a Sage‑physique would suffer grievously if they inhaled it. Izayoi's wood clone—Six Paths‑class though it was—began cracking all over within seconds.
Even Izayoi's true body, Multi-Color‑tier Self‑Regeneration notwithstanding, would likely last less than an hour before sustaining injuries beyond even that power's ability to heal. His very soul might be at risk.
Yet once he became one with nature, the Dragon Vein's aggression was swallowed by the natural world. The force could no longer shatter the earth; instead it rippled harmlessly through the liquefied ground.
The now‑tamed energy flowed along countless branches straight into the God Tree.
Ordinarily, the tree's roots draw energy only slowly—even when embedded near the Dragon Vein. They simply gather purer, denser energy there. But Izayoi's Wood Release + Miketsu acted like a giant syringe, pumping a continuous stream of "nutrient fluid" into the tree, vastly accelerating its growth and fruiting.
His only costs were Miketsu ocular power and the chakra for Wood Release and Natural Integration—trifles to Izayoi.
After a while, he canceled both techniques.
Having proved that Natural Integration lets him absorb Dragon Vein energy safely, he left the ongoing support work to his tireless labor force of wood clones—hundreds, even thousands of them.
With that army accelerating it, the God Tree—already rooted at the Dragon Vein's throat—would bear fruit at a staggering pace.
Once the "speed‑up crew" was in place, Izayoi used Yomotsu Hirasaka to return to the pocket‑dimension where Ōtsutsuki Kaguya was sealed.
The giant meteor was now completely under his control: cratered and still crumbling, constantly shedding stones that drifted up and welded themselves to its surface like tiny moons.
Inside, Kaguya had again fallen into deep slumber—she had merely changed beds.
Izayoi floated before the meteor, pressed one palm to the rock, and activated Natural Integration. His hand sank into the stone. Wood‑Release roots snaked to the meteor's core, wrapped around the comatose Kaguya, and Yura‑otsu flared once more.
A few minutes later he withdrew his hand.
In his palm swirled a tiny black hole—like a handheld Universal Pull. When it slowly winked out, several red pills remained.
They expanded like inflating balloons, quickly becoming four crimson fruits that hovered weightlessly above his palm.
These fruits were Chakra Edible Creations—refined from the God‑Tree chakra still circulating inside Ōtsutsuki Kaguya.
