Chapter 151: Anything Less Would Have Been Embarrassing
Soon after his morning meeting with Emi, while dawn was still clinging to the valley, Kimimaro slipped into his own routine.
Steam curled from a nearby hot spring, not far from the base, the water quiet and undisturbed.
He stood there for a time, letting the heat roll over him as the world slowly woke.
By now, he was sixteen.
Physically, he was already close to his peak, easily eighty percent of his adult potential realized.
The same was true of his experience and will, hardened through things most shinobi wouldn't face even across decades.
There was very little left in this world that could surprise him in simple ways.
He had already mastered the Shadow Clone Technique, and with it, easily found and consumed the overwhelming majority of written knowledge the world had to offer.
Scrolls, records, research notes, history.
His clones read, practiced, dissolved, and returned everything to him with perfect recall.
Information itself was no longer a bottleneck to his spiritual power.
What remained to be refined now was not knowledge, but baslien depth through time.
That was cultivated almost constantly through meditation, quiet, disciplined, unbroken.
He no longer needed excess motion to temper himself.
As for physical training, crude repetition had long been abandoned.
No endless pushups. No pointless strain.
His chakra control, sharpened to an extreme by his current vision, allowed something far more efficient.
Even in stillness, even during idle moments, his Byakugan remained open, and his body trained itself from within.
Muscle fibers aligned. Bones adapted.
Internal stress was applied exactly where it was needed, continuously, precisely.
It was deeper than conventional training.
Narrower. More specialized.
So, that was not his true focus anymore, either.
What he refined above all else now was the Tenseigan.
Its use came with a strict limit, a narrow window before recovery was required.
And Kimimaro wasted none of it.
Not a single day.
This morning was one such window.
As the Tenseigan first activated in him a while ago, something stirred again inside at that time, familiar and yet even sharper than before.
A bloodline response.
A kekkei genkai resonance.
Chakra pathways around his eyes flared to life, and the effect rippled downward, into flesh and soul alike.
Shikotsumyaku responded immediately.
Its evolution deepened, its structure refined.
Even the advanced All-Killing Ash Bones version of it shifted subtly, improving in ways he could feel rather than see.
It reminded him of the change that had occurred when he first acquired the Byakugan, when his entire system had reorganized itself around a higher order of perception, like that as well.
In the weeks since awakening the Tenseigan, he had already forged several new bloodline techniques from those changes alone, each sharper and more dangerous than the last, refined to serve both current expressions of his kekkei genkai.
And the most important part was this: the evolution was permanent.
Just like the first time, when he stole the Byakugan in Konoha a year earlier, the changes did not require constant activation to persist.
They were now part of him.
The Tenseigan did not need to remain active for its influence to reshape him.
What remained was its mastery.
Learning how to fuse his existing abilities with the Tenseigan's unique powers.
Learning how to wield those powers themselves.
Step by step.
Window by window.
He stood there in the rising steam, eyes open, chakra moving in quiet, terrifying precision, and continued refining himself.
He let a measured breath out and then allowed it to surface.
The world shifted.
The pale cyan light flooded his vision as the Tenseigan opened, invisible kind of veins branching cleanly around the eye, luminous and precise rather than violent.
Everything sharpened at once, distance losing meaning, chakra lines revealing themselves not as flows but as layered structures, pressure, intent, imbalance, all laid bare in overlapping clarity.
It didn't feel like sight alone.
It felt like authority, as if the world's systems had briefly acknowledged him and adjusted.
There was no frenzy to it, no intoxicating rush.
Just overwhelming, absolute awareness, restrained behind his will like a blade kept deliberately sheathed.
As the Tenseigan opened, a quiet realization surfaced alongside the light.
He was already a full year past the point where his previous self should have died.
In that other path, he would have withered away as Orochimaru's discarded minion, a tragic footnote carved into someone else's ambition.
A death certificate written into fate itself.
And yet here he was, already brushing against the edges of Six Paths power.
The thought barely stirred him.
If anything, it felt expected.
As a descendant of the Kaguya clan, an offshoot of Hamura's line with absurd latent potential, armed with a transmigrator's knowledge and nearly a decade of deliberate cultivation from childhood onward, anything less would have been an insult.
He hadn't cheated fate.
He had simply refused to accept the version of it that demanded he die quietly.
Truth-seeking orbs assembled behind Kimimaro's back, perfectly smooth, perfectly obedient.
Fine lines of luminous particles traced across his skin, like quiet veins of light beneath porcelain.
With every breath, the air bent.
Not violently. Not explosively.
It simply yielded.
As the Tenseigan stabilized, Kimimaro turned inward, cataloging the sensation with cold clarity.
The dōjutsu's nature was almost disappointingly straightforward.
That was its strength.
The Tenseigan didn't rely on exotic tricks or convoluted mechanics.
Its value lay in how overwhelming and stable it was.
The chakra it generated could be folded inward, elevating the body into a sustained chakra mode, or projected outward as a complete gravitational field.
That was why its gravity felt absolute.
Not directional like the Rinnegan's push and pull, not conditional, not momentary.
It didn't shove or attract.
It imposed.
The rest followed naturally.
Truth-seeking orbs, clean and obedient.
Gravitational constructs.
Wheel-type techniques, silver or gold, where rotation and force fused with the potency of truth-seeking orbs, creating pure annihilation, equally absolute as offense or defense.
No gimmicks.
No clever shortcuts.
Tenseigan Chakra Mode settled around him as naturally as breath, as if his body remembered something it had once been meant to be.
He released a shallow pulse.
Pebbles lifted. Hung. Trembled in place.
"So this is it," Kimimaro thought calmly.
"The perfected form of the Ōtsutsuki's ancestral dōjutsu."
The Byakugan had been an eye of conquest, supreme perception, total awareness, vision refined to dominate unknown worlds.
The Tenseigan preserved that versatility, but shifted its axis.
From seeing…
To acting.
Not perception, but effect.
Simple. Direct. Absolute.
He could feel the microscopic pressure particles radiating outward from his eyes, compressing space itself, bending the air without resistance.
"Efficient," he mused. "No discovery curve. No fine-tuning. No tactics. Just will, and reality complies."
His thoughts drifted further.
"Kaguya never displayed this openly," he reasoned, "because she lacked Hamura's lunar half when she revived."
Black Zetsu would have missed it entirely. Or ignored it.
But the logic was unavoidable.
If Hamura possessed the Tenseigan, evidenced by the colossal lunar mechanisms it once powered, then Kaguya must have wielded it as well.
She was the original Byakugan bearer.
Once she consumed the God Tree, her dōjutsu should have evolved naturally.
There was no reason for the Rinnegan to manifest unless the ancestral Byakugan had already crossed that threshold first.
Most likely, the planet's natural energy had been so dense, so violently abundant, that both evolutions erupted simultaneously.
After that moment, history thinned.
Power diluted.
The Tenseigan regressed into the weaker Byakugan, a shadow of its former self.
The Rinnegan fractured, its legacy splintering into the new Sharingan, unstable, specialized, obsessed with singular expressions.
The contrast made sense.
The Tenseigan was built for stability, versatility, and sustained dominance, the natural successor of an eye meant to rule environments.
The Rinnegan was different.
Not universal. Not simple.
A collection of asymmetric miracles.
Paths.
Authorities.
Each terrifying, each narrow.
Enormous power, but fragmented, conditional, and deeply individual.
Kimimaro let the chakra settle, deliberately throttling it down.
Power like this wasn't meant to be flaunted.
It was meant to be mastered.
He raised one hand, fingers spreading slightly as pale particles gathered along his arm, drawn there as if gravity itself had decided to listen.
"Tenseigan: Celestial Divide."
A razor-thin horizontal line formed before his palm, space compressing inward along its length. The air bent, folded, screamed without sound.
Then it released.
The repulsive plane tore forward in a clean, absolute sweep, not exploding, not scattering, but erasing resistance through sheer directional force.
Stone parted. Air split.
The line vanished only after it had finished deciding what existed in its path.
Kimimaro exhaled slowly.
There wasn't much novelty in the techniques themselves.
That was the nature of the Tenseigan.
Its power wasn't about creativity, but refinement.
Pressure, direction, scale.
He shifted his stance and let the same energy curve inward instead of outward.
A translucent dome snapped into existence around him, a shallow sphere of condensed repulsion that pushed everything away from its surface without violence or flare.
Simple. Efficient.
"Tenseigan: Celestial Mantle."
Pebbles skittered outward, never touching him.
Next, a few floating truth-seeking orbs stirred behind his back.
He guided only a few forward, careful, deliberate.
They reshaped at his will, in the air, flattening into miniature shields, thinning into blades, reforming into compact spheres again.
Small. Deceptively small.
He could not use more than that currently.
But each carried absolute authority.
There was no hesitation in their response to his intent.
Yin and Yang eventually flowed together naturally now, no separation, no conscious stitching.
After years of training Yin and Yang apart, then weaving them together through Chinoike frameworks and ritual disciplines, it finally clicked.
Not through effort.
Not through practice.
But the moment the Tenseigan awakened.
Only then did perfect, legendary Yin–Yang Release fully settle into him as something automatic, natural, inevitable.
With it layered on top of them as well, the orbs were no longer just destructive matter.
They were negation itself.
Elemental ninjutsu already unraveled the instant it touched them, as each orb was already carrying all five basic natures, a built-in counter to any elemental alignment thrown its way.
Chakra constructs collapsed into nothing.
Even techniques that regenerated endlessly found no foothold, their logic erased along with their form.
Bodies. Souls. Laws.
Only senjutsu theoretically resisted them.
Kimimaro knew exactly what they were capable of.
Entire nations could not withstand even a handful used recklessly.
So he didn't.
He kept their number minimal, their motion controlled, testing shapes, densities, and response times.
A blade that curved mid-swing.
A shield that absorbed and dissolved force instead of blocking it.
A compressed sphere that hummed with restrained annihilation.
His Tenseigan window was limited.
He would not waste it.
Eventually, more of the orbs drifted back into formation, hovering in quiet orbit behind him, as the real fatigue finally started creeping in.
Kimimaro then eased the pressure entirely soon, letting the last dark distortion bleed out of the air until the world snapped back into place.
This wasn't about spectacle.
It was about inevitability.
And this was only the beginning.
For today, though, it was enough of that.
He moved on to integration.
Not flashy displays, but refinement, stitching the Tenseigan into what he already was.
First came pressure.
External vectors, subtle but constant, bending space just enough to make opponents heavier, slower, easier to catch.
His Dead Bone Pulse hit cleaner under it, his body moving inside the Tenseigan Chakra Mode with sharper delivery, bones emerging faster, denser, guided rather than merely fired.
All-Killing Ash Bones responded even better.
Under the Tenseigan's gravity-like fields, shaping them stopped being crude projection and became control.
Trajectory, spread, timing, all adjustable mid-release. He could curve them, compress them, pull them back in tight arcs, or let them bloom outward.
The real breakthrough came when he pushed even further.
He broke the All-Killing Ash Bones down to the smallest viable particulate scale he could currently achieve, each refinement guided by Tenseigan vision and ever-tightening chakra control that grew finer by the day, then held the particles suspended within a pressure field instead of launching them outright.
A drifting storm.
Every 'particle' in the making was lethal.
Not instantly, not theatrically, but absolutely.
One speck was enough given time.
Hundreds from every direction turned time itself into the enemy.
There was no dodging it, only delaying the inevitable.
Kaguya Art: Thousand-Ash Extinction
A perfect fusion.
Exactly the kind of weapon he'd always envisioned.
He tried to expand it further.
His Tenseigan flickered.
Pressure collapsed.
The field unraveled.
The storm fell inert before it could truly bloom.
Kimimaro exhaled and shut the dōjutsu down, a dull ache settling behind his eyes.
Too much. Still too much.
But he was smiling.
His control sharpened with each passing day, even if he was currently confined to only a few minutes of clean, efficient use at a time.
Even so, as he learned to draw more out of less, his effective range and destructive potential continued to expand steadily every time. This wasn't a failure.
It was a clearly defined ceiling being pushed outward, bit by bit.
And once his body finally caught up, once the Sage Body amplification from Hashirama's cells was complete, this technique wouldn't merely be possible.
It would be sustainable.
Wider. Denser. Sustained.
For now, even touching it was enough.
He stood, bones settling back into place, chakra calming.
Efficiency mattered more than scale at this point.
And today, he had made real, silent progress again.
His main strength was not only his kekkei genkai, but also his restraint.
