The Variable

Blood dripped down Orochimaru's Haku arm, spreading into a small patch of dark Kurenai over the rotting leaves.

He could no longer remember the last time he had been injured.

Though such a wound was nothing to him, it still left him with the discomfort of biting into a fish bone during a meal.

"Heh heh..."

A low laugh, heavy with suppressed fury, rolled from deep within his throat.

"What a... tremendous surprise you've given me, Naruto-kun."

The way he looked at Naruto had completely changed.

It was no longer the appreciation one held for an intriguing new toy, but the scrutiny of one predator discovering an unknown species—and the wariness of a predator facing another predator it could not comprehend.

This brat's fighting style, his so-called theory of "purification," and that unheard-of vicious weapon...

Everything about him carried an eerie quality that did not belong in this world.

If he did not reveal more of his abilities, taking Sasuke Uchiha—the perfect vessel—without injury in a short amount of time would likely cost him dearly.

Orochimaru's left hand, hidden inside his sleeve, silently formed an extraordinarily subtle hand sign.

It was a signal.

A signal that only his most trusted pawn could understand.

In another battlefield several hundred meters away, Kabuto Yakushi, wearing round glasses, had just cleanly dispatched two Sound Ninja examinees who had tried to seize his scroll with a scalpel.

He adjusted his glasses, and his gaze beneath the lenses precisely caught Orochimaru's subtle movement in the distance.

"It seems Lord Orochimaru has run into some trouble."

He muttered softly, the corner of his mouth curling into a knowing smile.

"Uzumaki Naruto... he's becoming more and more interesting."

Kabuto Yakushi did not hesitate in the slightest. He took an utterly unremarkable scroll from his robes and casually slapped it against the tree trunk before him.

The scroll silently turned into a wisp of blue smoke and melted into the forest.

There was no violent fluctuation of chakra, nor were there any startling lights or sounds.

Yet the dampness that perpetually hung in the forest, mixed with the stench of rotting leaves and soil, seemed to grow heavier.

Even the movement of the air seemed to become thick and sluggish.

At the center of the battlefield.

Naruto remained in a guarded stance. The Shadow Clones around him formed an impregnable diamond-shaped defensive formation.

He could sense that Orochimaru's presence was still evil, but now it carried a trace of gravity.

"What's going on?"

Sasuke's voice suddenly rang out, carrying a strange note of confusion.

His Sharingan could clearly see the flow of chakra.

Just then, he had discovered an extremely faint, bizarre chakra spreading through the air—something invisible to the naked eye.

Like mist that seeped through every crack, it was silently enveloping the area.

"Naruto, the air..."

He wanted to warn him, but found that his tongue felt numb and refused to obey him.

Naruto noticed the abnormality almost at the same moment.

His body, tempered through countless battles, possessed an instinct for environmental changes that was nearly bestial.

The air entering his lungs carried a faint, strange sensation that numbed the nerves.

His combat style, which depended heavily on biological function, suffered an extremely brief moment of stagnation.

Bzzzz—

The roar of the Chainsword faltered ever so slightly.

Now!

"Are you all right?!"

A gentle yet anxious voice came from the woods behind them.

Kabuto Yakushi emerged from behind a clump of bushes, a Konoha forehead protector clearly visible on his brow.

His face held just the right amount of concern and urgency, like a Konoha comrade who had happened to pass by and come to offer aid.

"Get back! I'll hold them off for a while!"

As he shouted, he rushed toward Team 7. His movements appeared entirely harmless.

A flash of relieved joy even crossed Sakura's face.

Yet the instant he approached Naruto's defensive perimeter, his wrist flicked.

Several Senbon coated with the same neurotoxin shot silently toward Naruto's Shadow Clones at an exceptionally tricky angle.

This was not a fatal attack. Its purpose was merely to create confusion and an opening.

Naruto's Shadow Clones immediately swung their swords to block, but their numbed nerves made them a beat too slow.

Clang! Clang!

Amid the crisp collisions, two Shadow Clones created a fleeting gap in the formation as they moved to block the Senbon.

Orochimaru seized the opportunity.

A perfect opportunity created by his subordinate's cleverness.

"Snake Shedding Technique!"

His body, like a shed snakeskin, remained limply where it was and took Naruto's powerful blow head-on.

Yet his true body appeared at the gap in the formation in a manner impossible to understand.

His neck stretched grotesquely, as though it had no bones at all.

In an instant, it crossed more than ten meters and appeared before Naruto.

There was no ninjutsu.

Nor was there any bizarre technique.

There was only a tightly clenched fist, gathering the strength of his entire body, striking Naruto precisely and viciously against the left temple.

Thud!

A dull impact that made Kiba's teeth ache rang out.

For the first time, the light in Naruto's ice-blue eyes—eyes that always burned with the flames of judgment—shuddered violently before swiftly dimming.

The world before him abruptly went black.

The tremendous impact sent his rock-solid body falling backward beyond his control.

Boom.

Naruto's body crashed heavily onto the ground, kicking up a cloud of dust.

The constantly roaring Chainsword slipped from his loosened grip and crashed to the ground beside him with a clatter.

Its rapidly spinning chain let out an unwilling, piercing scrape before slowly coming to a stop, like a dead beast of steel.

Time seemed to freeze at that moment.

"Nar... uto?"

Sakura's trembling lips formed a broken, unsteady sound.

Sasuke's pupils contracted to their limits.

His spinning Sharingan stared fixedly at Naruto, lying motionless on the ground, as if trying to burn the sight permanently into his mind.

How... was that possible?

Naruto, who had been as powerful as a god and as unbreakable as steel...

Naruto, who had forcibly dragged him from the abyss of fear and pushed him to grow stronger in the cruelest possible way...

Had actually... fallen?

That realization was a hundred times, a thousand times more terrifying than Orochimaru himself.

It was the crushing sensation of the sky collapsing and the earth splitting apart.

Orochimaru did not even spare Naruto another glance.

He slowly retracted his elongated neck and turned around. His golden snake eyes locked once again onto Sasuke's rigid body.

A victor's teasing smile, like a cat toying with a mouse, hung on his face. He extended his long tongue again and greedily licked his lips.

"Now..."

His steps were slow, one after another, each one crushing Sasuke's shattered beliefs as he approached the prey that could no longer move.

"No one will interrupt us anymore, my dear Sasuke-kun."

Fear.

Boundless fear surged in from every direction like icy seawater, flooding Sasuke's mouth and nose and pouring into his lungs.

He wanted to pick up the Chainsword from the ground and fight like Naruto had—to tear apart the demon before him.

But his body was nailed in place by the neurotoxin and a deeper terror. He could not even move a finger.

He could only watch helplessly.

Watch Orochimaru's neck stretch grotesquely once more in defiance of all physical laws.

Watch that pale, demonic Haku face grow larger and larger in his vision.

Watch him open his mouth, exposing two rows of gleaming Haku Kiba teeth.

"Become mine."

"You will obtain everything you desire... power!"

The demon's whisper sounded beside his ear.

The next second.

Squelch!

Sharp Kiba fangs viciously pierced Sasuke's neck.

A cold chakra, evil beyond measure, surged madly into his body through the wound like the filthiest flood.

"Aaaahhhhhh—!"

A scream so agonized it no longer sounded human tore through the forest's dead silence.

The searing pain, accompanied by the sickening feeling of his soul being defiled, instantly destroyed Sasuke's last shred of will.

His body convulsed violently. At his neck, three black Tomoe markings emerged like living things, spun, and finally settled into place.

The light in Sasuke's eyes went out completely.

His body went limp and fell backward, sinking into boundless darkness.
