Kakashi didn't use the Body Flicker. At this velocity, standard displacement created a sonic boom that would rupture eardrums. He simply moved, pushing his muscles past the safety limits of the Eight Gates' first stage without opening it.
He was a blur of silver and flak-jacket green.
The low, western sun caught his plated headband, turning him into a streak of blinding white fire that severed the visual connection between the two boys.
The roof of the hospital was a kill box. To his left, the high-amperage scream of the Chidori—chirp-chirp-SCREE—shredded the ozone layer. To his right, the low-frequency grind of the Rasengan distorted the air like a jet engine at takeoff.
The smell of electricity was suffocating, tasting like copper pennies on the back of the tongue, clashing with the scent of singed hair and superheated dust.
Sasuke and Naruto were millseconds from mutual annihilation.
Kakashi inserted himself into the vector.
He didn't block. Blocking two S-rank energy signatures would incinerate his arms. He redirected.
His hands shot out, gripping their wrists with enough force to bruise bone.
"STOP IT!"
With a savage torque of his hips, Kakashi used their own forward momentum against them. He swung them wide, turning their collision course into a centrifugal throw.
Whump.
The air displaced by the throw snapped back into the vacuum with a sound like a cracking whip, popping the eardrums of everyone on the roof.
WHOOSH.
Naruto was launched to the left. Sasuke to the right.
They slammed into the massive, galvanized steel water towers that fed the hospital's fire suppression system.
CLANG-CRUNCH.
The impact was sickening. Metal buckled. Rivets popped like gunfire.
Then, the water came.
ROAR-SPLASH.
Thousands of gallons of pressurized, chemically treated water exploded from the ruptured tanks, flooding the roof in a knee-deep deluge.
The spray hung in the air, catching the heavy, late-afternoon light and turning into a curtain of liquid gold that briefly obscured the violence.
The water smelled of stale rust and industrial chlorine, a cold, chemical shock that instantly soaked through their clothes and plastered them to their skin.
The water was freezing, a sharp, violent contrast to the unseasonable warmth of the afternoon sun beating down on their necks.
"Motion Resistance... Engage!"
The voice was shrill, desperate.
Sylvie stood near the stairwell door, her hands forming the Ram seal. She didn't run from the flood; she weaponized it.
"Water Style: Stillwater Domain!"
Kakashi watched, his Sharingan tracking the chakra flow. It was ambitious. Too ambitious.
The rushing water instantly turned viscous. It didn't freeze; it thickened, behaving like non-Newtonian fluid. It gelled around Naruto, trying to smother the boiling red chakra of the Kyūbi. Simultaneously, it wrapped around Sasuke, trying to dampen the kinetic vibration of the Cursed Mark.
She was trying to hold a nuclear reactor and a lightning storm with the same pair of hands.
It worked for a second. The boys froze, suspended in the clear jelly.
But then, the physics rebelled.
On the left, the heat from Naruto's cloak flash-boiled the water, creating steam pockets that shattered the surface tension. On the right, the high-frequency oscillation of Sasuke's mark vibrated through the liquid, liquifying the gel instantly.
Sylvie screamed as the feedback hit her nervous system. She collapsed to her knees, nose bleeding, her dampening field shattering into harmless splashes.
A high-pitched whine erupted behind her eyes—eeeeeeee—as her chakra coils spasmed, sending a phantom sensation of burning needles down her fingertips.
She stretched too thin, Kakashi noted, his heart sinking. She tried to save them both, and so she held neither.
Sasuke ripped his arm free from the water. He didn't look at Sylvie. He didn't look at Neji, who was pulling himself out of a tangle of wet sheets by the HVAC unit.
Sasuke looked at the tanks.
He stood up, shaking the water from his hair. He looked at the dent his Chidori had made. It was impressive—a deep, scorched crater in the thick steel, the metal peeled back like a flower.
Then, he looked across the roof.
Naruto was slumped in the water, the red chakra receding. Behind him, the second water tank wasn't just dented.
The back of it was blown out completely.
A shaft of aggressive orange sunlight pierced straight through the jagged hole in the tank, acting as a natural spotlight that illuminated the sheer scale of the damage.
The metal jagged outward like a shrapnel wound, the steel twisted and screaming from the sheer rotational force that had passed through it like a ghost.
The Rasengan hadn't just hit the surface; the rotational torque had traveled through the water and the steel, detonating the rear of the tank in a massive, jagged exit wound.
Sasuke stared at the destruction. The realization hit him harder than the throw.
Inferiority.
"What... is that?" Sasuke whispered, his voice trembling. "What are you?"
Kakashi stepped between them, the water sloshing around his boots. The atmosphere on the roof dropped ten degrees. He wasn't the lazy pervert reading a book anymore. He was the ANBU Captain who had washed blood out of his hair for a decade.
The wind on the roof seemed to die instantly, strangled by the sheer density of his killing intent, leaving the air heavy and still as a grave.
"That's enough," Kakashi said. His voice was quiet, but it carried the weight of a tombstone.
The shadows of the drying bedsheets stretched impossibly long across the gravel, reaching toward them like grasping fingers as the sun began its final descent behind the village walls.
Sasuke whipped around, his eyes wild, the Cursed Mark receding but leaving his skin flushed and angry. "Why did you stop me, Kakashi?! He tried to kill me!"
"And you tried to kill him," Kakashi countered, stepping closer. "Chidori is not for family quarrels, Sasuke. It is a blade for assassination. You pointed it at a comrade."
"Comrade?" Sasuke spat the word. "They are weights! They drag me down! You don't understand... you don't know what it's like to lose everything!"
Sasuke pointed a shaking finger at Kakashi's chest.
"Maybe if I killed everyone you ever loved... maybe then you'd understand! Maybe then you'd see why I need power!"
The silence that followed was absolute. The wind through the drying sheets sounded like the rustle of ghosts.
Drip... drip... drip.
The only remaining sound was the water falling from the ruined tank, hitting the puddle below with a rhythmic, mocking consistency.
Sylvie looked up from the wet gravel, her eyes wide behind her fogged glasses. Neji froze. Naruto looked down at the water, the guilt heavy on his shoulders.
Kakashi didn't flinch. He didn't get angry. He just looked tired.
"Go ahead," Kakashi said softly.
Sasuke blinked. "?!"
"You can try," Kakashi continued, tilting his head to the side, his lone eye curving into a sad, hollow smile. "But it would be pointless."
He looked up at the sky, where the sun was bruising the horizon a deep, violent violet above the Hokage faces.
"Because everyone I ever loved... is already dead."
Sasuke froze. The malice in his posture evaporated, replaced by a sudden, jarring confusion.
"Obito," Kakashi listed the names like he was reading a grocery list. "Crushed by a rock. Rin. Killed by my own hand. Minato-sensei. Impaled protecting the village. My father... suicide."
Kakashi looked back down at Sasuke. The eye-smile was gone.
"I have been where you are, Sasuke. I have stood in the dark. And I am telling you, revenge doesn't make you whole. It just makes you dead."
He gestured to the others—to Sylvie, shivering in the cold water; to Naruto, clutching his arm; to Neji, leaning against the vent.
"You think you have nothing," Kakashi said. "But look around you. You have created new bonds. If you sever them... if you choose that path... you will truly have nothing."
Sasuke looked at them.
He saw Sylvie, who had tried to hold him. He saw her failure not as love, but as weakness. He saw Naruto, whose power eclipsed his own. He saw Neji, who had dismantled him with superior technique.
Sasuke stood with his back to the setting sun, his silhouette casting a long, dark void that stretched all the way across the wet roof to touch Naruto's feet.
Their faces blurred in his vision, the edges of their silhouettes warping as the heat from the Cursed Mark began to simmer at the base of his neck, turning the world into a tunnel of grey static.
Soft, the voice in his head whispered. They make you soft.
Sasuke turned away.
"I'm going home," he muttered.
He leaped onto the fence, balancing on the rail for a second—a black silhouette against the dying sun.
For a moment, he blocked out the glare completely, a hole in the world where the light couldn't reach.
Then he dropped over the edge, disappearing into the village.
Scuff.
The sound of his sandal pushing off the metal rail was quiet, barely a whisper, but it felt like the loudest thing that had happened all day.
Kakashi didn't chase him. You couldn't chase a man who was running from himself.
"Everyone," Kakashi sighed, pulling his headband back down over his eye. "Go home. We're done for today."
The water from the tanks continued to drip—plip-plip-plip—onto the concrete, counting down the seconds until the inevitable.
