The collision between the Cloud and Mist fleets had turned the northern horizon into a graveyard of burning timber and steam, but the Hidden Mist was not so easily deterred. While the main armada was in shambles, the elite—the Seven Swordsmen of the Mist—had utilized the chaos to launch a secondary, high-speed strike.
Three sleek, obsidian-hulled cutters had bypassed the gravitational reef by riding the high-crests of the whirlpools. They hit the southern docks of Uzugakure with a jarring thud. Leading the charge was Zabuza Momochi, a young but lethal prodigy of the Mist, and Kushimaru Kuriarare, wielder of the Nuibari (the Sewing Needle).
Renju was occupied with Fuguki in the deep water, and Renza was holding the sky against the remaining Kumo airships. The defense of the docks fell to the disciples.
Kakashi (9) stood at the edge of the pier. Behind him, the repurposed Uzumaki warehouses—now housing the village's food supplies—were at risk. To his left, Inosuke (10) was already stripping off his outer tunic, his boar mask trembling as he scented the iron in the air.
"Inosuke, take the left flank. Don't let them pin you down. Use the ruins for cover," Kakashi commanded.
"Don't tell me what to do, Scarecrow! I'll shred them all!" Inosuke roared, diving into the shallow water to intercept a squad of Mist chunin.
Kushimaru flickered onto the dock, his long, thin blade glinting. He moved with a sickening, skeletal grace. "A six-year-old and a nine-year-old? The Leaf truly has fallen if this is what they consider a sovereign force."
He lunged at Shisui (6), the Nuibari whistling as it sought to thread the boy's throat.
Shisui didn't move until the blade was an inch from his eye. He engaged the Sub-Abyssal Mirage. Kushimaru felt his blade pass through resistance, but there was no blood. Shisui had displaced the air around his body, creating a vacuum pocket that refracted Kushimaru's aim.
Shisui appeared three feet to the right. He didn't use a sword; he used the Neural Snap. He touched the wire attached to the Nuibari, sending a pulse of chakra-frequency back up the line.
Kushimaru's hand spasmed, but he was a veteran. He yanked the wire, bringing Shisui into a collision course with a flurry of senbon needles.
On the main pier, Zabuza swung his decapitating carve-sword, the Kubikiribōchō. Kakashi parried with a short-sword, but the sheer physical mass of the Mist blade pushed him back.
"You're fast, kid," Zabuza grunted, his face half-hidden by bandages. "But you're too small for this world."
Kakashi realized the standard Chidori wouldn't work here. The salt spray in the air was too conductive; the "thousand birds" sound would give away his position in the thick fog Zabuza was creating. He needed something more concentrated—something that didn't just strike, but severed.
Kakashi closed his eyes. He stopped the wild discharge of the Voltage Gate and forced the electricity into a single, microscopic point on the edge of his palm. The sound died down. The birds stopped chirping. In their place was a single, high-pitched hum that vibrated the wood of the dock.
"Lightning Blade: Raikiri."
Kakashi lunged. He didn't run; he used a Voltage Burst to propel himself. He bypassed Zabuza's blade entirely. The Raikiri didn't just hit Zabuza's shoulder; it cut through the Mist-style water armor like a hot wire through wax.
Zabuza gasped as the high-frequency lightning cauterized his muscle instantly. He jumped back into the water to ground the remaining current, his eyes wide with genuine shock. "That... that wasn't a jutsu. That was a localized storm."
While Kakashi held Zabuza, Inosuke was causing carnage in the shallows. He wasn't fighting like a ninja; he was fighting like a predator.
He used Wind Release to extend the reach of his jagged blades. When a Mist assassin tried to use the Hidden Mist Technique to vanish, Inosuke simply stood still. His skin, sensitive to the smallest change in air pressure, told him exactly where the assassin was.
"Beast Breathing: Third Fang—Devour!"
Inosuke spun, his dual blades becoming a horizontal saw. He didn't just hit the assassin; he shredded through the man's reinforced flak jacket and the stone pillar behind him.
"Come on! Is that all the Mist has?! My Master hits harder than you!" Inosuke yelled, headbutting a Mist chunin so hard the man's mask shattered.
The docks were holding, but the sky suddenly turned a bruised orange. Renza had intercepted a Kumo "Thunder-Keg" airship above the village. The explosion rained fire down onto the sea.
From the water, Fuguki Suikazan surged back toward the docks, having momentarily escaped Renju's gravity well. He looked at his decimated vanguard and his wounded proteges.
"The boys are strong," Fuguki growled, the Samehada screeching as it smelled Kakashi's high-density chakra. "But they are still children. Samehada! Feast!"
Fuguki slammed the massive sword into the water, sending a wave of chakra-eating sharks toward the exhausted disciples.
"Back to back!" Kakashi ordered, his hand sparking with the remnants of the Raikiri. "Shisui, Inosuke—don't let the sword touch you. It eats chakra on contact!"
The three disciples formed a tight triangle on the burning pier. They were outnumbered, low on chakra, and facing one of the most dangerous swordsmen in history. But they didn't look back at the Kage building for help. They looked at the enemy.
"Sovereign ground," Shisui whispered, drawing his own blade. "No one takes it."
The southern docks were a landscape of splintered wood and rising steam. Kakashi, Shisui, and Inosuke stood their ground, but the physical toll was visible. Kakashi's breathing was ragged, the skin on his right palm charred from the heat of the Raikiri. Shisui's eyes were bloodshot from the strain of maintaining multiple mirages, and Inosuke was bleeding from several shallow cuts dealt by the Hidden Mist's hidden blades.
Fuguki Suikazan loomed over them, the Samehada pulsing with a sickly green light as it gorged on the residual chakra in the air. "You've fought well for children, but your masters are too far to save you now."
Fuguki raised the massive, bandaged blade for a final, crushing blow.
The air didn't just get cold; it became solid. Fuguki's downward swing didn't miss—it stopped. The Samehada let out a high-pitched shriek as an invisible force slammed it into the pier, pinning the sword and Fuguki's arms to the wood.
"I believe I told you," Renju's voice rumbled from the mist, "that you are not a guest."
Renju landed silently behind the disciples. His purple Sage markings were glowing with a violent intensity, and the air around him warped like a heat haze. To his left, Renza descended from the sky, his emerald aura trailing behind him like the tail of a comet.
"Move back," Renza commanded the disciples. His voice was a sharp whistle of wind. "You've held the door. Now we're locking it."
The Hidden Cloud airships that had survived Renza's initial assault began to regroup overhead, preparing a saturation bombardment of lightning-kegs. On the water, the remaining Kiri vessels turned their cannons toward the shore.
Renju and Renza didn't reach for their weapons. They stepped toward each other and clasped forearms.
"Sage Art: Dual-Gate Resonance."
The ground beneath the ruins of Uzugakure didn't just shake; it groaned as the tectonic plates shifted. Renju opened the Seventh Gate fully, channeling the Abyssal energy into the earth, while Renza unleashed the Gate of Wonder, pulling the atmospheric energy down from the clouds.
The friction between the two opposing Sage energies—the crushing downward force of the Abyss and the screaming upward vacuum of the Gale—created a phenomenon that the Great Nations had never witnessed.
"Sage Art: World-Ending Storm."
A massive, dome-shaped shockwave erupted from the center of the Estate. It didn't expand outward like an explosion; it imploded upward.
The Kumo airships were caught in the vacuum. Without air to provide lift, the massive vessels simply dropped from the sky, their hulls crumpling under the sudden, localized 10.0 Gs of gravity. On the sea, the Kiri ships were lifted out of the water by Renza's Gale energy, only to be smashed back down by Renju's Abyssal pressure.
The ocean around the Land of Whirlpools began to boil. A permanent, spinning wall of black clouds and violet lightning formed a five-mile ring around the island. The "Dead Water" zone had been upgraded. It was no longer a sensory trap; it was a geographical fortress that defied the laws of physics.
Fuguki, barely holding onto the Samehada, was thrown back into the churning sea. He realized then that the "Twin Sages" weren't just powerful shinobi—they were forces of nature that had claimed this island as their own domain.
While the Sages were occupied with the destruction of the two armadas, the "White Ghost" Obito (10) saw his opening.
He didn't use the water. He used the very ground the Sages were shifting. Under the cover of the violet lightning and the screaming winds, Obito utilized his Hashirama-enhanced Wood Release to burrow through the salt-crusted bedrock.
He emerged inside the Kage Building, his body smoking from the atmospheric friction. He stood in the center of the archive room, his three-tomoe Sharingan scanning the shelves for the Scroll of Seals.
"Searching for something?"
Saya (15) stood in the doorway. She hadn't been on the docks. She had been the last line of defense. Her dual blades were drawn, coated in a shimmering, dark poison.
"The Leaf wants its property back," Obito rasped, his wooden arm shifting into a serrated blade.
"This island doesn't belong to the Leaf," Saya replied, her eyes narrowing. "And neither does that scroll."
The two clashed in the narrow hallway. Obito's wood-release was erratic and violent, filling the room with jagged splinters, but Saya moved with Zero-Friction. She slipped through the gaps in his defense, her blades leaving thin, violet trails in the air.
She landed a strike on Obito's shoulder, the poison instantly beginning to blacken the white wood-flesh. Obito roared in pain, his Sharingan spinning wildly. He realized he couldn't hit her—she was too fast, moving in the "pockets" of pressure created by the Sages outside.
He slammed his hand into the floor, triggering a massive growth of roots to collapse the ceiling.
"If I can't have it, no one will!" Obito snarled.
As the building groaned, Obito used a high-speed Wood-Substituion to vanish into the shadows just as Renju's voice echoed through the structure. The White Ghost had failed his primary mission, but he had seen the heart of the Sovereign Estate.
The storm subsided, leaving the Whirlpool Sea in a state of unnatural calm. The Kumo and Kiri fleets were gone—either sunk, vaporized, or fled back to their respective borders.
Renju and Renza stood on the roof of the Kage Building, looking out at the new, permanent ring of black clouds that now encircled their home.
"They won't come back soon," Renza said, his green aura fading. "But they'll tell the world what they saw."
"Good," Renju replied. He looked down at his disciples—Kakashi, Shisui, Inosuke, and Saya—who were gathered in the courtyard. They were battered and exhausted, but they stood tall.
"The era of the 'Rogue Hatake' is over," Renju announced, his voice carrying through the ruins. "Today, the Sovereign Estate is born. Tomorrow, we begin the final refinement. We are no longer hiding. We are waiting."
