The sky above the Amegakure interior didn't just rain; it wept a torrential, rhythmic downpour that felt like liquid lead hitting the earth. The water here was thick with the scent of stagnant marshes and the sharp, iron tang of blood that never quite washed away, even under the relentless deluge. For Kaito, every step through the shin-deep mud was a lesson in mechanical resistance and the cold reality of a body being rewritten by a foreign logic.
The objective loomed ahead: the Central Dam. It was a brutalist masterpiece of rusted iron and reinforced stone, a vital artery for the Rain's industrial machine. But today, it was a fuse. High-level explosive tags had been rigged throughout the structure, intended to turn the reservoir into a tidal wave that would drown the Konoha forward operating base and erase the "Leaf invasion" in a single, watery stroke.
Kaito moved at the center of a diamond formation. To his left, Jiraiya rode atop a medium-sized toad, his face set in a grim mask of focus that replaced his usual bravado. To his right, Orochimaru moved with a liquid, predatory efficiency, his yellow eyes scanning the rusted pipes for the slightest flicker of intent. Tsunade held the rear, her presence a steady, glowing anchor of medical chakra and raw, suppressed fury. Kagami Uchiha was the point, a shadow that seemed to flicker in and out of the rain itself.
"We're entering the 'Dead Zone'," Kagami's voice crackled through the low-level chakra signal. "The Rain's Suicide Squad is waiting on the main walkway. They don't intend to survive this. They only intend to detonate."
The Refined Soru
Kaito felt the Total Concentration Breathing vibrating in his chest, his lungs now accustomed to the "Refined" efficiency of his training. He closed his eyes for a microsecond, flaring his Observation Haki. The world turned into a monochrome web of vibrations. He felt the rhythmic drip of water off a rusted valve fifty meters above. He felt the skittering of swamp rats in the pipes. And then, he felt the jagged, cold spike of twelve distinct intents atop the dam.
"I'll handle the detonators," Kaito said, his voice a low rasp that cut through the roar of the storm.
"Kaito, wait!" Tsunade reached out, but he was already gone.
"Refined Soru!"
In the span of a single heartbeat, Kaito's legs kicked the muddy earth and the iron railings twenty times. The sheer explosive force launched him across the dam's walkway like a railgun slug. He didn't just move fast; he was silent, his body swaying through the air using the initial principles of Kamie to slip through the wind resistance.
He appeared in the center of the twelve zealots. They were Jonin-level Rain shinobi, their faces hidden behind gas masks, their hands already forming the final seals for the explosion.
Kaito didn't give them the chance to breathe. He pulled Slaughter Demon from his inventory, the jagged obsidian blade pulsing with a faint, violet light.
CLANG. SLICE. THUD.
In a blur of motion, Kaito struck. The obsidian edge, fueled by his Armament Haki, ignored their chakra-infused leather armor. He moved with the precision of a surgeon, his Observation Haki predicting every desperate counter-strike. Three zealots fell before they could even scream, their blood washed away by the rain before it could hit the metal floor.
The Water Prison
The leader of the squad—a man with a prosthetic iron arm and a jagged scar across his mask—roared in defiance. He didn't reach for a blade; he slammed his iron palm onto the dam's walkway.
"Water Style: Crushing Basin!"
The water beneath Kaito's feet surged upward, not as a wave, but as a high-pressure sphere. Kaito was caught mid-stride, the liquid wall slamming into him with the force of a falling building. The pressure was immense, enough to collapse the lungs of a normal seven-year-old in seconds.
Inside the sphere, Kaito's vision blurred. The water was swirling with a violent, centripetal force, intended to tear his limbs from their sockets.

Kaito didn't panic. Panic was a waste of oxygen, and oxygen was his only fuel. He took the deepest breath his hyper-developed lungs would allow, feeling the Total Concentration flare into an Overdrive state.
He gripped Slaughter Demon with both hands. He focused his "Will"—the raw, unadulterated essence of his desire to survive—into the obsidian blade until the metal turned a deep, light-swallowing pitch black.
The Spatial Snap
"Kaito!" Tsunade's voice was a sharp crack of desperation as she leaped onto the walkway, her fist cocked back to shatter the prison.
But Kaito was faster.
He struck the wall of the prison from the inside. Not with a swing, but with a thrust that occurred within the 0.00001-second window of absolute physical focus.
"Divergent... BLACK FLASH!"
The world didn't just go silent; it inverted. A flash of black, distorted lightning erupted from the tip of the dagger, accompanied by a sound that wasn't a "hit"—it was the sound of space itself snapping under the strain.
The high-pressure water didn't just splash; it vaporized instantly into a cloud of white steam. The spatial distortion caused a vacuum that pulled the remaining zealots inward before the resulting shockwave sent them spiraling off the edge of the dam like ragdolls.
The iron leader was sent flying into a massive ventilation pipe, his prosthetic arm twisting into scrap metal under the force of the delayed Divergent Fist wave that hit him a microsecond after the black lightning.
The Aftermath of the Ghost
Silence returned to the dam, save for the hiss of steam and the distant roar of the reservoir.
Kaito stood in the center of the walkway, his right arm hanging limp, his skin steaming slightly as the heat from the Overdrive dissipated. The violet glow of Slaughter Demon was faint now, the blade exhausted by the discharge of cursed energy.
The Sannin landed on the walkway beside him. Jiraiya looked at the shattered remains of the Rain's elite squad, then back at Kaito, his usual bravado replaced by a genuine, fearful awe. Orochimaru stepped closer, his yellow eyes tracking the way the air seemed to shimmer around Kaito's skin—the Roughness trait now so intense it was beginning to abrade the rain itself.
"The dam is secure," Kaito rasped, blood trickling from his nose.
Tsunade didn't say anything. She simply grabbed him, her hands glowing with a fierce, emerald light as she forced her chakra into his protesting cells. She could feel it—the way his body was no longer quite human, the way his muscles felt like braided steel wire, and the way his heart beat with the rhythmic, mechanical precision of an engine.
As the sun—a real, golden sun—finally broke through the permanent clouds of the Land of Rain for the first time in weeks, the Sannin looked at Kaito. They didn't see a student anymore. They didn't see a civilian.
They saw the Hollow Anomaly, the boy who had broken the world's rules just to breathe.

"Let's get him back to camp," Kagami said, his voice heavy with the realization that the boy he was training was already outgrowing the village that created him.
The Second War was turning, but the shadow Kaito cast was only getting longer.
