The air in the Land of Rain did not feel like air. It felt like wet wool, thick with the scent of pine resin and the iron-tang of distant slaughter.
Renza crouched in the hollow of a rotted cedar tree, his lungs whistling. He was nine years old, and for the last forty-eight hours, he had existed in a state of perpetual "Micro-Bursts." His snow-white hair was a mess of grease and dried mud, and his grey eyes were bloodshot, the pupils dilated from the constant intake of adrenaline.
"Status," Jonin Kaji rasped. The scarred veteran was leaning against a stone outcropping, his single eye fixed on the mist-choked valley below.
"Kiba lost the scent half a mile back," Karin Inuzuka whispered, her voice trembling. Her ninken was tucked under her arm, shivering. "The rain... it's washing everything away. It's not natural rain, Sensei. There's chakra in the droplets."
"Hidden Rain scouts," Taiga whimpered, clutching his mace. "We should fall back to the main line."
"Fall back where?" Kaji growled. "We are the line."
Suddenly, the mist didn't just move—it parted.
A single figure stood fifty yards away. He wore the flak jacket of the Hidden Stone, but it wasn't the standard tan. It was reinforced with dark iron plates. He didn't carry a kunai; he carried a heavy, broad-bladed cleaver.
"Genin," the man said. His voice wasn't loud, but it carried through the rain with the weight of a falling mountain. "And a one-armed Jonin. A pity."
"Go," Kaji commanded, his voice dropping an octave. "Now!"
Two figures blurred out from behind the Stone leader. They were Chunin. In the Academy, a Chunin was a goal. In the field, a Chunin was a nightmare.
They moved at a speed that defied Renza's vision. One moment they were fifty feet away; the next, they were in the center of the squad.
Taiga swung his mace. It was a powerful, heavy strike that could crush a boulder. But to a Chunin, it was slow motion. The Stone ninja simply stepped inside the arc, caught Taiga's wrist, and snapped it like a dry twig.
"ARGH!" Taiga's scream was cut short as a knee slammed into his chin, launching him backward.
"Taiga!" Karin lunged, but the second Chunin was already there. He didn't use a jutsu. He used a Body Flicker so precise it left an afterimage. He appeared behind her and drove a kunai into her shoulder, pinning her to a tree.
Renza's vision narrowed. Breath. I need to breathe.
"Total Concentration: Burst!"
Renza exploded forward. His speed tripled. He reached the first Chunin in a heartbeat, his twin tantōs crossing in a "Dust Whirlwind."
The Chunin's eyes widened slightly. "Fast for a brat."
The man didn't panic. He drew a short-sword and parried. CLANG. The vibration nearly shattered Renza's teeth. The Chunin didn't just block; he redirected the momentum, using Renza's own speed to throw him into the mud.
Renza rolled, gasping. I'm at my limit. Ten seconds. I need more.
-----------------------------
The man with the iron-plated jacket—the Elite Chunin—stepped forward. He wasn't even breathing hard. He looked at Renza like a scientist looking at an insect.
"You have a strange rhythm, boy," the man said. "No hand signs. You're forcing your circulatory system, But your heart... it's too small. It's rattling in your chest like a stone in a tin can."
Shut up!" Renza roared.
He didn't just take a breath. He tore the air into his lungs. He ignored the stinging sensation of his capillaries bursting in his chest. He pushed past the 10-second safety limit. 12 seconds. 15 seconds.
"Wind Breathing, Second Form: Claws of the Purifying Wind!"
Renza became a whirlwind of white and silver. He struck twelve times in three seconds. Each strike carried enough force to decapitate a bull.
The Elite Chunin didn't move his feet. He used his cleaver like a shield, catching every single strike on the flat of the blade. Ting-ting-ting-ting! "Is that it?" the Stone ninja asked.
He swung his cleaver. It wasn't a fast strike. It was a heavy one.
Renza crossed his blades to block. When the metal met, Renza felt his collarbones groan. The sheer physical power of an Elite Chunin—the result of years of chakra-reinforced muscle growth—was a wall he couldn't climb. He was blown backward twenty feet, his boots furrowing the mud.
Renza coughed. A spray of bright, arterial blood hit the ground. He had pushed his lungs too far. The "Glass Ceiling" had shattered, but it was his own body that was breaking.
"Enough," Kaji said.
The one-armed Jonin stepped in front of Renza. His aura changed. It wasn't a "vibe" or a "feeling"—it was a physical pressure that made the rain bend away from him. This was the Jonin level.
The Elite Chunin from the Stone finally stopped smiling. He dropped into a kill-stance.
"Kaji of the Iron Arm," the Stone ninja spat. "I thought you died in the first skirmish."
"I'm hard to kill," Kaji replied.
Kaji moved. There was no "speed." There was only presence and then result.
One moment he was standing; the next, the entire clearing was shredded. Kaji didn't use a flashy jutsu. He used a Great Wind Breach. He exhaled a single lungful of chakra-infused air that carried the force of a hurricane.
The two regular Chunin were caught in the blast. Their clothes were shredded, their skin flayed by the sheer pressure of the air. They were launched through trees like ragdolls.
The Elite Chunin managed to plant his cleaver in the dirt to anchor himself, but even he was coughing blood from the sheer concussive force of a Jonin's "casual" attack.
"Renza," Kaji said, not looking back. "Grab the girl and the boy. Run."
"But Sensei—"
"RUN!" Kaji roared. "A Jonin fight isn't a duel! It's an environmental collapse! You stay here, and the shockwaves alone will liquefy your organs!"
Renza looked at Kaji. The man's chakra was flaring so bright it was visible to the naked eye—a roiling blue flame that defied the rain. Across from him, the Stone leader began to weave hand signs at a speed that looked like a blur.
"Earth Release: Mountain Crushing!"
The very ground beneath them rose up like a titan's jaw.
Renza grabbed Taiga's collar and hauled Karin onto his shoulder. He took one last, desperate breath—not for power, but for survival.
As he fled into the trees, he heard the sound of the world tearing apart behind him. Trees were snapping like toothpicks. The earth was groaning.
He realized then the terrifying truth of the Ninja World.
He and Renju weren't "monsters." They weren't "prodigies." They were ants playing in the footsteps of giants.
Renza ran until his lungs felt like they were filled with broken glass. He ran until the sound of the Jonin battle faded into a dull, terrifying thrum in the distance. He collapsed in a muddy ditch, his heart skipping beats, his vision fading to black.
I need to be stronger, Renza thought as his consciousness slipped away. I need to breathe... until the world... stops.
