The katana hit the dirt, kicking up a small cloud of dry dust. The polished steel caught the harsh morning sun, glaring sharply into Zoro's eyes.
Zoro stared at the weapon. His chest heaved violently, pulling in desperate, ragged gasps of air. Blood from his torn blisters dripped slowly down his fingers, soaking into his white bandages.
Master Kenji stood ten feet away. The dark combat gi seemed to swallow the light around him. The wooden cane he always leaned on was nowhere to be seen. His posture was perfectly straight, his own katana resting casually in his right hand.
"Pick it up."
Kenji's voice wasn't loud, but it carried a deadly absolute.
Zoro unlatched the heavy canvas bag, letting it crash to the ground. He uncurled his stiff, aching fingers from the iron beast, letting the heavy tungsten slab fall with a heavy thud. He knelt, his legs trembling from the agonizing run, and wrapped his bleeding hand around the real katana's hilt.
He stood up.
The sword felt terrifyingly light. After carrying hundreds of pounds of iron and sand all night, Zoro's brain miscalculated the force needed to move a standard three-pound blade. He raised the katana, but his arm jerked upward too fast, his muscles misfiring. He stumbled slightly, his balance entirely thrown off.
Kenji didn't wait for him to recover.
The old man crossed the courtyard in a single breath. There was no traditional bow. No warning. Just a terrifying, fluid grace that betrayed his old age.
A flash of silver aimed directly at Zoro's chest.
Zoro gritted his teeth, forcing his screaming body to obey. He brought his blade up in a desperate block.
CLANG.
Sparks exploded as live steel met live steel. The impact sent a violent shockwave down Zoro's arm. His weakened grip faltered. Kenji twisted his wrists with brutal efficiency, sliding his blade straight down Zoro's guard.
The razor-sharp edge sliced cleanly through the fabric of Zoro's shirt, drawing a thin, hot line of blood across his collarbone.
Zoro stepped back, his eyes widening. The sting was sharp. This wasn't a wooden practice sword. One wrong move, and he would lose an arm. Or his life.
Kenji leveled his sword, his face utterly blank. "You are slow. Your muscles are confused. Your grip is weak. If I were a villain, you would be dead on the ground right now."
Zoro wiped a mixture of sweat and dirt from his chin. A dark, dangerous grin slowly crept across his face. The exhaustion was still there, but the adrenaline of real danger ignited something feral in his blood.
"Good." Zoro shifted his stance, lowering his center of gravity. "A wooden stick wasn't going to cut it anymore anyway."
He charged.
Zoro swung horizontally. It was a raw, brutal strike, fueled entirely by instinct and anger.
Kenji parried effortlessly. He sidestepped the heavy blow and flicked his wrist, striking Zoro's ribs with the blunt spine of his blade. The impact cracked loudly in the quiet courtyard.
Zoro stumbled, all the air leaving his lungs, but he didn't fall. He pivoted on his heel, using the momentum of his own stumble to launch a ferocious downward slash.
Kenji deflected it, but his gray eyes widened a fraction of an inch. The sheer physical force behind the exhausted boy's swing pushed the old master back half a step. His boots dragged in the dirt.
Zoro's breathing turned into harsh rasps. His vision tunneled. He didn't have the stamina for a drawn-out fight. His body was already operating on borrowed time. He needed to end this immediately.
He reached toward his left hip, his fingers stretching toward the hilt of his second sword.
Kenji saw the muscle shift in Zoro's shoulder. The old master's stance changed instantly.
"No."
Kenji's blade became an absolute blur. Before Zoro's fingers could even touch the second hilt, a sharp, precise pain erupted in his left wrist. Kenji didn't cut him; he struck the exact nerve cluster with the flat of the blade.
Zoro's left hand went entirely numb, falling uselessly to his side.
Kenji pressed his advantage immediately, stepping inside Zoro's guard. The cold, sharp edge of the katana pressed gently against the pulse at Zoro's neck. A single drop of blood welled up where the steel touched the skin.
"You rely too much on brute force to cover your fatigue," Kenji stated flatly, his breathing perfectly steady. "In a real fight, a tired muscle is a dead muscle. Yield."
Zoro froze. The blade bit just enough to threaten his life.
But Zoro wasn't looking at the sword at his throat. He was looking straight into Kenji's eyes. The feral grin on his face didn't fade; it grew wider.
Zoro's right hand tightened on his own katana.
"You care too much about my life, Master," Zoro whispered.
Instead of stepping back, Zoro leaned forward, directly into the sharp edge of the blade at his neck.
