Konoha Year 42. Four years remained before the full outbreak of the Third Shinobi World War.
It was April, the season when cherry blossoms bloomed in full.
Within a well-kept courtyard, a strikingly handsome boy—so good-looking it bordered on absurd, much like the readers themselves—stood upright beneath a cherry blossom tree, his posture straight as a drawn blade.
"Clang!"
The katana slid free from its sheath. A cold, silver-white gleam swept across the boy's face, lighting the unwavering resolve in his eyes.
"Swish, swish, swish!"
In his hands, the blade seemed alive, each motion crisp and precise, the air itself ringing with a clear, resonant hum.
Three drifting cherry blossom petals froze in midair for the briefest instant. Then they quivered—before silently collapsing into fine pink dust.
[Host has accumulated one hundred million katana swings. Reward granted: Roronoa Zoro's exclusive blade, Wado Ichimonji. Stored in personal space. Host may retrieve it at any time. Current Zoro Synchronization: 8%.]
Uchiha Zoro lowered his sword and casually wiped the sweat from his brow. His gaze lingered on the scattered dust where the petals had been, his expression turning faintly thoughtful.
"Without realizing it… I'm already close to seven," he murmured. "Time to step into the open. The clan tournament… huh."
A faint, indifferent smile touched his lips. He lifted the blade slightly, and his reflection shimmered along its polished surface—sharp features, steady eyes, and a composure far beyond his years.
He was not originally from this world. In his previous life, he had simply fallen asleep—only to awaken here, in a foreign land, with a single advantage: the template of the great swordsman Roronoa Zoro.
Even so, only he truly understood how grueling these past six years had been.
One hundred million swings is what the system required of him the moment it appeared.
A number he would never have imagined attempting—yet he had completed it, one strike at a time.
The system did not accept idle motions. Every swing demanded full commitment—body, mind, and spirit perfectly aligned. A single lapse in focus, and it would not count.
At times, Uchiha Zoro felt the system had not rewarded him at all, but merely recorded the result of six years of relentless discipline. In the end, it was nothing more than a cold, impartial counter.
"Young Master Zoro, training again?"
The sharp sound of the blade drew the attention of a jōnin stationed atop the courtyard wall. Seeing the boy standing silently beneath the falling blossoms, a trace of admiration flickered in his eyes.
"Sigh… Young Master Zoro really is obsessed with the sword."
Another guard, a chūnin, clicked his tongue softly, his tone carrying a hint of disappointment.
For six straight years, Zoro had done little but swing his blade.
He swung while eating, swung while walking—even in his sleep, his body would unconsciously mimic the motion.
Some even said he practiced swordsmanship in his dreams.
Before long, the nickname "sword maniac" had quietly spread throughout the clan.
To them, he was simply a boy consumed by the blade. Whether he was a genius or a fool—no one could say.
And no one dared to find out.
Because Uchiha Zoro was the only grandson of Uchiha Muneyoshi, the leading figure of the clan's dovish faction.
Zoro's father—Muneyoshi's son—had died on the battlefield the very day Zoro was born.
Since then, the old man's protectiveness had reached near-obsessive levels.
In his eyes, a child who had lost both parents deserved, at the very least, a peaceful childhood. And under considerable pressure from within the clan, he had managed to secure exactly that.
However—
Only the weak would cling to such peace.
Uchiha Zoro understood that better than anyone. The faint hesitation in his gaze faded as he sheathed his blade and turned toward the courtyard gate.
He was grateful to Uchiha Muneyoshi for those six years. Though he retained memories of his previous life, he had long since accepted the old man as his grandfather.
Muneyoshi, for his part, knew that Zoro's talent in ninjutsu was nothing exceptional. He had even considered inviting the renowned White Fang, Sakumo Hatake, to personally instruct him.
Unfortunately, Zoro was still too young. As a student who had yet to graduate from the Ninja Academy, he had no right to choose a mentor.
The memory faded.
Zoro now stood in the center of the training grounds, gripping a wooden sword. A thin line of blood ran down from his forehead, but he didn't bother to wipe it away. His dark clothing fluttered lightly, though there was no wind.
Around him, every member of the Uchiha youth lay sprawled across the arena floor.
Defeated.
His gaze remained calm—steady, unwavering, without the slightest ripple.
There was no surprise in his eyes.
Of course he had won.
He was, without question—
The strongest among the Uchiha youth.
Among those lying on the ground, the oldest was already ten years old, with strength comparable to a seasoned genin.
"Th-the final champion of this clan tournament… is Uchiha Zoro."
The referee snapped out of his daze and announced the result, his voice tinged with disbelief. His eyes remained fixed on the boy at the center of the arena—like a blade freshly drawn, dazzling and impossible to ignore.
Six years honing a blade—draw it once, and it stuns the world.
"Young Master Zoro… he actually won?"
"Th-this… he's a swordsmanship prodigy?!"
Shock rippled through the crowd. Eyes widened, mouths fell open. The same "sword maniac" they had dismissed—perhaps even mocked—had revealed himself to be a true genius.
Even the jōnin guard stood frozen, staring at Zoro. Scenes of the boy's countless swings surfaced in his mind, each one now vivid and undeniable.
Perhaps…
Genius was never something that appeared overnight.
"Second Elder, your grandson doesn't seem weak at all."
Uchiha Fugaku, the clan head, spoke with a faint smile as he turned to the man beside him—Uchiha Muneyoshi. As he did, his thoughts drifted to his own unborn son.
He wondered if, one day, that child would stand at the center of such a stage as well.
"Second Elder, you've been shielding him all this time… yet he's clearly a sword prodigy. Why reveal it only now?"
Nearby, the First Elder of the hawkish faction, Uchiha Setsuna, spoke with restrained dissatisfaction.
At just six and a half years old, he had already defeated opponents with genin-level strength. If properly nurtured, wouldn't he become another prodigy on par with Kakashi Hatake?
At present, Kakashi Hatake had already advanced to chūnin at the age of eight. Though still burdened by the grief of his father's death, it did nothing to diminish his reputation as a genius.
As if sensing something, Zoro's gaze shifted toward the elevated platform where the clan leadership sat.
The coming Third Shinobi World War.
The night of the Nine-Tails' rampage.
And the future massacre that would wipe out the once-proud Uchiha clan.
Memories surfaced in his mind, one after another. His grip on the wooden sword tightened imperceptibly.
All of it—
He would stop it.
