Chiyu left the Loguetown weapon shop with three famous swords now hanging at his waist:
Yama‑arashi
Yubashiri
Sandai Kitetsu
Yama‑arashi and Yubashiri are both among the Fifty Skillful Grade Blades.
Sandai Kitetsu is not, yet as a rare cursed blade it is in no way inferior to the other two.
Chiyu headed toward the execution platform where the Pirate King, Gol D. Roger, had met his end—his mind already fixed on a momentous decision.
He had resolved to abandon his system.
Yes—Chiyu no longer wished to rely on its power.
With the supreme mastery he had attained in the Shinobi World, even though his body was now that of a teenager, he needed no system to return to his peak.
His vision, knowledge, and mental strength were already beyond imagination; such a trifling crutch was unnecessary.
A sharp gleam flashed in his Sharingan.
Of course, abandoning the system did not mean abandoning his ninja abilities.
But he would not walk the old path again: in a new world, he would need a new power structure.
His resolve was to merge the strength he already commanded with this world's forces and forge a road that belonged to him alone.
The thought filled him with excitement—beyond the main goal of purging the One Piece world of evil, he had found another great pleasure.
The execution platform stands in the center of Loguetown's broad main square.
Roger's death here once drew spectators from every corner of the globe.
Many years have passed, yet visitors still flock here; the place bustles with traffic and noise.
Chiyu arrived and looked up at the platform.
It appeared ordinary enough—nothing special, save its historical weight.
Gol D. Roger, like Hashirama Senju in Naruto's world, was a founding figure who shaped today's order—though Hashirama created order, while Roger set off a tempest of chaos.
While Chiyu pondered, commotion suddenly erupted in the square, swelling into a massive brawl.
He raised a brow and quickly understood why: Roger again.
One faction branded Roger an unforgivable villain for plunging the world into turmoil; the other hailed him as a hero who ushered in a new era and inspired countless people to seek the One Piece.
Words failed, fists flew, and the entire square descended into chaos.
Chiyu could not be bothered with such trivial squabbling and turned to leave—but a vast white smoke suddenly rolled over the square, blanketing every combatant in an instant and binding them where they stood.
Smoker's doing, beyond doubt.
The rioters panicked, struggling uselessly.
Smoker landed beside Chiyu. At his command, Marines moved in to seize the ringleaders.
Cigar in mouth, Smoker watched. "I witnessed Roger's execution here with my own eyes. Whatever else, he truly shook the world."
"And yet you despise pirates," Chiyu said.
"I've seen what they really are," Smoker answered. "Whatever Roger intended, the era he unleashed is filled with pirates who rape, burn, and plunder—turning an already rotten world even uglier."
"Sounds as though you've guessed his motives."
Smoker shook his head. "No. I don't know his true aim. A man the Navy and Government could never catch simply turned himself in—claiming illness. There had to be more. He reached Laugh Tale—maybe the only one who truly knew the secret of the One Piece. He must have had a reason."
He exhaled a thick smoke ring. "But that's not my concern. My concern is stopping pirates from running wild. As you've seen, it's near impossible. Arrest one crew and ten more take their place. Roger's spark has become a wildfire."
"Impossible to arrest them all," Chiyu said coldly, "but you can kill them all."
Smoker's eyes narrowed. "You mean—"
"Kill enough of them and people will think twice about becoming pirates. The era's frenzy only proves the Navy's incompetence."
Smoker did not flare up; instead he laughed at himself. "Maybe so. Which is why—why not join the Navy and kill pirates to your heart's content?"
"Because the Navy and the World Government are often no cleaner than the pirates," Chiyu replied.
Smoker fell silent. He knew that was true. "Perhaps. But at least we keep a semblance of order. And as a Marine, you could carve out the rot inside us as well. Could you not?"
Chiyu glanced at him. "Why are you so eager to recruit me?"
Smoker smiled faintly. "Because you might do things I can't—things I dare not, but long to."
"You, the Navy's rule‑breaker, have things you dare not do?" Chiyu asked.
"Too many," Smoker sighed. "Yet from the moment I met you I felt—maybe you can truly cleanse the darkness of this world. And remember: no matter how strong you are, you can't cross the seas alone. You need a ship, a crew—captain, first mate, navigator…"
"I can give you all of that."
Chiyu paused. "You are sincere—and right. Very well, I'll agree. But even in the Navy I will act by my own will."
Smoker's smile widened. "Excellent. If you obeyed orders blindly, I'd never have asked."
Tashigi, having finished rounding up the brawlers, arrived in time to catch this. "Colonel Smoker… are you serious?"
"Enough, Tashigi," Smoker said. "The Navy needs differing wills."
She bit her lip but fell silent.
…
Back at the Loguetown base Smoker placed half his force under Chiyu's command.
"As a branch colonel the best I can do is appoint you Petty Officer—same as Tashigi. I hope you don't mind."
Tashigi and the others were stunned. "Colonel, this man is brutal—yet you give him a rank and half our men? If HQ hears—"
"Let them punish me," Smoker said breezily.
Chiyu nodded. He accepted the arrangement.
Not long after, Smoker announced Chiyu's promotion: Petty Officer in command of roughly two hundred Marines. The base was shaken but could only comply.
Before everyone Smoker asked, "What's your plan, Petty Officer Chiyu?"
"This," Chiyu replied calmly, "is only the start. Step One: purge the entire East Blue."
Smoker's eyes lit up; Tashigi and the others were dumbstruck.
Purge the entire East Blue? Even the "weakest" sea is vast, crawling with pirates, bandits, criminals—impossible to clear out completely! Was he dreaming?
But Smoker was impressed. "Very well. Follow your own will."
To Chiyu—once a police captain, commander, Hokage, ruler of the ninja world—the petty‑officer title meant nothing. A few decisive words, iron methods, and by noon his new unit obeyed him with absolute respect.
Smoker watched in awe.
Finished with the formalities, Chiyu said directly, "I want Rokushiki—the Six Powers."
That was one reason he'd agreed to join: to touch this world's freshest power.
Smoker's expression tightened. "The Six Powers? So you do know a lot. Even I've never trained them—they're not suits everyone. But I can get the manuals."
True to his word, Smoker obtained the secret techniques and handed them over.
Chiyu began studying at once.
The Six Powers—the Navy's supreme martial art. Few mastered even one or two; only prodigies mastered all six:
Soru (Shave)
Geppo (Moonwalk)
Rankyaku (Tempest Kick)
Shigan (Finger Gun)
Tekkai (Iron Body)
Kami‑e (Paper Art)
Soru and Geppo are mobility skills; Tekkai and Kami‑e are hard and soft defenses; Shigan and Rankyaku are the main attacks.
Chiyu thought: this world allows true air‑walking through sheer physical technique—something even Might Guy in the Eighth Gate could barely match. Different rules, different power.
He set to work.
With comprehension and insight far beyond ordinary humans, aided by the Sharingan's analytic power, he pierced every secret in moments, engraving them into body and soul.
Before the astounded eyes of Smoker, Tashigi, and the entire base, he demonstrated:
Soru—vanishing flash to tens of meters away
Geppo—walking through the sky
Tekkai—muscles hardened like steel
Kami‑e—body loose as paper, slipping through gunfire
Shigan—a finger thrust that pierced stone
Rankyaku—a kick that unleashed a vacuum blade, slicing targets in two
Smoker nearly dropped his cigar; Tashigi's mouth fell open.
"Wh‑what kind of monster masters all Six Powers after just reading the manual?!"
Even CP9 prodigy Rob Lucci needed countless hours—yet Chiyu grasped them in an instant. A true genius.
Chiyu nodded slightly. "So this world's powers are impressive after all."
But mastering the basics was only the beginning. His goal: weave the two worlds' powers into one. It would take time.
Smoker, Tashigi, every Marine—held their breath, overawed by his demonic talent and god‑like presence.
…
Days later Chiyu felt at home in this world and put his "Cleanse East Blue" plan into motion.
Smoker himself could not leave Loguetown; it was the gate to the Grand Line.
But Chiyu answered to no one.
He took a Navy ship of his own, named it the Uchiha, and, with about two hundred Marines, prepared to set sail.
His course ran opposite that of Monkey D. Luffy's: from Loguetown deeper into the East Blue, to root out every pirate and evil.
The year was Sea Calendar 1515—about five years before the original One Piece story begins.
Thus began the great legend of Uchiha Chiyu.
