<><><><><><>

The time quickly flew by, and the day of Byakuya's duel with Mihawk arrived. Their agreed meeting place was on Mihawk's secluded island. 

Early in the morning, Byakuya set sail aboard the Arctic Daylight. 

Standing at the ship's bow, his sword hung at his waist while his cape billowed sharply in the sea breeze. 

His demeanour exuded an indescribable sharpness akin to a long-hidden sword about to be unsheathed.

Not far behind him, Fujitora and Aokiji stood deep in conversation.

"Fujitora, why has Byakuya been so cold and distant ever since he got injured that day? He won't even speak to us," 

Aokiji asked thoughtfully, his gaze fixed on Byakuya's back. "You're also a master swordsman—any idea what's going on with him?"

Fujitora, gently running his hand along his cane sword, replied calmly, "I understand how he feels." 

"I've faced Mihawk before. His strength is no less than mine or Byakuya's." 

"The pressure of this duel must be immense, forcing Byakuya to focus entirely on the upcoming fight."

Aokiji nodded, enlightenment dawning. "Makes sense. As expected of fellow sword masters, your insight runs deep."

"Understand me?" Byakuya, having overheard their conversation, smirked coldly. Understand what, exactly? He thought darkly. 

Every word you say is nonsense. I'm avoiding you both because I might lose control and draw my sword on you.

He couldn't help but recall the disastrous day when Aokiji's words had inadvertently caused the Red-Haired Pirates, Whitebeard Pirates, and even Big Mom's crew to escape. 

They had taken with them countless opportunities to plunder world essence and bountiful treasures. 

Worse, Fujitora had restrained Byakuya, preventing him from acting. Every time he thought about it, rage boiled within him.

"Look!" Aokiji exclaimed suddenly. "Byakuya's body is trembling, and his aura seems unstable!"

Fujitora nodded gravely. "It must be lingering injuries from his clash with Shanks."

"Then wouldn't this duel with Mihawk be incredibly dangerous for him?"

"Indeed. If it comes to it, we must intervene to save him," Fujitora said solemnly.

Aokiji, brimming with confidence, reassured him. "Don't worry. With me here, I'll make sure nothing happens to him."

Unbeknownst to them, their words only fueled the growing sharpness of Byakuya's aura. 

Out of sight, he clenched Wind Howl tightly, repeatedly telling himself to stay calm. Don't lose it. 

If I cut these two down, all my efforts will go to waste. 

After this internal struggle, Byakuya and his companions finally arrived at Mihawk's island. 

The place was already swarming with spectators, who had paid a hefty price for witnessing this battle.

When Byakuya disembarked, the crowd parted to create a path for him, murmuring in awe at his commanding presence.

Byakuya leapt from the ship, landing gracefully on the soft sands. 

The island featured two parallel mountain peaks of identical height, forming a natural stage for the duel. 

Mihawk stood stoically atop the left peak, waiting. Byakuya climbed the right peak, but as he stood there, he noticed something peculiar about the island.

This place feels... off. These two peaks... If you told me they were shaped like a certain part of the human body, I'd believe you. 

The bizarre resemblance reminded Byakuya of Gill Island's equally uncanny landscape. 

Curious, he asked, "Mihawk, do you know this island's name?"

Mihawk, puzzled by the question, replied, "The island's name? I just randomly chose this place from the sea. It's uncharted and doesn't appear on any Log Pose."

Hearing this, Byakuya's interest was piqued. "If it's nameless, why don't we give it one?"

Mihawk frowned slightly. "We're here to determine the world's greatest swordsman, not to play around."

Byakuya ignored the remark. "Exactly." 

"Since this duel will crown the world's strongest swordsman, it's only fitting to name the battleground where it happens."

Mihawk paused, considering Byakuya's logic. It would make the duel sound more grandiose in retellings. 

Eventually, he nodded. "Fair enough. Do you have a suggestion?"

Byakuya grinned. "Let's call it Forbidden Peak Island."

The name fits perfectly—two duelists competing for the ultimate title atop twin peaks. 

It even evoked imagery reminiscent of the legendary duel in classic wuxia novels. 

Mihawk, who was notoriously bad at naming things, agreed without hesitation.

Satisfied, Byakuya unsheathed Wind Howl and declared, "This is Kazemune, one of the fifty Skillful Grade blades, forged from Jack's ivory and soon to be imbued with Kaido's dragon horn."

Mihawk raised an eyebrow, his usually composed demeanour faltering slightly. 

Jack's ivory? Kaido's horn? For the first time, even Mihawk found himself curious about Byakuya's peculiar choice of materials.

With their introductions complete and the island named, the duel between two of the greatest swordsmen in the world was about to begin.

Kaido's dragon horns aside, Jack's ivory might be more feasible. Maybe I should give it a shot someday. 

But now isn't the time for such thoughts. Mihawk, ever composed, drew his blade, the legendary Black Blade: Yoru, and declared coldly, 

"Supreme Grade Blade, one of the Twelve, Black Blade: Yoru!" 

With formalities completed, the battle was ready to commence.

The spectators around the mountains couldn't hold back their excitement as they speculated, "Who do you think will win and claim the title of the World's Strongest Swordsman—Byakuya or Mihawk?"

"Isn't it obvious? Mihawk, of course!" 

The voice came from Vista, the Flower Sword and Fifth Division Commander of the Whitebeard Pirates. 

The crowd turned toward him in surprise. 

Having left the Whitebeard Pirates with Ace and Marco just days ago, Vista couldn't resist witnessing this duel between the finest swordsmen on the seas. 

Following the Whitebeard Pirates' allied crews, he returned to the scene, eager for the event.

Vista's reputation as a formidable swordsman in the New World made his opinion highly regarded. 

When asked for his reasoning, he explained confidently, "Byakuya was injured recently in his clash against Shanks' Conqueror's Haki." 

"There's no way he's fully recovered in such a short time." 

"Meanwhile, Mihawk has earned his title through countless battles, recognized by all swordsmen as the strongest." 

"Byakuya's feats, on the other hand, remain shrouded in vagueness, known only through sparse accounts and rumors." 

"Considering everything, Mihawk is the more likely victor."

Vista's analysis resonated with the crowd, who believed they could predict the battle's outcome. 

Nearby, Ain and Tashigi overheard the discussion and turned to Issho and Kuzan with concern. 

"Do you think Byakuya will lose?" Ain asked, her voice tinged with worry.

Issho hesitated, recalling Byakuya's trembling during their journey here. 

"It's hard to say. If he truly loses, Admiral Kuzan and I will do everything in our power to protect his life."

Kuzan, less serious than Issho, tried to reassure them. 

"Relax. Byakuya's got at least a third of my strength. He's not going down that easily against Mihawk."

Amid the conversations, Byakuya charged directly at Mihawk, wielding Kazemune without a probing strike. The spectators gasped in shock. 

Vista, watching closely, nodded knowingly. 

"He's panicking. Look at that—he's not even testing the waters with a slash. If this keeps up, his defeat will come even quicker."

Mihawk, having sparred with Tashigi and Ain earlier, had gained some insight into Byakuya's swordsmanship—its hallmarks being unparalleled speed and devastating cutting force. 

Over the past two weeks, Mihawk had devised counters for these very attributes. 

So when Kazemune came crashing down at an extraordinary speed, the Black Blade: Yoru, ready and waiting, intercepted it from an uncanny angle.

Clang!

The sharp clash of steel echoed through the air, scattering clouds across the skies within a radius of ten thousand miles. 

Mihawk successfully blocked the strike, but his heart sank rather than rejoicing. He became even more cautious.

Though Mihawk had prepared for Byakuya's speed and cutting prowess, he had completely underestimated the raw power behind the blow. 

His right hand trembled from the impact, and his entire arm felt numb. 

"Is this even a sword? Feels more like a hammer's brute force," he thought grimly. 

This sensation reminded him of facing an opponent far superior in strength—a disparity akin to that between a male and female swordsman of equal skill.

Unfortunately for Mihawk, he was akin to the weaker swordsman in this matchup.

Byakuya, too, was surprised. That strike had carried slightly more force than usual, yet Mihawk had managed to block it. 

"Impressive. No wonder he's the World's Strongest Swordsman," Byakuya mused.

Before Mihawk's arm could fully recover, Byakuya launched a new assault.

"Armament - Normal Series: Atomic Slash"

In an instant, Mihawk seemed to blur in Byakuya's eyes, replaced by images of Issho and Kuzan. 

The memories of their past actions fueled Byakuya's relentless aggression. 

Without hesitation, he poured his fury into Kazemune, enveloping the blade in an abyssal coating of Armament Haki that was so dense it seemed to devour all the light around it.

"Your blade… it's a Black Blade too!" Mihawk exclaimed in shock.

To the spectators, Kazemune appeared to vanish entirely as Byakuya's slashing speed surpassed even Mohawk's expectations. 

The blade streaked through the air like a beam of light, impossible to track with the naked eye. 

Though the strike hadn't landed yet, its sheer cutting force shredded Mihawk's clothing in multiple places. 

Forced to rely on his Observation of Haki, Mihawk narrowly managed to perceive and react to Byakuya's assault.

Clang! Clang! Clang!

A rapid succession of collisions rang out as Mihawk deflected strike after strike. 

But the mountain beneath his feet began to crumble under the relentless pressure. 

Rocks tumbled down as cracks spread across its surface, and its height steadily diminished.

Mihawk wanted to counterattack, but to his frustration, Byakuya's stamina seemed limitless. 

Each strike carried the same unwavering power and precision as the last, as if meticulously calculated. 

Faced with such relentless ferocity, Mihawk could do little but defend.

"Byakuya… he's overpowering Mihawk," someone in the crowd muttered in disbelief.

The spectators were stunned, their eyes fixed on the unfolding battle. This wasn't what they had expected at all. 

How could the outcome deviate so drastically from what they had envisioned?
