One Piece: My code name is Green Bull

The young swordsman's fearless gaze irritated BIG MOM.

With a cold snort, she demanded, "Brat, my pirate crew has no quarrel with you. Why are you chasing us?"

The young man answered indifferently, "Just practicing my swordsmanship."

"What?"

BIG MOM couldn't believe her ears.

This kid had been hunting them down—just to practice his sword skills?

"Is he insane?"

"You dare use MY pirate crew for sword practice? You've got some nerve, brat."

The young swordsman remained unfazed. "Enough talk. If you want to kill me, then do it. If not, I'll strike first."

BIG MOM's rage boiled over.

She was being mocked by a mere boy!

She glanced at the approaching ship, her mind racing.

For someone to boldly sail toward a pirate ship, they were either a fool—or dangerous.

Had it not been for this fearsome young swordsman, she wouldn't be too concerned.

But after witnessing his frightening skill, she doubted her crew's ability to handle another strong foe.

Just as she hesitated, the young swordsman suddenly lifted his head, looking toward the approaching vessel.

Instinctively, BIG MOM followed his gaze.

A shadow shot into the air from the ship—

Gliding through the sky as if walking on air, moving rapidly toward them.

"Marine Six Styles—Moonwalk?"

BIG MOM gasped.

She had fought Marines before and recognized Rokushiki immediately.

Now, she was even more alarmed.

That ship clearly wasn't a Marine warship—so why did a Marine capable of using Rokushiki suddenly appear?

Her luck was truly rotten.

First, she had a terrifying young swordsman to deal with.

Now, a Marine had entered the scene.

As the figure closed in, BIG MOM roared, "Shoot him down!"

The pirates scrambled to react, but only a few managed to raise their rifles in time.

Gunshots rang out, but—

Jon effortlessly dodged, leaping through the air with fluid Moonwalk movements.

Not a single bullet hit him.

"Bang!"

Within seconds, Jon landed gracefully on the pirate ship—

Right in the middle of the enemy crew.

"Guns? What a warm welcome."

Jon smirked as he casually scanned the area.

He barely glanced at the pirates, but when his eyes landed on the young swordsman, he froze for a moment.

"Marine! You're a Marine!"

BIG MOM shouted furiously, and the pirates immediately went on high alert.

Jon's smirk faded, his eyes turning cold.

"That's right. And unfortunately for you, that means your luck just ran out."

BIG MOM snarled, "I've killed plenty of Marines before. A brat like you dares step onto MY ship? You must have a death wish!"

Jon's voice grew even colder.

"Oh? You've killed Marines?"

"In that case, I definitely can't let you live."

Jon wasn't as extreme as Akainu, but he despised pirates—especially those who had murdered Marines.

He had neither the time nor the patience for arrests.

Elimination was the only option.

But before he could act—

The young swordsman spoke.

"I was here first. They're mine."

Jon blinked, stunned.

Turning to face the swordsman, he took a closer look—

And his brows furrowed.

"Why does he look so familiar...?"

Jon's mind raced.

A young man—around 18 or 19—dressed like a noble—already at Swordmaster level?

Suddenly, a name surfaced in his mind.

"No way... Is he—Hawkeye?"

Among the legendary swordsmen Jon could recall, only one fit the description—

The future World's Greatest Swordsman—Dracule Mihawk.

Jon scrutinized the young man again.

And the more he looked—

The more the resemblance became undeniable.

To confirm his suspicion, Jon decided to test him.

"You want to use them for sword practice? Fine. I'll give you that chance."

Surprisingly, the young swordsman nodded and said—

"Thank you."

Jon chuckled.

"This kid is interesting."

Meanwhile, the pirates were livid.

Especially BIG MOM.

Her eyes burned with fury as she glared at both Jon and the swordsman.

"Kill them! Take out the brat first!"

Despite her rage, BIG MOM wasn't reckless.

She didn't attack Jon immediately—instead, she ordered her crew to kill the swordsman first.

But before the pirates could act—

The young swordsman moved first.

A flash of steel—

And several pirates dropped dead.

Jon, who had planned to kill pirates himself, found himself watching instead—

Becoming a spectator to the swordsman's one-man massacre.

BIG MOM didn't attack—

She was too busy watching Jon, wary of his potential strength.

One young swordmaster was already overwhelming her crew.

And now, an unpredictable Marine had arrived.

Even though Jon hadn't fought yet—

She couldn't afford to let her guard down.

But soon—

She couldn't hold back anymore.

The swordsman was cutting through her men too quickly.

Within moments, half of her crew was slaughtered.

BIG MOM gritted her teeth, deciding she could no longer wait.

She raised her massive spiked club—

And charged at the swordsman.

Jon carefully observed the battle.

The swordsman's techniques were bold and aggressive, his blade cutting with terrifying precision.

The only thing missing was the cross-shaped black sword Jon remembered—

But everything else—

Was exactly like Mihawk.

The fight didn't last long.

Even with BIG MOM herself joining, she was no match.

Soon—

Her entire crew was wiped out.

The few survivors barely clung to life.

And as for BIG MOM—

She had been cut dozens of times, her body covered in deep wounds.

A horrifying sight.

But the swordsman's face remained emotionless—

As if he felt nothing.

"Brutal."

Jon couldn't help but be impressed.

Even though the swordsman hadn't used his full strength—

His skill was undeniable.

A young man with this level of swordsmanship was almost unheard of.

After finishing his slaughter, the swordsman didn't kill the remaining pirates.

Instead, he simply stood there—

And turned to face Jon.

Jon's eyes flicked toward the wounded pirates, his expression cold.

"You should always finish the job—especially with pirates."

He snapped his fingers—

And suddenly—

Green light flickered around him.

Dozens of sharp, glowing leaves materialized—

Floating in the air like deadly blades.

"Willow Leaf Daggers!"

The razor-sharp leaves shot forward—

Slashing through the remaining pirates—

Erasing them completely.
