One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

The waves gently lapped against the hull of the White Dove, and the outline of the island was clearly visible.

On the deck, Barrett was still in a state of excitement, with wisps of air swirling around him.

Roy smiled, watching the island getting closer and closer. He released his Observation Haki and spotted two figures in the very center of the island. Their auras were sharp as swords, although one of them was still 'weak'.

"Two people? Interesting!"

In the central castle of Kranagai Island, an old man and a young man were practicing swordsmanship. Just as Roy's Observation Haki was spreading, one of them stopped the training.

"What's wrong, teacher?"

"We have 'guests' arriving on the island, so let's return to the castle first. That concludes today's training."

The old man put away his long sword and walked into the castle.

The White Dove slowly sailed into a secluded bay.

After mooring the boat, the group stepped onto the island's land and followed Roy's footsteps, slowly walking towards the center of the island.

The island is covered with lush vegetation, and the ruins peeking out from between the plants suggest that many people once lived here.

The forest was shrouded in thick fog, and the eerie environment made the youngest member, Savi, instinctively move closer to Barrett.

Tesoro also felt uneasy, as if countless eyes were watching him from the surrounding dense forest.

"Boss, this island is so eerie. Do people really live here? I have a feeling that someone is spying on us."

"Yeah, yeah, boss, I feel the same way too," Savi, walking beside Barrett, chimed in.

Roy patted Pea, who was following him, and explained to the others.

"Kraigana Island, this was originally the location of the Kingdom of Sikel."

"But it was later destroyed in a war. Legend has it that the apes on the island learned to use weapons by observing human conflicts."

"These are the monkeys watching us from the woods."

Following Roy's introduction, the group walked through the jungle and came to a rather well-maintained castle.

At the castle gate, two figures were waiting for Roy and the others.

The leader was a tall, elderly man dressed in a kimono and carrying a black sword.

A pair of sharp eyes stared at Roy and his group, emanating an invisible sense of oppression.

The black-haired boy beside him, about eleven or twelve years old, held a long sword taller than himself, and his eagle-like eyes were warily scrutinizing the newcomer.

The atmosphere in front of the castle seemed to freeze.

The old man's gaze slowly swept over Roy and his group, finally settling on Roy at the front.

"Uninvited guests, please state your purpose."

"Why are you here? I just happened to be passing by and thought I'd come up and take a look!"

Roy stepped forward with a smile on his face, and his gaze immediately fell on the boy and the black knife.

"Oh! The Supreme Grade Sword!"

This young man is none other than the future world's greatest swordsman, Hawkeye Mihawk. At this moment, he sees Roy opposite him staring intently at the sword in his hand.

Hawkeye unconsciously clenched his fists even tighter.

Seeing this, Roy's smile widened even more.

Hawkeye is still just a kid now, far from having the cocky, carefree attitude he'll have later when he's sailing around in a fancy little boat!

Thinking back to the One Piece fans of the past, you know, Hawkeye was rowing alone at night with his black sword, and when the Krieg Pirates saw him, they chased after him all the way.

Roy couldn't help but laugh out loud.

"Hahaha~"

At this moment, Hawkeye Mihawk was completely bewildered by Roy. First, he stared at the knife in his hand, then looked at himself strangely and grinned foolishly. "This bastard is definitely mocking me."

"Roy the Pirate, are you looking down on me?!"

"Oh! How do you know my name?"

"Hmph~ By now, your deeds should be known everywhere!"

"Is the navy that fast? Can I see the newspaper?"

"Oh, okay." With that, Hawkeye turned and walked into the castle.

Seeing his disciple being easily fooled by a few words, the old man beside him could only sigh and smile wryly, his imposing aura dissipating.

"Could it be that he's been practicing swordsmanship with me since he was a child, and it's made him stupid?"

Thinking about it, he reached out and stopped Hawkeye, looking at Roy who was trying his best to suppress his laughter.

At this moment, Hawkeye realized what was happening and his face turned bright red.

"You bastard! You were just playing me for a fool."

"No, no, I was just thinking about something happy."

Upon hearing Roy's perfunctory reply, Hawkeye immediately raised the black sword "Night" in his hand.

"You bastard, what happy thing have you thought of? If you can't tell me, I'll chop you up!"

"Uh~" Roy's expression froze. He couldn't tell him what the One Piece fans were guessing.

Seeing Roy standing there in a daze, Mihawk knew that this guy must have been playing a trick on him, and he raised the black knife in his hand to make a move.

"Wait a moment!"

Roy quickly called for a stop, and Hawkeye actually stopped in his tracks. Roy turned around and took out his sword from the storage bag on Pea's body before turning back to signal that they could begin.

Realizing he had been tricked once again, Hawkeye forgot his anger at being fooled. Now, his expression was icy, and he unleashed a slash.

Seeing this, Roy also put away his teasing smile, covered himself with Armament Haki 'Frost', and shattered the flying sword energy with his longsword.

"Not bad swordsmanship."

Roy also sincerely admired him, saying that being able to use a flying slash at such a young age was truly worthy of being the future world's greatest swordsman.

"Stop talking nonsense!"

Seeing his attack so easily shattered, Hawkeye lunged forward, his black sword Night drawing a graceful arc in the air, heading straight for Roy's face.

Roy raised his sword to meet the attack. Although his "Frost" sword was not as strong as Hawkeye's, with the help of Armament Haki, he was not at a disadvantage.

"It seems Hawkeye hasn't mastered Haki yet." Roy thought to himself as he parried.

"Clang clang clang—"

Hawkeye's attacks were like a storm, but Roy relied on his advanced Observation Haki to accurately block every strike.

Barrett's eyes lit up, and his fists clenched unconsciously. "He's definitely a worthy opponent."

Tezzolo and Savi watched the old man nervously, fearing he might attack together.

The old man simply watched the two fighting in the arena quietly, without making any move.

Hawkeye grew increasingly angry as the fight progressed. He noticed that Roy was only blocking and hadn't launched a single attack.

"What do you mean! Are you looking down on me! Why did you only block?!"

"As you wish!"

"One-Sword Style: Mental Storm!"

Roy's speed suddenly increased, his mental energy imbued with the blade, his arm raised high, and he slashed down diagonally.

Faced with Roy's sudden acceleration, Hawkeye raised his black blade. Just as the blades were about to collide, an invisible surge of mental energy impacted Hawkeye's brain.

Dizziness, confusion, and a whole host of other emotions overwhelmed Hawkeye. His mind was a jumbled mess, the world spinning around him, and he no longer had the strength to pick up the black knife.

Wow~~~

Black Knife Night fell to his feet, and Roy saw Hawkeye get hit by his own knife, causing a small rainbow to come out of his mouth.

He quickly sheathed "Frost and Snow".
