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

Roy drew his sword, Autumn Water, and aimed the tip at the joint of the wooden planks.

With a slight flick of his wrist, the entire wooden board was lifted up.

"Click".

With a soft sound, a hidden compartment the size of a shoebox appeared behind the wall.

"Wow, there really is something there!"

Tezzolo's eyes lit up.

Carefully remove the sphere wrapped in black velvet.

Roy took the ball, weighed it in his hand, and found it to be quite heavy.

Unfasten the buttons and slowly peel back the velvet fabric.

A fruit, entirely deep blue and covered with spiral patterns, lay quietly in the velvet cloth.

The fruit's shape somewhat resembles an enlarged plum.

The outer skin, however, is a dark, almost rock-like grayish-brown.

At the top of the fruit, there is a blurry bulge resembling human facial features, which looks both crying and laughing, carrying a strange sense of comicality and vicissitude.

"Devil Fruits..." Tesoro murmured, a hint of curiosity flickering in his eyes.

"Boss, judging from the patterns and colors, it doesn't seem to be a typical Zoan or Paramecia type. Could it be...?"

"It should be a mythical beast."

Roy weighed the fruit in his hand, already having made up his mind, observing its physical characteristics.

It should be the Human-Human Fruit Mythical Zoan type Dainyūdō form that the fox ate in the original work (giant size, super strength, and an image similar to "Dainyūdō," which is the image of a giant monster in Japanese folklore).

"Huh?! Really?" Tesoro exclaimed in surprise.

"Is it a mythical beast species like Barrett and Pea?"

"It should be."

Roy wrapped the fruit again in the velvet cloth and put it in his pocket.

"Alright, we'll know once we go back and compare it with the fruit encyclopedia."

"Let's leave here first."

Tesoro nodded, and the two left the cabin without lingering, soaring into the sky.

In the night sky, Roy glanced back at the cemetery that was gradually disappearing into the wind and snow.

This harvest far exceeded expectations. Not only did they obtain the Black Blade Shusui, but they also unexpectedly found this Devil Fruit that is suspected to be a Mythical Zoan type.

"Where to next, boss?"

Roy pondered for a moment, then shook his head.

"Let's go back to Onigashima and wait for Kaido to return."

"Once things are settled with Kaido, you can come to the Wano Country mainland whenever you want."

"All right!"

Tesoro said no more, and the two of them cut through the sky, tearing through the night wind and clouds, and sped toward Onigashima!

It was still dark.

Roy and Tezzolo silently climbed into the room through the window.

Inside the room, Barrett sat cross-legged in the center, eyes closed, resting.

Hearing the noise, he opened his eyes, looked at the two of them, then closed them again to continue his cultivation.

Roy gestured for Tezzolo to be quiet, and the two returned to their respective beds.

Roy took out the Devil Fruit from his pocket and, by the faint moonlight streaming in from the window, examined the fruit carefully once more.

He took out the Devil Fruit encyclopedia from his storage bag.

Quickly flip to the section on mythical beast species and start comparing.

"Human-Human Fruit, Mythical Zoan, Great Enlightenment Form..."

Roy's finger stopped on a page of the encyclopedia.

"Yes, that's it."

Roy closed the encyclopedia and placed the fruit together with the other fruits.

Roy lay in bed, deep in thought.

"Currently, I have four Devil Fruits in my collection (Paramecia-type Fusion Fruit, Paramecia-type Weapon Fruit, Paramecia-type Ghost Fruit)."

"In addition to what I just acquired, the Human-Human Fruit, Mythical Zoan type, Great Enlightenment form."

"Roy believes all four Devil Fruits have immense potential, but most of his crew members are currently Devil Fruit users."

"The remaining two, Hawkeye and Charon, will not eat Devil Fruits."

"It seems we need to find a few more promising crew members."

The next morning, everyone gradually woke up.

Roy briefly told everyone about what he had gained the previous night and then showed them Qiu Shui.

"A black knife?!"

Mihawk, now dressed in Wano Country attire, took the Shusui and examined it closely, his fingers lightly tracing the blade as he felt the sword intent and the traces of its domineering tempering.

"How is it?"

"Excellent."

Hawkeye handed the knife back to Roy.

"This is already a fully forged black blade, however..."

"Perhaps it's been too long, the 'spirit' within the knife seems to have become somewhat dormant."

"Yes, I will gently nurture it and help it regain its luster."

Roy took the Autumn Water sword, sheathed it, nodded, and then glanced at Hawkeye, who was dressed as a samurai.

Are you going now? Do you need me to give you a ride?

"No need. Onigashima isn't far from the Wano Country mainland; I can get there using Moonwalk."

You should stay here and guard the area; Kaido might be back anytime soon.

"All right."

As everyone was talking, footsteps came from outside the door.

"Knock knock—".

Tesoro opened the door, and King appeared outside, followed by a group of pirates, each carrying a tray filled with various foods.

"Please use it."

Jin waved his hand, instructing his men to fill the table with food. His gaze swept over the Autumn Water at Roy's waist, and his pupils contracted almost imperceptibly.

Roy noticed these details but didn't point them out.

"When will Kaido return?" Barrett asked directly.

"Three days."

"The Governor is on his way back."

"Three days... okay." Roy nodded. "Then we'll be staying here for the next three days."

Upon hearing Roy's answer, Jhin nodded, but his gaze remained fixed on Hawkeye, who was dressed as a samurai.

"this……"

Don't worry.

Roy pointed to Black Knife Night behind Hawkeye.

"Mihawk is a pure swordsman. Having come to this land of warriors, he naturally wants to spar with the warriors here."

"It won't cause any trouble."

Hearing Roy's explanation, Jhin could only nod helplessly.

It's because Kaido isn't here; there's no one on Onigashima who can keep the Roy Pirates in check.

Jin nodded to everyone and left the room.

Meanwhile, in a room on Ghost Island, Jack, the "Shipping King" who had been knocked unconscious by Barrett, had woken up.

Beside him, a tall, blond girl, only 15 or 6 years old, with two long pink horns on her head, was being dressed by the Black Maria.

"Jack, who hit you? You're so badly injured!"

"Ouch—it hurts!"

Jack slapped Maria's large hand away, sat up with a grimace, and the image of Barrett's hateful smile flashed through his mind.

"That bastard... I'll never let him get away with this!"

In a corner of the room, several children of similar age were gathered together.

With long purple hair and a stern face, Page Van (12 years old) crossed his arms.

"They knocked you out with one punch, Jack. Are you sure you want revenge?"

"Yes, yes, Jack, you were knocked out in no time. I think you should stop calling yourself Kaido's top lieutenant and just give him to me."

"Isn't that right, Xiao Pei!"
