Chapter 1: So Casual?

At two-thirty in the morning.

"Huh?"

"People in the Pirate World, I'm Roger's friend."

"Nice name, let's take a look."

"Seriously? Watching an anime episode could lead to death and a trip to another world? Who would believe that!"

"Well, I certainly don't."

"Huh? Wasn't I just reading a novel? Did I fall asleep??"

As his consciousness gradually returned, Kaito Sakamoto opened his eyes. But as soon as he did, the glaring sunlight nearly blinded him.

"Damn it, who set off a flashbang!!!"

"My eyes! My eyes!!"

"Please remain quiet!"

Kaito was covering his eyes and trying to "heal" by shouting, when suddenly a strange voice popped up.

It felt as if the voice was inside his head; in fact, it was.

"Who!?"

Kaito immediately asked, still not opening his eyes. If that "flashbang" went off again, he might lose his sight for good.

"I am System 000, the system that manages all systems."

A cold mechanical voice introduced itself.

"System?"

"Did I really cross over?"

"Where am I? What world is this??"

Kaito didn't expect that one moment he would be complaining about crossing over, and the next he would actually do it.

What is this?? Complaining has its risks; speak cautiously!?

"This is the world of 'One Piece,' and the main character is Monkey D. Luffy."

"You didn't believe in crossing over, did you?"

"Now do you believe it?"

It was still the mechanical voice, but it carried a tone of, "How dare you doubt me?"

Kaito was stunned. "So, you really just crossed me over because I complained? It's that casual???"

The system didn't respond.

"Forget that for now. Am I stuck here?"

Kaito asked.

"If nothing unexpected happens, yes."

The system answered decisively.

While the system was straightforward, Kaito felt speechless, mentally thanking its ancestors, even if they didn't exist.

Since this was the case, Kaito could only comfort himself by accepting his fate. After all, he was also an orphan in his world, with nothing to hold on to. It was better to relax and accept the destiny of his crossing over.

At first, he couldn't accept it, but then he managed to do so.

"Well, since you brought me here, you must be my cheat code?"

"What did you say you were? The management system?"

"Though you look ugly, you think highly of yourself."

"I am the system that manages all systems. If I became your system, serving only you, wouldn't that be chaos?"

The system responded with a tone of mocking.

Kaito really wanted the ability to slap that "person" through the screen.

"So, what's the deal? You bring me here and plan to just leave?"

Kaito asked, feeling that if the system was just going to leave after its job was done, it had no ethics.

"...."

Silence, a three-second silence.

It was as if Kaito guessed the system's thoughts.

"You wouldn't…"

"Of course not!!"

"I will randomly select three abilities for you to help you survive in the pirate world."

The system quickly refuted him. How could it be that kind of person! It would provide what was necessary.

"Three abilities?"

"What abilities?"

"You said they were random, so why ask!"

"...."

Kaito now fully agreed that artificial intelligence shouldn't have feelings. He couldn't argue with it at all.

"Ahem! Okay, now let's start drawing abilities."

The system cleared its throat and formally began the ability selection. Kaito had no idea why a system would even need to cough.

In an instant, golden light erupted, and Kaito had no clue how he felt it with his eyes closed. It was like a dream, appearing directly in his mind.

"Three beams of golden light?"

"Is this the delivery? Golden legends?"

Kaito muttered to himself. The system ignored him, but the next moment, Kaito coughed up a mouthful of blood—literally a physical mouthful of blood.

"Congratulations! You've obtained the ability, 'Weak and Sickly' (initial incomplete version)!"

(For this, I should explain. Otherwise, many readers will think that being weak and sickly in the pirate world is trash. Kaito's Copy Fruit allows him to replicate others' abilities. For difficult techniques like Haki, he only needs to replicate it once, then wait for the feedback after some time to gain it. So, this greatly minimizes his 'weak and sickly' buff. Afterward, when he replicated Luffy's Haki and Garp's physique, he basically wasn't weak anymore. People say Kaito didn't exercise for years, but after going to sea, he suddenly wasn't weak anymore. With the ability to replicate and gain feedback, why would he need to train?)

The system's mechanical announcement rang out, and Kaito instantly felt as if a boulder had crushed his chest, spitting out a mouthful of blood as he embraced the sunlight.

He was so exhausted that he didn't even have the energy to curse at the system.

What the hell is this golden light? What the hell is this ability? Can't you keep this ability for yourself!!!

"And what does it mean by incomplete version?? Weak and sickly has an incomplete version? Why not just take me away in the full version?"

Kaito's mind was filled with curses and questions, but the system didn't care and continued its announcement.

"Congratulations! You've obtained the Devil Fruit: Paramecia-type Copy Fruit."

"This fruit allows you to gain the ability to replicate others' fruit powers and techniques."

"The true name of this fruit will… recover to its true name… once awakened… beep~~"

The second draw resulted in a Devil Fruit, which was indeed a local ability.

But as the system continued speaking, it sounded like a phone signal was breaking up, and finally, it just beeped repeatedly.

"What the hell?"

Kaito was utterly confused. What's going on? Did it get a virus?

But the next second, he was hit by a sensation of weightlessness, and Kaito fell freely.

Now, he couldn't keep his eyes closed.

Kaito suddenly opened his eyes.

It turned out Kaito had been lying in the air. Now, he saw blue skies and white clouds, the sun playing hide and seek behind the clouds while the clouds drifted like a sea of white.

It looked beautiful, but if Kaito weren't free-falling, he might appreciate it more!

"Damn it!!!"

A loud shout expressed Kaito's feelings, akin to ice cream that fell on the ground before he had a chance to eat it.
