Ryan, who survives by petty theft after transmigrating to the world of One Piece, looks at the Devil Fruit he just stole and says:

He who steals a hook is executed; he who steals a country becomes a prince… he who steals heaven and earth becomes a saint!

From now on, please call me the Demon Lord of the Heavenly Thief!

Wayne, who transmigrated into the body of a pirate, awakened the Good Citizen System.

Living in the world of One Piece, he must strictly adhere to the labor laws of his previous life, arriving at work and leaving on time.

As long as he strictly follows the rules, he will reap a bountiful harvest every day.

Physical fitness, swordsmanship, martial arts, and domineering presence.

Everything you could want!

And so began his unique path of law-abiding piracy and robbery.

...

Nine o'clock in the morning, starting a beautiful day.

Burn! Kill! Loot! (Omitted)

At 5 p.m., a busy day came to an end.

Go home! Go to sleep!

His brothers, looking at the city they had finally managed to conquer, were unwilling to give up and wanted to break the rules.

But after being educated on the law by law-abiding citizen Wayne, they could only follow him back with their faces full of embarrassment.

Before leaving, Wayne shouted to the townspeople, "Wait! I'll come back to rob you again at nine o'clock tomorrow!"

...

As time went on, Wayne's strength began to become unfathomable.

Due to his eccentric behavior, the Navy paid close attention to him but did not take him seriously.

Until the Marineford War many years later.

Seeing Wayne slice the entire Marine Headquarters in two with a single stroke, the Marines finally realized what was happening.

This little pirate they didn't pay any attention to seems to be a tiny bit stronger than they thought...

Whitebeard: "This is it!"

Ace: "Uncle Vegeta, save me!"

Warring States Period: "This is it, we're doomed."

Just when everyone thought the outcome of this battle was sealed...

Wayne: "I won't bother you anymore, I'm leaving now. It's time for me to go home."

Whitebeard: ? ? ?

Ace: ? ?

Gu Changtian accidentally travels to the world of One Piece and is bound to the One-Punch Man Summoning System. In the One Piece world, he establishes the First Legion and continuously accumulates shock points.

Such a terrifying demon has crossed over into the world of One Piece. What will become of the One Piece world...?

"The Warring States period was terrifying; the First Legion members were all like monsters..."

Whitebeard: "Giants are the strongest men in the world..."

Redhead: "Oh no, my pride isn't working anymore..."

Garp: "Even my iron fist can't beat the First Legion..."

Kizaru: "No matter how much money you offer me, I won't fight the First Army..."

Screen One] "Host, your fishing game today is pretty realistic. You start with one boat and don't even give me a paddle." "Hahaha, I'm done laughing! I think this is more like a survival game." Faced with the teasing from the netizens in the livestream, the host's face flushed, but he forced himself to remain calm. "Brother, trust me..." Before he could finish his words, a large ship approached from behind, its flag bearing a red skull. A tall man with short red hair stood at the prow, his black cape fluttering. "Want to be a pirate? My name is Shanks..." With a casual move, he slashed at the sea. In an instant, the sea split, resembling an abyss. [Screen Two] The world's greatest swordsman, Hawkeye Mihawk, shattered sixteen pirate ships with a single strike... [Screen Three] Red-Haired Shanks meets the world's strongest man. With a casual clash of hands, the clouds swirled back, and the sky crumbled!

Marinford...

"Gulala, Ace, are you okay?" Whitebeard stood at the bow of the Moby Dick and looked at the execution platform.

"Whitebeard! You've come as expected, and this time you're destined to never come back!" Zhan Guo shouted at Whitebeard.

"Oh? Going but never coming back? I'm afraid that's not up to you." A blond boy moved and appeared beside Whitebeard.

"Who are you?" Zhan Guo looked at Leiduo in confusion.

"Edward Reardo!" The young man waved his staff, creating a strange phenomenon in the sky and on earth.

"Gulalalala, let's have a big fight today, brothers!" Whitebeard activated the Tremor-Tremor Fruit, causing a huge tsunami.

Jiang Cheng accidentally travels to the world of pirates and becomes Luffy, the background king. Pirates seem like a good choice. The top thieves, the world's most powerful, where I am Luffy, the world is mine. My name is Monkey D. Luffy, and I shall crush all my enemies.

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

The boy died, the girl lived.

When I opened my eyes again, I was not in a white hospital room, but in a cold, dark space.

There is no sun here, no earth, only deathly silence.

He also noticed something was wrong with her; she seemed to have been reborn, and not only did she resemble Hoshimiya Rokuro from the anime Date A Live, which he had watched before, but she also possessed magical spirit powers.

At the same time, she discovered that he was dead, his body beside her. Although she could not sense any signs of life, she felt as if she were still connected to him...

Suddenly, hope filled the girl's heart, and she decided to seek the realm between life and death, embarking on an unknown and long journey.

Her first stop was actually—

One Piece, Akame ga Kill!, Naruto, Re:Zero -Starting Life in Another World-, Overlord, Godslayer, Jackie Chan Adventures (in progress)

P.S.: The good news is that the author doesn't know how to write romance; the bad news is that the author only learned how to write exciting battle scenes.

Traveling through the pirate world, he was swallowed by the King of the Sea at the beginning, and then awakened the god-level [Cube Fruit]!

Everything in the world can be decomposed and reassembled! Others work hard to develop fruits, I directly read the data and synthesize it with one click!

While the navy was still showing off their pacifism, my 100-meter Diamond Gundam had already been assembled.

Everyone thought I was adventuring on the Grand Line...

They don’t know that every time I arrive at an island, I copy the data of the entire island!

The Battle of Marineford breaks out, and the eyes of the world are focused on the execution platform...

I printed a "Sky Island" directly above the Navy Headquarters! ?
