When the socially awkward former Water Pillar Tomioka Giyu suddenly travels to the world of One Piece and is forced to bind to a baffling "Interpersonal Communication Manual" system, witnessing the Straw Hat Kid on the execution platform, about to be executed by Buggy, saving him, breaking the platform, and becoming entangled seem like the natural progression. Luffy: "Wow! What a cool move! Be my partner!" When the taciturn Giyu encounters the most free-spirited pirate group, this sea is destined to be turbulent by the least chatty swordsman. ... "Let's have a party, Giyu!" [Interpersonal Communication Manual] [Target: Monkey D. Luffy] [Status: Extremely Excited] [Preferences: Throwing parties, hanging on to the host] [Suggestion: ... (Analysis impossible)] Right now, that rubber boat captain is swinging from my only arm. What should I do now...

Liu Yishou accidentally drifted into the world of pirates and obtained a strange pentagram array that could summon characters from another world.

His first partner turned out to be Wolf!

From now on, he will take Gray Wolf and other companions to travel freely in the world of pirates.

Su Chen, transported to the pirate world with a magician's legacy, learns most of the magic before encountering Luffy, newly at sea, and accepts an invitation from the future Pirate King. How will this dazzling and magical magic collide with those wondrous Devil Fruits? Nami, let me strengthen your Wind Magic! Usopp, would you like to learn about the Magic Bow and various attribute ammunition? Sanji, would you like some premium ingredients from around the world? And invisibility magic? Hey, Robin, everyone has their own purpose. If you don't even have the courage to try, you don't deserve happiness! Would Luffy and the others, strengthened by Su Chen, still have to watch Ace being killed during the Battle of Marineford? All regrets will be made right!

【Follow the ship flow】【I am a navy all by myself】【System】

Ike, who was thought to be able to persuade Luffy to give up being a pirate, got on Luffy's ship instead. The worst thing was that he awakened the Justice Navy System. Fortunately, there was a letter of appointment from the Private Navy given by Garp, which turned all the just deeds done by the Straw Hat Pirates into the achievements of the Private Navy.

Arlong: So what if the Straw Hat defeated me? I'm still wanted.

Ike: Huh? We're a civilian navy, just flying the crossbones. Why are we wanted? One phone call and the warrant is immediately rescinded.

Crocodile: The Straw Hat Pirates are also in Alabasta, why doesn’t the Navy arrest them?

Navy High Commander: Hmm? They're a civilian navy, not pirates.

World Government: The Straw Hat Pirates destroyed Judicial Island and were immediately arrested.

Ike: Who said that? It was Spandam, that idiot, who pressed the Golden Den Den Mushi and destroyed Judicial Island. Our civilian navy was only there to eliminate Spandam, the culprit who destroyed Judicial Island.

In the era of pirate riots, who is the real overlord of the sea?

The four emperors standing at the top of the pirates?

The mighty Qiwuhai?

A revolutionary army that emerges from the strong?

Or the navy that suppresses the sea?

No, not at all, there is only one real overlord of this sea.

"That's me, Fire Dragon Kahn!"

Kahn's life creed is: "As long as you pay, this old man can perform a hand-splitting dragon man!"

Kahn, formerly known as Xu En, has traveled through pirates for fifty years, and has become a vice admiral from a small soldier with his own efforts.

Kahn, who is already seventy-two years old, is getting old and is no longer in peak condition. He spends his days leisurely in the East China Sea. He has even submitted his application for retirement, and he is ready to die until his own life ends.

Congratulations to the host for reaching the system opening conditions, and the super money system is loaded!

The sound of the system interrupted his plan.

Kahn: "Can you buy life?"

System: "Yes, a portion of the water of life can restore the host to its peak state."

Kahn: "Is it possible to live forever?"

System: "Yes, a portion of Eternal Water can completely free the host from the restriction of life."

"Are there any devil fruits?"

"have!"

Kahn was instantly overjoyed.

"Hancock, wait for me, I'm just old, not dead!"

But then Kahn was taken aback.

"How much are these two things?"

"The water of life is 20 billion Berries, and the water of eternity is 500 billion Berries."

Kahn:? ? ?

Then, looking at the oil and water that I had worked hard for several years, the feeling of satisfaction disappeared instantly.

In the end, he decided on a goal, first earning 10,000 small goals before considering retirement!

When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

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! ?

Lu Ming used to regard the Celestial Dragons as termites and scum. When he traveled to One Piece and became a Celestial Dragon, he found that being a Celestial Dragon was really nice. He could drink the best wine, play with the best women, and command the admirals to come and go at will. The only thing that made Lu Ming dissatisfied was that there were too many people sharing power with him. So Lu Ming sprayed his hair with hairspray and stood in the sky of the holy land of Mary Geoise: "This world only needs one Celestial Dragon!" PS: More women, more Celestial Dragons

Transmigrating from birth into the world of One Piece, he became the World Government’s strongest talent in 800 years: the CP9 killing machine, Rob Lucci.

By all rights, this should have been the ultimate overpowered transmigration. But thinking of his future self—first sent to work as a shipwright in the trenches, failing the mission, then treated like a roadside nobody, and finally returning as a king yet still mocked as “the Ultimate Brother” by the world—Lucci felt his prospects were completely doomed.

Fortunately, fate is fair. After enduring a hundred blows from Kaido, destiny finally took a turn.

“Kid, come aboard my ship and become my crew!” The Governor of the Beasts, the strongest creature, and one of the future Four Emperors—Kaido—laughingly extended his fist toward the young Lucci.

Thus, boarding the Beasts’ flagship, Lucci proved to the world the true worth of the strongest talent in 800 years.

He faced Red-Haired Shanks head-on with fierce dominance.

Duels with Mihawk in swordsmanship.

Brawled with Garp in hand-to-hand combat.

…Years later. On a calm day, the newly set-sail Merry welcomes a legendary man aboard.

“Want to become the Pirate King? Fine! Survive, and I’ll let you be!”

The protagonist, Dicas, is transported to the world of One Piece and becomes a stray cat. Just when he is lamenting the tragedy and helplessness of life, the strongest cat god system descends. Watch how the protagonist improves his strength, how he uses the system to summon cats from the anime in his memories, and how he leads them to make a name for themselves in the sea world and make a name for their cat clan.

Rainbow Cat: "Let me, Rainbow Cat, the greatest swordsman of the cat clan, learn about the swordsmanship of this world."

Doraemon: "Rainbow Cat, wait a minute, let me get out the Lightning Ball to help you."

Dorami: "Wait a minute, brother, watch me use the shock gun in my left hand and the air cannon in my right to help you."

Meow: "I can do anything except catch Pikachu."

Talking Tom: "Me too. I'm invincible except for catching Jerry."

Star Cat: "Come and experience the charm of martial arts, magic, and wisdom. Here I come."

Abu: "Let's forget about the above. How about I show our enemies what the combination of technology and strength really means?"

Stingy Cat: "Come and experience the power of this Cat King's Explosive Red Fang."

Black Cat Sheriff: "I bet your bullets won't curve."

Blue Cat: "Hehe, do you know why I'm the leader of the Dragon Riders?"

Gatomon: "Let me destroy you in the name of the angels."

Tomorrow's Bright Moon: "We, the cat clan, will remove all obstacles."

Xiaoqing: "Let me tell you what it means to overcome strength with softness?"

Sugar: "Do you know what it means to break through force with speed? It's simple, just let me eat my fill of fish balls."

Whirlwind Claw: "I am the number one constable in the world."

The world of One Piece is silent and shocked.
