Ghost Shark, a deep-sea hunter, is reborn into the world of One Piece as a Marine. She eats the Bat-Bat Fruit, a Mythical Zoan type, and transforms into a vampire, becoming an undisputed vampire girl among the female soldiers. As her fame rises from eliminating pirates, more and more women surround her.

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!

"Is there something wrong with the story of an ordinary person like me being reborn as a character in One Piece, only to be born on a ship and shipwrecked, ending up on Elbaf Island?" "What?! I transmigrated too early!?" — (Multiple female leads, no system, single world, multiple transmigrations)

My name is Bai Ye. I run a small stall in Windmill Village and work part-time as a dimensional intermediary.

One day, the naval hero Garp complained that my senbei was awful and tried to overturn my stall.

I threw him into the otherworld instance!

[Ding! Client selected: Monkey D. Garp!]

[Dungeon generating... Dungeon World: Naruto!]

[Mission Objective: Survive the Third Raikage's offensive, or defeat him!]

Garp: "You brat! What kind of hell have you brought me to?!"

Me: (Legged back) "A VR experience for one million Berries, what a steal!"

[Ding! Dungeon cleared! Clearance rating: S+!]

[Congratulations on obtaining the SSS-rank reward: The Perfect Jinchuriki of the Eight-Tails!]

[Congratulations on obtaining the S-rank reward: Lightning Release Chakra Mode!]

Feeling the surging lightning and tailed beast chakra within my body, I laughed out loud.

Who should be thrown in next? Whitebeard? Or one of the Five Elders?

(No way, letting others fight to the death while I get the rewards? This system is too awesome!)

Link, transported to the world of One Piece, brought Doraemon's magic pocket with him. He happened to run into Luffy, who was still using the Gum-Gum Fruit and hadn't yet awakened his true power as the Mythical Zoan type, Sun King form. So, I'll follow this future Pirate King, the liberation warrior Joy Boy, the future Sun King, and experience the magnificent world of One Piece together! During their journey, various gadgets in Link's hands will demonstrate their powerful effects! Luffy, did you know the Gum-Gum Fruit has another name? Hawkeye, you're the world's strongest swordsman? How about the [Famous Sword - Lightning Bolt]? Kaido, you have the strongest Zoan-type army? I have some delicious [Momotaro Rice Balls] here, you can try them! Im, you want to destroy the world? Here's the [Earth Destruction Bullet], do you want it...?

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")
