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")

(No system + no group + violent aesthetics + Momo-Momo Fruit + old-era powerhouse + semi-invincible + pirate style)

He is the most monstrous genius in naval history, possessing innate Armament Haki.

He is the captain of the 7th Division of the Rocks Pirates, and a world-renowned dual-wielding swordsman.

When the souls of 21st-century youths merge with Luffy's, the world begins to change! He bravely battles crocodiles in Alabasta, confronts his nemesis in Mogu'town, and challenges gods on Skypiea… (The synopsis is insufficient; please read the full text.) Multiple female leads + fast-paced, action-packed story + plot summary: The first few chapters are virtually identical to the original manga! If you remember the manga, you can skip directly to the fight against Crocodile; the previous chapters are simply a recap of the original. The only advantage is that you can watch at least 50 minutes of plot in 5 minutes!

In the era of Lox, a time of warring states and legendary tales, a 15-year-old boy named Pegasus, harboring unknown ambitions and wielding a blade called Wind Chaser, embarked on a turbulent journey.

[One Piece + Nami (female lead) + crewmate + Morax template + time travel]

Zhongli travels to the One Piece world and merges with the Morax template.

It can manipulate all rock elements.

He then joined the Straw Hat Pirates.

"Zhongli, save me!"

After Zhongli reversed his shield, the Straw Hat crew said:

"Zhongli's shield is truly reassuring!"

I was transmigrated into the body of a Mythical Zoan-type Devil Fruit user?

Before her consciousness was devoured by the consciousness of the Yamata no Orochi Fruit, Xia Lin awakened the Satan Soul, a receiving magic from Fairy Tail that allows her to receive demons.

Xia Lin stated that Devil Fruits are also a kind of devil!

He began by receiving the Yamata no Orochi fruit and became the ruler of Wano Country!

"Wano Country? That name is awful. From now on, this country will be called Inazuma!"

...

Forty years later, when Solo stood before Hawkeye, covered in wounds, he couldn't help but ask:

"A man like you isn't the world's greatest swordsman..."

"You frog in the well, have you ever heard of the 'one-cut wonder' technique?"

Transmigrated into a villainous lord in an action-adventure eroge? And destined to be used as a satisfying moment by the hero? No matter how you look at it, this is hard to accept! Fortunately, the Bilibili app arrived along with it, and from then on, Link could extract all sorts of beautiful girls from various 'doujinshi worlds'... Agnes from *Red-Haired Demon God*, Kim Mi-ting from *Brave New World*, Hannah from *Teacher's Grace*, Irene from *Twilight Prostitute*, Stella from *Warrior Dogeza Hypnosis*... and various elves, beast-eared girls, maids, princess knights, anti-demon ninjas... If he had these beautiful assistants helping him in various places, then everything would be fine! With these, he could live well in this other world, develop his own territory, create his own paradise, and change the game's inevitable death ending! Just when Link had fully developed and was ready to compete with the hero, the result... What? You're telling me the hero is a woman?! (P.S. Note before viewing: All the doujinshi used are rated 90 points or higher by the author, so you can enjoy them without worry. No characters from domestic secondary games are included to avoid backlash. Characters from single-player games or games like League of Legends can be considered if desired. That's all!)

You must first hone your skills until they are as refined as Scáthach's; you must train your physique until it is as powerful as Typhon's; then, you must lift the sword left by the King of Britain, mount Pegasus given to you by Medusa, and set off for distant lands; along the way, you will breathe fire and unleash thunder; people will weave your name into songs and sing them, their voices trembling in the night. You will become a legend, a walking—Heroic Spirit. …“Becoming a Heroic Spirit only requires three steps: close the book, open the door, and then go out.” With these words, Shane, carrying the Book of Heroic Spirits that could summon countless legends and myths, arrived in the world of Fairy Tail. “Hmm, out in the world, let's slay a dragon first!” (PS: Even those unfamiliar with Fairy Tail and Type-Moon can easily read this; enjoy! QAQ)
