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.

I awoke from a dream, incomprehensible murmurs echoing in my ears. Forgotten myself, lost my past. Looking around, I realized I was in hell—explosions raged across the azure sky, bullets ravaged the streets like a torrent, and war burned constantly across this land. The aliens who lived here possessed seemingly fragile yet fearless bodies, forming gangs for their own purposes, killing each other day and night. Then, they discovered me. They called themselves students, told me this place was called Kivotos. They also called me—Teacher.

Aha, the star god possessing wealth, fame, and power, once said, "Want my treasure?" "Then go find it!" "I've left it all there!" Thus began the Age of Pirates! And our protagonist, Luffy, embarked on a series of exciting adventures! "I'm the Pirate King of the Universe!"

Good news, I've traveled through time. Bad news, I'm the only one in this world. Good news, I can create worlds at will. Bad news, everyone except me is an NPC. Good news, I can leave this world. Bad news, the plane crashed. Ye Zuochen didn't think it was a big deal; he could still steal the protagonist's chance to go to Sardinia and slay the gods. What? The gods are blocking the door! Now he can only cling to the big brother, that monkey. For the sake of being from the same hometown, please give your brother a hand!

My name is Ivan, a time traveler, male, with average combat power, and a talent for being funny. However, the mission requires me to kill the immortal demon king, so... I can only be a gigolo!

Selia: Damn it, why is it that every time I have these unnecessary emotions because of you?

flamme: Why didn’t you tell me earlier that you and selia had a child!

frieren: What exactly is this sour feeling in my heart?

frieren: Woohoo, I’m really not a big mushroom...

Aura: Loyalty!

(Not a crossover anime/manga universe, but set in the Akatsuki/Akame ga Kill! universe) "Ichijo, I bestow upon you the Imperial Arm Murasame to commemorate your achievements." "No, too much killing intent, it will harm my health." "What about the Demon Possession?" "No, Lancer's luck is E, how many masters has this thing killed?" "Gaia Foundation?" "I don't want to be a cross-dresser!" "Then what do you want? Tell me, and I will grant it to you." "I want the Demon God Manifestation!" "But, this Imperial Arm is on Esdeath, if you want it, wouldn't you be taking Esdeath home with you?" "Your Majesty is wise, I thank Your Majesty for the marriage!"

OVERLORD fanfic

As a newly returned supreme ruler, Alucard, by chance, traveled to a new world along with Ainz Ooal Gown.

They knew nothing about this completely new world.

How will Alucard, the top player who once dominated "YGGDRASIL", face the problems that follow?

How will Alucard, dubbed the "moving world boss" by his defeated adversaries, survive in this new world?

How can we resolve the conflict between the supposedly invincible True Dragon King and the Sky City left behind by the Eight Desire Kings who ended the Dragon King era?

Let's look at the detailed explanation in the main text.

[Anime Crossover] [2D] [Not a Single Heroine] [Infinite Flow] [Invincible, Slice of Life] [Slow Burn]

An inventory system is introduced at the start of the game.

An Xue: "What? You want to do me?"

"Let me ask about the anime-themed cookies in my hand first!"

"Red Eyes! Charge!"

Chitong: "...?"

"Esdeath! Bronya? Mebius?!"

"Go!?"

......

"Looks like I'll have to do it myself..." (sighs)

"Heaven, in motion all things!"

This book is a slow burn with a slice-of-life focus—you'll only get bored if you read it from beginning to end!

If you only read the first three chapters, you might as well play some poker with your buddies.

Confirmed worlds: [Main World Without Collapse (Merged World)] → [Akame ga Kill!] → [Main World] → [Kaguya-sama: Love Is War] → [Main World] → [Sophie] → [Main World] → [Spider Girl]

With a contract, Lin Qi became the sole master of "Hall of Valor" and gained the ability to travel through the heavens.

Every time he arrives at a new world, he will gain a top-level talent that is in harmony with the rules of that world.

[Demon Slayer]: You have obtained the talent [Transparent World·Extreme], and everything is visible in your eyes.

[Spell Return]: You have obtained the talent [Unlimited Spells], and you can manipulate space at will.

[Naruto]: He has acquired the talent [All-Seeing], which has chakra of all attributes and can instantly cast all kinds of ninjutsu.

When the world's activity reaches 30%, he can sign a heroic spirit contract with the powerful in this world and summon them to any world.

When the world's activity reaches 100%, he can anchor this world, turning it into his own backyard, and enter and exit it at will.

Lin Qi: "My goal is simple: to spread the glory of Valhalla to every world. All the powerful will be proud to be my Heroic Spirit!"

Using the Impure World Reincarnation technique, he was unexpectedly reincarnated into the world of One Piece, becoming the son of Dragon and given the name Luffy. Although the name is the same, his core has changed, and thus his path is different. He initially intended to skip the Devil Fruit and join the Navy, but after unexpectedly encountering the red-and-white-haired princess, he discovered how unfamiliar the world was. How can this be a movie world? How could my King Luffy possibly have a childhood friend and a romantic comedy?
