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!

[Endless battles, sea supremacy, aim for the strongest]

If Blackbeard had taken Luffy's Nika Devil Fruit, Ace had been rescued, and Whitebeard hadn't died at Marineford, what would the future of the world have been like?

On the eve of the summit, an unlucky soul who had traveled from another world was devoured and merged with Douglas Barrett.

The lives of the devil's heirs took a different turn from that point on.

"The Paramecia-type Fusion Fruit allows the user to arrange and combine any object, causing them to fuse. It can also fuse any inorganic matter it touches with its own body to create desired transformations!"

Cells can arrange and combine to become ultimate life forms, ever-changing!

The arrangement and combination of matter—this world is a sandbox game in your hands, and you are the creator!

Microscopic particles arrange and combine, hand-crafted nuclear fusion, devastating the world!

Impel Down is in chaos, a mad dragon emerges from the abyss, turning the entire Deepsea Impel Down into a ship to fight on the summit!

In the Marineford War, a Gundam was launched, and Marineford was sunk with a single shot!

In the new world, we will conquer all and let the name of the Demon God resound throughout the seas!

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!"

It is easy to kill but hard to save people, damn, save, save, save.

Yeah, the magnetic field rotates one million Jesus Save the World Fists!

In this world, what else can resist Tang Ansheng from saving people?

Nothing, absolutely nothing!

Traveling through all realms, using crazy methods, igniting the spark of salvation!

This is a story about a superpower traveling through all realms. Taoist Ansheng's daily life is to save people and on the way to save people!

(No system, Saber-biting Tiger start, genius build)

The protagonist is reborn as Rufus, one of the five strongest warriors of Saberbite, a bard singing under the red moon.

He's the one who uses memory-shaping magic, the one who got knocked out by Gray in the Grand Magic Games arc.

If you're tired of joining Fairy Tail guilds, why not try something different here!

(Hello everyone, please call me Copy Ninja Kaka... wrong, please call me Fairy Tail's number one technician Rufus!)

(The protagonist's main magic skills: Time Annihilation Magic and Memory Shaping Magic.)

(PS: A completely new storyline; the protagonist will become the second Magic King.)

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.

People are in the world of Shrouding the Sky and traveling through all the heavens and worlds at the same time.

The fusion of talent and understanding allows for infinite superposition of combat power.

My combat power is five times that of my peers. You say I am just an ordinary person, but I won’t argue with you.

When my combat power is ten thousand times greater than yours, what should you call me?

O me of all the heavens and worlds, lend me your vitality!

(Including novels, animation, movies, and TV worlds)

At Hogwarts, who broke Snape's virginity?

In One Piece, why were Garp and Sengoku forced to dress as women?

Amidst the death, how did the bee escape from the airport?

Please look forward to the protagonist's crazy journey in various worlds!

The world is tentatively Harry Potter, Naruto, One Piece, Bleach, and One Punch Man

【System + Naruto Fanfiction + Not Brainless + Vest + Realism】

Zheng Dongfang travels to the world of Naruto, using the alias Dongfang Zhen. He gains access to a system called "Daily Card Draw," where he can gain access to all the abilities of a ninja, including chakra, ninjutsu, taijutsu, and even bloodline limits! Reaching a certain number of draws fully unlocks the corresponding ninja card, granting permanent ninja abilities!

Dongfang Zhen: I want to create a new ninja world, let me draw out Madara and the First Generation!

The three-year period has arrived, welcome the ancestor back!

Hyuga Tenkyō is a recognized genius of the Hyuga clan. He could recognize a thousand words at the age of three, recite ancient poems at the age of five, was familiar with the theory of ninjutsu at the age of seven, and created his own soft fist and Tai Chi at the age of nine!

However, when he was twelve years old, Hyuga Tenkyō was unable to even refine chakra. Every time chakra was refined, it disappeared into thin air. Not to mention ninjutsu, he couldn't even use physical techniques.

After being stuck in the Genin graduation exam for three years, Hyuga Tenkyō suddenly found himself as a Jinchūriki, and the tailed beast in his body turned out to be the legendary ancestor of chakra - Kaguya Ōtsutsuki!

Let me be frank. I will stop pretending. I am Kaguya Ōtsutsuki’s Jinchūriki!
