[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!

What kind of collision would occur in the Naruto world if someone obtained a Fruit of Ope Ope no Shit (without the weakness to seawater), a fruit that consumes stamina, and a Saiyan-like physique?

My name is Bai Xing. I was playing a game and I was transported to another world. Luckily, I was able to travel back, and I even activated a magical system.

Main quest: Survive until the final chapters of Shippuden.

award:

First, he could choose to stay in the present world and obtain a noble black card containing a billion dollars in legal and compliant liquid funds;

Secondly, he can obtain the character's peak strength and travel to other worlds he wishes to go to, or stay in this Naruto world to continue living.

For a modern person, neither choice would be a loss, but for someone who has spent half a month and three years in the "Second World," only one option remains:

—I need to find another world, I need to make a quick getaway!

The mysterious transmigrator, Isayama Yuki, avoided Nawaki's inevitable death due to his close relationship with Tsunade… but he never imagined the price would be his own. Fortunately, his timely refreshed [skill] allowed him a second chance. In the first week, his vision gradually penetrated the matter before him; to avoid eye strain, he could only gaze at the sky at a 45-degree angle… In the second week, he saw that everyone had a number above their heads. However, compared to exploring the meaning of these numbers, he felt this ability had another use… Hey, Mr. Hatake Sakumo, you're indeed skilled at concealment, but the number above your head is just too conspicuous!!

Mom and Dad aren't home. I'm all alone. Lonely and passionate. Suddenly, I get a crossover anime chat group where I can chat with anime girls. But why did it turn out like this? Homura Akemi: No!

[Dual protagonists: a transmigrator and a native protagonist + ensemble cast + Warhammer Fantasy + Naruto + multiple worlds]

In the Warhammer Fantasy world, amidst the death crisis of Krich Kenpi, the Gutter Hoarder (the protagonist, a transmigrator), he and Quake transmigrated a second time to the Land of Rain in the Naruto world.

Quake's forces clashed with the protagonist. Fearing for his belongings, the protagonist begged Quake for mercy, offering to give him a life-extending ring that would extend his life by twenty years. Quake, persuaded by the head of one of his favorite green-skinned enemies, which was stuck in his back (according to the official novel, Quake is extremely eccentric and talks to the series of dead heads on his back, using them as his advisors), temporarily spared the protagonist. Especially since the smell and feeling here were off, and only a portion of his Red Guard remained, Quake had a very bad feeling.

The protagonist didn't immediately recognize that this was the world of Naruto, since he couldn't understand the language of this world. After learning the language of the humans in this world through magic, he heard the Land of Rain, the Land of Fire, and Konoha, and then he confirmed that he was in the world of Naruto. However, he still didn't understand why he had traveled here a second time.

However, not long after, he met the Reincarnators and gradually understood everything.

The Skavens must take their place as reincarnators, or death will be inevitable.
