While other transmigrators were still diligently practicing ninjutsu, Izumi Masamune had already turned the Naruto world into a strategy game with the help of the system—wait, who says saving the world and falling in love can't happen at the same time?

Reincarnated as Hyuga Neji, he awakens a cross-dimensional system. Free from the constraints of the Caged Bird Seal, he's given the "blessing" of endless evolution and random missions. He punches the Otsutsuki, kicks the Five Kage Summit, and effortlessly maxes out Hinata, Kurenai, and Anko's favorability? But just when he thinks this is just a typical action-packed leveling-up story, the system prompts: "[Contractor can be taken to the main world]"—Wait, am I saving the ninja world?

The leaves of Konoha still dance in the air, but the real storm has only just begun. When the genius of the Hyuga clan unveils the truth about Kaguya, when the light of the contractors transcends dimensional barriers—are you ready to embrace this chaotic yet addictive Naruto world?

He died unexpectedly but was blessed by Mother Earth, gaining the ability to travel between worlds and special bloodline abilities. After laying the foundation for becoming stronger in the world of Rurouni Kenshin, he arrived in the world of Highschool of the Dead.

Faced with characters he admired in his past life, Li Hao naturally hoped to change their future fates rather than let them struggle in the apocalypse.

In the world of Kill la Kill, witnessing the decaying empire and the suffering of its people, he has a new goal: to overthrow the empire and, at the same time, change the tragic fates of the girls.

In the Fairy Tail world, learn amazing magic, build a unified empire, and see what these so-called gods really are and why they can curse mages.

Other worlds are yet to be determined...

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")

Unexpectedly arriving in the world of Naruto, Uchiha Chiren desperately trains to save his life. He nearly escapes assassination after calling Danzo a eunuch and is sent to the battlefield as cannon fodder. Fortunately, he awakens a system that allows him to choose an ability from his opponent after each battle. [I choose Uzumaki Physique] [I choose Spirit +1] [I choose Constitution +1] [I choose Eight Gates Ninjutsu!] [I choose Flying Thunder God!]... Initially, Shimura Danzo was ecstatic, hoping this second battle would end Uchiha Chiren's fate. Unexpectedly, all his previous machinations proved ineffective, and Chiren even managed to activate his Mangekyō Sharingan. Years later, Chiren stands in the Hokage Building, addressing Shimura and the Sarutobi clan below with a hearty laugh. "Shimura Danzo, Sarutobi Hiruzen, this is your teacher, Senju Tobirama, right? Look! Today...

Sengoku: "Hey, Heya, what's this? You're joining in the fun too? What a fitting ally!"

"Ah, Marshal, you've misunderstood. We're not like that," the person whose name was mentioned stroked Perga's mane and responded with a chuckle.

"Oh? So you are... This isn't a place where you can change your mind based on the wind."

Sigh—Heya was a little helpless.

Sure enough, it must be because of the beard!

Heya: "Are we really that different? You have to take some responsibility for that, Dad—"

"Gurararara, isn't it great that you look like your mother?" The white-bearded man couldn't help but laugh out loud as he glanced at his youngest son, who was leaning closer with a resentful expression.

navy:???!

………

"Oh well, I'll just introduce myself anyway."

Edward Hea

"This is my name."

...

P.S.: I recently got hooked on One Piece, and my brainstorming session with friends about how the Whitebeard Pirates could continue to exist at sea led us to the conclusion that they needed a successor, haha.

P.S.: I really like mystery and always wanted to write related fanfiction, but I ended up in the One Piece fandom, so this strange stuff came out. (Private message: Masai, wadsweetie, it wasn't intentional.)

Loya was incredibly frustrated. Ten years ago, he had just transmigrated and hadn't even declared his arrival. He casually rescued a little girl named Nico Robin who was being hunted. He thought his life would be spent hiding with this "devil's child." Unexpectedly, ten years later, when she found the first Poneglyph, he "awakened." "As long as I touch something that carries history, I can turn its contents into reality." When I touched the stone tablet recording the legendary Devil Fruits... —[Obtained Zoan-type Human-Human Fruit, Mythical Zoan, Final Form (Unawakened)] When I touched the stone tablet in Alabasta recording the Ancient Weapon Pluton... —[Obtained "Pluton Blueprints"] From then on, things started to spiral out of control.
