Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

Knowing the plot but lacking a system, he only wanted to remain a nobody. He even prepared in advance to learn about governance as a way out, hoping to take his parents away before the night of the extermination.

Unexpectedly.

Danzo captured his parents in order to collect Sharingan eyes, which caused Uchiha Jin to awaken his Mangekyou Sharingan on the spot.

A routine "time travel" accident caused Ash's human soul to be directly stuffed into the mechanical body of the Ex-Machina.

Just as he was happily preparing to go to the capital of the human race, Elkia, to find the two Blank siblings and get to know them, he looked at the sky above his head, which was covered by "spiritual corpses" and no sunlight could be seen.

Looking at the group of Skywings who were releasing Sky Strike recklessly.
