After watching Greninja's crushing defeat against the Water Spray, Sun Wuming, driven to abandon the anime, travels to another world.

Having obtained the Zhutian Martial Arts System, he strives to become stronger, diligently training and finally mastering powerful techniques such as the Three-Color Haki and the Eight Gates Ninjutsu.

But when he finally mastered Kamehameha, believing he could survive in this world... you told me this is the Pokémon world!?

Sora Ayaka Zangmarant: "We became so strong because we were beaten so often by our master..."

Groudon Kyogre: "We thought the only one who could deal with us was that flying caterpillar, but that day, that human threw us, returning to our original form, into outer space..."

Arceus, watching Sun Wuming, covered in terrifying energy waves and his golden hair standing on end, transformed into a Super Saiyan, was completely shaken.

Kurozawa transmigrated into the world of One Piece. After dying once, he awakens the godly Six Eyes. By gaining bounty rewards, he becomes stronger. Upon check-in, he receives Advanced Haki (Baryu).

“Yo, long time no see! Your defeat was because you didn’t chop me into mincemeat!”

When the strongest modern man clashes with the sea's overlords—the Marines—who is truly the challenger?

Whitebeard swore: “The Marines are the challengers!”

Marco: “Will we win?”

“We will—because I am the strongest!”

During the Marineford War, without wasting even a second mourning Whitebeard's death, the one who rushed straight to the execution platform was the current strongest of the Whitebeard Pirates—no, Phoenix Marco!

Two years later, Fleet Admiral Sakazuki roared in rage: “A bounty of 1.5 billion

"That sword style should have been lost to history!!" — Muzan snarled in fear.

"Kamiya Seiichi… you're terrifyingly strong! Are they serious?! Gojo Satoru is the strongest in the modern era?" — Sukuna laughed hysterically.

"Rin, the Sword Saint Kamiya Seiichi is the mightiest Servant! Summon him and we shall win for sure!" — Tohsaka Tokiomi declared resolutely.

"He is the final destination of the sword in this world." — Dracule Mihawk muttered, watching Zoro step up to challenge.

"Eh?! This has to be a joke, right?!" — Kyoraku Shunsui whispered, sweat sliding down his cheek, staring silently at the two blazing Ryūjin Jakka blades.

Sword Saint. God of Cursed Techniques. Strongest Grand Servant. The Pirate Era’s Ender…

Kamiya Seiichi: "All of my strength comes from my own hard work, the system… and transmigration!"

In a single night, two great bloodline clans were wiped out, and Konoha issued an emergency notice:

Uchiha Itachi – S-rank rogue ninja, the infamous exterminator of the Uchiha Clan.

Hyūga Gakuya – S-rank rogue ninja, the infamous exterminator of the Hyūga Clan, who seized their bloodline inheritance.

Born from the union of a Hyūga and an outsider, Hyūga Gakuya was scorned as a disgrace and treated as a branch family servant. From a young age, he suffered constant oppression, and while he narrowly survived due to his inherited bloodline, even his closest relatives were relentlessly persecuted by the Hyūga main family.

Now, only one thought dominates Hyūga Gakuya’s mind—destroy the Hyūga! But his current strength is not enough; he needs more power!

…

Years later, Hyūga Gakuya annihilated the entire Hyūga Clan. Hundreds of Hyūga bodies vanished without a trace, all consumed as nourishment for his Tenseigan Awakening.

The ninja world lost a member of Konoha’s Anbu…

And gained a Hyūga unshackled from his chains—a ninja who defies the rule of the Great Nations!
