"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!"

Lin Mo reincarnates into the world of Fuyuki as the only Crimson Demon Clan member who can’t use magic. At twelve, he proposes to an evil god, and from then on begins his journey—rampaging through anime worlds alongside his evil god wife and his entire hometown!

Because of an accident, he accidentally became the tragic hero of the Re: Zero world, Natsuki Ang. He thought he was going to experience the tragic life of infinite death, but he got the life option system and got the Samsara Eye with the power of the Six Paths. Since then, the tragic hero who was full of regrets and pain disappeared. Instead, he was replaced by Natsuki Ang, the philanthropic immortal who beat Lai Aotian with his bare hands!

(Invincible at the beginning, a cool story) Ye Yu traveled to the world of pirates and activated the Overlord System at the beginning. He would become stronger by signing in every day and basking in the sun!

There is nothing that can't be solved by a little bit of Domineering Haki. If there is, then I will release 100 million points of Domineering Haki! Sorry, my Domineering Haki is only 100 million points stronger!

Red Hair: Don’t ever say that my domineering personality is too strong in front of Ye Yu again, I will get embarrassed!

Whitebeard: With Yohane, my Whitebeard Pirates are invincible!

Navy: Ye Yu is coming, retreat quickly!

Sengoku: Why would Ye Yu, who has such strong fighting power, become a pirate? There is no justice in the navy anymore, because victory is justice!

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!

He transmigrated into the world of Attack on Titan...

"Ding! Congratulations, you've picked up the Female Titan's power."

"Ding! Congratulations, you've picked up the Armored Titan's power."

"Ding! Congratulations, you've picked up the Colossal Titan's power."

Ji Yu feels that he might be the first man to possess the power of all Nine Titans since the Founding Titan.

Other worlds to be determined...
