"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!"

Bai Ye traveled to the world of “One Punch Man” and obtained the Mangekyō Sharingan and Double Kamui at the beginning…

During the Fourth Great Ninja War, when Kabuto unleashed the [Impure World Reincarnation] jutsu to summon fallen legends...

No—driven by sheer hatred, they defied the caster’s control and stormed off to hunt down that bastard streamer instead!

Kabuto: "What the hell?! Since when?!"

Itachi: "…Don’t tell me they’ve all mastered Izanami?"

(Comedy + Many Women + Invincible +????)

Chen Tian traveled through time.

No cheats, no system.

Oh, that’s not right.

He obtained two weapons that could transform his body, the Enma Sword and the Ryujin Jakka.

When he thought he could become invincible in this world and be feared by everyone.

But found...

There's something off about the people around him. Kitagawa Umi? Shinomiya Kaguya? Kato Megumi? Yukinoshita Yukino?

Is this...a world where anime and manga merge together?

What's up with these girls?
