Naruto: From the Start, I Have an Ultimate Great Sword!

In the world of One Piece, Ye Ren studies under Mihawk and masters the true art of the swordsman!

On the day he graduates, he kills one of the Five Elders with his own hands and seizes the Supreme Grade Blade, First Generation Kitetsu!

But in his sleep, he transmigrates once more, this time to the Hokage world!

No-sword style, one-sword style, two-sword style, three-sword style!

Flowing Cherry Haki!

When three swords appear in Ye Ren's hands, the ninja world gains a monster who can dominate the battlefield with nothing but sword strikes!

“To be fair, he sliced through my Susanoo armor with a single slash!”

Madara Uchiha gives a wry smile.

“Umm...”

“Actually, my Sharingan can't see through his sword at all.”

Uchiha Itachi shakes his head.

Ye Ren grins confidently.

“My sword cuts through anything!”

“Nine mountains and eight seas make one world. Gather a thousand worlds, and they form a ‘Lesser Thousand World.’ Multiply that world by three, and nothing in existence can withstand my blades. Three-Sword Style Secret Art... Great Three Thousand Worlds!”
