(Smart general + invincible + reasonable plot + no collapse of combat power)

After defeating Kabuto Yakushi and lifting all the Impure World Reincarnation of the Fourth Ninja World War, Itachi, who was burdened with countless darkness and contradictions, completely conveyed his will and love to Sasuke and left the ninja world without any regrets.

But just when Itachi thought that everything was over, he regained his 18-year-old body and came to the bottom of the Sabaody Archipelago in the pirate world!

"The Age of Discovery? Thousand Sunny?"

"You want to go to Fishman Island, 10,000 meters below? And find the end of the Grand Line?"

"You want me to be your companion?"

Luffy smiled and waved at Itachi: "This is truly a fate given to us by God, Tear Groove Man, you must be my partner."

Zoro: "Although I don't know this guy's origins, he is quite reliable."

Robin: "I am very interested in him. Maybe he is carrying a destiny that he himself does not even know about."

Akainu: "K-sou! Put a bounty on that man. Itachi Uchiha's head is worth at least 3 billion!"

Garp: "Hahahaha, I don't know where this guy came from, but the giant he summoned is really cool."

(No system, pure pirate flavor)

My name is Michael, and I was reincarnated into the world of One Piece.

He ate the Human-Human Fruit, the Mythical Beast, and the Seraph Form, and became a marine.

I thought I could survive till the end...

But unfortunately, it is impossible for me to be a dog for the Celestial Dragons in this life.

At this point, if you don't want to accept your fate, the only option is to rebel.

But when it comes to rebellion, of course it would be more exciting only if the whole world is involved.

"Monkey D. Dragon, the Self-Defense Army has no future. Change the name to the Revolutionary Army and join me!"

"Kozuki Oden, do the chicken feather dance, backstab Kaido and then come with me."

"Pluto Rayleigh? I have a project called Cross Guild. Are you interested?"

"Well, Whitebeard, Charlotte Linlin... How can being a pirate be as exciting as being a king?"

"Fish-Man Island? I'm protecting Fish-Man Island! I'll fight anyone who touches my special economic zone!"

……

Michael:

"You know what, Celestial Dragons? We are going to start a super-cool rebellion. All the big names will participate. Do you know who the target is?"

"It's you~"

After crossing into Brook who was still in hell 52 years ago, he was successfully resurrected!

What?

Charlotte Lingling is just a 16-year-old homeless pirate?

Received!

Edward Newgate is only 22 years old?

Still in a pirate group?

Received!

Red Earl Redfield followed?

Take it, take it all, and go to the Vodka Kingdom to find Kaido... Take all the strong men of the next era for me!!!

Transported to the world of ONE PIECE, and becoming Luffy's elder brother, Monkey D. Summer, from a young age follows Dragon around the globe spreading revolution.

At sixteen, Summer leaves the Revolutionary Army, sailing the seas solo and recruiting partners to establish the Smile Pirate Crew. Quickly capturing the attention of the Marine with his youth and strength, Summer is soon invited to become the youngest Shichibukai in history.

Sengoku: In the end, we entrusted the wrong person. Who would have thought the revolutionary ideas of the world's most notorious criminal, Monkey D. Dragon, originated from Summer, and to think Summer is your grandson, you scoundrel Garp, indeed the source of all this chaos is you.

Garp: (* ̄rǒ ̄)

Tsuru: I never expected such a smart child to be Garp's grandson, what a surprise it is. Who could have thought that the world's most peaceful nation is governed by a Revolutionary Army, truly a massive irony, sigh!

Garp: ฅ(TᄉT)ฅ, Little Tsuru, that hurts.

Akainu: Compared to pirates, Summer, who possesses the evil bloodline of the Revolutionary Dragon, is much more menacing, he must be dealt with immediately!

Summer: Ha, just you, magma dog? I'll knock you out with one punch!

Kaido: Even I have to yield under Summer's iron fist, this guy is absolutely inhuman.

Summer: Of course, I aspire to be the One Punch Man of the pirate world.

Whitebeard: Truly the new wave overtakes the old, the title of the world's strongest man has changed hands.

Summer: Hehe, low-key, low-key, it's just an empty title. (⑅˃◡˂⑅)
