One Piece: Starting with Sharingan, First Mate Uchiha

[Following the ship] [Naruto system] [Action-packed and exhilarating] [Multiple female leads]
When Victor woke up, he found himself stuffed into a barrel of wine.
Even more outrageous, a boy wearing a straw hat was sleeping in the wine barrel next door.
"My name is Luffy, and I'm going to be the Pirate King!"
At the same time, Viktor successfully bound to the God-level Naruto System.
Start with the Sharingan, switch ninjutsu at will, and unlock bloodline limits, Mangekyou Sharingan, Susanoo, Rinnegan...
Thus, the Straw Hat Pirates gained a vice-captain whose style was completely out of place.
Nami: "Viktor, you bastard!"
Robin: "First mate, the secrets you hold seem even more interesting than the Poneglyphs."
Kizaru: "Ninjutsu? What a terrifying ability."
Akainu: "You mere pirates dare to stand in the way of absolute justice?"
Viktor slowly raised his head, his scarlet eyes swirling wildly, and his complete Susanoo rose from the ground.
Have you ever seen the Uchiha clan at their peak?
When Susanoo descends upon the sea, when the Rinnegan surveys the entire new world—
This time, the adventure will leave no regrets.
And on Luffy's path to becoming the Pirate King, there will always be a strongest Yonko commander standing by his side!
