One Piece: I, Uchiha Itachi, the Great Villain of the One Piece World

Jia You transmigrated to the world of One Piece and awakened a Hatred System. As long as someone hated him, he would receive a reward.

For the sake of those rewards, the main cast and the others have lived in utter misery ever since.

From the start, Yakushi Kabuto infiltrated the Straw Hat Pirates, then recruited the Third Raikage and Pain to block their way, making it difficult for them to set sail.

Luffy: That bastard not only dug out my eyes, he also killed all the villagers and even built a pigsty over their graves!

Zoro: Damn it, he actually blew up Kuina's grave!

Nami: So that bastard was the one who ordered Arlong to take over our village? That's unforgivable!

Sanji: That bastard stole our restaurant and burned it down. I'll never let him get away with it!

Usopp: He's a demon. It's bad enough that he bullied Kaya, but he even made his underlings line up. He's not human!

Robin: Every island Luffy and I visit, he reports us. The CP agents never stop coming. I've had enough!

Sengoku: Itachi is a good Marine!

But the next moment, Sengoku cried out in alarm: What? He deserted the Marines with his men?

Garp: I watched Itachi grow up, and he's my disciple too. He's not a bad guy… Before he could finish, Uchiha Itachi said he had something heartfelt to tell him.

Paramount War

Yakushi Kabuto: The truth is out. I've shed my snake skin and ascended to become a dragon!

Under all that pressure, the entire Straw Hat crew grew much stronger!

Luffy: Susanoo plus Fourth Gear. Zoro: Susanoo Three-Sword Style.

Usopp: Kamui!

Nami: Water Style: Who the hell built this dam!

Sanji: Eight Inner Gates! Open!

Five Elders: Why? Straw Hat Luffy has only been at sea for a few months. How can he have the fighting power of one of the Four Emperors?

Uchiha Itachi: Because I pushed him to it!
