One Piece: I Talk Luffy into Enlisting, Change the Plot, and Grow Stronger

He transmigrates into the world of Pirate King, before the story has even begun, and awakens a Rebellion System. “I’m going to become a Marine Admiral!” 【Congratulations on successfully changing Luffy’s ambition. Reward: 1,000,000 Rebellion Points.】 “The young master is fighting the master! Who should I help?” 【Congratulations on successfully turning Kizaru against his allies. Reward: a random Logia Devil Fruit... Congratulations, you’ve obtained the Dark-Dark Fruit.】 As long as he changes the story, he can grow stronger! I will completely rewrite the world of pirates! (An invincible protagonist. He isn’t a bleeding-heart do-gooder, but he isn’t a villain either.)
