    The protagonist is Akainu's nephew, possessing an Air-Air Fruit (likely a self-created fruit) that he has developed very well. Unless it's a high-level match, he relies heavily on physical combat. He's also absolutely righteous and has low tolerance for Marines like Garp whose allegiance is wavering. Note: the first few chapters might be a bit bland, and the time span and plot might be a little overwhelming, but it gets better as the main storyline unfolds. 👌

    💥 *One Piece: Ten Years of Developing the Worst Devil Fruit* | Turning a "trash fruit" into the ultimate weapon, he beat up a Yonko so badly his face swelled up! The protagonist starts by eating the "worst fruit," and everyone laughs at him, saying he'll be a weakling for life. But he spends ten years developing it—making the fruit's ability incredibly powerful! While others' Glint-Glint Fruit only allows for light-speed movement, his "worst fruit" can directly distort space, trapping Kizaru in a spatial rift with his light-speed kick! 💥 When fighting Kaido, he even used his fruit's ability to "fold" Onigashima, causing the Beast Pirates to get lost! This kind of ultimate underdog triumph is absolutely amazing for One Piece fans! ⚡ *Transmigrated into One Piece and Gained the Ability to Modify a Devil Fruit* | Devil fruits can be modified? Upgrading the Gum-Gum Fruit to "Steel-Gum," even Luffy would be envious! While others passively awaken their Devil Fruit abilities, the protagonist's "Modification Fruit" allows him to actively upgrade any Devil Fruit! 🌪️ He modified Zoro's Sandai Kitetsu, turning it into a "Dragon-Slaying Demon Sword"; he fused his Devil Fruit with Conqueror's Haki, creating attacks capable of tearing through dimensional barriers! Most outrageously, he even modified the Marines' Justice Cloak to automatically reflect attacks, making Akainu's magma fist feel like a tickle! This "everything can be modified" bug setting means he can roam freely in the One Piece world without anyone daring to challenge him! 🎮 *Urban Pirates: Invincible Starting with the Strongest Paramecia-Type* | Bringing a Pirate Fruit to the city, he single-handedly wipes out an entire gang!
