One Piece: Empowered by Chakra, I Toy with Fire Fist Ace

Yunan brings a Naruto System to the world of One Piece and defeats Fire Fist Ace.

Yunan takes Ace's small boat and sets sail, founding the Mangekyo Pirates. Along the way, he rescues the mermaid Camie, and they head to the Sabaody Archipelago together. First, he visits Shakky's Rip-off Bar and uses the pressure of his chakra to intimidate the Straw Hat Pirates. He rejects the title of Supernova to their faces, declaring that if he is going to compete for anything, it will be the title of Pirate King. He also invites Nami and Robin to join him in front of everyone.

Saint Charlos, one of the Celestial Dragons, goes on a violent rampage in the street, and Yunan blasts him away with chakra. When he learns that Camie has been sent to the human auction house, he storms the venue, defeats all the guards, forces Saint Rosward and Shalria to their knees, crushes the explosive collar around Camie's neck, and takes her away.

Sentomaru and the Pacifistas arrive. Yunan punches PX-1 away, then severely injures Sentomaru with a Rasengan. Marine Admiral Kizaru appears soon after. Yasakani no Magatama and Morning Peacock collide in the sky, and Yunan then uses Amaterasu to make Kizaru retreat in alarm. After Rayleigh intervenes, Kizaru withdraws, and Yunan gains Lightning Release chakra. He will head to the New World next, while Marine Headquarters is already preparing to monitor him at the highest level.
