See All Swords, I Awaken the Thunder Sword Path

Ron transmigrated to the One Piece world, only for his system to vanish without a trace—leaving him a divine eye that sees through every sword art in existence! Watching Zoro’s duel alone granted him foundational mastery of the sword. Koshiro, Mihawk and Shanks were all utterly awed by his talent. He later obtained the Rumble-Rumble Fruit, forging his blades with lightning. His sword roars with thunder; every slash wails like ghosts and gods. No stats panels, no cheat buffs. One glance lets him comprehend all swordsmanship under heaven; a single strike shatters every technique in the world. He reigns supreme across all the seas!
