One Piece: Fists That Rule the World

In 2025, ordinary young man Li Xia accidentally transmigrates to the world of One Piece. In the body of an eight-year-old child, he awakens the Dungeon Fighter "Male Fighter" template. Starting with Striker, he steadily advances to the peak of Ultimate Striker. His skills may occasionally miss, but with his martial arts and the Three Types of Haki perfectly combined, he becomes the "Iron Fist Legend" of the world of pirates.

Knowing how the story unfolds, he first meets Luffy in Foosha Village in the East Blue and sets himself the goal of "becoming the strongest first mate." He accompanies Luffy as he gathers his crew: helping Zoro overcome his swordsmanship bottleneck, providing cover for Sanji's cooking on the battlefield, helping Nami avoid weather disasters, and protecting Chopper from cruel experiments. He also first meets Robin in Alabasta. His promise to "protect the truth of history" begins a bond that spans mountains and seas, and the two eventually walk down the aisle together.

From the Arlong conflict in the East Blue and the Buster Call crisis at Enies Lobby, to the passionate battles against their enemies in the Paramount War and the decisive fight against Kaido in Wano Country, Li Xia is always Luffy's most reliable right-hand man. He is a battlefield commander who dismantles enemy attacks with precise plans, the strongest shield who faces Admirals and the Four Emperors head-on with Ultimate Striker, and the emotional anchor of the crew, holding fast to his faith when Luffy hits rock bottom and giving Robin hope when she despairs.

When the Straw Hat Pirates reach Laugh Tale and Luffy becomes the Pirate King, Li Xia does not stop. Together with Robin, he deciphers the truth of the Void Century and searches for the Core of Light to fight the dark forces of the universe. From the blue ocean to the vast stars, he witnesses Li Nuo grow into a new generation of guardian, carrying the belief in "the bonds of comrades" and "protection by iron fist" from the world of pirates to every corner of the universe.
