Transmigrated into the chaotic world of pirates, Lord Sima Di awakens a terrifying cheat: the Spirit Word ability, allowing him to alter reality simply by speaking. Arriving just in time for the iconic execution of Monkey D. Luffy in Loguetown, he leverages his knowledge of the future to trigger a unique Check-in System.

By recreating or interfering with famous scenes, he harvests overpowered rewards ranging from lightning immunity and peak mortal wisdom to luck-altering halos. As he effortlessly dismantles Marine Captain Smoker's defenses and reshapes Devil Fruit rules with a single command, Sima Di finds himself thrust into the center of the Straw Hat Pirates' journey. With the Revolutionary Army watching closely and the Grand Line ahead, he must decide how far he will twist the plot while sailing toward legend alongside the future King of the Pirates.
