A young man from modern-day Earth transmigrates into the world of One Piece and awakens a System, but the System has a glitch in its understanding of reality.
Cognitive mismatch: The System forcibly interprets things in the pirate world through the lens of cultivation (pirates = rogue cultivators, Sea Kings = demon beasts or magical pets, Marine Base = sect, Berries = spirit stones, Devil Fruits = demonic treasures or demon cores).
The Marines' style goes completely off the rails: Garp gladly accepts the title of "Ancestor," while Sengoku calls himself "Sect Master."
The absurd gap between missions and reality: "Exterminate the rogue cultivators 400 nautical miles away" means wipe out the Black Bear Pirates; "Tame a magical pet" means tame the Lord of the Coast, who ends up as the protagonist's "sect-protecting divine beast" and is often fed "demon beast meat," which is actually chunks of Sea King meat; "Sect tournament" means a Marine internal martial arts competition or the World Military Draft exam.
The rewards don't match their names: The rewards sound grand, like "Foundation-Building Pill" and "Marrow-Cleansing Fluid," but in practice they're potent body-strengthening or healing medicines, or simply ordinary but useful items from the pirate world.
Subtitle: From "Sect Steward" to "Ancestor Garp," the Marines' style is getting more and more bizarre!
