Roger. Yet even though civilians largely disdain pirates, they secretly root for at least one of them.
A red‑haired girl from the Sabaody Archipelago is no exception: she admires Nami, the clever navigator of Monkey D. Luffy"s Straw Hat crew. Determined to send a letter of admiration to her idol, the Sabaody youngster is ready to defy the authorities who aim to stop Luffy and his companions from heading toward their next goal: the New World. But to achieve this, Nami"s devotee may have to endanger her life and disrupt the Marines" schemes, possibly sparking catastrophic fallout across the globe.
