In the era of great pirates, the Navy held high the flag of justice on the surface, but secretly there was an unknown department called the "Shadow Force." They are ghost agents who do not exist in any files. Their mission is to sneak into the darkest corners of the pirate world and perform shady tasks. Arthur Phoenix is one of the most special. When he was only twelve years old, he lost all his relatives in a devastating pirate attack and was rescued by the naval hero Garp and taken to a secret base. As a mirror fruit user, he can perfectly copy anyone's appearance, voice and even combat abilities. He is the navy's sharpest hidden weapon. His first mission was to sneak into the Shichibukai - approaching Crocodile under a false identity. But in Alabasta, he met a boy wearing a straw hat. Luffy. That guy who desperately pursued freedom made Arthur question the "justice" he had always been loyal to. As he shuttles and lurks among more dangerous forces such as CP9 and the Four Emperors, a shocking mystery about the ancient kingdom, a hundred years of blankness and the true origin of the mirror fruit gradually emerges. And he discovered that his life had been a carefully designed game from the beginning - he was not only the shadow of the navy, but also a tool for the world government to cover up the biggest secret. When the final showdown comes, Arthur must make a choice: continue to be a competent shadow, or break the mirror and become his true self.
