Zephyr's Son: The Marine Who Doesn't Know One Piece

Waking up in a world of pirates and 'justice' gone mad was shock enough. But for Hailan, son of Marine legend Zephyr, the true nightmare was not knowing this was the infamous One Piece world – a world where his family was brutally murdered, and he inherited a past he barely understood. Thankfully, a mysterious System awakened. 'Perception' honed his senses to superhuman levels with every Rokushiki mastered. 'Calculation' allowed him to unravel any mystery, any strategy, simply by gaining others' 'identification.' His path to power wasn't through pre-knowledge, but pure, calculated ascent. Now, an intern Marine, Hailan navigates treacherous seas, outwitting hardened pirates and cynical superiors. But as he unravels the dark truths behind the World Government's twisted 'justice,' he must decide: uphold a flawed system, or burn it all down for a justice truly his own?
