One Piece: The Observation Haki Compass Awakens

"What if Luffy and his crew discovered that the 'Observation Haki Compass' watching them from afar was actually a transmigrator?!"

Modern programmer Lin Xiaoman unexpectedly obtains the "Pirate God" System, but a mistake binds him to the "Observation Haki Compass," forcing him to follow the Straw Hat Pirates' adventures as a bystander.

He only wants to quietly observe and take notes, but a System bug forces him to complete the "Collect the Shichibukai Badges" quest. He even has to team up with old foes like Crocodile and Aokiji?!

When Robin discovers that he can foresee danger, Franky steals the compass and turns it into a mechanical arm, and even Luffy starts calling him "the mysterious navigator"...

"System alert: You have triggered the hidden ending: become the first 'Unsung Hero' in pirate history!"

(System-driven story + sweet romance + subverting expectations, with plenty of laughs and a passionate underdog comeback.)
