Some time in the last two years, Trafalgar Law learned about an important Poneglyph that was being guarded on Hachinosu. Showing interest in its contents, Law planned to infiltrate the island by hijacking the Rocky Port, a smuggling vessel belonging to an unspecified country that had shady dealings with the pirates of Hachinosu. At the time, the king and several nobles of said country were also riding on the Rocky Port, which sailed around under the guise of a simple passenger ship.[4]
Once the Rocky Port arrived on Hachinosu, a major battle between Law and the resident pirates ensued. This prompted two other parties to join the fight, MarinecaptainKoby and Blackbeard, with both having come to Hachinosu for their own separate reasons. Law, Koby and Blackbeard then started cooperating in an alliance of convenience, with Koby protecting innocent citizens during the incident[2][3] while Blackbeard defeated Ochoku, the then ruler of the island. Law also stole the hearts of 100 pirates present at the Rocky Port, later sending them to the World Government.[6]
Aftermath[]
After sending the 100 hearts to the Government as proof of his capabilities, Law was officially acknowledged as a Warlord of the Sea, as well as the incident's mastermind. Koby, for his actions of bravery, was labelled a hero and became widely-known.[2] At the same time, Ochoku was dethroned in his rule over Hachinosu, with control of the island being transferred to Blackbeard.[3] Their battle caused significant damage to the Rocky Port, with it only being fully repaired recently.[5]
It is unknown what happened to the king and noblemen of the country that was involved in dealings with Hachinosu, or the status and whereabouts of Ochoku.
↑One Piece Manga and Anime — Vol. 107Chapter 1081 (p. 17) and Episode 1115, Blackbeard mentions to Law that the pirates he stole the hearts from during the Rocky Port Incident were still prisoners on Hachinosu.
