History

Rock's Arrival

Shakuyaku traveled to Hachinosu after retiring from the Kuja Pirates, intending to live on the island despite its status as Rocks Pirates territory. Rock accompanied her after forcing the Kuja Pirates to give him a ride. 8 9 10

Upon reaching the harbor, Rock openly called Hachinosu disgusting and spread his Observation Haki across the island. His presence was noticed by Whitebeard, Charlotte Linlin, Shiki, and Rocks D. Zebek; Rock and Rocks then locked gazes across several kilometers. 10

Harbor Battle

Rock incapacitated nearly every pirate surrounding him with a massive lightning strike, while deliberately leaving Shakuyaku’s area untouched. 11 He then defeated Kaido in a single attack before fighting Shiki throughout the harbor and sky. 11 12

Rock’s battle with Shiki caused catastrophic damage to Hachinosu’s harbor, buildings, sea, and skies. His Thunder Roar · Heavenfall Prison immobilized Shiki and disrupted the Float-Float Fruit through electromagnetic pressure; Rocks intervened before the finishing attack could kill Shiki. The remaining lightning cracked the coastline and sent enormous waves into the sea. 12 13

Afterward, Rocks invited Rock to join the Rocks Pirates. Rock refused, declaring his intention to join the Marines instead, then clashed directly with Rocks. Their collision vaporized seawater, melted parts of the island, and caused Hachinosu to begin sinking before Rock escaped in lightning form. 14

Shakuyaku's Extortion Bar

Shakuyaku later established the Extortion Bar in central Hachinosu. Her reputation gave the establishment unusual authority: pirates lined up obediently, avoided making trouble, and accepted exorbitant prices and poor service. 36

The bar became a rare neutral space where even Rocks and Roger avoided fighting. Shakuyaku’s rule forbade private fights within the establishment, forcing hostile visitors to take conflicts out to sea. 37 38
