One Piece : From Slave to Fleet Admiral Novel

During the Summit War, Koby publicly denounced the Marine Admiral's brutal methods before the world's eyes. Red Hair Shanks intervened to shield the principled soldier, but a blinding celestial spear materialized and killed him where he stood.

Admiral Jake, cloaked in his newfound authority, looked down at Koby's lifeless form with indifference.

"Annihilate the Whitebeard Pirates completely. Encircle the Red Hair crew. Execute anyone undermining our forces as a pirate sympathizer!"

In Wano Country, Jake confronted Momonosuke regarding the establishment of a Marine military installation. When the Kozuki heir refused, the family's name was erased from history the following morning.

"Once the maritime rail system unites every island across the seas, the legendary Golden Age of Pirates will finally come to an end."
