### Summary
A painful flashback reveals the origins of Koala, a future member of the Revolutionary Army, who endured years of brutal slavery under the World Nobles. Her freedom came only through the heroic intervention of Fisher Tiger, the fish-man adventurer who attacked the holy land of Mariejois to liberate slaves of all races. This act of defiance not only saved Koala and a young Boa Hancock but also forged the Sun Pirates, a crew of freed slaves including Jinbe and Arlong. However, the deep scars of oppression festered differently in each survivor, shaping Arlong's fanatical hatred for humans—a cycle of violence that now threatens to consume Fish-Man Island.
