Read Kogane

Kogane Read, also known as the Walking Fortress (insert japanese here), is a well known pirate and an even more well known thorn in the side of the world government. She controls Steelworks Island, a man made island situated at the center of Gotthard Tunnel, a tunnel she personally excavated through the Red Line. Despite immense interest in her work, and depriving the world government of a massive amount of revenue, she has managed to hold her own against all comers, securing her position as one of the most influential people in the world.

While Kogane is probably capable of using Kenboshuko Haki, she has completely neglected it in favor of specializing exclusively in Busoshoku Haki.

Busoshuko Haki
Busoshuko Haki, an art well known to most of the stronger combatants of the world. Knowledge of this is necessary to thrive in the era of the Devil fruit.
