Kaku
Kaku is a One Piece villain known for mastering all Rokushiki techniques and the Giraffe Giraffe Fruit in the water-7 arc.
Biography & Character Analysis
Kaku is one of CP9's most talented agents, a master of all six Rokushiki techniques who initially infiltrates the Galley-La Company as a seemingly harmless shipwright. His cover as an honest worker contrasts sharply with his true nature as a cold, calculating assassin trained by the government. Kaku's mastery of Rokushiki—the Marine's legendary combat techniques—surpasses even most veteran agents, making him one of the organization's most valuable operatives.
During the Water 7 incident, Kaku's consumption of the Giraffe Giraffe Fruit transforms him into a long-necked hybrid with extended reach and devastating strength. His combination of Rokushiki mastery and Devil Fruit power made him a formidable opponent for the Straw Hats. Though defeated by Zoro during Enies Lobby, Kaku survives and continues working for CP9, eventually appearing in later arcs, suggesting his career in government service continues despite his initial failure against the pirates.

Powers and Abilities
