The One Piece Kaku - DXF Figure from The Grandline Men captures the CP9 assassin in a poised, action-ready stance. Painted with crisp contrasts, the dark tailored suit features fine creases, lapels, and a slim tie, all reproduced with Bandai's signature paintwork. His calm expression sits beneath slender, neatly styled hair and glasses, giving him a composed, calculating look. The sculpt emphasizes Kaku's lithe silhouette, with subtle muscle definition and realistic fabric folds. The accessory weapons are integrated with precision, while the 170 mm height balances well with dynamic posing, allowing the figure to convey both elegance and danger in one compact display piece.

Kaku is a high-ranking member of CP9, an elite covert operations unit within the World Government. In the Enies Lobby arc, he demonstrates exceptional speed, precision, and swordsmanship, deploying Rokushiki techniques to outmaneuver opponents. He is part of the team that infiltrates the courthouse and battles against the Straw Hat Pirates and their allies. His calm, methodical nature contrasts with more flamboyant members of CP9, yet his loyalty to the organization is evident in every encounter. The character's backstory blends duty with moments of personal resolve during the mission to capture Nico Robin. The figure's design reflects this dual nature: a composed operative ready to step into battle, yet still recognizable as a stylish, disciplined fighter.
