What is the significance of Kikoku in Trafalgar Law's One Piece character arc?
Updated Feb 2026
Kikoku plays a specific and meaningful role in Trafalgar Law's character arc that goes beyond being a simple blade. Law received the Kikoku after becoming a Warlord of the Sea, and the sword has accompanied him through his most pivotal narrative moments: the Punk Hazard arc where he allied with Luffy, the Dressrosa arc where his plan against Doflamingo unfolds, and the Wano arc where his role in the alliance becomes critical. Law's specific fighting style - using Kikoku in conjunction with his Ope Ope no Mi room manipulation to control space and perform surgical strikes on opponents - creates an intimate connection between the sword and his devil fruit ability that is unusual among One Piece sword users. In this sense Kikoku is not just a weapon but an extension of Law's unique ability system. For collectors who are drawn to Law specifically as a character, the Kikoku is the physical object that best captures his identity as both a swordsman and a devil fruit user - the cross-shaped tsuba is a visual shorthand for all of this character complexity.
