Kikoku is a large version of the typical Japanese sword type known as nodachi. It has an oblong-shaped hilt trimmed with short white fur, a purple grip with two white rings around it and a yellow pommel, sheathed in a black scabbard decorated by white crosses from the opening to the bottom, and with a small piece of red rope tied near its opening.[2] The said rope often varies in length in several forms of media, though it has so far been its longest in One Piece: Pirate Warriors 2 and 3.
Due to its size, Law usually carries Kikoku over his shoulder (in contrast to other sword-wielding characters in the series, who either carry theirs on their hips or over their backs); yet in other times, he delegates one of his crewmates (namely Bepo) to carry it for him.[3]
Abilities
Law combines Kikoku with his Ope Ope no Mi powers, with the sword serving as a "scalpel" or an "injection needle" of sorts, using it to cut or pierce at a distance. At full power, Law can bisect an entire mountain[4] or meteor.[5] The sword could also block Doflamingo's strings, which is a notable feat as all weapons until then were easily cut by them (unless they were reinforced with Busoshoku Haki).[6]
Trivia
In the English localization of One Piece: Pirate Warriors 3, it is called Demon Howl in the term glossary gallery menu.
"Kikoku" is an archaic Japanese term for "the wailings of a restless ghost".
Law is rarely ever seen slashing with Kikoku directly. When he does use it offensively, a ROOM is often active, making the actual properties of the sword unknown, outside of the video games.
