The Endless Sword Technique begins as a resonant Ruler technique that weaponizes all nearby sharp edges through sword aura, creating a symphony of simultaneous strikes. By the Underlord stage, it evolves into a more refined, invisible cutting force that transcends physical blades entirely. This progression mirrors the wielder's advancement from manipulating existing sword aura to commanding pure cutting intent.
