The Zanmato (also known as Demon Edge in the SNES/PS version) is Crono's tenth-level katana in Chrono Trigger. It has an attack power of 90 and does 1.5x damage to magical beings. It can be bought in Algetty for 17000G. It can also be bought in Medina Village for 65000G, although the player is unlikely to be able to afford it without grinding at that point in the game.
The In-battle sprite is colored with a unique light-violet/lavender hue, while its slashing trail is the same as both the Primeval and Yaksha Blades (a double spark forming a lighting bolt effect), only colored white-violet in its image.
