Nichirin Blades are special blades used by and made specifically for the Demon Slaying Corps to slay Demons. They are forged from a unique ore that constantly absorbs sunlight, one of the only major weaknesses of Demons. Therefore, decapitation by Nichirin Blade is one of the only ways a human can kill a Demon, the other being the use of a Wisteria-poison coated weapon.
Nichirin Blades take on a distinct color when first drawn by its owner, which is why they are also referred to as "The Color Changing Swords". However, the holder is required to have a certain amount of skill, or the blade will not change color.
Light pink blades are the blades of flower. The Breath of Flower fighting method is an updated Breath of Water style used by both Kanae Kocho and her sister Kanao Tsuyuri. There are seven forms of the Breath of Flowers style, culminating in a style that renders the rest of the world in slow motion.
