Nichirin swords, also known as Kimetsu No Yaiba swords, are remarkable weapons imbued with mystical properties. These Samurai blades featured in Kimetsu no Yaiba, are crafted from rare materials found in the highest mountain peaks and undergo a unique forging process. A distinctive aspect of their creation is that they must be exposed to sunlight for an entire year, allowing them to absorb solar energy, which endows them with their magical attributes and the ability to change colour.

White: Wielded by Muichiro Tokito, the Mist Pillar.
