Blade Change

Nichirin Blade is the name for the swords used by the Demon Killing Corps. Due to changing color depending on who their owner is, they are also known as The Blade of Color Change.[1]


Forging ProcessEdit

Nichirin Blades are forged with Scarlet Crimson Iron Sand and Scarlet Crimson Ore, both of which are found on the Sunlight Mountain, which is perpetually bathed in sunlight all throughout the year.[2]
