Demon Slayer: Every Nichirin Sword Explained

Demon Slayer Nichirin Swords

In the world of Demon Slayer, the Nichirin Sword is essential for the success of humanity in their battle against the demons. Although most resemble a common katana there are many variations of these nichirin swords and weapons that get used by numerous characters in the series. In this article, we will be going through every single Nichirin weapon used in Demon Slayer in detail.

What is a Nichirin Sword?

Nichirin Swords are special swords used and made specifically for the Demon Slayer Corps to slay demons. The swords are forged from a unique ore that constantly absorbs light which is the major weakness of all demons. Therefore, decapitation by the nichirin sword is one of the only ways that a human can kill a demon.

Nichirin swords take on a distinct color when it’s first drawn by its owner. This is the reason why they are referred to as color-changing swords. However, the owner is required to have a certain amount of skill or the blade will not change its color.

Genya’s Nichirin Sword

Genya’s sword is a standard katana and has no color because he can’t use any breaths so he’s not skilled enough for the nichirin blade to actually take a color. His handguard is pretty basic as well with just two hollow ovals that overlap its core and are a dull shade of brown.

Genya's Nichirin Sword

But that’s not his main weapon. He also carries with him a double-barreled shotgun that he uses for close and ranged combat that is loaded with nichirin bullets.  So with this shotgun that he carries around its bullets are made of the same material as the nichirin swords.

Gyomei’s Nichirin Sword

Gyomei uses a modified spiked flail and axe which is a swinging and whipping weapon with an axe chained to a spiked flail basically like a spiked ball.

The reason he uses this instead of a standard katana is because of his blindness. He uses the sound of the chain to appropriately and accurately direct his weapon to attack the enemy. 

Gyomei's Nichirin Sword

This, of course, is also made with the same metals as the nichirin blades and as far as handguards go he doesn’t have any.

The handguard is circular shaped with forced light indentations, a center of three eyes and several black veins and a golden border also added.

Kaigaku’s Nichirin Sword

Kaigaku’s sword is a flesh and demonic nichirin sword but still has the remnants of his human sword with the lightning pattern still visible and this is probably most likely due to his short time being a demon that his blade hasn’t fully transformed. Yet his handguard is incredibly similar to Zenitsu’s handguard but with a slightly darker core.
