What Is A Nichirin Sword – All You Need To Know

Demon Slayer is popular for its amazing animation and its jaw-dropping sword fighting sequences. The weapons used in this anime are specially forged swords called the “Nichirin Swords.”

There are a lot of intricate details about these demon slayer weapons that might not be obvious at first glance.

In this article, we will be discussing these Nichirin Swords and go over all the information about these demon-killing weapons. So without any further ado, let’s jump into the article!

What Are Nichirin Swords?


A Nichirin sword is a specially forged weapon which is capable of slaying demons. Any other normal weapon is not suitable for killing demons.

These weapons are made by skilled swordmakers for the members of the Demon Slayer Corps.

A nichirin sword is also called a “color-changing katana.” This is because, based on the skill and abilities of the user, it will change color when it is first weilded. Each of these colors has a different meaning, which we will cover later on in this article.

Even though this weapon is capable of killing demons, unless the user cuts off the head of the demon, it will not kill them. However, it is possible to make them severely bleed when used on other parts of the body.

Why Can the Nichirin Sword Kill Demons?

These swords are able to kill demons because of the special ore that is used to make them.

Demons have a weakness to sunlight and will perish when exposed to the sun’s energy.

The Nichirin sword ore is usually found in very high mountains, where it is soaked in the sun’s energy. Because of this, they kind of act like a portable sun that is sealed within the weapon.

There is no other weapon that can store up the sun’s energy like the Nichirin weapons. This is why these swords can kill demons.

How Are These Nichirin Swords Made?

A nichirin sword is forged with Scarlet Crimson Iron Sand and Scarlet Ore that are soaked in sunlight all year round.

Given the difficulty of making these swords, only those who belong to the Demon Slayer Corps are given these weapons.

After the final selection exams, the examinee will get the choice to select the ore for their future demon slaying weapon.

Then, the ore will be sent to the swordmakers from the secret swordsmith village. Here, the nichirin sword will be made with the chosen ore material and delivered to the Demon Slayer.

It is also a tradition where the swordsmith personally meets with the demon slayer and hands over the forged weapon.

Who Makes These Demon Slayer Swords?

There is a secret village for the people who make these swords. These sword makers live in the swordsmith village, which does not have that many people in it.

The entire village is basically a factory to produce nichirin swords, which are crucial for demon slayers.

This is why their village is kept secret from everyone. Therefore, those who visit the village are blindfolded to keep the location of the village hidden.
