Demon Slayer Nichirin Sword Colours and Meanings

Demon Slayer: Kimetsu no Yaiba is almost entirely an action-oriented anime. As such, weapons have a huge role in setting the fighting sequences.

Kimetsu no Yaiba has introduced us to weapons ranging from swords to even strange weapons such as balls.

But we’re here to address the uniform weapon of the Demon Slayer Corps — swords, known as ‘Nichirin Blades’ or “Colour Changing Swords.”

1. Quick Answer

Nichirin swords are special swords used by and made specifically for the Demon Slayer Corps to slay Demons. They are forged from a unique ore that constantly absorbs sunlight, which is one of the only major weaknesses of demons.

One of the only ways for humans to slay Demons is by using these Nichirin Swords.

A rare identifying factor of these swords is its color. They take on a distinct color when first drawn by its owner. The colors represent some traits of its user. Hence, these blades are also referred to as “The Colour Changing Swords”.

2. Nichirin Blades

Nichirin Blades are made with materials acquired from Mt Yoko, a mountain that receives the maximum amount of sunlight.

The Scarlet Crimson Sand and Ore creates steel capable of absorbing sunlight. This steel is modeled into a sword that is customized in terms of shape and functionality to fit its user best.

Decapacitation of a demon with these blades is enough to provide them with eternal sleep. When the user of the blade takes it up from the swordsmith, the color changes, imbuing the blade with different colors and properties.

These colors are tied with certain breath styles and influenced by its users. This aspect of the swords embodies the thought that the sword is a representation of its user and their background. Thus, the personality, talent, technique, and the bond of the user with its sword defines it.

3. The Colours and its Symbolism

I. White

The first sword color on this list is the white blade, which symbolizes mist. The demon slayer who wields a white Nichirin Blade is the Hashira, Muichiro Tokito, the Mist Pillar of the Demon Slayer Corps. The Breath of Mist style is derived from the Breath of Wind.

Muichiro’s temperament is calm, and he’s often seen lost in his thoughts. The essence of his absent-mindedness and eccentric personality is aptly represented through the color white.

II. Grey

The grey Nichirin Blade symbolizes stone. The Stone Pillar of the Demon Slayer Corps, Gyomei Himejima, wields a grey blade. The symbol of the stone nicely reflects Gyomei’s personality, both strong and sturdy.

The color grey usually symbolizes stability and wisdom, which are two inherent qualities that Gyomei possesses. Just like a stone, he is strong and grounded.

Unlike the traditional Nichirin Blade, Gyomei uses a hand-ax that has a spiked flail attached to the hilt through a long chain. His weapon was also forged using a superior technique than that of the Nichirin Blade, but it is forged with the same unique ore.

III. Yellow

The yellow Nichirin Blade, one of which belongs to Zenitsu Agatsuma, symbolizes thunder. Zenitsu Agatsuma is a practitioner of the Breath of the Thunder derived from Breath of the Sun and wields a yellow blade. Absent from where the action takes place, Zenitsu’s powers arise when the situation demands it.

Zenitsu’s courage is as sudden and explosive as his powers. The most interesting aspect of his blade is that while most Nichirin Blades take on colors as a solid band running down the length of the blade, the coloration on Zenitsu’s blade is unique in that it instead forms a lightning bolt motif down the length of the blade — hinting at the unique properties a blade can possess.

IV. Indigo-Grey

The Indigo-grey color of the blade symbolizes beast. Inosuke Hashibara, who practices the Breath of the Beast derived from Breath of the Wind, wields such a blade. Inosuke wields two chipped blades of Indigo-grey to slay demons.

The Breath of the Beast was developed by him while living his life in the mountains and embodies the animalistic nature of his personality — short temper, lack manners, pride, and the inherent need to fight against the strong.

V. Pink

The pink Nichirin Blade symbolizes love and belongs to the Breath of Love style. This blade color is used by Mitsuri Kanroji, one of the Hashira. She’s an emotional and passionate person who can also be quite shy and bubbly.

During the battle, she is courageous and can face the strangest Demons with confidence. Therefore, a pink blade for her is the most suitable.

VI. Light Pink

A light pink blade symbolizes flowers. It is wielded by both Kanae Kocho and her sister Kanao Tsuyurii. Her style is usually dependent on speed and her reflexes, allowing very little presence in battle.

There are seven forms of the Breath of Flowers style, culminating in a style that renders the rest of the world in slow motion.

VII. Green

A green blade is wielded by Sanemi Sanegazawa, who practices the Breath of the Wind. It symbolizes the wind. Like the wrath of strong winds, Sanemi can bring down demons due to his hatred towards them.

The green Nichirin Blade symbolizes wind and is wielded by Sanemi Shinazugawa of the Demon Slayer Corps. Just like the wrath of strong winds, Sanemi brings down the Demons due to his burning hatred towards them.

Sanemi is just as boisterous and cyclonic as the breath style he’s mastered, unleashing tornadoes of sword slashes on the demons unlucky enough to face him.


Kyojuro Rengoku of the Breath of Flames wields a red blade. It symbolizes flame. His charismatic and energy-driven personality is quite aptly captured by the color red.

Kyojuro can bring raging flames down on his worst enemies. Just like Zenitsu, his blade takes the form of a flame motif down the length of his blade.

IX. Blue

The blue blade symbolizes water. Giyu Tomioka, the Pillar of Water in the Demon Slayer Corps, wields this blade that he uses with his Breath of Water style, making him one of the most formidable among the Pillars.

Giyu’s fighting style is quite fluid and calm, just like water. His logical personality is linked to his Breath Style, and therefore, blue is the perfect color for his blade.

X. Black

The main character, Tanjiro Kamado, wields a black Nichirin Blade, but the symbolism of the black blade is unknown. This is because black blades are seen as a rarity, as demon slayers who wield them don’t have a tendency to live long.

Tanjiro uses the Breath of the Water and Dance of the Fire God. Theories are circulating that the black symbolizes charcoal as Tanjiro’s past job was to sell charcoal.

Others believe it symbolizes the Sun, which would explain the rarity of it as Breath of the Sun Style is the oldest and an almost extinct style. Interestingly, black is the color that absorbs the most sunlight — a major weakness of demons.
