Advertisement
From the fiery red Nichirin Sword to the intricate design of the Nichirin Whip-Katana, these weapons play a pivotal role in shaping battles. In this article, we’ll rank Demon Slayer’s Nichirin swords based on their power, symbolism, and impact on the series. So without further ado, let’s get started.
10. Nichirin's Twisted Sword of Obanai

Obanai Iguro is one of the few anime characters to possess dual eye color, which makes him stand out from the rest. In addition to his heterochromatic eyes, Obanai wields a heavily modified Nichirin katana that perfectly matches his Serpent Breathing style.
The sword consists of several twists and turns, reminiscent of his pet snake Kaburamaru. This particular blade was designed so that Obanai could draw his sword vertically instead of horizontally, making it effective in quick combat and surprise attacks.
9. Mitsuri's Nichirin Whip-Katana

A user of Love Breathing, Mitsuri Kanroji wields a very peculiar Nichirin sword that is extremely thin, flexible, and whip-like. The characteristics of her pink sword mirror her own abilities, which can be attributed to her superhuman flexibility, brute strength, and quick reflexes.
Using her katana-whip, Mitsuri's attack range is longer than that of the average swordsman, allowing her to perform attacks that bend and pierce through her targets. However, due to the unique shape of her sword, Mitsuri bends her katana multiple times to draw it correctly.
8. Zenitsu's Yellow Nichirin Sword

One of the most beloved and funniest characters in the series, Zenitsu Agatsuma wields a yellow Nichirin Blade that he uses to unleash his Lightning or Thunder Breathing style while confronting demons in their sleeping state.
Unlike most swords that have a single colored stripe, Zenitsu's sword is adorned with lightning bolts along the entire blade. The yellow sword combined with his breathing technique enhances Zenitsu's speed abilities, making him incapable of being caught by his enemies.
7. Red Nichirin Sword of Rengoku

The symbolic Red Nichirin has been passed down for ages by the Flame Hashiras with the previous known wielder being, Kyojuro Rengoku. Rengoku's fiery breathing style coats this sword in a red flame pattern, ensuring that demons are burned to death.
Being the heir to the Flame Breathing, he began his teachings under his father, but mastered the technique through careful study of the instruction books left behind by his ancestors. While Rengoku died at an early age, the strength of his sword was well demonstrated in the Mugen Train arc.
6. Giyu's Blue Nichirin Sword

Giyu is known in the anime community as the “King of Depression” for his reserved personality and serious but emotionless facial expressions. However, keeping his personality aside, Giyu is a very competent and skilled swordsman wielding a blue Nichirin katana.
Hailed as the most skilled water breathing user of his generation, Giyu's rapid mastery of his breathing technique allowed him to develop an entirely new form called "Dead Calm", which is considered one of the most powerful attacks in the series.
5. Sanemi Forest Green Nichirin Sword

The Green Nichirin Swords are connected to users of Wind Breathing, most notably the current Wind Hashira, Sanemi Shinazugawa. Sanemi's sword has irregular green-colored patterns engraved on both sides that complement his gritty and abrasive style.
Sanemi is among the strongest Demon Slayer characters and the second most powerful Hashira in the Demon Slayer Corps who was able to take on the Upper-Moon One with the help of this green Nichirin katana and this speaks volumes about his skills as a self-made swordsman.
4. Tengen's Dual Nichirin Cleavers

Befitting his flamboyant personality, Tengen Uzui carries an equally flamboyant array of weaponry. His battle weapon is not the normal Nichirin sword, but rather two gigantic double-edged cleavers that are held together at the hilt by a metal chain, resembling nunchucks.
Despite their weight and large size, Tengen is strong enough to control them well and strike hard with them. The weight of their blades allows them to generate immense explosive force, and it is said that no demon has survived a blow from Tengen's dual cleavers.
3. Tanjiro's Black Nichirin Sword

In the list of Nichirin swords Demon Slayer, Tanjiro's weapon is unique and interesting as it is associated with the Sun Breathing technique despite him originally being a Water Breathing user. Its blade is fairly standard with an obsidian black hue.
As Tanjiro has a notorious habit of damaging his swords during his encounters with demons, he has replaced his blade several times, the newest being the one he found inside Yoriichi Type Zero. However, black swords are not well understood and are seen as a stroke of bad luck for the wielder.
2. Kokushibo Meat Katana

Kokushibo is at the top of Muzan's demonic hierarchy, as he is the Upper-Moon One and a former Demon Slayer. His sword is one of the most unique in the series, being able to change according to his whims, as it is created from Kokushibo's own flesh and blood.
Before transforming into a demon, Kokushibo's sword was purple due to him being a Lunar Breath user, which turned blood red with veins and his eyes covering the blade. Kokushibo named his weapon Kyokokukamusari, which means "Hollow Cry of the Godless".
1. Yoriichi's Brilliant Red Nichirin Sword

The strongest Demon Slayer to ever exist, Yoriichi Tsugikuni, similar to Tanjiro, had one of the rarest sword colors in existence. Being the creator of the Breathing styles and user of the Sun Breath, Yoriichi's sword was a deep black, which would often turn bright red in battle.
Unlike the rest of the hunters, Yoriichi was born with the Demon Slayer mark. With the help of his sword, he was easily able to scare Muzan and nearly negate his regenerative powers in a one-sided duality, instilling fear in him.
