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 begin.
10. Nichirin's Twisted Sword of Obanai

Obanai Iguro is one of the few anime characters to possess dual eye color, which sets him apart 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 features several twists and turns, reminiscent of his pet snake, Kaburamaru. This particular blade was designed so that Obanai could draw his sword vertically rather than horizontally, making it effective in fast-paced combat and surprise attacks.
9. Mitsuri's Nichirin Whip-Katana

A user of Love Breathing, Mitsuri Kanroji wields a unique 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 lightning-fast 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 her sword's unique shape, 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, which have a single colored stripe, Zenitsu's sword is adorned with lightning bolts running the length of the blade. The yellow sword, combined with his breathing technique, enhances Zenitsu's speed, making him impossible for his enemies to catch.
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 with a red flame pattern, ensuring that demons are burned to death.
As the heir to the Flame Breathing, he began his teachings with his father but mastered the technique through careful study of the instruction books left behind by his ancestors. While Rengoku died early, the power 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, yet emotionless facial expressions. However, 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 associated with Wind Breathing users, most notably the current Wind Hashira, Sanemi Shinazugawa. Sanemi's sword has irregular green patterns engraved on both sides, complementing his bold 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 face 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 standard Nichirin sword, but rather two gigantic double-edged cleavers 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 of the Demon SlayerTanjiro's weapon is unique and interesting, as it is associated with the Sun Breathing technique, despite his original use of Water Breathing. Its blade is fairly standard with an obsidian black hue.
Because 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 Beef Katana

Kokushibo stands at the top of Muzan's demonic hierarchy, being the Upper-Moon One and a former Demon Slayer. His sword is one of the most unique in the series, capable of changing at 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 his use of Lunar Breath, 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 Bright Red Nichirin Sword

The strongest Demon Slayer who ever lived, Yoriichi Tsugikuni, similar to Tanjiro, had one of the rarest sword colors in existence. As the creator of the Breathing Styles and a user of Sun Breathing, Yoriichi's sword was a deep black, often turning bright red in battle.
Unlike the other hunters, Yoriichi was born with the Demon Slayer mark. With the help of his sword, he was easily able to frighten Muzan and nearly negate his regenerative powers in a one-sided duality, instilling fear in him.
