The Demon Slayer Corps in 'Demon Slayer' uses Nichirin swords as their weapons of choice. These swords are crafted from Scarlet Crimson Iron Sand and Scarlet Ore, materials found exclusively in Sunlight Mountain on Mount Yoko. Because they constantly absorb sunlight, they offer one of the few permanent solutions to killing a demon. However, their effectiveness is limited to decapitation and is not as effective on other parts of the body.
Since these swords are crucial for killing demons, they are forged only for demon slayers who have passed the final selection. It is noteworthy that these swords take on a special color when they are drawn by their bearers for the first time.

Here are the 8 most powerful Nichirin swords in 'Demon Slayer.'
1. Tsugikuni Yoriichi's sword
Like Tanjiro, Yoriichi Tsugikuni, the most powerful demon slayer ever known, possessed one of the rarest sword colors. His Nichirin sword had an obsidian black hue, considered a bad omen in the demon slayer universe, indicating a short life. However, Yoriichi defied fate and lived to a ripe old age. Moreover, his sword blazed bright red during battle because he was a skilled user of sun-breathing techniques. Yoriichi's swordsmanship was so impressive that he was able to almost neutralize Muzan's regeneration abilities, striking terror into the demon's heart.
2. Kamado Tanjiro's sword
'Demon Slayer's protagonist, Tanjiro, wields an intriguing sword. Although he initially practiced water-breathing techniques, his first draw did not produce a blue sword. Instead, it was black, indicating proficiency in sun breathing. In the 'Demon Slayer' universe, black swords are less comprehensible and linked to misfortune and shorter lifespans.
3. Kokushibo’s sword
Kokushibo, the Upper-Rank One among the 12 Kizuki (Blood Moons), is a formidable foe in the 'Demon Slayer' franchise. His sword is one of the most distinctive in the series, capable of transforming at his discretion, resembling a tree-like weapon with branches extending from its sides. Although it was initially purple, indicative of his moon breathing techniques, he stained it with his blood, turning it red. He owned this sword before his transformation into a demon.
4. Himejima Gyomei's flail and axe
Gyomei Himejima, one of the Hashiras, wields a flail and axe, an unconventional weapon compared to the other swords crafted from the same material. However, it is undoubtedly one of the most potent weapons in the series, as even the Upper-Rank One among the 12 Kizuki, Kokushibo, could not shatter it.
The weapon's gray color represents Gyomei's Stone Breathing techniques. It is especially suited to his unique fighting style as a blind warrior, utilizing the weapon's echoes to perceive his surroundings.
5. Kanroji Mitsuri's sword
Mitsuri Kanroji, a Hashira member, wields a distinctive sword that resembles a whip, specifically a highly pliant and elongated katana. The weapon's form enables her to unleash swift and rapid attacks, as evidenced by her ability to keep pace with Upper Rank 4 Hantengu.
Her Nichirin Sword's pink hue reflects her love for breathing techniques. The sword's flexibility reflects her impressive agility in battle. Such a unique weapon is exclusively hers to wield, setting it apart from all others.
6. Tengen Uzui's cleavers
Tengen Uzui, a prominent figure in the Season 2 of 'Demon Slayer,' is a Hashira member who wields a unique pair of cleavers connected by a chain resembling nunchucks. Unlike traditional swords, these weapons are relatively heavy and sizeable. Nonetheless, Tengen wields them skillfully, delivering powerful blows.
The dual cleavers sport an amber hue, reflecting Tengen's sound breathing techniques. Legend has it that no demon has ever survived a single strike from his weapon, especially before his encounter with Upper Rank 6.
7. Muichiro Tokito’s sword
Muichiro Tokito is a young prodigy in the 'Demon Slayer' realm, having become a Hashira at the tender age of 14. He hails from a lineage of powerful demons, including Kokushibo. His weapon of choice is a seemingly ordinary katana, albeit with a unique white hue that corresponds to his mastery of the mist breathing style. Moreover, his Demon Slayer mark empowers the weapon to turn bright red. Muichiro's exceptional swordsmanship skills have garnered much recognition, earning the admiration of even Upper Rank One Kokushibo.
