During the fight, Nezuko realized that they were no match for the Upper Moon 4 Demon. Hence, she used her Blood Demon Art and infused it with Tanjro's Nichirin Sword, turning it bright red as it started burning. This unlocked the true potential of the sword, allowing Tanjiro to behead Urogi, Karaku, and Sekido!
When Tanjiro first got his Nichirin Sword on Demon Slayer, and it changed color to match the personality of its user like all Nichirin weapons do, many fans were surprised that Tanjiro's katana turned black.
Bright Red Nichirin Sword ( 赫 かく 刀 とう , Kakutō?, ViZ. "Bright Red Blade") refers to the ability that turns a Nichirin Sword bright red with special properties for a certain amount of time and is only accessible by Demon Slayers who have awakened the Demon Slayer Mark.
The unusual color is still an indication of Tanjiro's talent though because Nichirin blades do not change color for a wielder who is unskilled with a sword. Tanjiro pushed himself beyond his body's limits for two years while training to become a Demon Slayer, as he is not naturally gifted.
Black. Toho Co., Ltd. Black is the most mysterious color of all the blades, and is held by the main character, Tanjiro. It is a rare blade and represents the sun; it also holds a theory that the demon slayers who own this sword are not to live a long life.
Tanjiro Kamado wields a black Nichirin blade, but the symbolism of such a sword was initially unknown. Black blades are seen as a rarity, as demon slayers who wield them are doomed to die young. No wielder of a black sword has ever become a Hashira, either. However, this is all superstition.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
Tengen Uzui
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness. But he is also ultimately kind and caring, with great love for his three wives as well as the other Hashira.
Zenitsu Uses a Special Katana Called a Nichirin Blade
These Nichirin swords are made from Scarlet Crimson Iron Sand and Scarlet Ore which absorbs sunlight, making it possible to kill demons.
That life threatening condition altered him and afterwards, it develops into a flame-like pattern and is his new Demon Slayer Mark. It remains that way and continues when he uses his abilities. This is a cool piece of mythos that will evolve as the story continues.
Demon Slayer: Kimetsu no Yaiba Swordsmith Village Arc episode #2 sees Tanjiro discover the "secret weapon" hidden in the Swordsmith Village; a battle training doll called Yoriichi Type Zero.
9 Water Breathing: Ninth Form – Splashing Water Flow Turbulent. This form was first used in Tanjiro's battle against Kyogai, the former Lower Moon Six of the Twelve Kizuki, a group of demons known to be the strongest of their kind.
During episode three, we learned that the Yoriichi Type Zero was built by Kontetsu's ancestors more than 300 years ago during the Sengoku era.
Tanjiro certainly did a lot of good with his Water Breathing techniques, but his ability to use Sun Breathing both gives him an edge in battle and allows him to stand out among the incredibly powerful Hashira he fights alongside.
Yup Demon Tanjiro is immune to Nichirin Blades.
But, comparing the two characters in their best forms, Zenitsu might be just a tad bit faster owing to his Godspeed move.
Shinobu Kocho Is the Weakest Hashira
The Insect Hashira, Shinobu's petite frame prevents her from being physically able to decapitate any demon, be it an Upper-Rank or the weakest demon in Japan. At one point or another in the manga, all nine Hashira in Demon Slayer encountered an Upper-Rank.

He was a genius when it came to swordsmanship and nearly killed Kibutsuji Muzan all by himself. So now, Tanjiro, the protagonist of the Demon Slayer series, has access to a sword that belonged to the best swordsman to have ever lived.
Yoriichi Tsugikuni is a Demon Slayer from 300 years ago, and the inspiration for Kotetsu's training doll.
Tanjiro's ancestor was a good friend of Yoriichi and arguably was one of his only true friends. Therefore Yoriichi gave the earrings as a gift, and since then they have been passed down the generations until they reached Tanjiro.
8) Muzan hates being called pale or dead
Muzan is the most powerful demon in the entire series, and is responsible for creating all demons. For someone who considers himself to be perfect, it is natural that he will hate being called pale or dead. This is established quite early on.
why tanjiro's head is so hard? Well, it's thanks to his genetics, as his mother, Ki Kamado, passed down the trait of a rock hard head to him. In fact, Nezuko heard a story about their mother. scaring away a boar by headbutting it, which shows that Ki was also very tough and fearless.
