Giyu was the first Hashira to be introduced in the series, making his debut in the very first episode.
1 Gyomei Himejima, The Stone Hashira.
Well as far as I know, Giyuu, Kanae,Tengen and Gyomei were hashira by the time Sanemi was promoted. Shinobu became a pillar before Rengoku when the latter wanted to replace his father.
He became a Hashira after just two months of training, a feat achieved only by Gyomei Himejima.
He is a Demon Slayer of the Demon Slayer Corps and the current Mist Hashira ( 霞 かすみ 柱 ばしら , Kasumi Bashira?). Muichiro, along with his brother Yuichiro Tokito, is also a descendant of Upper Rank One, Kokushibo.
and Tengun for 6. However, the longest sitting member of this group is Gyomei, who has been a Hashira for 8 years.
Demon Slayer's Tengen Uzui is considered to be one of the weakest Hashira due to almost losing this fight, but the fact is that Tengen only looks weak when compared to the most overpowered Hashira.
The eccentric and flamboyant Tengen Uzui is the current Sound Hashira. This Breathing Technique gives him echolocation and other advanced hearing abilities.
Yukire Hanazawa ( 花沢 はなざわ 雪 ゆき れ, Hanazawa Yukire?) is a Demon Slayer and the Ice Hashira ( 氷 こおり 柱 ばしら , Kōri Bashira?) of the Demon Slayer Corps.
When it comes to pure strength, Shinobu Kocho is the weakest Hashira in Demon Slayer. She doesn't even have enough strength to decapitate a demon's head and she makes up for it by injecting poison into the demons.
Unfortunately, he retired at the age of 35, when he lost his right leg in a fight with a demon. Since then, he devoted his time to teaching the next generation of demon slayers, most notably, Zenitsu Agatsuma, who lovingly called him "grandpa".
Unfortunately, the answer to this question would be, no, he did not. Zenitsu, along with Tanjiro and Inosuke got way stronger than average corps members with training. In fact, he became one of the very few to even invent a new form of Thunder Breathing. However, his dream of becoming a Hashira was never realized.
2) Rengoku
However, Rengoku was forced to face off against Akaza who was Upper Moon 3. The Flame Hashira carried out his duties until his death as he did not let his comrades get injured.
Nezuko setting Tengen on fire. By the end of the battle, Gyutaro's poison has spread throughout Tengen's body resulting in his inability to speak. As he lays dying from the poison, Nezuko Kamado intervenes and uses her her Blood Demon Art to burn the poison out of his system, allowing him to rejoice with his wives.
Rengoku's fight in the Mugen Train arc showed his incredible speed and reflexes. He was able to match Akaza's speed, and his movements were so fast that it was almost impossible for the naked eye to keep up. Tengen, meanwhile, is the fastest runner out of all the Hashira.
1) Shinobu Kocho
The Insect Pillar of Demon Slayer Corps, Shinobu is undeniably the smartest individual.
Rengoku's Unwavering Will Was His Greatest Weakness
Since he believes it is his responsibility as someone strong to protect those weaker than him, he will make sure he does just that. Rengoku sees any mission through to the very end, even at the cost of his life.
5 Hashiras who die in Demon Slayer, and how it happens.
1 Muzan Kibutsuji
The Demon King Muzan Kibutsuji has seven hearts and five brains, making him one of the most intelligent characters in the Demon Slayer anime series.
Introduced in Demon Slayer season 3, Muichiro Tokito is arguably the youngest in the Demon Slayer Corps.
