The Wind Hashira has one of the saddest backstories in Demon Slayer. His mother had turned into a demon and had killed five of his siblings. He was forced to kill his own mother in an attempt to save his only remaining brother, Genya.
Shinobu Kocho is a capable Demon Slayer whose worthy of being the Insect Hashira. That being said, she's arguably the weakest Hashira when it comes to pure strength. However, brawn is not the only way to determine power in Demon Slayer.
We first see Doma when he is still the Upper Moon Six while he is in the middle of eating a geisha. Later he becomes even stronger and rises to the position of Upper Moon Two. He dies because of the lethal amount of poison he absorbed through Shinobu Kocho's body followed by Kanao Tsuyuri beheading him.
Gyōmei Himejima (悲鳴嶼 行冥, Himejima Gyōmei) is a supporting character in the 2016-2020 fantasy dark manga series Demon Slayer: Kimetsu no Yaiba. He is the Stone Hashira of the Demon Slayer Corps. He is voiced by Tomokazu Sugita (Japanese) and Crispin Freeman (English).
It is later revealed in an extra chapter that he cries extremely easily at almost anything, even crying for something as minor as when the garbage is messy. He was taught by a fellow monk. Gyomei loves cats, a trait he has in common with the Love Hashira, Mitsuri Kanroji.
In a nutshell, Muzan, being the progenitor of demons, is not scared of Doma. However, he is irritated by his inability to decipher Doma's thoughts and feelings, which is the ultimate control he has over all of his creations. Upper-Rank Two: Doma is a nihilistic maniac and a misanthropic cold-blooded demon.
Gyomei is extremely emotional and caring and is always concerned for those around him. This could be the main reason why he is always crying in the Demon Slayer series.
No one killed Sanemi Shinazugawa. Sanemi almost died when he tackled his sister Genya from a window in order to protect her from a demon attack, but was saved by his friend Masachika who healed his wounds.
Muzan was responsible for killing many humans and Mitsuri was one of them.
Tanjiro decapitates Akaza with the Hinokami Kagura: Setting Sun Transformation. Akaza was bewildered, wondering how Tanjiro did not have any fighting spirit, comparing this feeling to fighting against a plant. He acknowledges that Tanjiro surpassed his speed.
But there is one who is the friendliest of them all, and that is Kiyogiro Rangoku, the Flame Hashira. Among the pillars, there is not a single negative thing revolving Rangoku. Such an honest guy, and his character influences others positively. In Demon Slayer, Liu and Rangoku are not shown to have any interactions.
This feeling of survivor's guilt strikes again when he believes Tanjiro has died after the fight against Muzan. Giyu, while he sheds tears, admits how he is always the one who is saved. Despite his stoic nature, Giyu is shown to be protective and caring towards those he is close to and considers his friends.
When Giyu later hears about Shinobu's death, he suddenly recalls her smiling face while being visibly shocked and upset by the news.
One fateful day, Kanae was attacked by a demon, which turned out to be Upper Rank 2 Doma. He did not have time to eat her, and left her fatally wounded and her injuries took her life as the sun rose. This left a big shadow on Shinobu and Kanao, even today.
Tomioka Giyu = killed by Tanjiro Kamado. Tanjiro Kamado = killed by Nezuko kamado ( or another demon ) ; or executed for killing a hashira and have protected a demon. Nezuko Kamado = burned to sunlight , killed by a hashira , or eaten by Muzan Kibutsuji ( if she conquires the sun )
While there were numerous remarkable moments in episode 9, one scene, in particular, captured the collective attention of fans worldwide, the beheading of Gyokko.
