Given how situational Nakime's Blood Demon Art is, it's easy to see why she has the weakest Blood Demon Art out of all known Twelve Kizuki. In fact, she wasn't even a member of the group and was just handed the title after the death of its former holder.
Mukagoji is officially the lowest member of the Twelve Kizuki, ranking as Lower Rank 6. While he also controls his own blood, much like Doma, his is a little less impressive. He can create an interesting blood mist, which hides his attacks from his opponent. Overall, Mukagoji doesn't make much of an impact on us.
The number engraved in their eyes represents how strong each Demon is. Upper Moon One is the strongest while Lower Moon Six is the weakest.
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.
Fortunately, Zenitsu was able to single handedly beat the Upper Moon 6. Not only did he defeat the demon, he also created a seventh form called the Flaming Thunder God. These are the demons who have been given the title of Upper Moon 6 in Demon Slayer.
Upper-Rank Five: Gyokko
As a fellow artist, Gyokko became distracted by Haganezuka's dedication to sword-polishing and opted to hold off on finishing off a wounded Muichiro. Tokito then manifested his Mark and effortlessly decapitated Gyokko with Mist-Breathing, Seventh Form: Obscuring Clouds.
8 Shinobu Kocho, The Insect Hashira
That being said, she's arguably the weakest Hashira when it comes to pure strength.
Tengen Uzui
This Breathing Technique gives him echolocation and other advanced hearing abilities. Even though he is large and muscular, and uses that to his advantage, his fighting style relies more on aesthetics and flashiness. He is the fastest Hashira, and the second physically strongest.
Kokushibo was the final Upper-Rank to die during Demon Slayer's "Infinity Castle" arc. Muichiro, Genya, Sanemi Shinazugawa and Gyomei Himejima fought together against Kokushibo, though Muichiro and Genya were no match for him and were killed.
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.
As such, the anime is now going to introduce a new character, Kaigaku, who will replace Daki and Gyutaro as the new Upper Moon 6.
Tanjuro Kamado a recurring flashback hero from Demon Slayer : Kimetsu No Yaiba. He was the husband of Kie Kamado, and the father of Tanjiro, Nezuko, Takeo, Hanako, Shigeru, and Rokuta.
He was soon decapitated by the combined force of Kanao and Inosuke, avenging Shinobu and her family. Trying to struggle for survival like Akaza, but lacking indomitable willpower as Akaza had, Doma's head slowly disintegrated and he met Shinobu's soul in the limbo, holding his severed head.
But, comparing the two characters in their best forms, Zenitsu might be just a tad bit faster owing to his Godspeed move.
1. Gyomei Himejima. Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
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.
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.
Killed And Was Killed By Doma
Before arriving at the Infinity Castle, the Insect Hashira consumed roughly 81 pounds of wisteria poison. Even though Doma killed her, he died just as quickly because of the sheer amount of poison he ingested after eating her.
1. Gyomei Himejima – The Stone Hashira.
The first of the Twelve Kizuki that was encountered in the series was the former Lower Rank Six, Kyogai, who is slain in battle by Tanjiro Kamado.
Akaza was also one of Muzan's favorite demons out of all his subordinates. The reason behind this is Akaza's extreme loyalty to his master. The Upper Rank Three demon was always sent away on special missions, something the Upper Rank 1 and 2 were often denied of.
