At the end of the day, none of the Hashira could've defeated Akaza – even though a few of them could've succeeded in decapitating him. Akaza proved himself to be too strong to be dragged into sunlight, meaning there'd be no way for any of the Hashira to kill him.
Muichiro can defeat Akaza easily with his petite body that leverages his speed. Moreover, his ability of Transparent World can aid him in landing a fatal blow on Akaza's weak spot.
However, when Keizo and Koyuki eventually got killed, Akaza went berserk and ended up killing more than 60 people just with his bare hands.
Gyomei is truly the only Hashira that is even close to killing Akaza.
No. The Uppermoon Demons Cannot Be Kill Solo You Must Be Atlist 3–4 Demon Slayer If Not You Will Be Killed. Doma And Akaza Should Not Be Underestimated Cause These 3 Uppermoons Kokushibo,Doma,Akaza Should Not Be Underestimated. Well Yoriichi Is The Only Hashira That Can Kill This 2 Easily.
7 Strength: Tengen
Rengoku was an elite fighter with immense strength. He was able to fight Akaza, who was a member of the Upper-Rank Three. Even after sustaining serious injuries, Rengoku still had enough power to hold down Akaza, and was able to send Akaza fling into the forest with a single slash.
In conclusion, Nezuko cannot beat Akaza in Demon Slayer. In terms of power, physical abilities, regeneration rate and overall combat ability, Akaza is far superior compared to Nezuko.
After awakening his demon slayer mark, Giyu greatly overpowers Akaza. However, he is able to keep up with the fight only because of Tanjiro. If Giyu had soloed against Akaza, he would have died.
Yoriichi Tsugikuni was the first Demon Slayer and also the one who invented Breathing Techniques in the first place. Yoriichi was born with the Demon Slayer mark and prowess in swordsmanship. His powers were beyond comparison as he defeated Muzan once and had him on the verge of death until he managed to escape.
Despite being a blood-thristy demon who has murdered several people, he has a set of principles he adheres to. One thing that Demon Slayer fans have noticed is that Akaza refuses to eat or kill women. Additionally, the Demon King, Muzan, gave Akaza special permission to do so.
Akaza. Because of his desire to become stronger and Doma's strength allowing him to surpass himself to become Upper Two, Akaza harboured an intense hatred of Doma.
Gyomei is currently the strongest Hashira.
Zenitsu is clearly on the same level as Hashira. If we compare him to Shinobu, his speed is far better, while she lacks quite a lot in raw power. There is a good chance that he could beat Shinobu if the two decide to fight.
Since Tanjiro accessed the See Through World and achieved the Selfless State, he was shown to have effortlessly decapitated Akaza.
13th form Tanjiro simply blitzes Akaza. In that form, he's relative to WH Muzan in speed who is faster than all the UMs.
Tengen Uzui
He is the fastest Hashira, and the second physically strongest.
1) Gyomei Himejima
He, along with Sanemi Shinazugawa were able to beat the Upper Moon 1, Kokushibo. The demon was in awe of Gyomei's physique and declared him to be the strongest Demon Slayer he had faced in 300 years.
The last member, Upper Moon Four Nakime, ends up being killed by Muzan Kibutsuji himself to stop the Dimensional Infinity Fortress from being controlled by his enemies.
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.
Shinobu Kocho Is the Weakest Hashira
Of the three Hashira who were killed by Upper-Ranks -- Rengoku, Shinobu and Tokito -- Shinobu was the only one who was killed almost instantly when she encountered Doma, Upper-Rank Two.
1) Gyomei. Gyomei Himejima is the strongest Hashira in Demon Slayer. This fact has been established in the manga as Tanjiro, Inosuke and Zenitsu all agree that he is the strongest member of the Demon Slayer Corps.
That means Rengoku can run at least 256 km/h! As such, Rengoku runs with “total concentration” at a 256 km/h speed… That's as fast as a bullet train!! Meanwhile, the Speed Demon is estimated to have a speed of 100 km/h, about the same as the steam locomotive used at the time, shown in the animation.
