8 Shinobu Kocho, 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.
Muichiro is a 14-year-old boy at the time of his death and had a youthful appearance befitting said demographic. His pale turquoise eyes are large and empty-looking and his complexion is very light. He is fairly short and had a delicate figure which led Tanjiro to believe he is physically weak.
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. His strength was showcased during the fight against Kokushibo.
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.
If Sanemi had been the one to encounter Akaza, while he surely would've given a better fight than Rengoku did, Sanemi probably wouldn't have emerged victorious regardless of Akaza's handy Compass Needle that makes him nearly impossible to decapitate anyway.
people also like to say tengen is weak because he had trouble with "upper moon 6" gyutaro was stated to be stronger than what his place would seem because daki holds him back.
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. Such a weapon takes immense precision and soundness to use without inflicting personal damage.
Mitsuri Kanroji is a 19-year-old young woman with bright green eyes, with long eyelashes and a small mole. She has long pink hair mixed with neon-green paint, wearing three thick braids and five shorter clumps falling over her nose like bangs.
5) Rengoku (20 years)
Flame Hashira Rengoku always motivates those around him to become a better version of themselves. He is killed in the Mugen Train arc while fighting against Akaza. It is one of the saddest deaths in the series, but he manages to carry out his duties until his last breath.
12) Tengen Uzui (23)
The Sound Hashira, Tengen Uzui, is the second oldest in the main Demon Slayer cast.
The Insect Pillar of Demon Slayer Corps, Shinobu is undeniably the smartest individual. She might not be physically stronger than others, but her intelligence is what kept her going. Shinobu is proficient in medical knowledge and can also create poisons out of wisteria flowers that are lethal to demons.
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.
The warrior Muzan feared was a swordsman named Yoriichi Tsugikuni. Yoriichi was the only slayer before Tanjiro who came close to killing Muzan, and the flashback of their fight occurred in Chapter 187.
The secret to Gyomei's powers is that they are governed, regulated and enhanced by his emotional capabilities. So in a sense, his crying is a sign of his strength rather than weakness. As a gentle giant, Gyomei's character can be seen as a deconstruction of what makes a person strong in Demon Slayer.
5 Hashiras who end up dying in Demon Slayer (and how it happens) Demon Slayer has showcased many characters that vary in personality, strength, and overall combat abilities.
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.
Gyomei's Nichirin weapon is quite peculiar, as instead of a sword, he has a Flailed Spiked Mace connected with an Axe. However, he could kill a Demon by landing rapid blows until daybreak. Gyomei can defeat Akaza without even awakening his Demon Slayer mark. Akaza is too inferior in front of Gyomei.
Being the flashy and flamboyant man that he is, Tengen has become one of the best and most memorable characters in Demon Slayer. He had a rough start when meeting Tanjiro as Tengen was one of the Hashira that thought he and Nezuko should be executed, but the two of them have come to respect each other.
Unfortunately, even if Nezuko were to fight back against Sanemi's cruelty, she'd probably find herself outmatched. Much like Giyu, Sanemi has encountered and defeated far stronger demons than Nezuko to make his way to the top of the Demon Slayer Corp.
Sanemi is inarguably one of the strongest Hashira in Demon Slayer who has the potential to gain victory over Giyu. Both the characters possess immense speed and endurance, and they also can take on an Upper Rank demon head-on.
Not to mention that no one has been able to kill an Upper Moon in over a hundred years. Uzui and Tanjiro's group breaks the cycle of tragedy when they defeat the Upper Six, Gyutaro. However, it takes one Hashira and several more demon slayers to take down the weakest of the Upper Moon.
