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.
2. Shinazugawa Sanemi – The Wind Hashira.
3 Giyu Tomioka, The Water Hashira.
Gyomei Himejima: The Blind Stone Hashira with Unmatched Strength. Among the Hashira, Gyomei Himejima stands out as the Stone Hashira, with unmatched raw physical strength.
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.
Shinobu Kocho Is the Weakest Hashira
The Insect Hashira, Shinobu's petite frame prevents her from being physically able to decapitate any demon, be it an Upper-Rank or the weakest demon in Japan. At one point or another in the manga, all nine Hashira in Demon Slayer encountered an Upper-Rank.
In his own franchise, Tanjiro is outclassed by most of the nine Hashira as of the end of season 1, including Giyu Tomioka. It's easy to compare Tanjiro's strength to Giyu's — since they are both demon slayers — and they even use the same element: water.
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.
The Water Hashira, Giyu, survived the "Infinity Castle" arc after fighting beside Tanjiro against Akaza and Muzan.
Specifically, Muichiro is the Mist Hashira who made use of the Mist Breathing sword style. He is also the youngest of the Hashira at only 14 years old, being considered a prodigy of the Corps who became a Hashira only two months after joining the Demon Slayers.
Tanjiro's Current Demon Slayer Rank Is Kanoe
Murata, the Demon Slayer, who was almost digested on Mount Nagumo, is also a Kanoe.
7 Obanai Iguro: Serpent Hashira
His fighting style revolves around flexibility and helps him stand out from the crowd. He also has a serpent around him at all times, which makes him even more intimidating. The Serpent Hashira is said to be at least at the same level as the Giyu, the Water Hashira.
Muzan, the King of Demons, is the strongest and also the primal demon in the world of Demon Slayer. Consuming his blood is enough to turn you into a powerful demon. He can control all the demons in existence, with only people with strong willpower like Nezuko being an exception.
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.
Overall, Zenitsu is an extraordinary powerful Demon Slayer capable of singlehandedly bringing down an Upper Rank, which said to be able to overpower 5 Hashira, in 10 minutes, albeit he would have beheaded Kaigaku in a heartbeat if it wasn't for his feelings of melancholy and pity.
Demon Slayers are known for their strength and bravery in battle, but not Zenitsu. Despite his cowardice, he's one of the strongest in the series. The life of a demon slayer is one of hardship. Many who train do not make it through the basics; others die during the final selection.
1) Shinobu Kocho
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.
With all said and done, Tengen Uzui is one of the strongest and most extremely skilled Demon slayer in the series, his physical abilities, combat skills and strategic thinking makes him a tough opponent to defeat in a battle.
The Wind Hashira is one of the strongest Hashiras in the Demon Slayer series. He played a significant role in defeating Kokushibo and was able to inflict damage on Muzan. Sanemi's sheer power and speed will be able to overwhelm Nezuko even in her final form.
1) Kyojuro Rengoku
Unfortunately, Rengoku was killed by Akaza, the Upper Moon 3. This took place when he, along with Tanjiro, Zenitsu, and Inosuke, boarded the Mugen train to investigate cases of missing people.
In the Demon Slayer Corps, the Hashira is a group of the strongest and most reputable swordsmen who have defeated members of the Twelve Kizuki. Yet, for some reason, Tanjiro Kamado, the series' protagonist, never becomes a Hashira.
