Mitsuri. The love Hashira and upcoming featured character of season 3, Mitsuri is best known for her extreme affection for everyone in the Demon Slayer Corps.
Rengoku is easily one of the most lovable Hashira in Demon Slayer. This is why it's a shame that he succumbed to the wounds that he suffered in his fight against Akaza.
From the character popularity polls, Giyuu is the Hashira who manages to rank the highest among the others.
However, Nezuko is the friendliest demon anyone will ever meet. As a human, she was just as outgoing and compassionate. But as a demon, she's proven her loyalty to not only Tanjiro, but to humanity as a whole.
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.
5/14 Fastest Hashira In Running
Despite his large and muscular build, Tengen Uzui is the fastest runner among the Hashira.
2) Gyomei Himejima
The leader of the Hashiras and easily the strongest of them, Stone Hashira Gyomei Himejima, had been blind since childhood but still managed to join the Demon Slayer Corps and attain Hashira status within two months of joining.
Giyu's inferiority complex and survivor's guilt. It is revealed later on that Giyu suffers from an inferiority complex which he developed since his participation in the Final Selection.
14/15 She Has A Really Sweet Relationship With The Hashira Mitsuri Kanroji. In the manga, Nezuko gets to know the Love Hashira Mitsuri Kanroji and looks up to her like an older sister, which makes their relationship interesting since Nezuko usually sees female humans as either a surrogate mother or a young sister.
Sound Hashira
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness. But he is also ultimately kind and caring, with great love for his three wives as well as the other Hashira.
Keen Intellect: Shinobu possesses vast knowledge in using poison in combat. She has one of the best IQ in the Corps, having an IQ of over 200 making her a genius.
The shonen protagonist himself, Tanjiro Kamado, is naturally one of the best characters in Demon Slayer for many different reasons. He is compassionate, brave, smart, loyal, and strong-willed. Tanjiro is also beloved for his remarkable compassion, including his sympathy for dying demons who show their vulnerable side.
As for the "first ever Hashira"...that is unknown. As for the "last ever Hashira"...that would be Shinazugawa-san as well as Tomioka-san.
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.
Nezuko always ranks near the top of fan polls, easily being one of the favorites in the series. Her capabilities steadily progress as the series goes on as she gets a better grasp of her demonic powers, learning to control them.
Who is the crazy Hashira? Sanemi is the most feared Hashira among the Demon Slayer Corps. Sanemi is one of only 4 Hashira who use a normal Nichirin Katana. The other 3 are Kyojuro Rengoku, Giyu Tomioka, and Muichiro Tokito.
Obanai is deeply in love with Mitsuri, as he has stated in the manga.
Nezuko Kamado: Demon Slayer
Inarguably the most popular female anime character is the female lead of Demon Slayer. Despite being turned into a demon, her cute and caring nature towards her brother, Tanjiro, makes her a very easily likable character.
i know, though, some believe he loves hina (21) the most, because he had the most interaction with her in the manga and they have the most “husband-and-wife” feel. we also have to remember that suma (19) was tengen's first chosen wife—they both personally agreed to letting hina and makio (20) into their relationship.
Makio, Suma, and Hinatsuru
Tengen holds a large amount of respect for his wives and cares about them deeply. When Tengen joined the Demon Slayer Corps, he made sure to inform his wives that they needed to prioritize their lives instead of the mission, and make sure to return home to him.
But, when it comes to who was the better Hashira, Tengen wins by a considerable margin. His experiences as a shinobi and as a Demon Slayer far exceeded Rengoku's, and led to him developing far superior strength, battle tactics, and techniques.
