1. Hated Demon Slayer characters: Muzan Kibutsuji. Muzan Kibutsuji is the primary antagonist of the entirety of Demon Slayer. And while we often want to show grace to premade villains, especially if we don't have all the details, this demon just makes it too easy to despise every single inch of him.
Muzan Kibutsuji is by far the worst of demonkind in Demon Slayer, objectively or otherwise. Everyone, including his most loyal subordinates, is terrified of him, especially in light of his fickle impulses. That said, his unpredictable nature wouldn't have been a problem if he hadn't also been such a malicious monster.
Obanai: Most OVERRATED character in the series, lemme explain. People say "Obanai speedblitz Muzan". Dudes, that was 2nd Drug Muzan. 2nd Drug Muzan was slower than Akaza at that point.
The only Demon he despises the most is the Upper Rank Two: Doma.
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.
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.
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.
Our discontent with Enmu doesn't come from his use of the Infinity Train to devour humans (although that has a role to play in it). It's more how he played heartless mind tricks that would traumatize even the strongest of demon slayers.
Obanai hated Tanjiro with a passion, even more than he hated Giyu. It started with Tanjiro's breach of Demon Slayer conduct and insubordination during the Hashira meeting, but intensified after Tanjiro interacted with Mitsuri during the Swordsmith Village attack and completed her Hashira Training with raving reviews.
Tanjiro harbors a deep hatred for Muzan as he recognizes him as not only the leader and creator of the Demons but also as the perpetrator behind the slaughter of his family using his scent.
While her brother Gyutaro was stronger than her, fans appreciated him for being true to his nature and loving his sister. Daki, on the other hand, had a selfish personality and considered herself to be above everyone else. In one particularly heinous moment, Daki even went as far as to call her own brother ugly.
2 Muzan. From the beginning of the series, Kibutsuji Muzan was established as the most fearsome demon in existence.
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.
Shinobu, the insect Hashira, is one of the fan-favorite female characters in Demon Slayer. She is also the most unique swordsman in the anime. Instead of relying on her physical strength, she smartly uses Wisteria poison (harmful for only demons) to weaken demons and then easily slices their necks with her katana.
The gentle giant of the group, Stone Hashira Gyōmei Himejima has a huge body and an even bigger heart. He is very sensitive, seen crying almost constantly, and soft-spoken.
Gyomei is extremely emotional and caring and is always concerned for those around him. This could be the main reason why he is always crying in the Demon Slayer series.
The Personality of Kyojuro Rengoku
Kyojuro is a trustworthy and kindhearted boy. He is the potential to express his feelings and is quite quirky. However, he also possesses a persistent enthusiasm and amazing bravery that was instilled in him by his mother when he was a young boy.
14 She Has A Really Sweet Relationship With The Hashira Mitsuri Kanroji.
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.
