The reason he might hate Giyu is because of his expressionless personality, Sanemi could take it as ignorance. So, Giyu Tomioka is not really hated by all other Hashiras except one or two. Comment down what do you think about his personality and also share this post with your friends.
They have opposite personalities and initially seem to be at odds with each other. Giyu was shocked when she claimed he just had a grudge on her for saying the others hated him. Despite being at odds with each other, she is the only Hashira who Giyu has interacted with and talked to cordially.
Giyu's stoic and emotionless disposition. Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives.
Living with guilt and doubting one's own skills can be very harsh. This could be the main reason why Giyu Tomioka isolated himself since he felt like he didn't belong there. He thought that it was Sabito's, and to a smaller extent, his sister's, efforts that allowed him to become a Hashira and not his own.
At one point or another in the manga, all nine Hashira in Demon Slayer encountered an Upper-Rank. 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.
Throughout the series, however, the character has never exhibited any interest in anyone other than Koucho Shinobu. Despite the fact that the two characters are adored by a large audience, Giyu could not have wedded Shinobu because she died after her battle with Douma.
Inside of Limbo, Doma, having heard and been touched by Shinobu's strong faith and belief in her comrades and fellow Demon Slayers' ability to defeat the demons and slay Muzan, seemingly begins to develop genuine feelings of romantic attraction towards Shinobu.
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.
Zenitsu also protects Nezuko multiple times when she is in danger, evident during Zenitsu's first meeting with Inosuke Hashibira and the battle against Enmu in the train. Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
Upon seeing her for the first time, Zenitsu falls in love with Nezuko at first sight. She apparently views Zenitsu as a "weird dandelion" and did not initially seem to reciprocate his feelings. Although the two are rarely seen interacting together, Zenitsu treats her with affection and care.
Fans have wondered whether Zenitsu ever got to realize his dream of becoming a Hashira at all. Unfortunately, the answer to this question would be, no, he did not. Zenitsu, along with Tanjiro and Inosuke got way stronger than average corps members with training.
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.
Shinjuro saved a young Obanai Iguro from the Serpent Demon and reunited him with his cousin. Nonetheless, due to his cousin's attitude, Shinjuro had to separate them. Before retiring as the Flame Hashira, Shinjuro tore apart the Generational Flame Hashira Record of the Rengoku family.
Shinobu and Giyuu are not implied to be a couple, but some think the way they interact with each other is endearing in a "bickering couple" kind of way. Despite Giyuu looking serious, he has an aloof and airheaded personality that people don't like.
Sabito was indeed stronger than Giyu. He spent the entire final selection saving his fellow demon slayers. Giyu admitted that if Sabito survived the exam, he'd likely be the Water Pillar instead. In chapter #131, Tanjiro became tasked with convincing Giyu to participate in the Pillar Training sessions.
