Relationships[]
Family[]
Initially, Obanai had a somewhat positive relationship with his family, as they doted on and pampered him to an extreme degree since the day he was born. The women comprising his clan raised him, fed him the finest, tastiest foods, and kept him in a perfectly secured lattice cell room for his "safety" since birth. While he was completely sheltered, they ensured that he would never want.
However, Obanai admitted that although he was ignorant of the true reason for their over indulgence and extreme protectiveness, he was disgusted by their constant pampering. He greatly hated the excessive amounts of food they would prepare and serve him due to the fact that the foods' strong smells nauseated him, and the insanely secured room's poor ventilation only worsened the problem. The severe isolation that they kept him in also increased his hostility towards his relatives.
Upon learning of the true reason for their overprotectiveness was due to him being their "offering" to their benefactor and source of their immense wealth and prosperity, Obanai became completely disgusted by their greed, selfishness, and amorality. When he ran away to avoid being sacrificed, Obanai feared what the demon might do to his family, but he chose to prioritize his own freedom and safety.
However, after the demon's death, he learned of the mass murder of all fifty of his relatives for their failure to keep him imprisoned. That, combined with the rejection of his last surviving cousin, who blamed him for not letting the Demon eat him, Obanai developed a severe sense of self loathing. He hated himself for being born to a clan of selfish, amoral people and - despite knowing he had no control over their deaths - felt an immense sense of guilt for letting them die to save himself. These crippling emotions prevented him from even trying to find happiness for himself, as he believed he was unworthy of it due to his bloodline and inherent "selfishness".
Unnamed Cousin[]
After the Demon his family had contracted with killed almost all his relatives after Obanai made his escape, only one of his cousins survived the massacre. In the aftermath, she was shown to deeply resented Obanai, attacking and berating him "causing" the deaths of their clanmates. She angrily screamed that he should have allowed the demon to eat him, and had to be dragged away by Shinjuro Rengoku. Rather than reflect on her family's decision to offer people to the demon and taking advantage of the monster's victims for profit, she chose to blame Obanai for her loss.
Obanai himself found her accusation ridiculous given the circumstances and their family's own deplorable actions and justly rationalized that it was not his fault. Despite that, his cousin's words stayed with him and pulled deeply on his heart, manifesting in a strong sense of remorse over his family's demise and guilt for their sins.
Despite her initial attitude against him however, Obanai had always been concerned about his surviving cousin. After asking around, he found out that she was married with children, living a happy and comfortable life with their clan's remaining fortune.
This revelation greatly shocked Obanai. Although he didn't hate her, he both feared and envied his cousin's attitude. Particularly of how she was able to completely ignore the true source of her wealth and continue living in luxury as if the tragedy hadn't occurred and move on with her life. Unlike himself, who was haunted by guilt and self loathing for their clans selfishness and the deaths of their family.
Mitsuri Kanroji[]
Obanai handing Mitsuri her green socks as a gift whilst they ate together.
Obanai is deeply in love with Mitsuri, but his nervousness and the fact that he feels he unworthy of her due to his "filthy blood"[1] keeps him from being forthright. He gives her gifts, keeps correspondence through letters, and is protective of her. While she enjoys the attention he gives her, she seems oblivious to his feelings. However, it is revealed that she likes him, but is afraid to confess.[2]
Obanai tells Mitsuri that he would not let anyone say anything bad about her.
After the battle with Muzan, Obanai is seen cradling Mitsuri's body and, although both were still alive, they could tell that they were to die soon. Obanai reminisces about the first time they met at Kagaya Ubuyashiki's mansion, where Mitsuri saved him by making him feel like a normal young man, which led to him deciding that he would not let anyone say anything bad about her. In the end, Mitsuri confesses that she likes him and that she enjoyed the meals she ate with him. She states that he has always looked at her so gently and asks him if he would take her as his wife if they are reborn as humans again. Obanai replies that if she is fine being with someone like him, then he will definitely make her happy and protect her. This vow eventually happens, as their reincarnations reunite with eachother and marry.
Giyu Tomioka[]
Obanai dislikes Giyu, partially due to his sullen demeanor.[2] Despite this, they work together as allies, and Obanai expresses some concern for Giyu as shown when he defends him from Muzan's fatal attack after the latter loses grip of his blade.
Tanjiro Kamado[]
Obanai helps Tanjiro.
Obanai hates Tanjiro with a passion after his breach of the Demon Slayer conduct and insubordination during the Hashira meeting. This intensifies after Tanjiro interacts with Mitsuri during the Swordsmith Village attack and completes her Hashira Training with raving reviews. However, Obanai eventually shows some warmth towards Tanjiro. He jumps in to protect him after Tanjiro gets slashed in the eye by Muzan, and they fight together against Muzan. After Obanai loses his eyesight from an injury, Tanjiro gives Kaburamaru one of Yushiro's seals that allows Obanai to see what his snake sees, aiding in the battle, and Obanai thanks Tanjiro for his actions.
Nezuko Kamado[]
After Nezuko's presence is revealed to the Hashira, Obanai immediately rejects the idea of a demon fighting alongside the Demon Slayer Corp even after Kagaya's encouragement.
Despite not having many interactions with Nezuko after that, Obanai still displays great distrust towards her and says that he will never accept her as a Demon Slayer as long as she is a demon.
Kyojuro Rengoku[]
Obanai appears to deeply respect Kyojuro and holds him in high regard. He believes he was extremely powerful and expresses disbelief upon learning abut his death.
Tengen Uzui[]
Despite Tengen's victory against Upper Six, Obanai downplays this significant achievement to instead emphasize the extent of his injuries. Tengen, for his part, brushes aside Obanai's concerns, insisting on retiring and disagreeing with the latter's sentiment that the Demon Slayers were going into decline.
Sanemi Shinazugawa[]
Obanai privately converses with Sanemi about their discovery of the Infinity Castle.
Out of the other Hashira, Obanai gets along with Sanemi the best,[2] and the two view each other as good friends. They have positive interactions with each other, such as through accompanying each other on missions, one of which led them to discover the Infinity Castle, expressing their concerns on Muzan attempting to seek out Nezuko and practicing their skills by dueling together during the Hashira Training.
