Obanai is a very harsh and strict individual who shows no concern for those who do not abide by the Demon Slayer rules. His expectations for his fellow Demon Slayers are quite unrealistic, Obanai has a rather prominent habit of pointing at people with his finger while berating them or talking badly about someone. Obanai is also noted to possess an immense sense of self-loathing due to the fact that he was born to a selfish and immoral clan who would mercilessly sacrifice even newborn children
