Demon Slayer’s Obanai Iguro is one of the series’ most intriguing Hashira, but he unfortunately does not always receive the appreciation he deserves. Since he can be quiet and reserved due to his tough past, he does not stand out as prominently as other more bubbly and outgoing Hashira like Tengen and Mitsuri. However, he is no less incredible, and his Serpent Breathing powers, determined personality, and willingness to fight until the death for those he loves are noteworthy.
