Intro. Iguro Obanai is the Pillar of the Serpent in Kimetsu no Yaiba, recognizable by his facial bandages, heterochromia (yellow and turquoise eyes) and his inseparable snake Kaburamaru, being a cold and strict character with a tragic past of sacrifice and family torture that motivates him to fight demons, using the Breath of the Serpent and a serpentine sword.
