As the Serpent Hashira, Kaburamaru is closely tied to Obanai's representation of his Breathing Technique - Serpent Breathing, a breathing technique which he learned and mastered himself.

But one of the characters that we do not have as much knowledge about is the Serpent Hashira, Obanai Iguro. Apart from a couple of episodes, The Demon Slayer has not come as much to the screens.
