Obanai Iguro, the Serpent Hashira from Demon Slayer: Kimetsu no Yaiba, is officially listed as being 162 cm tall, which is about 5 feet 3¾ inches.
Compared to some of the other Hashira, Obanai is on the shorter side, but his compact frame fits his fighting style—swift, precise, and serpentine. His agility and flexibility are key elements in his combat approach, reflecting the snake motif that defines his breathing technique and overall aesthetic.
Despite his smaller stature, Obanai has a commanding presence. His intense gaze, strict sense of discipline, and unwavering loyalty to the Demon Slayer Corps make him feel much larger than his height would suggest. His personality, devotion to the cause, and powerful Serpent Breathing techniques all contribute to his fearsome reputation.
So while he may not tower over others physically, Obanai stands tall through sheer will, skill, and an unshakable sense of duty.
