Obanai Iguro is the Serpent Hashira in Demon Slayer: Kimetsu no Yaiba, known for his masked face, his white snake Kaburamaru and his strict, unsparing attitude toward other Demon Slayers. Short clips like this one circulate on anime soundboards because they let fans reuse a recognisable Hashira voice without needing a full scene. This episode 11 segment is especially handy for edits and reaction content, where a few seconds of Obanai's voice is enough to signal authority, suspicion or cold judgement.
