This is a short voice clip of Muzan speaking in a low, controlled tone that lasts just under five seconds. It feels cold, threatening and quietly superior, like a villain who never needs to raise his voice to be obeyed. The line comes from Demon Slayer, where Muzan Kibutsuji is the main demon antagonist.
