the late night walk scene sets a genuinely eerie tone

there's something about being grouped with Zenitsu, Tanjiro, and Inosuke, all quietly grieving, and then just — a voice cutting through the dark asking what's a human like you doing out here late at night. it doesn't announce itself as a big threat right away, it just sits there being unsettling. the mood carries the whole opening more than any single line does. felt less like meeting a boss character and more like being watched by something that already decided how the conversation ends.
