Place this clip just before the final reveal in a character montage, after the build-up, then follow it with Za Warudo Time Stop and close the edit with JoJo To Be Continued as the screen cuts away.
About this sound
Sebastian Michaelis speaks the Japanese phrase “Akuma de shitsuji desu kara” in a smooth, assured voice over about six and a half seconds, turning a servant's introduction into a quiet threat. It feels elegant and unnerving at once, like a polite smile hiding something dangerous. The line comes from Kuroshitsuji, where Sebastian's double role as demon and butler gives the words their sharp second meaning.
