This is a roughly 13-second excerpt of the Kira theme, taken from its best part and presented in its loud, high-impact form, as a short musical passage built for a dramatic reveal. It feels intense, confident and a little menacing, like a villain stepping into the spotlight at exactly the right second, and it lands best as a brief burst of tension rather than something played in the background.
