Place this clip at the climax of an anime power-up edit, right after the build-up peaks. Open the sequence with Za Warudo Time Stop for the setup, follow with this declaration, then let Giorno Giovanna's Theme carry the victory montage that follows it.
About this sound
This is a four-second anime voice clip of Shirou declaring Nine Lives Blade Works, his all-out blade technique, delivered as a forceful shouted attack call. It feels intense and determined, like the split second before a fighter commits everything to one decisive strike with no way back.
