Put it near the end of a scene, after the provocation has played out, so it acts as the turning point. Lead in with Eh Eh Ehhhh to show disbelief, then let this clip answer it, and follow with Awkward Moment while everyone processes what just happened.

This is a short Japanese voice clip of Nanami snapping in genuine anger, running for just under seven seconds with a sharp, raised delivery that leaves no room for doubt. It feels tense, confrontational and strangely satisfying, like hearing a calm person finally reach their limit. The outburst lands as both a warning and a release, making it easy to recognise even without understanding every word.
