Use it as the beat after a reveal in an anime edit, then follow with Anime Ahh for the next reaction and JoJo To Be Continued to close the scene on a cliffhanger.
Über diesen Sound
This is a brief voice clip of a speaker stretching out the Japanese word for what into a long, questioning call, lasting just over a second. It lands as bewildered and comic, the sound of someone caught completely off guard by something that makes no sense. It works best as a quick, knowing reaction to confusion, delivered with a raised, incredulous tone.
