A bright anime-style voice blurts “oh my gah” in one quick, clean burst lasting about 1.4 seconds. It sounds flustered and over-the-top, caught between surprise, embarrassment and dramatic disbelief. That instant, readable reaction turns an awkward reveal or sudden fail into something playful instead of serious.
