Put it near the end of a short anime reaction, right after the reveal that prompts the call, then follow it with the Awkward Moment Sound Effect to keep the joke going, or lead into the Yamete Kudasai Sound for a second anime reaction.
इस साउंड के बारे में
A short 2.8-second anime voice says “oh, onii-chan” in a bright, exaggerated tone, using the Japanese word for an older brother. It feels cute, dramatic and deliberately awkward, landing as a playful tease or a flustered reaction rather than a serious call. Its compact timing makes the line instantly recognisable in edits and reaction moments.
