Put this clip near the start of an anime reaction edit, just before the main joke lands, then follow it with Onii-chan Onii-chan for a doubled greeting and Anime Ahh as the follow-up reaction to the same character.
关于此声音
This is a short 3.5-second anime voice clip centred on the word 'onii-chan', spoken in a warm, playful tone that feels affectionate and a little teasing. It gives a cute, slightly awkward lift, like a sweet greeting arriving out of nowhere, and it works as a quick burst of charm that makes a listener smile.
