IA debuted in 2012 as a Vocaloid virtual singer developed by 1st Place, with vocals based on singer Lia. Short IA voice lines circulate widely in anime fan edits, where brief Japanese phrases work as instant character reactions without needing subtitles in context. Nanishiteruno is an everyday question in Japanese, which makes this clip easy to reuse across different scenes. Its popularity comes from that mix of a recognizable virtual voice, a simple meaning, and a delivery that fits comedy, curiosity, and light teasing in short form video.

IA saying nanishiteruno, meaning what are you doing in Japanese, in a cute anime voice clip used for curious and teasing reaction edits and memes.
This is a short vocal clip of IA, the Japanese virtual singer, asking nanishiteruno in a bright, high pitched delivery. The phrase translates to what are you doing, and the repetition in the audio gives it a playful, slightly nosy rhythm. It lasts just over two seconds, long enough to land as a question but short enough to feel like a pop up reaction. Viewers hear curiosity mixed with teasing, as if a character has just caught someone mid action and wants an explanation right away.
