Azusa Nakano joined K-On as the junior member of the school band Ho-kago Tea Time, and the other girls quickly nicknamed her Azunyan after she wore cat ears and meowed for them. That joke became her defining fan identity, and short clips of her nyan have circulated on anime soundboards and in edits ever since. Like Tuturu, it survives as a tiny, instantly quoted anime girl vocal that fans recognise without any context. Its brevity and sweetness keep it popular for reactions, remixes and cute character tributes online.
