Nyanpasu is the signature greeting of Renge Miyauchi in Non Non Biyori, a slice-of-life anime that first aired in 2013, where the young character combines a cat-like meow with a cheerful hello. Fans turned the greeting into a recognisable meme sound, sharing it in anime edits, reaction videos and short-form clips long after the show aired. Its short length and childlike charm keep it useful as a quick, wholesome cue, especially for creators who want a light, cute moment without a longer voice line.
