Hello everynyan comes from Azumanga Daioh, the slice-of-life anime based on Kiyohiko Azuma's manga, where Chiyo-father is the mysterious yellow companion who follows the young student Chiyo Mihama. The greeting plays on the Japanese word nyan, meaning meow, turning a simple hello to everyone into a cute cat-themed pun that fits the character perfectly. Clips of the line spread through anime forums, video compilations and soundboard sites, where fans kept sharing it as a wholesome anime greeting. Its short length and instantly recognisable voice keep it popular for intros, memes and friendly edits.
