Ceres Fauna is a VTuber from hololive English who debuted in 2021 as part of the Council generation, known for a calm, nature-themed persona and ASMR-leaning streams. Okaeri, short for okaerinasai, is the everyday Japanese reply said to someone returning home, often paired with tadaima from the person arriving. Clips of Fauna using the greeting spread through stream highlights, fan edits and soundboards because the short line captures her gentle hosting style. It remains popular for welcome-back moments, homecoming jokes and soft anime-style greetings online.
