Kikirara Vivi, written in Japanese as 綺々羅々ヴィヴィ, is a Hololive VTuber known for her bright, expressive voice and playful greetings to viewers. This long version of her 'Nnn~ Vivi~' call became a shareable clip among fans who cut stream moments into short sounds for edits and reactions. Its appeal is less about a single broadcast and more about recognisability, as the stretched opening immediately signals Vivi before she even finishes her name. Fans still use it online to mark entrances, celebrate favourite moments and add a distinctly cute VTuber flavour.
