Vivienne (びびあん) is an utaite who has been uploading covers since mid-2008. She has a thin, stringy and bouncy voice which can hit high notes very well, and she has the ability to scream well in her covers; therefore, she has one of the most well-known Rin-type voices, and often plays the Rin part during collabs for songs such as Mr. Music and Juvenile. She originally started her career by posting slower, more tame songs, but over time, she moved to singing faster-paced, upbeat, and high-intensity songs.
