Yui Hirasawa is the main protagonist of K-ON! She is the guitarist and lead vocalist of Houkago Tea Time. She is air-headed, and she joined the Light Music Club thinking it meant "easy music", thus picking up her guitar, which she nicknamed "Geeta", with absolutely no prior experience. She likes cute things and sweets brought by Mugi. She, along with the rest of the Light Music Club, also appeared in Hollywood World and Full Moon's Full Pokemon Journey.
