Ui Hirasawa

Ui Hirasawa is a character in the series ''[http://kyotoanimation.wikia.com/wiki/K-ON! K-ON!], and its sequel, [http://kyotoanimation.wikia.com/wiki/K-ON!! K-ON!!]''. She is Yui Hirasawa's younger sister. Their parents travel a lot so they are never at home. Ui handles cooking meals and cleaning up for Yui and herself. At the beginning of the series, Ui is a third-year junior high school student, but later she enters the same school as her older sister in high school the following year. Ui is in the same year and class as Azusa Nakano and Jun Suzuki,

Ui is mature, smart, responsible and handles household chores better than her older sister Ui. She has an extreme talent for playing the guitar, and became capable of playing with the rest of the light music club band after only a few days of practice. Sometimes, she teaches Yui how to play some parts of the guitar since Yui is not so good in reading music. Ui is actually considered as the ultimate groupie for her sister's band and supports them with all her heart. She occasionally provides a narrative to the story. Once, she pretended to be Yui when Yui was sick with fever, but failed because she did not know the nicknames the light music club made.
