K-On! Character

Yui Hirasawa

(平沢 唯, Hirasawa Yui)
Voiced by: Aki Toyosaki
Yui is the main character of K-On!. She is one of the members of the light music club, and plays a Heritage Cherry Sunburst Gibson Les Paul Classic electric guitar. She does not get good grades in school (though when properly coached, she can achieve astounding results) and is easily distracted by trivialities. Yui is clumsy and easily spaces out most of the time. She takes a huge liking for any kind of food (but admits that she does not gain any weight). She has her younger sister Ui to take care of her and keep herself in line. She has a very easy-going nature, but when hyped, has incredible concentration, though this is only limited to one subject at a time. She will totally neglect any other things in the process, to the point of forgetting anything she has learned beforehand. Despite all of this, Yui is still devoted to her band and will practice hard enough for the club. She has perfect pitch and is one of the group's vocalists , although she is known to forgetting her lyrics at mid-performance, as well as overdoing things, making her unable to perform sometimes.

Ritsu Tainaka

(田井中 律, Tainaka Ritsu)

Voiced by: Satomi Satō

Ritsu (or Ricchan, as nicknamed by Yui) is the president of the light music club and plays a Yamaha Hipgig Drumset. She has an ambiguous yet upbeat personality, and often has trouble remembering important club activities and announcements. Ritsu is cheerful, often likes making jokes and is sarcastic most of the time. She usually brainstorms for ideas to earn more money and for the club's success. She says she chose to play the drums because they are "cool", but in reality, she admits that she has trouble playing instruments which involve intricate finger movements, such as the bass, guitar and keyboard. She is a childhood friend of Mio and will often tease her whenever she is cowering from something and has the opportunity to do so. Ritsu is always on the go and will stop at nothing for the success of the light music club.

Mio Akiyama
(秋山 澪, Akiyama Mio)
Voiced by: Yōko
HikasaMio is a shy girl who is in the light music club and plays a left-handed, 3-Color Sunburst Fender Precision Bass (Fender Jazz Bass in the anime), with a tortoiseshell pickguard. She originally intended to join the literary club, but is forced into the light music club by her childhood friend and the club's drummer, Ritsu. She gets excellent grades in school, but is bad with listening to stories involving macabre experiences, and cowers whenever something gross is brought up. While she can be mature and strict sometimes, she gets embarrassed easily, and is often teased by Ritsu and Sawako, their club adviser. She cites that she chose bass since it is not the center of attention in the band, unlike the guitarist (though being the vocalist somewhat negates this). Mio is more technical when it comes to music, and Yui often comes to her when she is in need of more guitar tutorials. She is the main vocalist in the group and also writes the songs, although they feature some odd lyrics like "Light and Fluffy Time". She is left-handed and is fascinated by other left-handed bass guitar players. Due to an unexpected accident in one of their live performances, a fan club for her is then made (much to her dismay considering the circumstance).

Tsumugi Kotobuki
(琴吹 紬, Kotobuki Tsumugi)
Voiced by: Minako
Kotobuki Tsumugi, often referred to as 'Mugi' by her friends, is a wealthy girl with a gentle and sweet personality who plays a Korg Triton Extreme 76 Key keyboard in the light music club. Tsumugi is considered a piano prodigy since she has been playing the piano since she was four and has experience in winning various piano contests. She is the daughter of a company president, and her family has several villas in various places around Japan. She often brings confectionery and an assortment of sweets and pastries to the club room, and she diligently makes tea with a tea set which is kept in their club room. Although she is a sweet and gentle girl, she is often weirdly entranced by the sight of two girls interacting closely together, sometimes imagining something more risqué in her head (both Mio and Ritsu find this awkward at times). She originally intends to join the choir club, but joins the light music club instead after receiving an invitation and encouragement from both Mio and Ritsu.

Azusa Nakano
(中野 梓, Nakano Azusa)
Voiced by: Ayana Taketatsu
Azusa is a new student who joins the light music club and plays a Fender Mustang electric guitar. She is in the same year and class as Ui and has quite a mysterious demeanor. She is a self-proclaimed novice guitarist who has been playing the guitar since she was in the fourth grade, and her parents are working in a jazz band. She often finds herself bewildered by the tea parties and cosplaying aspects of the club, when she would rather just practice and is curious on how the club is able to play so well despite their problems and lack of practice. However, she has a certain weakness for cakes and can be calmed down rather easily, sometimes by just being petted. She is constantly hugged by Yui and is nicknamed Azu-nyan after trying on a pair of cat ears and meowing. In the band, she looks up to Mio the most due to her maturity and the fact that she is an experienced bassist. Since joining, Yui comes to her for advice on playing guitar, as well as maintenance.
