Yui Hirasawa (平沢 唯)
Height: 156 cm
Weight: 50 kg
Blood Type: O
Birthday: November 27
Favorite Music: Yui doesn't follow any particular style, and isn't picky. As long as she likes it, anything is OK.
Experience with musical instruments: None.
Family Structure: Family of four, both parents and younger sister (Ui). Father works for a trading company, gets a lot of overseas assignments and tends to be absent. Because the mother often travels overseas too (helping the father), the daughters have many opportunities to spend time alone together.
Dwelling: Single family detatched home.
Commute to school: Walking.
Preferences in clothing: Pants over skirts. Yui is relatively fashion conscious and likes styles featured in teen magazines. She also wears casual clothes such as shorts and T-shirts at home.
Her room: Clean, because Ui cleans it. Yui likes small cute things, and keeps stuffed toys and such in her room. The room is painted in girly pastel and pink tones.
Favorite food: Anything, as long as it's sweet and delicious.
Subjects she is good at: Between low and average and can rarely pass test easily, but has a hard time with questionaires.
Subjects she is bad at: All of them

Way to pass time when alone: Lazing around at home.
Weaknesses and dislikes: Studying.
Main character, guitarist, lead vocalist. Having misunderstood that "light music" equals "easy music" (like whistling), she joined the Light Music Club and picked up guitar with absolutely no prior experience. She is the type of person who doesn't read manuals and relies on her own intuition and self taught approaches.
Yui is a girl who's easily distracted by cute things and tasty food. She's a crybaby but cheers up easily if she gets some sweets. She eats a lot of sweets but she does not gain as much as she eats, she said to herself. In many ways some may say she's a child, and making sure she practices is a problem. When Yui takes good care of something, like her electric guitar- Gitah, she sleeps with it, plays dress up with it, and even also have tea time with it. When she wants to remember something, she forgets everything else. Yui's energy seems to come from cake. She is a clumsy, scatterbrain but optimistic and kind-hearted.
Yui gets good grades in school but is easily distracted by trivialities. She has her younger sister Ui, who is very mature and acts as the "older sister" of Yui, to take care of her and keep herself in line. She has a very easy-going nature, but has incredible concentration when hyped, though this is only limited to 3-4 subjects at a time. Despite all her flaws, Yui is still a fundamentally good-hearted girl who openly expresses love with hugs, holding hands and adorable nicknames (most notably "Azu-nyan" for Azusa), and once devoted to something she is loyal to a fault, and can display near-genius levels of competence to the subject of devotion, as shown by her perfect score in the makeup exams to return to the band. She has perfect pitch and thus can tune her guitar by ear flawlessly. She is the group's main vocalist, although she is known to forget her lyrics in mid-performance, as well as overdoing things, making her unable to perform sometimes. She is the sort of person who learns by being shown, rather than by having read about it. Yui shows this lack of technical knowledge when she does not know what a palm mute or vibrato is when Azusa suggests the use of one when teaching her, but could use one in her music.

Mio is a shy girl who is in the light music club. She plays a left-handed, 3-Color Sunburst Fender Jazz Bass with a tortoiseshell pickguard, though is shown playing a Fender Precision Bass in the first manga volume. She uses D'Addario EXL160M medium bass strings. Her bass is given the name Elizabeth later in the anime. While she originally intended to join the literary club, she was forced into the light music club by her childhood friend and the club's president/drummer, Ritsu. She gets excellent grades in school and is often mature and strict especially where Ritsu is involved; her weakness is the macabre and horrific, and she is often incapacitated with fear when stories involving ghosts, blood, injuries, haunted houses, barnacles or other disturbing topics come up. She also has a fear of being in the spotlight and gets embarrassed easily, and is often subject to teasing from Ritsu and Sawako, their club adviser and eventual third-year homeroom teacher. Mio has long, straight black hair and gray eyes (that are angled slightly more than the other characters). She cites that she chose bass since it is not the center of attention in the band, unlike the guitarist. Mio is more technical when it comes to music, and Yui often comes to her when she is in need of more guitar tutorials.
Along with Yui, Mio is one of the band's main vocalists, though given her dislike of being center stage, she tries to avoid taking the lead vocal if possible, generally singing if Yui is unable to. She writes most of the songs, although they usually feature some odd and overly girlish lyrics like "Light and Fluffy Time". As she is left-handed, she becomes entranced whenever she sees left-handed instruments, because of their rarity. After their first live performance, the attractive Mio gained a huge fan following (in no small part due to an unfortunate accident that occurred at the end of the show), led by an infatuated former student council president. Also resulting from her sudden popularity, most of her classmates voted that she portray Romeo in their class play. Mio comes to greatly enjoy her time at university as she encounters many new experiences She is also able to overcome some of her shyness and make new friends such as Sachi and Ayame.
Ritsu Tainaka (田井中 律)
Birthday: August 21

Dwelling: Single-family detached home.
Commute to School: Walks (her house is in the same neighborhood as Mio's).
Preferences in Clothing: Pants over skirts. She likes to wear polo shirts.
Her Room: Messy to the point that there is no place to stand. Half-finished manga and snacks are scattered around. She tidies it up before it becomes a full-blown disaster, but it immediately becomes a mess again.
Favorite food: Rice. Rice comes before snacks. She values food that fills the belly.
Subjects She is Good at: Physical Education.
Subjects She is Bad at: Everything else.
Physical exercise: Her strong point.
Way to Pass the Time When Alone: Reading manga.

Ritsu (or Ricchan, as nicknamed by Yui) is the self-proclaimed president of the light music club and plays a yellow Rick Marotta Signature Yamaha Hipgig drum kit with an add-on floor tom (in the opening credits only) combined with a cymbal set from Avedis Zildjian,though is shown playing a white Yamaha Absolute Series drumkit in the anime's closing credits.She has an ambiguous yet upbeat personality, much like Yui, but often has trouble remembering important club activities and announcements and gets constantly rebuked by Mio and Nodoka for forgetting to send in important forms concerning the club. Ritsu is cheerful, often likes making jokes and is sarcastic most of the time. She is skilled at brainstorming ideas that earn money for the club. Ritsu has shoulder-length, brown hair, with her bangs pulled back with a yellow hairband, and gold-colored eyes. She wears her school jacket open. She says she chose to play the drums because they are "cool", but she then 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 take the opportunity to tease her whenever Mio is cowering from something. She is also known to become easily jealous of Mio's other high school friends, even going as far as spying on Mio when on outings with them. Ritsu is always on the go and will stop at nothing for the success of the light music club. Despite her rough mannerisms and speech, she gets cast as Juliet by the majority of her classmates in their class play rendition of Romeo and Juliet and, in the end, manages to act like a proper girl. In the anime, she states her favorite drummer is Keith Moon of The Who. She is skilled at cooking. She has a younger brother named Satoshi.

Her room: Canopy bed, antique furniture and such, as expected of a rich girl's room. The room is decorated mostly according to her parents' tastes.

Weaknesses and dislikes: She is a little worried about her predisposition to gain weight easily.
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, though she is also seen playing a Korg RK-100 keytar in the closing credits of the first season. She originally intended to join the choir club, but joins the light music club instead after receiving an invitation and encouragement from both Mio and Ritsu.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. Mugi has long, pale blonde hair, blue eyes, unusually large eyebrows, which apparently run in her family and a fair complexion that the other characters do not have, but she does not get sunburned. She is the daughter of a company president, and her family has several villas in various places around Japan (and even one in Finland).Since her father also owns a maid café, 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. Despite her wealth, she is fascinated by and finds joy in "normal" activities, such as ordering fast food, sharing french fries with her club mates,holding down part-time jobs and haggling over prices.Tsumugi displays a rebellious streak occasionally, diverting from her normally well-behaved and mature demeanor to the surprise of the others. She also displays a childlike eagerness from time to time, and possesses unusually high strength, being able to effortlessly carry around her own keyboard, Ritsu's drums, amplifiers, and at one point beating an arm-wrestling game in an arcade.
Tsumugi is often entranced by the sight of two girls interacting closely together, sometimes imagining something more risqué in her head. The series sometimes indicates that Mugi has a crush on their teacher, Sawako Yamanaka. While a lot of things do not bother her, she is fairly conscious about her weight (just like Mio), and she gets a bit anxious when her family's staff start spoiling her friends during villa visits. She later begins learning how to play the guitar from Azusa. Tsumugi has a childhood friend several years younger than her named Sumire Saitō who is a daughter of the family that serves the Kotobuki household. Tsumugi grew up home schooled, and therefor spent very little time in the outside world. Because of their close friendship Sumire would purchase everyday items like manga for Tsumugi that she was not normally allowed to see. Tsumugi was rather taken by some of the yuri manga she received which may have influenced her later perceptions about relationships. When Sumire started high school, Tsumugi wanted her to experience the light music club on her own, but due to Sumire's shyness Tsumugi came up with the excuse to send her to the club room to pick up the tea sets that had been left there and told Sawako when Sumire did join that it was okay to leave the tea sets there.
Azusa Nakano (中野 梓)
Birthday: November 11
Blood type: AB
Azusa is a new student who joins the light music club and plays a Fender Mustang electric guitar but she is also in possession of a Gibson Les Paul Custom 50th Anniversary Gold Top (as seen in episode 13). A self-proclaimed novice guitarist who has been playing the guitar since the fourth grade and whose parents are working in a jazz band. She is in the same year and class as Ui and has quite a mysterious demeanor. 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 could be described in part as a tsundere. 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.
