Kuri-na! (けいおん!) is a Japanese four-panel comic strip seinen manga written and illustrated by Kakifly. The manga was serialized in Houbunsha's manga magazine Manga Time Kirara between the May 2007 and October 2010 issues. It was also serialized in Houbunsha's magazine Manga Time Kirara Carat. The manga relaunched from April 2011 to June 2012 with two separate storylines published in Manga Time Kirara and Manga Time Kirara Carat. The manga is licensed in North America by Yen Press.

A 13-episode anime adaptation produced by Kyoto Animation aired in Japan between April and June 2009. An additional original video animation (OVA) episode was released in January 2010. A 26-episode second season, titled Kuri-na!! (with two exclamation marks), aired in Japan between April and September 2010, with an OVA episode released in March 2011. An animated film based on the series was released in Japan on December 3, 2011. Bandai Entertainment had licensed the first season until their closure in 2012. Sentai Filmworks has since re-licensed the first season, in addition to acquiring the rights for the second season and film. The title of the series comes from the Japanese word keiongaku (軽音楽), which means popular music. Kuri-na has achieved strong sales in Japan, and by 2011 gross revenues had reached over 15 billion yen.

Plot
In Kuri-na in an unspecified part of Japan, four Japanese high school girls join the light music club of the all-girls private Sakuragaoka High School to try to save it from being disbanded. However, they are the only members of the club. At first, Yui Hirasawa has no experience playing musical instruments or reading sheet music, but she eventually becomes an excellent guitar player. From then on, Yui, along with bassist Mio Akiyama, drummer Ritsu Tainaka, and keyboardist Tsumugi Kotobuki spend their school days practicing, performing, and hanging out together. The club is overseen by music teacher Sawako Yamanaka who eventually becomes their homeroom teacher as well during their final year of high school. In their second year, the club welcomes another guitarist, underclassman Azusa Nakano. After Azusa joins they gain more structure and begin to practice more.

After their third year, Yui, Mio, Ritsu and Tsumugi graduate and enroll into a university. There they join its light music club alongside three other students: Akira Wada, Ayame Yoshida, and Sachi Hayashi. Meanwhile, Azusa continues to run the high school light music club alongside Yui's sister Ui, their classmate Jun Suzuki, and new members Sumire Saitō and Nao Okuda.

Main characters

 * Hirasawa Yui (平沢 唯)
 * Yui is the main protagonist of the series. She is one of the members of the light music club and plays a Heritage Cherry Sunburst Gibson Les Paul Standard electric guitar (before she knew how to play the electric guitar, the only instrument she knew how to play was the castanets) that she nicknames "Gīta" (ギー太). She does not get good grades in school (though when properly coached, she can achieve astounding results) and is easily distracted by trivialities (mainly those deemed cute and adorable). Yui is clumsy and easily spaces out most of the time; as a result, she can be forgetful and is sometimes oblivious to the situation around her. Yui has shoulder-length, brown hair (a little longer than Ritsu's) which she accessorizes with two yellow hair clips, and brown eyes. She takes a huge liking for any kind of food (though she never gains weight, which is greatly envied by Mugi, Mio, and Sawako ). She has a younger sister named Ui, who is very mature and acts as the "older sister" of Yui, taking care of her and keeping her in line. Yui works extremely hard to get better at playing guitar. During performances, Yui plays with amazing energy and joy which usually results in great response from the audience.

 * Yui is the band's main vocalist and lead guitarist and has absolute pitch—she can tune her guitar perfectly without a tuner, which greatly impresses Azusa, who has played the guitar much longer than Yui. She has a very easy-going nature, but has incredible focus and retention when she has a clear goal in sight; unfortunately, this is limited to only one subject at a time, and her other skills deteriorate quickly (for example, Yui is at one point pressed to make up failing test scores, and she quickly brings her math skills up to par at the expense of her guitar knowledge). Despite all of this, Yui is still devoted to her band and will always practice hard enough for the club. At school, she has become quite admired for her great voice. However, she is known to forget her lyrics mid-performance as well as overdoing things, making her unable to perform sometimes. Mio was the lead vocalist at first, since Yui could not play the guitar and sing at the same time.  Yui is also known to write childish lyrics as Ui has assisted her in creating them.


 * Akiyama Mio (秋山 澪)
 * 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 (エリザベス) 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 horrific; 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.

 * Mio is the second vocalist of the band, 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.


 * Tainaka Ritsu (田井中 律)
 * Ritsu (or Ricchan (りっちゃん), as nicknamed by Yui) is the self-proclaimed president of the light music club and the leader of After School Tea Time who 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 later admits that she has trouble playing instruments which involve intricate finger movements such as the bass, guitar and keyboard.

 * She is Mio's childhood friend 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 (聡).


 * Kotobuki Tsumugi (琴吹 紬)
 * Tsumugi, often referred to as Mugi (ムギ) 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, and a Hammond organ in the closing credits of the second 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. Tsumugi has written several songs for the light music club, as well as singing the back vocals in several other songs. She is a good student and has long, pale blonde hair, blue eyes, unusually large eyebrows that 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 therefore spent very little time in the outside world. Because of their close friendship, Sumire would purchase everyday items for Tsumugi, like manga 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 of sending 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.


 * Nakano Azusa (中野 梓)
 * Azusa is a student in the same year and class as Yui's sister Ui, who joins the light music club and becomes the rhythm guitarist, playing a Fender Mustang electric guitar. She eventually names her guitar Muttan, as it is a Mustang. 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 is more serious than the other girls, and does not like to admit how she really feels. She often finds herself bewildered by the tea parties and cosplaying aspects of the club, when she would rather just practice, and is curious about 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 a victim of Yui's skinship and is nicknamed Azu-nyan (あずにゃん) after trying on a pair of cat ears and meowing ("nyan" being the equivalent of "meow" in the Japanese vocabulary). Despite this, Azusa is not too good with cats. Azusa has long black hair, which she wears in pigtails, and brown eyes. While Azusa is talented in guitar, she has trouble singing while playing unlike Yui and Mio.

While Azusa is talented in guitar, she has trouble singing while playing unlike Yui and Mio.


 * In the band, she looks up to Mio the most due to her maturity and the fact that she is an experienced bassist, even trying to give Mio chocolate on Valentine's Day. However, she sometimes unintentionally makes remarks concerning Mio's weaknesses, such as her weight. She also finds Mugi very beautiful, and envies her hair and large eyes, and later starts teaching her how to play guitar when the two are alone in the club room. Since joining, Yui comes to her for advice on playing guitar, as well as maintenance. She gets a tan extremely easily, once during their time at the beach and another during a music festival (even after applying sunscreen). As a result, she frequently gets sunburned as well. She gets lonely very easily, and often worries that everyone in the club will leave her, as they are one year older and eventually will graduate. Due to this, the rest of the girls buy her a turtle to look after, naming it Ton.


 * Outside of the band, she often hangs out with Ui and Jun whenever the other girls are busy. When the others graduate, she becomes the new light music club president alongside Ui and Jun, who decide to join her. Together with two new members, Sumire and Nao, they form a new band called "Wakaba Girls" (若葉ガールズ). During the Wakaba Girls' first summer training camp Azusa reveals to Sawako her belief that she is unable to act like a proper president for the light music club; however, Sawako suggests that there is no proper way to define what it means to be a president and that Azusa will do just fine. While on that same training camp Azusa is convinced by the others to become the band's vocalist despite her prior reservations on the issue.

Supporting characters

 * Yamanaka Sawako (山中 さわ子)
 * Sawako is a music teacher who is the adviser for the wind instrument club at the girls' school. An alumna of the school and a member of the light music club in her student days, she does not want people to find out that she was formerly a member of a heavy metal band called Death Devil (of which she was both lead guitar and vocalist and went by the stage name of Catherine (キャサリン) ), thus she covers up by being mild and gentle to her coworkers and especially to students. She is forced to be the adviser of the light music club, as Ritsu blackmails her after the girls learn of her past. However, she is able to juggle being the adviser for the wind instrument club as well, even as the story progresses. Though she has a mature and gentle demeanor in the school, Sawako (affectionately addressed as Sawa-chan (さわちゃん) by both Ritsu and Yui) displays a totally different, completely authentic character when she is alone with the light music club. In reality, she is rather wild, lazy, and is quite an irresponsible teacher who enjoys dressing up the light music club in (sometimes embarrassing) cosplay costumes (like French maid uniforms), much to the dismay of Mio. She gets a thrill out of the rare moments where she is praised for her work.

 * She names the club band "Ho-kago Tea Time" after the members take too long deciding on a name themselves. In the anime, she once pitches in for Yui with her white Epiphone "1958" Korina Flying V electric guitar. She becomes the girls' homeroom teacher in their third year, and puts Nodoka and all the band members (except Azusa, since she is a grade lower) in the same class, so she does not have to remember as many names. An episode in the second anime season reveals that she owned one of the first Gibson SG models (from around 1960 with a custom stoptail bridge) which is later sold. Due to her relation to the club members, the other students in her class start to call her Sawa-chan as well, ruining her image as a mild-mannered teacher. Her image is further ruined after Death Devil is temporarily reunited at a wedding reception for a high school alumnus. Regardless, her popularity with the students remains unchanged. In spite of her laziness, she still proves herself to be an able mentor, as shown by her willingness to coach Yui as the lead singer and attending their performances. Her music abilities apparently have not dulled over the years, as she is able to substitute for Yui at the school festival at almost no notice without the assistance of a music score, even without any prior practicing of the band's song. Sawako is also very perceptive: she immediately sees through Ui's disguise when she impersonates her sister and on several occasions boasts to the club that there is nothing she cannot see.


 * Hirasawa Ui (平沢 憂)
 * Ui is Yui's younger sister, who begins the story as a third-year junior high school student, but later enters Yui's high school the following year in the same class as Azusa. Unlike her older sister, Ui is mature, responsible, and handles household chores well. Despite these differences Ui shares a very strong relationship with Yui and has a great deal of love and admiration for her older sister that sometimes borders on a sister complex. She takes particularly good care of Yui and strives to look after her even at risk to her own health. Ui is considered to be the ultimate groupie for her sister's band and supports them with all her heart. She occasionally provides a narrative to the story. Despite being a year younger than Yui, she is nearly identical to her older sister with her hair down and is even able to fool members of the light music club on more than one occasion. However, Sawako Yamanaka can tell Yui and Ui apart easily, saying 'their bust sizes are completely different'. Ui is a fast learner, able to learn how to play the guitar after only a few days' practice. She is also able to play the organ if needed.  She eventually joins the light music club along with Jun at the end of the series, becoming a guitarist like her sister, playing a Surf Green Fender Stratocaster electric guitar. Ui becomes fascinated with Sumire's sister-like relationship with Tsumugi upon learning of it, as Ui sees it as very similar to her feelings toward Yui.

 * Manabe Nodoka (真鍋 和)
 * Nodoka is Yui's childhood friend and confidant who is a member of the school's student council. As a normal, well-mannered and intelligent girl, she is generally taken aback by the light music club's odd behavior, and easily gets annoyed with Ritsu whenever she forgets to fill in the club's application forms. She shares the same class as Mio in their second year, who appreciates her companionship tremendously, she being the only person Mio knows in her class. In her third year, she replaces Megumi Sokabe as the student council president and the Mio fan club president as well (after a while), the latter at Megumi's request. In her third year, she shares a class with the rest of Hokago Tea Time. Nodoka chooses to go to a national university as opposed to the same college as Yui and the others.

 * Suzuki Jun (鈴木 純)
 * Jun is an outgoing girl and a friend and classmate of both Azusa and Ui from before they joined the light music club. Ui at first tried to get Jun to join the light music club but ultimately failed due to a strange visit to the club room. Thanks to this experience, Jun stayed in the Jazz club instead. While there she played a Yamaha Sbv500 bass. Jun became one of Mio's admirers because they both play bass.  Jun begins to regret not joining the light music club when she hears about all the activities they do and eventually joins the light music club at the end of the series. She attempted to play the guitar but she did not feel that it suited her. She has an older brother named Atsushi who also plays bass and regularly gives Jun lessons. Jun was embarrassed when the light music club found out that she was receiving these lessons because she felt it damaged her image as a person who could learn an instrument on their own. Jun owns a pet cat in the anime series.

 * Saitō Sumire (斉藤 菫)
 * Sumire is a shy blonde girl who meets Azusa, Ui and Jun after Yui and the others graduate. She is a freshman, two years below the other light music club members. She is currently working in the Kotobuki household as a maid and originally came to the light music room to try to retrieve Tsumugi's teaset that was left behind after she graduated. After being scared off a few times by Sawako, she eventually agrees to join the light music club and eventually becomes its drummer. Similar to Tsumugi, she is quite talented at preparing tea, but feels inclined to keep her role as a maid a secret from the others due to the fear of being punished by Tsumugi. As her family, who came from Austria (Australia in the manga), were taken in by the Kotobuki household before she was born, Sumire grew up as Tsumugi's playmate, often regarding her as her older sister and inadvertently sparking Tsumugi's interest in yuri by introducing her to manga of that genre. As she grew up and learned the truth about the relation between the two families, Sumire felt she needed to regard Tsumugi with more respect while in public. Sawako reveals that Tsumugi asked that the tea sets be left in the club room. However, before the beginning of the new term Tsumugi had asked Sumire to remove the tea sets thereby ensuring that Sumire would encounter the other members of the light music club and would be invited to join. Sumire's situation is revealed to the surprise of the other members of the club by Sawako. Sumire uses her close ties with the Kotobuki family to reserve the use of their largest seaside villa for her first summer training camp with the light music club.


 * Okuda Nao (奥田 直)
 * Another freshman in the same class as Sumire. Generally poor at physical activities, Nao goes through several trial runs through various clubs before deciding to join the light music club, as she feels it is where she can try her best. Like the kanji in her name, she is overly honest about her shortcomings. After reading up on music theory, she ends up having an advanced knowledge of music but lacks the ability to physically play it. However, when she is introduced to music creation software, she decides to become the band's producer. She is the oldest among the five siblings in her family. When on her first training camp with the Wakaba Girls, Nao writes the lyrics for the band's first song, titled "Answer". She wrote the song to reflect Azusa's misgivings about her role as president of the light music club. Okuda remarks that she keeps track of all her band mate's conversations and behaviors by entering her observations into her computer, therefore she was able to describe Azusa's exact feelings in her lyrics.


 * Wada Akira (和田 晶)
 * A new character introduced in the restarted manga who is in a band called OnNaGumi (恩那組) with her friends Ayame and Sachi. Akira joins the university's light music club alongside Yui and her friends. She has short black hair and often looks intimidating whenever her hair is messy.

K-On! has influenced a string of tourism for the rural town of Toyosato, related to the phenomenon of the anime pilgrimage, home to the elementary school that was used as a model for the high school in the anime. The school has opened portions of itself to the public as an exhibit for the series. Matthew Li of Anime Tourist described the exhibit as, "A place that genuinely understands its fanbase and carries all the sentimental props one can remember from the show and more; housing items seen in the school, like a museum." The anime has also inspired real-life musicians. Hiroto, the bassist of The Sixth Lie, joined a band that was influenced by K-On! when he was in junior high school.
