K-ON! is a comedy anime created by Kyoto Animation and Pony Canyon, the company with the single manliest name ever. K-ON! is about the Sakura High School light music club (in Japanese Keione) and their misadventures.
Yui Hirisawa enters high school looking to get involved with something because school spirit kicks ass. Because she sucks at sports and isnt good at anything else she joins the Light Music club. The Light Music Club needed a guitarist for the band, but a fourth member to stay as a club. Yui is persuaded to join and they work to get her a guitar. For her starter guitar she decided on a Gibson Les Paul. After learning a few chords she is instantly amazing and can play songs that they never seem to have sheet music for. She can tune her guitar just by listening to it yet she takes bad care of it, she doesn't perform any mantinence on it for an entire year. She is also the lead singer for Hogaku Tea Time.
Mio is the bassist but since they can't have black people in anime they made her the one with big tits. you know, to make all the stereotypes happy. Mio plays a lefty 3 coloured Fender jazz bass. Since left handed instruments are less common then right handed instruments, Mio nearly comes when she sees a bunch of lefty guitars.. She is easily scared and embarassed which is why she chose bass over normal guitar. Despite that whenever Yui is unable to sing, Mio fills in for her. Mio is the songwriter and usually uses extremely girly lyrics. Her first song is called Fuwa Fuwa Time, which in English means Light and Fluffy Time. She originally wanted to join the literature club but the drummer/president/childhood friend Ritsu ripped her application and they formed the liight music club.
Mugi is the keyboardist for the light music club. She plays a Korg Triton Extreme 76-key keyboard. Mugi wanted to join the choir club, but joined the light music club to meet people she was not usually around. Mugi's family is really fucking rich. Her dad owns several villas, one being in Finland, and is a company president. She is embarassed whenever her dad leaves gifts at the villas for her. The music store that they frequently go to is owned by Mugi's father, where they call her Lady Tsumugi and give her amazing deals. Yui's guitar was originally 250,000 yen, about $2,500 and Mugi got them to sell it for $500. Mugi is blonde-haired, blue-eyed, (aryans, fuck yeah!) and has really thick eyebrows. Her eyebrows is how the music store clerk recognized her as the company president's daughter. In one episode where Yui has a fever, she dreams about Mugi's eyebrows. Since Mugi is rich, she tries to expirience more normal things. Like getting hit or working at a Japaneese somewhat McDonalds.
Ritsu is the drummer for Hogaku Tea Time. She plays a Rick Marotta Signature Yamaha Hipgig drum kit. She is energetic and upbeat and extremely forgetful. She neglects turning in important documents for the club. She was Mio's friend for a long time and constantly makes fun of her or tries to scare her. She is sarcastic and kind of a bitch. She's like our hero, is the point I'm trying to make. She plays the drum because she can't do the difficult finger movements required to play instruments like the guitar or keyboard. Her favorite drummer is Keith Moon from The Who.
Azusa is one year younger than everyone else in the light music club. She joined after hearing their performance at the freshman welcoming ceremony. She plays a Fender Mustang and has played since she was in the fourth grade. She secures the nickname Azunyan after the club's supervisor puts cat ears on her and makes her meow (although it never goes further into seeing if Sawako is a furry) "nyan" being the equivalent of "meow." Azusa looks like a character from an action anime with her red eyes and hair in weird pigtails.
