Yui will one day marry her guitar.People in real life have married objects before, after all. Or maybe, one day Yui's guitar will magically become human from being showered with so much Yui's love.
Jun is a vampire.Just look at her eye color...it is kind of reddish,isn't it?Or it might be a geass?
Yui is Tyler Durden.The other characters are merely figments of her imagination. This theory can be traced to here and here.
Mugi is Tyler DurdenThis would explain why she's always trying to get people to hit her.
Yui and Ui's parents are Secret Agents.It is the ONLY explanation for why they would be out of the country so often (i.e. all the time) and still getting paid enough to send money home to their children.
Following that Yui and Ui's parents are Secret Agents, Ui is an AndroidBuilt to take care of their only daughter in their absence.
The Anime and the Manga are Alternate UniversesAlright, this is a pretty minor WMG. Every adaption has a few minor differences in story telling and so on, but before you go "Oh, you could say THAT about any The Anime Of The Manga!"... how would you explain Satoshi, who only shows up in the anime, otherwise? That "added bonus" that Ritsu had in the Christmas episode? Speaking of which, considering how Ritsu is related to both of those things...
As an Alternative to the above WMG, the Anime is less focused on Yui's POVThe first Episode was based mainly on how Yui saw the world because we had to be introduced to the characters. Slowly, the camera started to pan away from Yui and to either everybody or Ritsu. Yui would probably not be the type to remember such an incident as the photos in the Christmas episode, and while she did know that Ritsu had a younger brother (she only reacted negatively to Ritsu not coming to the hotpot because of Satoshi, and did not ask about him) she simply didn't care because of them not sharing any classes or club time. This could also explain why Tsumugi's hinted "dark side" isn't shown in the anime - in one case only Mio and her butler gets to hear about it, and in another only Azusa seems to notice the Death Glare that she gives a music shop worker. Now whose point of vision is this? It might be somebody who stalks the band as a whole, not any of the individuals. Said stalker might be a journalist who also interviews them once in a while shortly after their graduation, and then writes down everything he/she hears. Because the journalist is only human, he/she might miss out a few things, or even he/she first drew the manga, and then upon continued research and remembering more, started on the anime.
Yui is Kyon's little sister.This is very, very obvious in the flashback scenes. Just look at her! On the bright side, at least now we know where Haruhi's friend got his name from.
All the band's girls are Vocaloids/Instrument Simulators of some sort.It would make some sense, if we think about it.
The events in the series are pre-recession.The after-school job that the girls get as traffic takers is ridiculously easy, and would be filled even before reaching the classified section. Mugi's the daughter of the president of a guitar company AND her family has a large villa over the beach, where even her family members need appointments to get in! Yui's parents seem to travel around the world... ALL THE TIME. Also, the girls spend tons of money during their after-school time just buying more food and doing other activities instead of actually practicing.
Yui is somehow related to Hayate Yagami.First thought on seeing her was, "Isn't that Hayate?" Not much meat to go on, but still.
Yui is actually Hayate from an AU where the Book of Darkness doesn't exist.In this universe, the Book of Darkness never existed, meaning that Vita, Signum, and the other knights don't either. This means that Nanoha and Fate were never forced to battle with them. As such, she never met the two. Also, in this universe, Hayate was mysteriously renamed Yui and had a sister. Also, Section 6 is now screwed due to the lack of a captain and powerful artillery support.
Azusa is Kooh from Pangya all grown up.Kooh finally gave up looking for her dad and got bored of being a... golfing pirate. Plus, the hair! The nekomimi!
The girls are all the girls from Lucky Star in a new reality.Just as Konata was once Haruhi Suzumiya before she destroyed reality and remade herself into a (somewhat) normal otaku girl, she eventually grew bored again and remade herself as Ritsu, Kagami as Mio, Tsukasa as Yui, Miyuki as Mugi, Kuroi as Sawako-sensei, and Yutaka as Azusa. Though she actually split Kagami's mind, giving Azusa the dere-dere and Mio the tsun-tsun.
Yui and Ui are twins.As You Know, Yui and Ui are actually pretty similar to each other, to the extent that Ui can easily pass for her sister just by letting her hair down. Due to how school years work in Japan, everybody born before the date in which a school year begins can enroll; whoever is born on or after that date has to wait for the next school year. Twins aren't born at the same time, there's a delay between the two births, which can sometimes last a couple of hours. Ergo: Yui is the eldest twin, born just before midnight; Ui is the youngest twin, born just after midnight. Owing to what has been explained above, Yui has been enrolled in school one year earlier than her sister, despite their age difference being at most a couple of hours.
The girls of K-ON! are the girls of Ichigo Mashimaro, a few years later.Miu is Ritsu, Chika is Mio, Ana is Mugi, and Matsuri is Yui.
The series is a metaphorical satire of the decadence of rock'n'roll.Cakes = drugs.
Summary: Yui=Subaru and Ui=Ginga.According to various WMGs here, the girls are expies from Magical Girl Lyrical Nanoha, and they look like twins despite not having the same age. So, the answer is obvious: Yui, the clumsy book-dumb who can do anything when she actually tries, is Subaru, while Yamato Nadeshiko Ui is Ginga. Since they're clones, they're basically twins with an age difference. And yes, Ui is the older sister — it's been officially decided by the Club President in episode 8.
Strike Witches is what happens when the opening theme is taken to its logical conclusion.If they cut their skirts by a couple centimeters, they could jump higher than they could before. So if they remove the skirt altogether...
K-On! is an alternate story of how Estonia's Urban Symphony was formed.Manga was released in 2007. Band formed 2007. Anime released in 2009. Band participated in the Eurovision of the same year. Check out the band too: Mio has a very convincing IRL equivalent◊.
K-On! takes place in the same universe as Sora No Woto.
Ritsu consistently "programs" Mio to be shy, in a jealous or selfish effort to keep her relatively friendless or dependent on Ritsu.Flashbacks suggest that her badgering of Mio began from the moment Ritsu first met her. She may be smarter (or more sinister) than she lets on.
The class trip to Kyoto takes place on the same days as the Konata's class trip! They just never crossed paths!
Mugi is only part Japanese.You Gotta Have Blue Hair is mostly averted in K-On, with the exception of blonde Mugi (blonde hair is, of course, pretty rare in Japan). In the first Beach Episode there's a brief shot of Mugi as a little kid with her parents on the wall of her beach house (the facial features are a bit too blurry to make out, but you can still make out her hair). So the hair isn't a dye job. Perhaps her dad studied in America or Europe and married a classmate. Or perhaps her mom is Finnish and studied in Japan (it might explain their apparent villas in Finland).
The girls are all in an alternate and ultimately happy universe!Just think about it. They're all happy, can easily get jobs, and have no problem with their lives. Hell, if they turned out to be all lesbians, they'd probably face no opposition! In fact, the possibility of them in the real world is Deconstructed by the Doujin Requiem 5 A Dream. It all makes sense!
The girls are a fantasy of Haruhi Suzumiya!Just...think about it. Haruhi said once to Kyon We can be idols...with instruments!. Since Kyon thinks that the idea sucks,Haruhi created the girls of K-ON! And that's why the girls are alike the characters of Haruhi Suzumiya. Forgive me for my english!
Sawako from Kimi ni Todoke is actually Mio in a parallel universe where she never met Ritsu.In a world where she never has a friend to help take away her shyness, she never gets in to music and ends up going to a different high school altogether.
Ui is older than Yui.According to the DVD box set, Yui's birthday is November 27, and Ui's is February 22. This would make Yui three months older than Ui, which is clearly impossible. Therefore... Ui is actually the eldest daughter, while Yui is the youngest, making Ui older than Yui by about nine months; thus, they should have been in the same class. However, because of their parents' prolonged absence, Ui was forced by her sense of responsibility to take care of her younger sister, and was held back a year in primary school as a consequence of not being able to focus on her schoolwork. Also, being young when their parents left them, they forgot who was the eldest, and they assumed Yui was the eldest because she was one year ahead of Ui in school. It makes sense, especially if you consider the two girls' behavior: Ui is almost the stereotypical older sister, taking care of her younger sister, while Yui is the younger sister lazing under her older sister's care.
Sawako's musical inspiration is Zakk Wylde.The Ozzy Osbourne music book, her Flying V guitar and metal style...it all adds up!
Yui displayed Obfuscating Stupidity at the wedding performance.All the members of Death Devil and HTT planned in advance to have Yui deliberately play the song badly in order to force Sawako to take the stage, which was what Norimi originally wanted.
Death Devil's bassist "Della" is Himeko Tachibana's older sister.They'd have to be separated in age by ten years, though. See here.
Sawako is a fan of Bubblegum Crisis.The B-side of Death Devil's "Love" single is called "GENOM". This is likely to be a Shout-Out to the fact that Yuu Asakawa, who plays Norimi and sings backing vocals on this album, previously played Priss in Bubblegum Crisis Tokyo 2040 but didn't do her own singing. Death Devil is a way cooler band than Sekiria, anyway.
Yui is a certifiable genius and her ditzy side is simply very masterful acting.We already know that Yui's got natural talent for learning, so it's not impossible that she's just all-around brilliant. She's got the motive, too- Ui does all her work, feeds her, and lets her do whatever she wants, she can practically get away with murder at school, the other club members will do lots of things for her (such as Azusa tuning her guitar), and when she DOES manage to do something, everyone is more impressed than they would be if she showed her brilliance all the time. It's not unheard of in real life for a smart kid to feign idiocy to such ends.
Aya Hirano will guest star on K-On!!."In fulfillment of the awesomeness!"
Tsumugi is an AndroidThink about it: She has freakish super strength, fascinated by the ordinary and mundane things and life, anyone in the Kotobuki Consortium knows about her, and never gets sick. She was probably commisioned to be built by the President out of grief after his real daughter died in childhood. The Company probably anticipated her completion when the real Tsumugi would have entered High School (and thus built her body as a High School girl), but programmed her as if she were still a 10 year old. She also needs annual maintenance in Finland.
Yui, upon graduating, leaves Afterschool Teatime. She then leaves for college and eventually becomes a respected scientist/roboticist. She marries and has a son. She names him...Shinji.Oh Crap, Gendo's wife and the lead guitarist from K-On! ARE THE SAME PERSON! No, this doesn't make any sense. At all. But it is hilarious to see what would happen if you mixed a Tastes Like Diabetes Slice OF Life anime from Kyo Ani with a deeply disturbing, super-Mind Screw anime from Gainax. And yet...it makes sense, in its own twisted way. Yui Ikari, from what little we know of her, is/was kind and caring, most likely the kind of person Yui Hirasawa would be when she grows up, if her SickeninglySweetheart parents are any indication. Plus, as it says on the character sheet for NGE, one of the Evangelion games states that Yui Ikari was the daughter of a SEELE member, but the canonicity of the game is debated. If it were true, though, this could possibly explain where Yui's parents are going for all their "vacations". Or not. Please don't flame me.
The girls' first two years of high school were either dull and boring, or depressing and traumatic.But the series can only show the happy moments of their high school careers, and none of the drama. Thus two years of high school were compressed into 14 very slow-paced episodes while in most anime this would only be enough screentime for one year. Itoshiki-sensei would agree.
The original four band members are the byproduct of Kyon's polygamy
Yui is truly in love with AzusaCome one, how much more obvious does it have to get? She is quite clumsy in showing her affection, though, fueled by her inexperience and ditziness. Azusa might realize something is up as well, which leads her weary responses during their sleepover at the school. Maybe Azusa thinks that Yui, as a sempai, should take the initiative.
"Utauyo Miracle" will be the final concert that will end the seriesAt the time of writing this WMG, there are six more episodes in the anime, and one more chapter in the manga to go. Obviously, the four seniors will graduate...and they will do so with a bang! A final concert in Class 3-2 (can't use the auditorium since it's being used for the ceremony) is a fitting way to end their time in High School.
Nozomu Itoshiki will be transfer to JWU.Hey it is called Wild Mass Guessing, right? As a result from his incredibly successful teaching methods, Ms. Chie
Ui is (or at least used to be) The Un Favourite.Yui's name is written with the kanji 唯 ("only"), implying that the Hirasawa parents did not want more than one child. Ui's name is written with the kanji 憂 ("grief" or "melancholy" - just like in 涼宮ハルヒの憂鬱 or Haruhi Suzumiya), which may be an indication of how the parents reacted to the birth of an unplanned second child. The reason why Yui is so lazy and immature is that their parents doted on her, while making Ui do the household chores. However, they managed to do this without outright abuse, which is why Ui became responsible and caring, rather than resentful and envious (the fact that Yui herself was very nice to her, as seen in the Christmas flashback, must have helped as well). They probably learned to accept and love their younger daughter eventually, after seeing that she had become an indispensable part of the family.
Yui is Sonsaku Hakufu from Ikki TousenGoei has, at last, found a new husband, and has decided to travel with him. So, she left her daughter Hakufu under the care of her Yamato Nadeshiko younger sister Chuubou, with an ultimatum: don't rip your clothes, don't damage the house, or you'll see hell when I come back! So, Hakufu gives up on fighting, and takes up guitar instead. Just like she managed to copy martial arts without knowing their names or the theory, she learns guitar without a clue about musical notation. And she tunes her guitar by ear, just because she didn't know about tuners. Perfect Genius Ditz as always! Overall, she hasn't changed much: she's still a Nice Girl, always cheerful and friendly to everyone. She has a one-track mind; her motto is "Don't think too much, just be yourself and have fun". She's still a Big Eater; and she doesn't mind wearing cosplay outfits◊. Since she's extremely Book Dumb, you might wonder how she got (and stayed) into a good school like that. Quite simple: her smart dragon wakes up from time to time, and answers the tests in her stead. Hence her surprise when she sees the resulting near-perfect grades! She couldn't forget about Ton-chan◊ though, so she named the tortoise like him.
The final episode will be a flash forward.To when the girls are adults.
Tsumugi is a Time Lady.It's right there in the theme! light rock". Plus, compare the first few seconds of "Breve História" to the first few seconds of "Fuwa Fuwa Time".
Alternatively, the band Azusa may form after the finale probably will parallel Restart.While Azusa will upgrade into being Pe Lu's counterpart, her previous position as Koba's counterpart will be filled by Ui, while Jun may become Pe Lanza's counterpart, and Thomas's counterpart might be very well a New Transfer Student.
Sawako is actually a future version of Yui sent back in time to stop some cataclysmic event.That's right, Sawako (future Yui) comes from a crapsack future where the only way to save humanity is to go back in time to prevent some key event from happening. With her knowledge of the past, Yui goes back with a fake teaching degree, back story, and name to meet her old self and use her to stop said event from happening. If you look at the few pictures of Yui's mother in the manga, she is almost completely identical to Sawako. Much like some women look like their mother if you compare photos of them at the same age.
Ui is a clone created by her parents' first phase.
Yui and Ui went to France and Italy when they were little kids.Their parents were pretty much out of the country for much of the series (at least as far as we can tell), so it wouldn't be a stretch of an imagination that the sisters went with their parents overseas as toddlers. Why else would Yui have a passport as a child if they're not gonna use it? Evidence to support this include Yui's love of food (and craving a Marinara Pasta during the Summer Music Festival), and Ui's Character Image song 'Oui! Ai Kotoba'. It's just too bad most Japanese schools prefer to teach English as the requisite foreign language instead of French.
Azusa will go to the same university as the other girls after she graduates.
What's the relationship between Mugi and Sumire?Sumire Saitou, one of the two first-year students who joins Azusa's Light Music Club in the restarted manga's high school storyline, says she lives at the Kotobuki household and calls Mugi "Tsumugi-ojousama". From this we can speculate, in order of increasing tenuousness:
The movie will be about their foreign trip.Come on, it would be dumb for them to have an entire episode about prepairing for a trip an yet they never go.
Okuda is Yui and Nodoka's granddaughter from the future.She's pretty much has Nodoka's looks mixed in with Yui's personality. Came back in time to save Azu-nyan to prevent the club from disbanding and falling into dispair. But her mission was jossed and rendered unnecessary since her mere presence caused Sumire to join the clubButterflyOfDoom.
Mugi is a Sexual Deviant with Magical Tea.This is just a crack theory, but I thought I'd share it. It's been shown that Mugi wants two things: to get hit, though it was played as her wanting the skinship she damn well deserves and that she doesn't like when people fight, so she offers them her magical tea and cake. And this all started in her childhood...
Yui and Ui went to the same middle school as Kagome Higurashi.Same uniform design. Of course, Inuyasha came out over a decade before K-On, so they couldn't possibly have been classmates with Kagome... (or did they?)
Mio is afraid of barnacles because......She heard the story of The Ugly Barnacle and was scarred for life.
After the last of the four or five finish college, the girls will become a professional band.First order of business? Teach Yui basic chords... again.
Side character Fumie Kimura is a twin or a triplet.The Namayake girl standing next to Fumie◊ in this picture◊ resembles her quite a bit. Another background girl, shown in this picture◊ looks like she could be related to both girls as well. Perhaps one of them is Fumie's twin sister or both of them are her sisters. Or Kyo Ani felt like being lazy with character designs when producing the episode. Since we don't know much about Fumie.... it could be true
Class 3-2 student Kimiko Makigami is only half JapaneseShe clearly has a darker◊ skin tone, at least compared to her classmates. Perhaps she is biracial. Some netizens have dubbed her the "foreign looking" girl in class 3-2.
Yui and Ui are part of a nefarious cloning experimentSpecifically, they are an experiment to recreate Sherlock and Mycroft Holmes. Their "parents" are actually handlers in charge of training them to follow in their male predecessors' steps. Ui is Sherlock (a balance of single-minded brilliance and functional skills) while Yui is Mycroft (maybe a bit more skilled when it comes to single-minded brilliance, but otherwise lethargic and less functional.) The experiment more or less failed however when, instead of discovering the joys of investigation/secretive operations, they discovered the joy of music. Shrinking Violet nature (as well as Homura's).
Sayaka Miki is Ritsu's cousin.Let's assume that in the Madoka-verse, turquoise hair is equivalent to Ritsu's light brown.
Mami Tomoe is Mugi's cousin.Both their mothers were Finnish sisters who attended the same Japanese university and fell in love with two certain Japanese men. The lingering racial stigma of being "hafus" made both girls quiet, isolated and lonely.
Sawako Yamanaka is the daughter of Takano MiyoSawako youthful age would place her being born around the early 1980's, which coincide with the events of Higurashi no Naku Koro ni. Both Sawako and Takano share the similar hair styles, facial features, beauty, and the occasional bout of insanity. Sawako glasses and dark hair, in contrast to Takano, can be explained as traits of her father, Tomitake Jirou. Both Sawa-chan and Miyo also share the same voice actress in the dub.
The ending songs of both seasons and the movie are those of the girls after making it big. This would explain why they are done as an actual music video and Mio is the lead singer because her voice is more mainstream compare to Yui'a and/or she overcame her shyness.
Yui and Ui had their personalities switched when they were too young to remember.Why else would the little sister be more mature?
Sawako is not right in the head.Because no one can be like Sawako and be mentally stable.
The first ending is a music video from the futureAs noted above, they appear older (though not significantly), and Mio seems confident. Presumably after being together for a few years, Mio is able to work through her anxiety through some means and is able to become the lead singer. Yui is happy to become the backup vocalist, and because of the change in voice types, their sound becomes much more mature than before (in the first opening and during the series).
Are Ritsu, Yui and Mio a Comic Trio?Ritsu is the self-claimed leader. Mio is obviously the complainer. Yui is the one who keeps things going, and is also the most easy to manipulate. Sawa-chan, Azusa and maybe Mugi could fill respectively similar roles too, although with different results... Or not.
Tsumugi is a descendant of the Engineer from Team Fortress 2If the official comics and other Team Fortress 2 lore are to be believed, Tsumugi has a lot in common with the Engineer. The Engineer had blond hair and blue eyes(There actually is a cosmetic item called the "Big Country" that is the Engineer's hair as it was before he shaved it off, and he is shown to have blue eyes in a couple of the comics.) as well as considerable upper body strength(Engineer can carry those big toolboxes his buildings are in, and Tsumugi is shown effortlessly carrying heavy band equipment). Also, the Golden Wrench could explain how the Kotobuki family became so wealthy.
The whole series is Yui's dreamYui, being in a huge hurry, gets hit by a car in the beginning of the first season, and then goes into a deep coma, in which she dreams about a happy-go-lucky life with lots of cool friends which are based on the cool girls she saw when she ran passed them (Mugi, Ritsu and Mio can clearly be seen in the first scenes). Notice that there is an odd gap between the street Yui is in and the school she eventually reaches. In reality, that school is even in a totally different town, but in Yui's dream it's nearby, as she might have thought that the school in Toyosato looked so cool (or maybe she even attended the elementary school next to it). It all does explain why everything goes so smoothly most of the time, and how Yui could learn to play the guitar at such a level so quickly—it's simply something she wished to be able to do in real life.
Azusa had a lonely childhoodIn (S2) episode 5 where the band had matching keychains that spell "keionbu" (to symbolize their friendship), Azusa hesitated to 'complete the word' with her own keychain that they gave her. This is probably because she's not used to having people consider her as a "friend". She had no close friends in the past, maybe because she had an arrogant personality (it's shown when she daydreamed about being the club president). The other kids disliked her and this led her to have low self-esteem and become more serious. It's why Azusa begged the other girls under tears to not graduate. She didn't want to lose her only friends and become lonely again.
Mio and Ritsu are in love with each other but don't know that the other one feels the same way.Mio is probably just too shy to say anything (even if it is Ritsu something like that would be hard for Mio to say). Ritsu probably hasn't figured out her own feelings yet (Ritsu would definitely say something once she figured it out).
Yui doesn't care if something is male, female, or an inanimate object as long as she thinks it's cuteThe two things she is most fond of are Gitah (a guitar that she seems to think of as male, cute and her boyfriend) and Azu-Nyan (a very cute girl), so her current love interests cover all three categories.
Yui is actually Lain Iwakura.After erasing herself from everybody's memory and realizing her true nature as the goddess of the Wired, Lain eventually decided she wanted to live like a normal girl again, only with a life full of happiness instead of the seriously depressing one she used to have. She then created a new world inside the Wired where she lived as a childish, optimistic high school girl who sang and played guitar in her school's light music club. Note how both have brown hair (okay, Lain's is darker than Yui's, but whatever), have similar hairclips, play the guitar◊, and have a knack for becoming geniuses at anything as long as they have the motivation to do so (guitar for Yui, computers for Lain).
