History Characters / KOn

** Questioning or commenting on her age will maker ''even more'' irritable.

* {{Catchphrase}}: In the dub -- "What are you, a grade schooler?"

** Contrast the above with the movie when Yui was clearly nervous about the restaurant manager. Yes, he's big, he's speaking English and he's backlit, but as seen above superficialities doesn't affect Yui. The story doesn't clarify whether he's good or bad, but this troper did notice he didn't pay the girls at all despite believing they were this band he had hired from another continent to play in his tiny establishment.

** In [=S2E6=], Azusa and Yui revisit the problem of octave tuning and warped guitar necks. This time, Azusa demonstrates the procedure. Yui picks up its essence instantly to the point of realizing what part of the procedure she can skip. One must wonder how many others could have done the same, though, since Azusa didn't define terms or explain what to listen for ... etc. Just pick, shorten string with finger at position 12, pick again. This troper confesses to running to the Internet to make the necessary connections, and he knew all three words.

* BunnyEarsLawyer: Outlandish as she is, Yui proves to be surprisingly clever and talented. Azusa's [[ChildProdigy years of experience with the guitar]] sets up Yui as this by contrast. For example, when Yui sees Azusa's electric guitar tuner, the audience learns that Yui doesn't know what a tuner is, but she has [[http://en.wikipedia.org/wiki/Absolute_pitch perfect pitch]], and can tune her guitar perfectly by ear. Of course, she has no idea what perfect pitch is. She's also not a great student most of the time [[BrilliantButLazy due to her laziness, but when she focuses on schoolwork hard enough, she can get excellent grades]].

** In university, Yui has found her new victim: Akira.

* TheDitz: A bit of an odd example. Yui isn't exactly ''stupid'' in the truest sense of the term, it's just that she's a {{cloudcuckoolander}} and very unfocused most of the time. That said, she does possess a fair amount of intelligence and creativity, and can be very competent and talented when the situation calls for it.

* GeniusDitz: Arguably this or a BunnyEarsLawyer, as she isn't outright stupid. Azusa's [[ChildProdigy years of experience with the guitar]] sets up Yui as this by contrast. For example, when Yui sees Azusa's electronic guitar tuner, the audience learns that Yui doesn't know what a tuner is, but she has [[http://en.wikipedia.org/wiki/Absolute_pitch perfect pitch]], and can tune her guitar perfectly by ear. Of course, she has no idea what perfect pitch is. She's also not a great student most of the time, but when she focuses on schoolwork hard enough, she can get excellent grades.

* InstantExpert: KyotoAnimation heavily averts from this for their [[AdaptationExpansion rendition of Ui]], especially in the second season. Instead of just having her figure guitar (and music) out by "playing a few times" or even "multiple" times, on the 5th episode they revealed she played the organ when little. In addition to learning the instrument itself, this exposure to music gives Ui a chance to have learnt how to read sheet music, acquire ear-copying skills [[note]]b/c '''Fuwa Fuwa Time''' in-show has only a lead sheet without a fully worked out score, for Ui to mimic Yui, she must listen to how '''Yui''' renders her part[[/note]] and perhaps even some music theory. This change makes her perhaps the second most veteran in music after Mugi, albeit with a very long blank that drops her present skill level with the organ to passable.

* InstantExpert: A minor case; it is revealed in season 1 episode 12 that [[spoiler:she taught Yui how to read guitar sheets, which is also how she's able to play Giita when posing as Yui]]. And again in season 2 episode 5, where she overhears some tips for hitting a baseball... and hits a home run immediately after. {{Lampshaded}} by Jun and Azusa.

* TheAce: Which causes Nao to search for her weak spot. In fact, she somehow managed to play a song written by Nao that Sawako says you can only play if you have 3 hands!

* NobodyLovesTheBassist: At first, Mio believes this to be true, since she has anxiety issues and is content with being in the background. Unfortunately for her, [[InvertedTrope this backfires spectacularly]] (see MsFanservice above) and she becomes the FaceOfTheBand. %%in-universe%%

* ShrinkingViolet: Shy around strangers and suffers crippling anxiety over performing in front of crowds. Decided to play bass so that she won't attract much attention, which backfires spectacularly when she becomes the FaceOfTheBand. %%in-universe%%.

* FaceOfTheBand: Most triumphant in-universe example... much to her dismay.

** In the same episode, she bores Yui to sleep teaching her to navigate the score. OK, maybe that's as much Yui's problem as Azusa's, but from a pedagogical viewpoint, Azusa should not have resisted Yui's efforts to make her connections with the new vocabulary. Playing is the best way to learn.
** But moving into IdiotBall level was with Nao in the ''High School!'' manga who was trying to demonstrate how you can build the C-Major 7 chord (C-E-G-B) on first principles of music theory, but gets stuck trying to "add" the B note. The joke is that [=CM7=] requires only TWO fingers, X-3-2-O-O-O: shorten the A-string by three semitones / frets for the C, the D string two semitones for the E, the next strings are G and B in their open state (they don't have to be ''added''), and it's OK to leave the high-E ringing as well; finally stroke while avoiding the low-E string. Clearly neither Azusa, Nao or Sawako-sensei realized this and only a last minute intervention moved Nao into digital music composing rather than leaving the club.

* AntiMentor: Azusa is quite the guitar player, most likely trained by her Jazz Musician parents and probably the most down-to-earth member of the Light Music Club. She can teach Yui and dispense tips to the 1st graders at Jazz Club. But she's less successful when teaching total noobs to play guitar. Cases in point:
** When Ritsu wants to learn to play the guitar, Azusa tries to teach Ritsu to play "Fuwa Fuwa Time", by showing her the (surprisingly accurate) musical notation for the '''vocal''' part, rather than starting with something simpler, such as correct posture and maybe a simple riff, such as the intro to "Fude Pen, Ball Pen". This is despite the fact that Ritsu, being a drummer, has never had the need to be able to read musical notation in the past, but Azusa just assumes that Ritsu can read it perfectly. Understandably, Ritsu gives up within minutes.
*** That's a "lead (a.k.a. fake) sheet" with only the melody, chords and lyrics. Textbook teaching for modern guitar says you teach the chords first, so Azusa started off with the E-chord and even adjusted Ritsu's left-hand fingers for her. You can argue she can be creative and go for something melodic employing only one or two strings, but the failure to do so isn't quite "idiotic".
** When Mugi tries playing the guitar, Azusa somehow decides that it's a good idea to teach Mugi, who is a total beginner at guitar, how to play Barre Chords, something which many guitar players spend months or even years mastering. And that's the first time Mugi even touches a guitar. No surprise, Mugi also gives up on learning to play guitar.
*** The last is not true in the manga, where Mugi continues to learn the guitar. Though we can call that an alternate Idiot Ball because to a contest winning level pianist, finger sensitivity is life and the calluses from learning guitar won't help.
*** Azusa was '''moving up''' to the F-Major Chord after some easier chords, and learning it is an essential skill. What's not essential is to immediately learn the Full-Barre version shown in the anime - there are 10 different ways to play a F Major chord on guitar, of which one, X-X-3-2-1-X does not require '''any''' finger to press on more than one string.
*** To be fair to Azusa, everything but the full barre version requires some strings to not ring (that X), so the player must be careful to avoid those strings when picking.
*** Yui is shown to have some penchant for barre chords, perhaps because they have a fuller ring and the same fingering can be moved up and down the neck for other chords, which means fewer fingerings to memorize.
*** Mugi is unusually strong so Azusa may have reasoned she can do it.
*** It's still a significant fail to not have alternatives on hand after Mugi is clearly struggling, though.
** Perhaps her worst fail was with Nao in the ''High School!'' manga. Nao was trying to demonstrate how you can build the C-Major 7 chord (C-E-G-B) on first principles of music theories, but gets stuck trying to :"add" the B note. The joke is that [=CM7=] requires only TWO fingers, X-3-2-O-O-O: shorten the A-string by three semitones / frets for the C, the D string two semitones for the E, the next strings are ''automatically G and B'' (they don't have to be ''added''), and it's OK to leave the high-E ringing as well; finally stroke while avoiding the low-E string. Clearly neither Azusa, Nao or Sawako-sensei realized this and only a last minute intervention moved Nao into digital music composing rather than leaving the club.

* [[AbsurdlyPowerfulStudentCouncil Absurdly Powerful Club]]: Consider the size of each music-related club's fiefs. Chorus and Wind Ensemble clubs, despite their numbers and prestige value to the school, '''share''' the Secondary music room ([=S2E17=]). Jazz Club, being numerically comparable to Wind, gets a classroom ([=S1E8=], [=S2E5=]). Meanwhile, Light Music Club despite having only 4-5 people usually resides in the Preparation Room, but also has the storeroom ([=S2E2=]) and officially ([=S1E1=]) the Primary Music Room which they use as they please ([=S2E7=]). [[spoiler:One can understand Chorus and WInd's reluctance to do them any more favors.]]

* SenpaiKohai: To the first generation.

* SenpaiKohai: She's a year older than Yui, Ritsu, Mio and Mugi.

** Unexpectedly, she definitely has her moments where she tends to be the one who thinks about practical matters: e.g., how much their training trip will cost (ep 4), or whether they're actually allowed to use the club room as they please (ep 5). She's also the first one to recognize Sawako (ep 5).

*** Sadly, it actually did - if you watch the episode carefully, you'd see again she lost her memories of playing the guitar, so she just air-guitared and sang during the song while Azusa played the guitar.

* {{Tsundere}}: Has shades of a Type B towards Ritsu. She's usually one of the nicest characters, but Ritsu's antics are enough to rile her up.

* {{Tsundere}}: She usually tries to shrug off Yui's acts of affection, but she always lets up in the end. This aspect of her personality is toned down in the anime.

* {{Tsundere}}: This seems to be the characteristic that Yui finds attractive in both Azusa and Akira. Akira even has ExpressiveHair that spikes up when she's ''tsun-tsun'' and lays flat when she's ''dere-dere''. It's spiky most of the time, of course.

* {{Tsundere}}: Slightly, towards Yukari. Apart from snarking at her a lot, Maho gets embarrassed thinking about telling Yukari about the fact she’s really impressed by her spirit.

* BunnyEarsLawyer: The only ones who likely get any consistent practice are Mio, Mugi, and Azusa. Additionally, most of their time together is spent enjoying tea and cake and [[NotSoAboveItAll neither Azusa nor Mio are above it all]]. Despite all this, they're actually really good when they perform.

* MischiefFace: When Ritsu Tainaka hears that the Light Music Club is to be disbanded, she grabs Mio's shoulder from behind and has a scheming look on her face while suggesting that if there are no holdover club members, she can easily take the role of Club President for herself.

* BigEater: She never gets fat for it, much to the dismay and envy of Mio and Mugi. In the song Ichigo Parfait ga Tomaranai, she likens herself to a black hole when it comes to sweets.

* ReluctantFanserviceGirl: In the manga, when Sawako has Yui dress up in a SexySantaDress as punishment, Yui acts embarrassed as she shows it off. It (doesn't) help that the dress is a two-piece.

* SweetTooth: The ''other'' solution to all of life's problems... except getting fat in the case of [[WeightWoe Mio and Mugi]].
