History TearJerker / KOn

** During their first training camp, the group listens to a tape recorded by the previous member of the light-music club. When it switches over to Side B, it plays a voice clip (later revealed to be from Sawako) that leaves Mio cowering in fear. Ritsu, as usual, continues to frighten her which results in Mio crawling away before and ends up in a TroubledFetalPosition and profusely crying. It's really saying something when even before Yui and Mugi point out, Ritsu realized she took it too far.

** Another case is when during the Christmas party at Yui's house, Sawako forces Yui to wear a SexySantaDress as punishment for bringing up her ex-boyfriend. However, [[InnocentFanserviceGirl Yui ends posing proudly in it]]. Naturally, she makes Mio wear it, right down with forcefully undressing her. Even worse, Nodoka shows up right when Sawako removes Mio's pants. Mio is then shown sobbing about how "no one will ever marry her now".

** Likewise, upon realizing she has to sing at the school festival due to Yui frying her voice, Mio outright passes out. The day of the festival isn't much better as on top of getting scared by Mugi in a ghost costume, upon seeing the stage outfits Sawako made for the band, she starts to ''hyperventilate''. And at the performance itself, she trips over a cable and ends up in a position that exposes her panties to the audience. Mio is then heard screaming in absolute horror. In the aftermath of it all, poor Mio is reduced to huddling in a corner out of embarrassment. Someone give this girl a hug!

* If you suffer from social anxiety, Mio comes off as painfully relatable.

* The end of episode 20 of the second season. The girls just sit under the windows of their club room late in the day after their ''last'' live, and acknowledge they will no longer be a band after they graduate. Any form of sadness that the second season held behind a dam underneath the cheery, cute, colorful exterior comes falling down. The impact of this scene loses weight when all four seniors later pass the entrance exams so they go to the same university together, but it's still dramatic.

** Add to this that, during that scene, the BGM is a slower instrumental version of U & I, something of a love song that they had just played as their final number.
