* ActorAllusion: In episode 10 of season 1, [[Creator/YokoHikasa Shino]] is shown [[http://lurei.files.wordpress.com/2010/09/syd-e10-01-shino-or-mio.jpg cowering in fear and covering her ears]] in the way [[Manga/KOn Mio did]]. Bonus points, considering it was the exact situation (i.e., Tsuda recalls how he injured his finger with a broken plate).
-->'''Shino:''' D-Don't! I can't stand painful stories!
* FanNickname: {{Chinese|language}} viewers call this series ''Student Council of [[VulgarHumour Dirty Jokes]]''.

** Creator/YokoHikasa and Creator/SatomiSato play [[Manga/KOn another set of classmates with opposite personalities]].
** Creator/SayuriYahagi plays Suzu Hagimura.
** Creator/SatomiArai plays Ranko Hata.

** Hey guys, it's [[LightNovel/HaruhiSuzumiya Tani]][[MinoruShiraishi guchi]] with blue spiky hair and glasses!
** Mutsumi's seiyuu is ChiakiOmigawa, the very distinctive voice of [[Manga/SoulEater Maka Albarn]], SoredemoMachiWaMawatteiru.
** ''NyanKoi'''s [[ShintaroAsanuma Junpei Kosaka]] and [[YuuKobayashi Nagi Ichinose]] get to keep their roles!
*** Takatoshi's voice is also [[VisualNovel/DaCapoII Sakurai Yoshiyuki]]'s.

** Kaede Igarashi is played by Creator/EmiriKatou.

Watch Takatoshi drag Shino all the way back to ''Manga/SeitokaiYakuindomo'' before she puts her mind into the gutter.
