* The entire conversation about hentai censorship.
* At one point during the slurping noises training, Kanna starts absentmindedly sucking her finger in a rather suggestive manner... ''[[FailedASpotCheck in the school classroom]]'', in front of her friends. Made even funnier in animated form in the OVA by cutting out the establishing shots of Hadzuki and Kotori.
* Fumika and Kanna's seiyuu contest to see who can get [[TheStoic Motoki]] excited using only their voices. Fumika goes for the [[BeAWhoreToGetYourMan slutty approach]] and is shot down, while Kanna launches an all out {{moe}} attack. [[MemeticMutation It's]] [[NotSoAboveItAll super]] [[MemeticMutation effective]]!
* It happens again during Hadzuki's and Kotori's training, only they work together for added impact.
* In chapter 24, Kanna and Motoki are out in a hallway, having a moment, which gets [[MomentKiller completely ruined]] when Motoki turns around to find virtually ''[[DatePeepers the entire remaining cast]]'' peeking at them from across the stairway.
* Chapter 25. "Go ahead and be forceful, I say! Kanna-chan's a pushover!"
* Chapter 26: "It's doing ecchi with the butt."
* Hadzuki channelling a reverse Sakanami in chapter 31, [[https://static.tvtropes.org/pmwiki/pub/images/Koe-de-Oshigoto_c31_08_7506.jpg down to the pose.]]
* "BE STUPID!"
* [[SoundEffectBleep VAGI]][[ItMakesSenseInContext NA!!]]
* The ero game shown in the OVA, which starts with a {{Meido}} giving a blowjob, causing Kanna to FreakOut and it just gets worse (better?) from there.
