* CrossesTheLineTwice:
** Yayoi, wanting to educate your little sister [[TheTalk about sex]] is commendable. Attempting to do so via ''live demonstrations'' is sick and illegal, and [[HilarityEnsues also hilarious]].
** Kanna's friends and co-workers attempt to convince Motoki that women like it when you force yourself on them. They are all girls by the way. Even better, not only is Kanna in the room, but she does not particularly disagree, which makes you wonder about her... personal preferences.
** Sakanami, pretty much anytime he opens his mouth.
* {{Moe}}: Besides being a major SubGenre of eroge and therefore pertinent to Kanna's education as a seiyuu, different characters are clearly intended to appeal to certain moe archetypes.
* SoOkayItsAverage: The OVA is somewhat amusing and has some cute moments, but none of the characters get a lot of development and the plot is very simplistic, which means it probably won't leave a lasting impression on the viewer. People who expect a raunchy sex comedy will also be disappointed by the sheer amount of censorship it has.
* ThisIsYourPremiseOnDrugs: This is basically ''REC'' on crack.
