Adaptation Displacement: Not a lot of people know that this series is a remake of TAGRO's earlier similarly-titled series called 'Hentai Seiri Seminar', which was published in hentai magazine despite not being pornographic (or at least no more explicit that how the series usually is). Justified however, since it only ran for 5 chapters.
Crosses the Line Twice: Oh christ. The OAV went even further, including a 10 minute discussion on how to eat feces.
