aka “Hentai seminar”
Genre: Erotic comedy
Rating: 15 for what’s seen, 21 for what’s implied
Nanako enrolls in the same course as Komugi so she can get close to him, but is utterly unprepared for the Abnormal Physiology Seminar, where fetishes are graded and the homework is dubious in the extreme.
Rather than employing fanservice as such, this show is more of an exploration of fetishes. They range from the understandable to the bizarre to the shocking to the downright disgusting. The various students each have predelictions of their own, and poor innocent Nanako is often the victim of them.
There’s not much plot as such, but it is fun.
