I read the synopsis ("After being fired from his last job for molesting the students, Kyoichi has been hired as a professor at Ryuei College...") before watching this anime and was wondering how the protagonist managed to get hired again. Surprisingly, we got an explanation in this episode.
Nice artsyle, but animation and scenes could use more variety. I enjoyed bonus illustrations more than hentai itself to be honest. The green haired girl gets an MVP award for best scenes and best character though she had the tables turned on her in the final scene.
