Summary
High school student Ichiro Sato keeps finding himself in embarrassingly erotic predicaments with Kana Kojima, a young teacher who has a reputation of being a demon to her students. Later volumes introduce more male students paired with female teachers in similar circumstances.

Teachers

 * Kana Kojima (児嶋 加奈)
 * A high school Japanese language teacher at Kawanuma West (川沼西高校) who is nicknamed "Kojima the Demon" (鬼の児嶋) because of her combustible temper. But when she is close to Ichirō Satō, she is shy and clumsy, and they end up in a number of unseemly erotic situations. It is revealed that she is from the same home town as Sato's mother. As a high school student, she was shy and wore glasses, but was encouraged by Sato to become a teacher. Starting in volume 2, she and Sato are a couple. A bonus chapter in Volume 1 shows that she visits him often while he is in college. She and Ichiro later get engaged and are living together by Volume 6.

Reception
Anime News Network reviewers had mixed reviews about the anime show. James Beckett wrote, "This isn't a 'good' show, but God help me, I chuckled a little at just how unashamed it was." Lynzee Loveridge wrote that "it's edited porn airing on a Japanese satellite station." Nick Creamer wrote that the episode "definitely knows how to set up a sexually charged scene, and even has the production values to make its characters look genuinely attractive". Theron Martin wrote "If you find suppositories and someone holding in pee to be sexy then you might like this one, but it's definitely aimed only at a certain kind of kink."

Allen Moody of THEM Anime Reviews gave the anime show 1 out of 5 stars, noticing the "tiresomely repetitive fanservice formula in use" and heavy censoring that "None of this is really funny- as presented, it's not sexy either-" He found the groping scenes to be endlessly repetitive, and "along with all the related humiliation and embarrassment of the women here, that finally completely wore out my patience".
