New science teacher, Machiko Mai, is a young and attractive woman with healthy mind and body. Being around her makes everyone happy. Students like to play practical jokes on her, but no matter how many times they cause troubles, she does not get upset. She always tries hard to understand her students.Maicchingu Machiko Sensei is a series that could be best described as a loose compilation of Fanservice or Ecchi, starring a female schoolteacher and her pervy students. It aired in The Eighties in Japan as a kids' show. It had a lot of controversy with the Moral Guardians but somehow managed to survive.Machiko Mai, a young and inexperienced teacher, is taking her first job as a teacher to a group of elementary students. Unfortunately (for her), Machiko's students, lead by resident troublemaker Kenta, think it's utterly hilarious to grope her, flip her skirt, or find new and exciting ways to get rid of her clothing. Even worse, the very universe itself seems to think it's funny too; despite her best efforts, almost every adventure ends up with her at least slightly humiliated (ie: stripped to her bare pantsu if not completely naked).Add a cast of ninnies and perverts, a standard children's show plot, and you have one of the most infamous ecchi series in history.It is finally getting an English release, 30 years after the manga started, courtesy of Anime-RG.
