It's great to know there's fans of Ogenki Clinic! It was one of the first anime I ever watched (yeah, I was pretty young.. lol). I loved it then and I still love it now. I think I especially loved episode 4, with the people who dressed up like superhero parodies, lol. I'd love to read the manga, Nurse Tatase looks amazing here.
I remember this series making my jaw drop with just how kinky and perverted it could be, as well as damned funny. I love the theme song from one of the series. Nice tribute to an early favorite of hentai.
