Ijoku aka Medical Humiliation is the generic prescription of nursed themed hentais. Nurses abuse or get abused in a mundane attempt at pyschodrama. It involves BDSM, yuri, piss, some femdom, and rape (the type of rape where the victim starts to enjoy later on). If that sort of thing rocks your boat, then you may want to consider giving it a try. Otherwise, don't even bother.
Like most hentai series out there, Ijoku has a very weak storyline. It makes as much sense as a 3 year old trying to tell you a story: "Once upon a time a man appeared in a hospital who he
lost his memory. All the nurses liked him and decide to make him the janitor. He became really angry and hurt all the nurses to solve a mystery. Then there was a head nurse who liked hurting other nurses, so the janitor had to regulate. After he became the regulator, everyone lived happily ever after. The end." Which is to say it didn't make much sense at all. It was more of an attempt to glue together the ample amounts of ecchi scenes that makes up the bulk of the hentai.
I would say the only thing good about Ijoku is the character design. It does seem a bit simplistic, but looks good with pretty eyes and well proportioned bodies. The voicing was well done as well. The moaning and whining that goes on was rather erotic and pleasing to the ears. However, all this doesn't make up for the blandness of character. With a big cast of characters (seven nurses and one dude) in the span of a short 2-part series, none of the characters really develop any depth to empathize with. They just sort of appear, get abused, then disappear. Although there were some genuine attempts at some disturbing scenes, with no connection towards any of the characters, it made for an apathetic viewing experience, which defeats the purpose of rape and BDSM themes.
The animation was cheaply done. A slow pan of repetitive frames is about all you get in all the ecchi scenes. Seemingly about 90% of the hentai is ecchi scenes, the bulk of Ijoku is just about that: A slow pan of repetitive frames. Okay, I guess that's good for a wrist work out video. Being uncensored is also a bonus.
After the famed series "Night Shift Nurses" came out, a lot of hentai producers decided to cash in on the nurse theme. In this case, the creator of Ijoku completely missed out on what made "Night Shift Nurses" so... well, infamous. It was character development and empathy along with well choreographed sex scenes. Ijoku had none of that, which makes for a very bland hentai.
