Immoral

When a hypnotic spray that strips away inhibitions falls into a school doctor's hands, he immediately decides to use it on female students. That's the setup, and the show doesn't pretend to be anything other than what it is — a dark, exploitative 2-episode OVA from 2005 that leans fully into manipulation and control as its central theme. The doctor works his way through the school, using the spray to put girls in compromising situations one by one. There's no redemption arc being set up, no moral counterweight introduced early on. The tone is consistently dark throughout, and the power imbalance between the doctor and his victims is the entire engine of the story. If you're coming in expecting plot complexity, this isn't that. What it does deliver is exactly the kind of straightforward, unapologetic dark fantasy that a specific audience is looking for. Based on a visual novel and produced by Himajin Planning, it has that mid-2000s OVA feel — compact, direct, no filler. If you've watched Immoral Sisters or gone through something like Immorality and wanted more of that same dark school-setting energy, this sits comfortably in that same space. If Immoral Guild's lighter tone was too tame for what you were after, this is considerably further down the darker end of that spectrum. Two episodes, no long commitment required.
