Holy Sleazy School

When a phallus-shaped, glowing artifact shows up at a Japanese school and drives the female students absolutely wild — that's the setup, and it goes exactly where you'd expect. A male teacher gets pulled into the chaos when a student makes her move on him, and he quickly discovers the artifact has left him with some kind of irresistible supernatural pull over the girls around him. What follows is a single OVA episode that leans fully into its absurd magical premise without apologizing for it. The supernatural angle is genuinely the hook here — it's not just a standard scenario, there's an actual artifact with actual powers at the center of everything, which gives it a slightly more interesting frame than most entries in the genre. If you've watched something like Bible Black and appreciated how a weird mystical premise can carry adult content beyond the usual setup, this scratches a similar itch in a much shorter runtime. Fans of Discipline or Night Shift Nurses who like their hentai wrapped in a school setting with some light genre flavoring will feel at home. It's a single episode from 2007 by Studio Jam, based on an original story, so there's no manga or game to cross-reference — what you see is what you get. Short, strange, and committed to its own ridiculous concept.
