Star☆Jewel

In a futuristic Budapest, goddesses of light and darkness are at war, and the battlefield is other women's bodies. The dark side, led by General Zircon and her subordinates Lapis and Ruby, hunts down innocent women to steal their Star Jewels — life-force crystals that, once taken, leave their victims comatose. Standing against them are three goddesses of light, Natsumi, Mei, and Reiko, who blend into civilian life while tracking down the enemy before more victims pile up. The concept has genuine intrigue — a magical girl framework where the stakes feel immediate and the threat is visceral. Don't let the cosmic mythology fool you though; this is a one-episode OVA from 2011 with explicit adult content baked into its core premise, and it leans into that fully. The action and fantasy setup are window dressing for the hentai elements, which are central, not incidental. If you've seen something like Mahou Shoujo Ai or Bible Black, you already know the genre this sits in — adult content wrapped in a genre aesthetic, with more plot scaffolding than most entries bother to build. The Budapest setting adds an unusual flavor that separates it visually from the usual high school or fantasy backdrops. It's a single episode, so there's no long investment here. Go in knowing exactly what it is, and it delivers on its own terms.
