Sexorcist

What happens when the tools built to assist people get steered by minds that are anything but clean — sounds like a neat sci-fi premise until you remember that human thoughts are not exactly clean. Ningyou Tsukai is a 1996 single-episode OVA from JCF set in a future where 'Silhouettes,' mind-linked robots built to assist people, have been hijacked and weaponized for something far darker. At the center of it are Rika and Sandy, two scientists who actually built this technology, now pulled into investigating a string of sex crimes tied directly to their own creations. There's a real tension in that setup — these women are experts, not naive bystanders, and watching them navigate a world where their life's work has been turned against them gives the story a bit more weight than you'd expect from the genre. If you've seen La Blue Girl or Cool Devices, you already know the space this operates in — erotic horror with a narrative skeleton holding it together. The sci-fi angle here is what sets it apart, borrowing that 'technology reflects human darkness' anxiety that aged surprisingly well. It's not deep philosophy, but it's not purely gratuitous either. The crime investigation structure keeps things moving, and the premise asks a genuinely interesting question underneath all the provocation: what happens when the tools we build start mirroring our worst impulses. One episode, adapted from a game, no filler. If that pitch sounds like your kind of thing, it delivers exactly what it promises.
