Kurohime: Shikkoku no Yakata (also known as Black Widow) is a dark 2‑episode hentai OVA from 2002 that blends horror and bondage with a sinister, almost supernatural tone. A group of college‑age friends on an innocent camping trip stumbles into a mysterious mansion where they are hunted and tormented one by one by a mysterious black‑clad woman, descending from light‑hearted tension into scenes of uncensored domination, psychological dread, and twisted erotic horror.
