Kunoichi Ryoujokuden Ajisai

Capable of slipping into heavily guarded estates and vanishing without a trace, Ajisai — a kunoichi, a female ninja — has been tasked with investigating a string of disappearances targeting young women, and the trail leads her straight into the compound of a corrupt feudal lord running something far uglier than expected: drugs, trafficking, the whole operation. She gets close. Then one small mistake gets her caught. What happens after that is where the show goes in directions that earn its hentai label pretty quickly, so go in knowing that upfront. This is a 2-episode OVA from 2023, adapted from a game, and it leans into the classic trapped-kunoichi setup with genuine feudal Japan atmosphere — the espionage details, the underworld politics, the tension of a mission unraveling. If you've watched something like Kunoichi Hazukashii or similar ninja-themed adult OVAs and enjoyed the blend of action setup with explicit content, this fits comfortably in that space. The story itself is straightforward but gives Ajisai enough character that her situation actually carries some weight rather than feeling completely hollow. It's not trying to be Kunoichi Tsubaki — this is unambiguously adult content — but it uses the feudal setting well enough that the setup feels earned rather than just incidental. Two episodes, self-contained, exactly what it says on the label.
