The Case Files of Yakushiji Ryoko



Yakushiji Ryoko is a Superintendent in the Tokyo Metropolitan Police Department, and with her lackey/slave/chew toy Assistant Inspector Junichiro Izumida They Fight Crime, though more often than not the cases end up involving the paranormal. While being in the Metropolitan Police Department's Criminal Investigation Bureau, Ryoko is the daughter of JACES President Hiroko Yakushiji, who is a high-ranking ex-MPD officer. As such, she is the "official" Yakushiji known in the public to be standing ready to succeed her father. Think Law and Order meets The X-Files meets James Bond and you have a rough idea of what the show's like.

Notable for featuring an adult female protagonist above the age usually considered attractive who is still Badass and incredibly competent while also being extremely sexy.

Created by Doctor Yoshiki Tanaka, Ryōko Yakushiji's Strange Case Files (Japanese 薬師寺涼子の怪奇事件簿 - see the Trivia subpage for other translations of the franchise name) is a franchise that consists of a drama CD, an anime and manga series that has been concluded with 11 volumes alongside light novels.

As of 2019, the series was only legally available in Japan.


 * Adaptation Distillation: While the manga did take some aspects from the light novels as some of its stories were available with the former, there's no way that the anime did the same. But the production team did a bit of a good job with a reference to the Tokyo Nightmare novel.
