Rin is a private investigator with an advantage: near immortality. Thanks to the spores of the Yggdrasill tree, both she and her assistant Mimi have lived many years longer than the average person. That isn’t to say that being immortal doesn't have its problems. With 'angels' wanting to devour them, the being Apos sending wave after wave of professional assassins to kill them, and constant hangovers from long nights of drinking, being immortal still has its downsides. With Apos' attempts at removing them from the picture increasing, can Rin and Mimi figure out what he is after so they can return to their morning shots of Vodka?

However, as Izumida quickly discovers, Ryoko's talent comes with a big ego and some strange personal baggage; cleaning up the streets of Tokyo becomes not just a matter of finding the bad guys, but trying to survive Ryoko's attitude problem as well!
I can't quite say exactly why Mnemosyne and Ryoko's Case File seem similar. Sure they both involve investigation, and there is the supernatural nature of both of them, but it goes beyond that.
It was while watching the later half of Ryoko's case files that I most felt the similarity, specifically regarding the type of plot and the overall story arc.
I'm fairly certain if you enjoyed one, you will probably enjoy the other.
As strong female characters in Mnemosyne and Ryoko’s Case File investigate bizarre and supernatural events they are also trying to find love along the way. While Mnemosyne involves more explicit content the stories are quite similar in attitude and feel.

Both of these series have dark atmosphere, female leads, a lot of gore and extraordinary females fighting against male monsters. Both also are quite sadistic. Almost every episode shows female character getting tortured.
