Rin

Rin is one of the strangest – and one of the most addictive – anime series to come along in years. It the story of an immortal detective and her 65-year investigation into a crime that almost defies description, particularly because of the way the chapters of the series weave the mystery together over the decades that the story takes place in. The mystery of why Rin is immortal, as well as the subplot of the vengeful forces who want to truly test whether she can die or not, is equally well told, although you almost need to make notes along the way and then go back to re-watch episodes to keep it all straight in your head. (The effort is worth it, though, once the light bulb goes off and you figure it all out.) A word of caution to potential viewers: Ren is definitely an adult anime series featuring some truly graphic – and haunting – images throughout. It’s not for the squeamish.
