James Blood wakes up chasing a ghost. The mask exists, the man wearing it shouldn't, and neither fact makes sense until you realize the show has been lying to you about which one matters. It's a crime procedural that keeps rewriting its own mystery, pulling you deeper into a conspiracy where every answer is a trap door to a bigger question. The animation is CGI and it shows. You either surrender to its strange, plastic rhythm or you don't, but if you do, the story becomes something closer to a psychological thriller than an action show. By the final episodes, you're not trying to solve the mystery anymore, you're trying to understand what the show actually was while you were watching it.

James Blood finds himself confronted by a mysterious Mask, and the man hidden behind it is someone who should not exist at all. Set in a beautiful city, the story is an action-heavy crime tale built around the puzzle of who the masked figure is and what secret surrounds the mask. The fifteen-episode ONA mixes action, mystery, science fiction and thriller elements.
