In the archipelagic nation of Cremona, there is a killer that has been eluding the police for a long time: Killer B. Truth be told, he's not THAT high up the priority list because he only kills other killers. Still, veteran detecive Keith thinks that it's much too dangerous to leave someone like that free, since he could start killing innocents at any time. Aided (not by his choice) but spunky but clever Lily, he tries to tack down this mysterious killer. Little does he know he's about to stumble into a plot about cloning, super-humans, an ancient race, and will have to come to terms with the brutal killing of his sister. A Netfilx original, for REAL this time. That tried to be more then it should have been. It had great animation, but the two stories (hard boiled detective story and sci-fy mutant action) did not mesh very well. Honestly, I enjoyed the detective part way more. The characters make the show. Keith is basically Sherlock Holmes, but more bitter (so basically Cumberbatch Holmes), while Lily was my favorite boll of spunk. While the main character IS Kokuu (the winged boy), he's kind of boring. Still, I enjoyed the show and it DID get renewed for a second season. Subs by Netflix, duh. Contains both 5.1 and 2.0 audio.
