I will come out and say this. Seriously underrated work. Deserves at least an 8.5 rating. If you like crime solving and some philosophical theme this is of your taste. I usually skim through the videos and determine whether to watch an anime or not. I think after seeing this i would change my POV. Eventhough it is quite good it is not really the type of anime you want to watch again and again. But still for a single time it really is fun and we wont feel like we wasted our time watching this. So i recommend this anime to those who likecomplex plots and note here that the story progresses quite slowly despite only having 11 episodes.
