Life is but a mystery itself and mystery shows merely cover a portion of it. MLR (Matantei Loki Ragnarok) is a example of such a work. Using Norse Mythology as it's background, it tries to mix supernatural events with mystery. The story isn't the most amazing thing you'll come across, but it's still good. Characters aren't the most amazing, the female MC is very generic, often found in many other mystery works, such as Spiral (Which i think is a little better than this). I like this a little more than most people, most likely anyways, because i love the whole premise of mythologyitself, whether it be Greek or Norse. The idea of an entire world of gods existing is very fresh and interesting to me. If you are interested in Norse mythology, watch this. You most likely won't learn too many new things but it will most likely be interesting.
