Quick take: Nothing breathtaking of note, but if you like occult, cryptids and the like, you'll find enjoyment in Mayonaka no Occult Koumuin. The story line is fairly straight forward and follows a new recruit in to the Nocturnal Relations Division of the police. Together with his co-workers and friends, he solves problems related to Anothers, or cryptids, which the average human cannot see. The overall theme of "understanding" is a little overplayed in media today, but if you don't mind that aspect, then you'll find the story line is very good. Art is really lackluster and is down right bad at times. Motions are mostly fluid,but at times the head or bodies of characters can seem slightly distorted when they move.

Sound is great in my opinion, with a jazzy BGM and good opening and closing songs. Acting (English) is well done and on par of most anime. The BGM errs by using some of the original scores' worse pieces and at some points can be distracting.

Characters are well developed and thought out. I do think there is a lack of use in the overall story though. In other words, Huehuecoyotl and Yuki are both funny and energetic characters that seem to be under utilized within the story line. In my opinion, it's just a missed opportunity.

Overall, if you enjoy the occult and cryptids, don't mind a bit of an overplayed theme and can look past the mediocre art, you'll find awesome BGM, great character interaction, good character development and an overall enjoyable piece of work, especially if you liked the main series.
