 If you liked Dark Gathering |  ...then you might like Kaii to Otome to Kamikakushi |
Both shows are quite similar conceptually and aesthetically, being easily described as an urban detective fantasy based on Japanese urban legends and folklore. The main noticeable difference is that while both shows focus on young adults who discover that their friends have frightening knowledge and connections to the other world, Dark Gathering is more aimed at a teenage audience and a male POV, while Kaii to Otome is aimed at a more mature audience and tells the story from the perspective of a noticeably more older female lead.
