Of the chapters I read, Kagamigami left an impression of feeling like the author was attempting to enter into the crowded realm of the ghost elimination subgenre of action series. Unfortunately, the chapters offered little in the way of anything new nor displaying a refining of the concepts it was attempting to emulate. However, the lead male character had a great character design so he was one I could get behind, however the other characters were very lacking. The female character for example, could have been inspired from Bleach's Rukia in this genre that has little space for new entries. If he had done this then it could have been very good. Instead, making her a goofy aloof type made it feel odd and kind of backwards. This prevents her from being able to make substantial contributions to the plot which is unfortunate. This would essentially make her a tag along type which is not a very good character to have. I was hoping she could have been like Sakurako [hardcore version] from Psyren [except without the blatant romance that ruins her normal character as the series goes on], which really made that manga a definitive entry for its generation.
It would be the type of manga that I would read but not one I would buy digitally or physically. If the main cast grew by giving him a protege that looks up to him or someone who can also transform like him and is his age, then I think it would really make this a must read series. Also make ghosts and whatnot designs more equivalent to PKMN or Yokai Watch.
