Many will hate me for this, but that's how I see it. Although at first glance when looking at the first 2 chapters (and some that come later) it seems that it will be interesting and that it has a lot of lore saved for later, the truth is that it does not exploit it at any time. When these important scenes are over, the worst of the worst begins. The series basically boils down to a serious scene, a battle scene, and then 3 or 4 filler chapters. Yes, I understand that the characters do not have their powers and more, but it is that these chapters in between have an extremely generic and repetitive humor (removing certain exceptions that do give some grace), and some of the most filler things i have ever seen, and it is that in the end it simply feels that they put these action chapters very by force, if it weren't for these specific chapters I wouldn't realize that I'm watching an anime that is about demons and that kind of thing. And the series "ends" very openly, with a lot of unresolved doubts. Yes, I know they are going to do a second season, but that is not an excuse for all the other flaws. For the moment, this will be the score that it will have until it improves with time (if im not very lazy to watch it again...).
