It was an interesting story. I think it had a few bugs and left a lot of issues open. Of course, 99% of the anime I saw have a good story, but in the final part, the creators don't have a good idea and add things to the story that are not important and leave a lot of ambiguity. This anime also had a lot of bugs and I was expecting a better ending considering that the manga has been printed considering the time gap between the anime and the end of the manga, it means that a new episode will never be made, with a 99.9% probability, and this is a sad moment with ambiguity. be over forever
