This Anime is really good, the main characters are misterious and there's a lot of wonder while seing the chapters. All is uncertain and there's always a "what's happening here?" feeling. The main idea is really complex. It have a nice plot twist and the story is enjoyable. It's not made for people searching a basic anime, said that, if you're looking for an anime to clear your mind, this isn't a good one for that, it's a bit complex and have a nice end. The annimation is really good, and the sound is nice, there's not too much to say about this, is agood anime for watching.
