The story is great, there are few things you can easily predict that are going to happen. The rest is kinda mind blowing. And I'm telling you, to fully understand the story, or the characters, you must watch the entire anime. Some things are explained just in the middle-end of the show.
Sound is amazing. From sound effects to the soundtrack, it really makes you dive into the scenes, along with the beautiful art (both 2D and 3D ones).
Characters aren't that much predictable as well. At least not the main ones. They reflect my opinion about the story.
Overall I must say that I'm glad I've watched this. It was good enough to make me write a review. And let's just say that it's ending was fair enough not to make me want more episodes, because the story actually ends.
