The CGI animation looks fine; it is not so bad that it's unbearable to watch, nor is it so good that it should be praised. In some scenes, however, the animation is not that great, but it's easy to overlook that. The action scenes have some pretty good animation that deserves praise though. The character designs look good and the characters themselves are memorable (in the first episode, something weird happens, but apart from that, as the story progresses, the characters seem normal). The soundtracks are good, although they are usually very subtle. It is not anything memorable, but it's not bad either. I went intothis anime by only watching the 30-second PV and nothing else. I just now (while I am writing this review) read the synopsis on MAL and that seems like a minor spoiler, so it's better that you don't read the synopsis on MAL for this anime. Initially, I wasn't really into the story, but after watching a few episodes, I am genuinely interested to know what happens next.
