One of the most beautiful, contemplative, and informative anime of the season. At first, I had some prejudice about watching this anime. I thought, “Why would I want to see cute, busty girls studying rocks?” And I was completely wrong, because the anime is so much deeper than that — and of course, I also watched it because of Nagi. This anime was so good it actually made me want to go out looking for rocks, figuring out where they came from and everything, that’s how contagious it was. If only I had a Nagi-san in my life, I’d sleep so peacefully.
