The first half was some of the best anime I’ve seen. Then it devolved into a by the numbers shonen complete with a magical school and “tests” with unnecessary action scenes. I was ultimately disappointed by it because the whole season didn’t live up to the amazingly high standard the first few episodes set. I still enjoyed it and would give it a solid recommendation but it gets worse as it goes on in my opinion. The first half where you are properly seeing the world through the eyes of someone ageless has that beautiful sadness I don’t think I’ve seen anywhere else.
