A sweet anime with nice art, good voice acting and an interesting premise. That being said I feel this show is a bit overrated. The story doesn't really go anywhere, the antagonist turns out to be somewhat boring, and the main character is going to die if she keeps using magic. Of course she keeps using magic and always gets gravely sick/injured but she always turns out ok so it doesn't matter and she keeps doing that in almost every episode. The emotions are somewhat shallow despite what some people have been saying. It almost feels like a children's show at times. The character development is there but it was hard to get invested for me. I had a hard time keeping myself engaged with the show and had to take a break a couple times from the 24 episodes to watch more entertaining animes with better writting and deeper emotions. In the end i couldn't wait for the last episode to end so I use my time to watch something better. A fairly boring anime with a boring ending.
It might sound like i didn't like the show but it really wasn't all bad. i just wanted to tell you the cons that are not included in the other reviews. If you have time and you're looking for something new and different to watch this wouldn't be a bad choice but I wouldn't say this is one of the best animes like some people are saying.
