I think this Anime was really well done in terms of everything. Story, characters (especially magic powers) were very interesting and really made me feel amazed sejak it. It also has a mixture of many genres such as romance, comedy, slice of life while the main genre being fantasy.
This Anime also seems to menanggung, bear a resemblance to Sword Art Online as both involve the use of magic and the plot is somewhat similar. So if anda like SAO, you'll definitely Cinta this too! Tatsuya is just like Kirito and Miyuki is just like Asuna in some aspects.
