I believe this show was a waste of potential.
The idea is cool and different. In short, the story is basically about the daily life of Koito (a shrine maiden - 'miko') and Elda (the deity of the shrine).
The cool and different idea relies on Elda, which is an Elf and on top of that a recluse who is into Otaku-things.
The problem is that they didn´t explore much of that uniqueness, and in the end the anime might end up just being 'another one' you will add to your list. For example: If Elda wasn´t an Elf, it wouldn´t change much except for the psychological effect that instead of a human she´s an Elf - they ocassionaly and randomly talk about her past (Edo period etc) but it doesn´t add much. She being recluse is poorly explored as well - they just show she´s afraid of going out and of interaction with other people and that is basically it.
-------- OTHERS:
- The secondary / support characters are fine. Honorable mention to Yord which made things more interesting and enjoyable to watch. Ah! There is Koito´s imouto (Koyuzu); the cute reliable imouto ^~^
- The animation is good enough but where this anime shines most is its art, which is very pretty in my opinion.
- Catchy OP music. As expected every seiyu did an amazing job, but honorable mention to Yord and specially Elda´s seiyu.
CONCLUSION: An anime that had potential for more but its uniquness wasn´t fully explored, but it might have a few scenes here and then that you might enjoy, specially if you are looking for a chill / easy going anime.
