well, the character design is awesome.
very cute heroine and good looking hero which match with the voice actor give an exception for this anime to be called as good one. the story is not bad, since they use a different race that may display some confusing parts in the first episode.the character background is not very clear that may give an extra time to understand their role a little bit slower. I like the way the creator brings the story match each other each episode. I don't like the less introduced background of each character.
