It's a great series with a unique premise but I feel there's a lot of untapped potential by the end of it.
Asides from being a unique point for drama, the dichotomy between humans and youkai could be explored in a more fulfilling way.
Characters are introduced and forgotten quickly in this series and the whole thing comes off as a unique pretense for a typical romance story.
The story falls somewhere between modern fantasy and romance, without fully committing to either. I feel like it was made simply because monster girl series have been popular lately and while it tries to add something new to the growing
genre it doesn't go far enough.
