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 growinggenre it doesn't go far enough.
