Is this... an otome game? And wait, I'm just a background character?!
About
This is a land where humans and yokai live in harmony. To other nations, this country is an anomaly. Originally, yokai were recorded as creatures that hunt and devour humans. In fact, wild yokai in this land still attack people, and such incidents never cease in other countries. However, most of the yokai here possess high intelligence and have made coexistence with humans possible. Of course, the profession of 'Yokai Slayer' still exists. What makes this place truly unique is the belief that becoming the mate of a yokai brings great happiness. If you mate with a powerful yokai, not only are you safe from other monsters, but you gain stable financial support and the absolute devotion inherent to yokai nature: "Once loved, loved for a lifetime." That seems to be one of the main draws. Tonight, where will the light of love shine— --- This story, which begins with such an introduction, is not the Western-style otome game everyone loves.
