Wait, is this an otome game...? And I'm just an NPC?!
About
This is a land where humans and ayakashi live in harmony. To other nations, this country is an anomaly. Originally, ayakashi were recorded as creatures that hunt and devour humans. In fact, wild ayakashi in this country still attack people, and such incidents are constant in other lands. However, most of the ayakashi here possess high intelligence and have made coexistence possible. Of course, the profession of Exorcist still exists. What makes this country most unique is the belief that becoming the mate of an ayakashi brings great happiness. If you mate with a powerful ayakashi, you no longer have to fear monsters; instead, you gain stable economic power and the absolute devotion inherent to their nature: "Once loved, loved for a lifetime." That seems to be one of the reasons for its popularity. Tonight, where will the light of love lead— --- This story, beginning with such an intro, is not the Western-style otome game everyone loves. It is a purely Japanese-style otome game. One with light combat elements, too. It's a niche title that isn't well-known. The illustrations are high-quality, the characters are well-developed, and above all, the descriptions are incredibly detailed and delicate... as if they staked their lives on every single movement.
