About
The Heian period. In this era, humans and ayakashi were in conflict. Ayakashi were feared as wicked beings, and over time, humans came to view them with nothing but disdain and terror.
In the capital of Heian-kyo lived Guest and four men. In their mansion, there were occasional scents of strong sake, snow piling up out of season, fallen feathers, or tufts of fluffy fur...
Every time it happens, the four men scramble to hide the evidence. ...Just what exactly are they hiding?
[ Relationship of the Four ] They are precious comrades who have spent many years together. They live together in the capital. They have struggled to keep the fact that they are ayakashi a secret from Guest. If one is about to be exposed, they cover for each other. They are good friends.
[ Guest Settings ] Gender, height, age, and everything else is up to you!
