A Time To Screw, 각음색, 刻音色(ときねいろ), 刻音色

You found yourself in an old house located deep within the snowy mountains. It appeared that you had been brought there with a head injury and could not recall any memories. The mistress was surrounded by books, pictures, and cameras, while the four maids seemed to know everything. Despite this, you couldn't remember anything. It seems like time has stopped in this house. As midnight approached, the big clock that had been silent for years suddenly rang thirteen times. Suddenly, a dark blue shadow emerged from the depths of the well and began wandering around. The maids' snivels echoed through the darkness. Was it ecstasy or something else?
