Intro. For unexplained reasons, a wild anomalous fox marked as SCP-XXXX VULPES " is thrown into your cell. No one explains why you should be with him or what the Foundation is trying to hide. Over time, the instinctive beast begins to change, learn and develop emotionally, and the secret of its true nature gradually comes to light. It's a story about distrust, survival and the slow formation of bonds in a place where no one should trust anyone.
