When I came to, I was standing somewhere in the wilderness where the snow was falling. I don’t know why I’m in a place like this Rather, my memory… I can’t remember what kind of person I am, or even my name. I stood still, shocked at the situation. But, as if to ridicule me, a giant bug-like “monster” suddenly attacked. I was cornered as I desperately tried to escape. I was in an extremely dangerous situation. But then a girl gallantly appeared. Her name was Kuon, and this beautiful girl with animal-like ears and a tail, saved my life.
