Black Holy Sword

The girl woke up from a strange place and lost her memory. She even knew nothing about herself. She even forgot her name. Facing this different world, it seems as if I have never been there before. I don't know how long I have been sleeping, and I don't know how much time has passed. All that is left behind is an empty shell of stone. Is this a second life? Or is this a punishment from God? Is it right or wrong to search for lost memories?
