Full Dimensional Game

Our protagonist is a tragic figure whose past memories have been sealed away. It's an existence that doesn't even know its own name. Being thrown into a huge game like a puppet by an unknown being. What's even more terrifying is that the game scenes are all played out in real environments. What should he do? What shocked him even more was that this was a game that spanned time, space and latitude. This novel and its characters are purely fictitious.
