When you wake up from amnesia, the rules are set.
Welcome to the ultimate game, participant Chen Mo.
Your memory is a blank first page, your health is beating on your watch. This endless gray-white maze is your entire world.
What you know is that you must use playing cards as keys to unlock extraordinary powers and fight against mechanical hunters. What you believe is that only by collecting five Aces can you win the atonement that leads to freedom.
But why have you come? Who are you? Are those bizarre memory fragments echoes of the past, or traps set by the game? Are those "companions" who fight side by side allies worthy of being entrusted, or opponents with ulterior motives?
In this card game where memory is used as a bargaining chip, do not trust the dealer and be wary of your dealer.
