The world has fallen into ruin due to an invasion of spirits, ghouls, and monsters from another realm. The chances of survival were already slim for any individual on their own. But for a man with a gap in his memories, the odds were completely stacked against him. All he had to help him on his way was an ID card gracing him with the name Joker. A selection of strange cards that would always return to his pocket or hand regardless of where he left them. And a care taker that obviously new more about him than she let on. Dressed only in a jester's outfit with knives and daggers at her disposal that she could pull out of thin air like a magician. Will the questions of a man lost in a world already in ruin be answered? Or will he make a choice that puts him at odds with the rest of humanity? There is only one choice to make.
