Death games + gambling fanatic + text (charms) + suspense + supernatural powers + no harem + mind-bending puzzles.
I'm a gambling-house agent, and today I encountered something strange!
I saw ghosts! And gods, too!
Here, you can become a false god and wield supreme authority and supernatural powers.
I was forced to come to a place people call the Heavenly Court. There, I awakened supernatural powers. People here can take part in death games through contests of wits and strength.
I was reborn, and yet not reborn. In this land of death, I dare not believe I'm human. I am more inclined to believe I'm a ghost, or perhaps a god!
