When I woke up, I found myself inside an iron grate. Hairi had been proposed to by his girlfriend a few hours earlier. On the way home, he seems to have been kidnapped by someone. I looked into the darkness and there was also his old girlfriend Kageji. Kageji has a debt of 17 million yen, and Hairi used to be the guarantor. He was kidnapped to pay off the debt. In order to participate in the gambling TV "Death Game" broadcast for a mysterious rich man... He says that if he can win the game of life and death, he will not only get rid of his debt but also get a lot of money. If you lose, you die, and if you don't do it, you'll be in debt and you'll be in hell. Can Hairi, who majors in psychology in graduate school, capture special gambling such as "Russian Roulette of Death", "Antarctic Yakyuken" and "Indian Poker"? The battle to the death between Kageji and Hairi begins!!
