Gambling Apocalypse Kaiji

After Kaiji's showdown with Chairman Hyoudou at the Starside Hotel, he's forced into labour at an underground mine. With his meagre daily wage, he'll be working for decades to repay his debt unless he does something about his miserable situation.
Kaiji decides to wager his earnings in an underground dice game for a ticket to get out of the mine for a limited period of time. But even if he surfaces, he only has one chance to win it big: by challenging the unbeatable pachinko machine nicknamed "The Bog."

A direct sequel to Tobaku Datenroku Kaiji, picking up immediately after Part 3 ends. After his tremendous victory in 2-Player Mahjong against the villainous President, Muraoka Takashi, Kaiji is being driven home by Kazuya, the son of Chairman Hyoudou. However, in the car, Kazuya asks Kaiji if he would be interested in one more gamble that night, and Kaiji accepts. What surprises lie in store for our dear Kaiji, and what will the gamble be?!
