Several months after the events of the first season, Kaiji, with his appendages reattached and his debt now run up to 9.5 million yen, is still desperately seeking the elusive big score that will cancel all of his markers. Unbeknownst to him, Hyodoās company, the Teiai Corporation, is actively searching for Kaiji, and have sent Kaijiās old āfriendā Endoh, who entered him in the high stakes games in the past, to find him.
The two meet when Kaiji chances to walk in front of Endohās car at a stop light, and thinking that he has found the answer to his prayers, Kaiji gets in the car with him. While Kaiji and Endoh are āhappyā to see one another, and both want to see Kaijiās debt repaid, their means to that goal couldnāt be more different.
Instead of leading Kaiji to the big score, Endoh delivers him drugged and docile to the Teiai Corporationās secret underground labor camp where Kaiji will have an opportunity to repay his debtā¦ with 15 years of hard labor.
