Kaiji

Aired 2007

After one of his coworkers fails to repay a debt, apathetic bum Kaiji Itou is pressured by loan sharks to settle the large sum of cash. Since Kaiji has little money and no future prospects of his own, he is unable to return what his colleague borrowed. Faced with massive financial burdens, Kaiji is given an offer to board the illustrious Espoir—it is said that "one night aboard the ship, and all of your debts will be paid." What seems like a simple night of gambling quickly turns into a game of strategy and betrayal. With the losers of the tournament being subjected to a backbreaking life of indebted servitude, Kaiji must choose his actions—and allies—carefully. However, this is only the beginning of a series of gambles that will wager Kaiji's life, testing the full extent of his wits and will to survive.

Aired 2011

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, Hyodo’s company, the Teiai Corporation, is actively searching for Kaiji, and have sent Kaiji’s old “friend” 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 Endoh’s 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 “happy” to see one another, and both want to see Kaiji’s debt repaid, their means to that goal couldn’t be more different. Instead of leading Kaiji to the big score, Endoh delivers him drugged and docile to the Teiai Corporation’s secret underground labor camp where Kaiji will have an opportunity to repay his debt… with 15 years of hard labor.
