Debtor and one-time coworker of Kaiji. One year before the first tournament on Espoir, he lured Kaiji into cosigning a loan for him, making Kaiji liable in case Furuhata did not repay the loan. Although believed to have disappeared, Kaiji discovers him on Espoir and makes an alliance with him after Funai&#039;s betrayal. (source: wikipedia) 

Itou Kaiji is a bum who steals car emblems and slashes tires on what seems to be a regular basis. This routine changes one day when he is paid a visit by a man in a trench-coat. Once the two get talking, it seems that the visitor (Calling himself Endou) is a debt collector. The reason for his visit is an unpaid loan which Kaiji had previously co-signed for a work-mate (Furuhata Takeshi). The original loan was 300,000 yen and once Takeshi had disappeared, the loan then fell on Kaiji. 
Kaiji is then told of a way to clear the interest compounded debt (which stood at 3,850,000 yen), which involved getting on a boat with others in his position. Once on the boat the debtors would then have to gamble with loaned money, which would end with a few winning, and others getting into deeper debt and having to work to pay off their debts. After some coercion Kaiji accepts a position on the boat, in order to clear his debt and make a bit of money as well...
