When Kaiji gets onto the ship, he finds himself with hundreds of people who also have debt. The gambling event that will be played by Kaiji and the rest of the debtors, onboard the Espoir, is a game called "Restricted Rock Paper Scissors". It is known to everybody that those who lose in this gamble are forced into manual labor for years. After the explanation, Kaiji is then approached by a man named Funai. He gets Kaiji to team up with him; Kaiji doesn’t know what he just got himself into.
