Sakai (堺市) is a repeater of the Restricted Rock, Paper, Scissors gamble on the Espoir.

Like Joji, he tricks newcomers into becoming his accomplices to later back stab them for money.


Tobaku Mokushiroku Kaiji

In order to pay his debt off, he convinces Ishida to go to the cell room to help him win extra stars.

When Ishida is sent the cell room, he makes signs hitting the glass wall to tell Sakai the cards his opponent have. Ishida is convinced that Sakai will free him from the other room, but it turns out that Sakai only used him as a pawn just to pay his debt and leave the ship with a lot of money.

He is last seen upstairs in the Espoir drinking.
