Kaiji: Ultimate Survivor S1
Kaiji Ito has serious issues. Not only is he a social misfit, but he’s also a deadbeat petty gambler. After he gets duped into co-signing a loan for his friend, he’s stuck owing the Yakuza millions! Things start looking up when he’s given the chance to win his life back by gambling with other “lucky” participants on a mysterious casino ship, but soon Kaiji and the other contestants will discover the depths of human depravity when there is nothing left to lose — except their lives.
