Akira and his friends are up against their toughest foe yet—Sae Nijima. Her palace is a rigged casino where they must outcheat the cheater every step of the way. Their final challenge before reaching Sae is collecting 100,000 coins from the casino. The quickest way to achieve this is a battle arena—but of course, nothing is ever easy. Can Joker face off against a gauntlet of foes alone so they can reach Sae and her treasure, and change her heart?
