Akira and his friends are up against their toughest foe yet-Sae Nijima. Her palace is a rigged casino where they must out-cheat 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?
