Mint Clark goes on holiday with her grandfather to the Howard Resort. While her grandfather enjoys the casino, Mint explores the resort and eventually meets the casino's most famous dealer, Rio Rollins Tachibana. As Rio and Mint go for a walk, they are approached by a man and his henchmen who attempt to take Mint's teddy bear, Choco, but Rio fights them off. After Mint bears witness to the good fortune that Rio brings to her customers in the casino, they are once again approached by the man, Orlin Dunhill, who decides to play a game of closed poker against Rio for Mint's bear. Orlin makes a gamble to get four Queens though, but thanks to Rio's ability to communicate with her cards, he loses out to Rio who wins with a pair of twos. Afterward, Orlin explains he had been collecting rare stuffed animals to fulfill his sorrow from being dumped at the altar, only to then find that Mint's bear isn't a Belgium original.
