Rio: Rainbow Gate! - Season 1 Episode 3 Misery

Howard takes Rio to a supposedly haunted castle which used to feature a casino owned by a woman named Misery, with plans to refurbish it as part of the Howard Resort. During the stormy night, lightning strikes the castle, which frees the ghost of Misery, who goes to the Howard Casino and spreads bad luck. She attempts to try and win the casino in a game with Anya, but instead falls victim to her clumsiness and freaks out. Misery later attacks a chicken wing delivery van, and when employees El and Il Adams discover her, they are attacked too. The next night, Rio gets a call from fellow employee Rosa Canyon, who had been possessed by Misery's spirit. Upon returning to the castle, Rio finds Misery, who challenges her to a game for the Howard Resort, having already taken control of El and Il and kidnapped Howard. The game involves betting to see if the dice will land on an odd or even number, but Rio is troubled by Misery's illusions. However, they are dispelled when Misery eats a super-spicy chicken wing she got from a mysterious delivery girl, allowing Rio to win the game and free Rosa. As Rio chases after the delivery girl, she reveals herself as her childhood friend, Rina, who has also been recruited by Howard.
