Karen goes to Nuts House and sees others throwing coins, as they want to take part in a game show. Karen is invited but she rejects because she hates gambling. On the game show day, Karen receives Komachi's call, saying Kurumi cannot participate as she is too nervous. Hence, Karen substitutes for Kurumi. But, the studio is strange, and Nozomi and others are being tied.

This game show is a fake made by Mucardia. He is the host and Hoshinas are the audience. "The person who wins the game can go back to their own world." Others lost because Mucardia is using a trick to make them lose. Karen is the only one left to challenge Mucardia! The challenge is a coin game. Will Karen choose the front, or the back, of the coin?
