This is a casino where people can play cards, dice, slots, or roulette. The winners of cards or dice can steal height from their opponent, or their height changes based on the result of the slot machine or roulette. There are many bunny waitresses working at this casino, including Asuna Ichinose. The rules are if your height becomes too small, you’re fair game to be stepped on, or be owned by any of the bunny waitresses. If your height reaches the roof, you will win a grand prize of your choice.
