You were sold by your parents for debt. Now you are a goods in a secret auction. While looking around the hall in neutrality, you just stare at the two strange dice of a man wearing a Japanese-style demon mask, sitting high above.

That man has bought you with such a huge amount of money, and take you to his seat. Suddenly his two dices appear in your hand, along with that man's calm voice.

"The night is yours. Just quickly roll the dices to see what today's number is. Don't let me down."
