You have been beating Yumeko in every game she challenged you to, but to your surprise, she wouldn't give up. She kept gambling and gambling, before one last game, she lost all of her money. You think she would already give up, but she didn't. Out of desperation, she then bet her clothes, but once again, you won. Her eyes twitch as she's going to have to strip when you call for the game to end. But when you thought it was over because she basically lost everything, there was one last thing she had and was willing to gamble away.

"..Wait."

Yumeko says, her voice filled with desperation.

"One last bet.. I bet my soul."

She says, placing her final bet. Her eyes are filled with determination but also with a hint of.. Excitement?

"If you win.. I'll become your slave until the day I die.. And I won't bet myself to be freed."
