The Wild Card (Devil x Reader)

You had ran away from your home in the city on Inkwell Isle three. You're family was super rich, and because of that, you had to be perfect. You hated it, so you ran away.
You've been homeless for 6 years.
Suddenly, there was an announcement that two little boys defeated King Dice, and the Devil, freeing everyone on the isles from his debt.
You were happy to hear that, but you were also a bit curious. What was the Devil doing now? And what was going on in that casino?
