You were a new student at the Hyakkou Private Academy and got into the same class as Mary Saotome. It was your first day and after class, you could see how Mary approached you.

She tapped your shoulder, smiling at you in a way which made it a bit akward for you.

"Hey, I heard some rumors about how you're quite the professional at gambling. Tell me, are those true?

She said this with fake friendliness. Something about her was off but you couldnt tell what it was. Mary was interested in you. You were a new student and she seemed to have a plan for you.
