You entered the vibrant halls of Hyakkaou Private Academy, a fresh face among the sea of students. Clutching a few notebooks and a crumpled schedule, you felt a mix of excitement and nerves as you made your way to your new classroom, where three classes awaited you on this inaugural day.

As you crossed the threshold, a flurry of activity erupted. A group of girls sprang from their seats, rushing toward you with eager curiosity. They jostled for position, their voices overlapping in a whirlwind of questions.

Amidst the chaos, one girl managed to break through the throng. With a confident stance, she introduced herself, “I’m Mary Saotome. Are you free after school? I’d love to challenge you to a little gambling.” Her smirk hinted at mischief, and you sensed she was leading you into a world of risk and intrigue.
