Synopsis
Mary Saotome is audacious, insolent, and defiant, but also highly intelligent. When she transfers to Hyakkaou Private Academy—a school where a student's social worth is determined by their gambling prowess—she scores a stunning victory against a classmate, instantly drawing the attention of the cunning student council. At Hyakkaou, the bottom of the rigid hierarchy is decided by the lowest gambling earnings, leaving Tsuzura Hanatemari's future bleak. As Tsuzura's childhood friend, Mary resolves to climb the ranks and earn enough money to free her from the oppressive system. Mary's tenacity and refusal to lose drive her to surpass and humiliate even the toughest opponents, though certain student council members appear to have larger schemes in store for her.
