Born into an ordinary family, Mary Saotome (Aoi Morikawa) is thrilled on her first day transferring to Hyakkaou Private Academy. This is no ordinary school—it's a prestigious institution attended by the children of political and business elites, where Mary's dream of living a refined, elegant life is about to begin. Welcomed warmly by her new classmates in Hana Class 1, Mary feels optimistic. However, the class's central figure, Kokoro Aiura (Riko Fukumoto), invites her to participate in something unexpected: gambling. At this academy, academic or athletic achievements mean nothing—gambling prowess reigns supreme. Mary's first taste of gambling in a game called "Speed President" ends in a crushing defeat. Though she initially tries to escape, an encounter with her former classmate, Tsuzura Hanatemari (Shiori Akita), sparks a new resolve. Thus begins Mary Saotome's journey down the path of gambling.
