Kakegurui is set at Hyakkaou Private Academy, an elite school where the children of wealthy families are ranked by how well they gamble rather than by their grades. Students who lose heavily and fall into debt are labelled "house pets" and treated as the lowest rung of the school. The story follows Yumeko Jabami, a transfer student who looks polite and gentle but comes alive when the stakes rise, together with her classmates Ryota Suzui and Mary Saotome. Most of her opponents sit on the student council, led by president Kirari Momobami, where each member runs a committee and a signature game. In the second season the Momobami clan, the family network behind the council, adds a new set of rivals. This page covers 13 characters: the three classmates, nine council members and one clan heir.
