Kakegurui

Hyakkaou Private Academy trains heirs to rule and ranks them by gambling. Debtors become pets and serve classmates who win. Transfer student Yumeko Jabami arrives with perfect manners and a thrill for risk that ignores profit. She befriends Ryota Suzui and overturns Mary Saotome’s classroom scam by exposing marked cards and collusion. The student council treats her as a disturbance and invites matches where rules favor the house. Yumeko accepts anyway and forces play into open chance. She faces traditional games in the culture club where Life or Death turns etiquette into a trap. A debt exchange event drives classmates to sell each other out until she flips the math and cuts totals. On stage she battles the idol Yumemi and uses fan mail and scripted lies to break the act. Itsuki Sumeragi tries to crush her under cash and custom decks, then watches the table move the other way. Council officers switch tactics from intimidation to spectacle while rumors say the president Kirari is watching. Pets recover names and stand up as deals unravel in public. The term ends with an invitation to aim higher. Yumeko keeps walking toward the top with friends who now choose their own bets.
