Yumeko stops being the protagonist halfway through and becomes the thing everyone else has to survive. The second season abandons the thrill of watching her win and builds something colder: a school where power shifts so fast that yesterday's alliance becomes today's liability. By the end, you're watching people break not because they lost a gamble, but because they finally understood the cost of playing in a game designed to make you disposable.

Yumeko Jabami's gambling prowess has made her famous at Hyakkao Private Academy, a school for the children of the very rich where gambling sits at the heart of the curriculum, while the student council's standing is slipping and infighting spreads in its ranks. To shake things up, council president Kirari Momobami calls an election for her successor. Every student receives a single chip, and whoever holds the most after thirty days becomes both council president and head of the Momobami Clan. Word of the contest stirs the Momobami branch families into action, and eleven transfer students arrive at the academy, each with special talents and each determined to seize the school and the clan. Chips are not the only thing players can wager, and Yumeko, ever hungry for tougher opponents and higher stakes, means to clean house whatever she has to put on the table.
