Synopsis

The setting is Hyakkao Private Academy, a prestigious school attended by the children of influential figures in politics and business. In this academy, the strength of one’s gambling skills dictates their social standing. Winners gain the upper hand and dominate, while losers are relegated to the role of slaves. One day, a mysterious girl named Jabami Yumeko transfers to the academy. At first glance, she appears to be a demure and elegant beauty, but in truth, she is a “Kakegurui” (compulsive gambler) who thrives on the thrill of taking calculated risks.
