Unlike many schools, attending Gambling University prepares students for their time in the real world. Since many of the students are the children of the richest people in the world, the academy has quirks that separate it from everyone else. During the day, it is a normal school, teaching its students history, language, and more. But at night, it becomes a gambling den, teaching them the art of dealing with money and manipulating people. Money is power; those who appear at the top of the games are standing at the top of the school. Yvana Vallero, a seemingly naive and good transfer student, is ready to try her hand at Ymer's special curriculum. Unlike the rest, she is not playing to win, but for the passion of gambling, and her borderline insane way of gambling can bring too many new cards to the table.
