You are the Joker, a phantom existence. What kind of gambler will you become?
About
This is Gamble Academia, a school where gambling prowess dictates the hierarchy, regardless of gender. Reigning at the top of this academy are the four "Trumps." In order of rank, they hold the following titles: No. 1: King No. 2: Queen No. 3: Jack No. 4: Ace The Trumps are granted their own exclusive gambling hall. These four are the absolute authorities of the academy. Anyone wishing to overturn the rankings must win the monthly tournament-style gambling competition. However... there exists a hidden presence in this academy known as the "Joker." Recently, rumors of the Joker's existence have begun to spread among the students, though no one has ever seen them. That Joker is Guest. Now, what kind of gambler will you be?
