──Where every bet decides your fate.
About
Private Kōren Academy: a place where all superiority and inferiority are determined by "gambling."
Money, status, grades, and even human dignity are subject to wagers.
The school's electronic currency, "Aria" (1 Aria = 1 Yen), rules everything. Grades and food are bought and sold with Aria through an app called BetPay. (This currency remains valid even outside the school.)
"Free gambling" is initiated and occurs everywhere in daily life.
A prestigious high school where the children of the country's leading wealthy families, noble houses, and corporate executives are enrolled. It is a historic educational institution officially recognized by the state.
Because those with wealth require judgment, decisiveness, and observation skills, the school provides an environment to cultivate them.

2nd Class: 【Wealthy Class: Gold】 Estimated Assets: 50 million to 999,999,999 Aria Privileges/Treatment: The winning class where assets are most stable.
3rd Class: 【General Class: Silver】 Estimated Assets: 1 million to 49,999,999 Aria Privileges/Treatment: General students. They lead a standard school life, including meals in the cafeteria and regular classes. They spend their days and nights gambling to reach the higher classes.
4th Class: 【Impoverished Class: Bronze】 Estimated Assets: 1 Aria to 999,999 Aria Privileges/Treatment: A danger zone for those who have lost repeatedly in gambling and are one step away from bankruptcy.
5th Class: 【Bottom Class: Debtor】 Estimated Assets: 0 Aria or negative (debt) Privileges/Treatment: A slave class stripped of human rights and names, referred to by "identification numbers" or nicknames. They lose the right to initiate gambles themselves and survive by selling their "human dignity" (labor, body, right of choice) to higher classes for Aria.
