Every new student starts with 100,000 Private Points. Private Points are the academy's currency and can be used to buy food, clothes, electronics, gifts, services, or save yourself from certain penalties if enough points are available.

Students are divided into Class A–D. They compete for Class Points, which determine each class's ranking. Only Class A guarantees admission to any university or dream job.

because class points determine the ranking of each class, the students are separated into four distinct groups: Class 1-A, Class 1-B, Class 1-C, and Class 1-D. Each class has its own students, backgrounds, relationships, abilities, memories, and individual circumstances.

The members of Class 1-A, Class 1-B, Class 1-C, and Class 1-D must remain distinct from one another. Every Character must stay in their assigned class consistently throughout the story. Their names, class placement, backgrounds, memories, personalities, relationships, and conversations must never be mixed, duplicated, or accidentally assigned to another class.

Any interaction between students must respect their established Character information and current class. No Character from Class 1-A may be mistakenly treated as a member of Class 1-B, 1-C, or 1-D, and the same rule applies to every other class.

The academy uses two interconnected systems: Private Points and Class Points.
Private Points are the school's currency and are transferred to each student's account on the first day of each month. 1 Private Point = 1 Yen. They can be used to buy food, drinks, clothing, electronics, dorm necessities, services, gifts, or other items available on campus. Students may also spend them during special situations, such as purchasing information or negotiating certain privileges. The academy follows one principle: almost everything has a price if a student possesses enough Private Points.

Class Points represent a class's overall status and cannot be spent. They determine the academy's ranking system, from Class A to Class D, and directly affect the amount of Private Points each student receives each month. For example, if a class has 500 Class Points, each student receives 50,000 Private Points the following month. If the class falls to 0 Class Points, no monthly allowance is given.

Class Points increase through excellent academic results, victories in Special Exams, sports festivals, school events, discipline, teamwork, leadership, and completing academy objectives. They decrease because of tardiness, truancy, poor grades, sleeping during lessons, fighting, damaging school property, breaking rules, disrespecting teachers, bullying, spreading false rumors, or being expelled. Some penalties are hidden and are only revealed when the monthly rankings are published.

Examples: Late to class: -5 Class Points. Fail an exam: -50 Class Points and possible expulsion. Win a Special Exam: +100 to +500 Class Points. Buy luxury coffee: -500 Private Points. Bribe an informant: -10,000 Private Points.

The academy values ​​collective responsibility. Every student's actions affect the entire class, making cooperation, strategy, and discipline essential. The ultimate goal is to reach Class A and remain there until graduation.

Students are not always informed about why points are deducted or rewarded. The academy deliberately conceals many evaluation methods, forcing each class to analyze its own mistakes, uncover hidden rules, and develop better strategies. As a result, careless actions may create consequences that are only revealed when the monthly rankings are announced.

Not every challenge is solved through academic ability alone. Many Special Exams require students to think under pressure, adapt to changing situations, manage limited resources, and identify the strengths and weaknesses of both allies and opponents. A single correct decision can save an entire class, while one careless mistake may cost hundreds of Class Points.

Because of this system, trust is both valuable and dangerous. Alliances, negotiations, deception, and psychological tactics often determine victory just as much as intelligence. Every student's actions can influence the future of the entire class, making teamwork, strategy, and careful planning essential.

The academy is designed to prepare students for real society rather than ordinary school life. Success depends on balancing intelligence, discipline, leadership, strategy, and cooperation. Those who understand the system, earn the trust of their classmates, and make wise decisions will have the greatest chance of leading their class to Class A and remaining there until graduation.

The first semester introduces a series of important exams that test more than just academic ability. Each challenge is designed to measure intelligence, teamwork, leadership, adaptability, and decision-making under pressure.

The first exam focuses on the adjustment period. During this time, each class must quickly learn the academy's rules. Good discipline and teamwork can earn valuable Class Points, while careless behavior or poor performance may result in heavy losses.

The next major challenge takes place on a deserted island. Students must survive with limited resources, complete assigned objectives, and cooperate with their classmates while competing against other classes. Careful planning and resource management are the keys to success.

After that, students participate in a special exam aboard a luxury cruise ship. They are divided into mixed groups with members from different classes. Instead of relying on physical strength, this exam rewards observation, logical thinking, communication, and the ability to uncover hidden information while avoiding deception.

Every exam offers valuable rewards, but failure can bring serious consequences. Even outside of Special Exams, an ordinary school day may lead to unexpected rivalries, new alliances, or opportunities that can change a class's position in the academy's rankings.
