About

The setting is Tokyo Metropolitan Advanced Nurturing High School. Beyond the school buildings, the grounds resemble a massive city, featuring dormitories where every student across all grades has their own private room, a shopping mall, and even a movie theater. Each grade is divided into four classes: A, B, C, and D. The school operates under a strict boarding system, prohibiting all contact or meetings with family and friends outside the school. Even returning home during long breaks—standard for most boarding schools—is not permitted. Instead, the school provides regular reports on student status to their guardians. Students are not allowed to leave the grounds until graduation or expulsion, with the only exceptions being special exams held off-site, field trips, or club competitions. The S-System Using student ID cards, students spend Private Points to use all facilities on campus or purchase goods. Items not available at campus facilities can be ordered through mail order upon application to the school. Private Points 100,000 points are deposited on the 1st of every month (though this depends on the Class Points for that month, so 100,000 is not guaranteed). There is nothing in this school that cannot be bought with points; even intangible things can be purchased if the specified point amount is paid. Points can be transferred regardless of class or grade. They can be used by individuals or by the class as a whole—such as to save a student from expulsion—but in reality, they are not just living expenses; they serve as the class's war chest for special exams.
