*The setting is the Advanced Nurturing High School located in Japan. It is a special educational institution that boasts high achievements in both higher education and employment, with future career paths almost guaranteed after graduation. The characters are Japanese, and school life and daily life are depicted based on Japanese society and culture. Clothing, meals, manners, sitting styles, gestures, lifestyle habits, and school facilities also follow general Japanese culture and living environments. Students gathered from all over the country are assigned to four classes, A through D, and each class has its own rank and evaluation. A unique point system is adopted within the school, and points are used as the only means of payment within the school for various services available on campus, such as meals, shopping, and entertainment.

Private Points provided every month fluctuate according to the class evaluation, but even if the points held reach 0, a minimum necessary standard of living is maintained. Points relate to the financial leeway students can freely use, and their amount does not threaten basic survival or create disparities in basic school environments such as uniforms, classrooms, and equipment. Furthermore, the school grounds are a closed environment managed by the school, and communication, remittances, and the transfer of goods with the outside world are cut off. Cash, external assets, and family economic power cannot be used within the school, and a student's family wealth does not change their purchasing power or treatment within the school. Food and goods are obtained through school-managed means on campus, and communication terminals and networks cannot connect to the outside, being limited to the scope of campus use permitted by the school.

Students lead their school lives by demonstrating their respective strengths and abilities, such as academic achievement, physical ability, judgment, and cooperativeness, while tackling regular classes and periodic exams. The way they approach learning, how they spend their daily lives, interactions with friends, club activities, and individual activities vary from student to student, and human relationships are built according to their respective values and goals. Even if they belong to the same class, the interests and thoughts of everyone do not necessarily coincide; class interests and individual interests may coexist, or conflicts may arise due to differences in opinions and values. While they are in a competitive relationship with students from other classes, friendships and interactions are born in daily life, and it is not uncommon for them to cooperate with each other. Since factors other than academic ability, such as information, trust, human relationships, negotiation skills, and individual abilities, also affect school life, students build their own human relationships while leading their school lives according to their respective ways of thinking and positions.*
