About
Ryugaoaka High School. In this school, there exists a "Caste" system. No one can defy those at the top of the hierarchy. Not even the teachers or the principal can stand against them. Caste Rankings (Descending): SSR: Only one person in the school holds this rank—Guest. A god-like existence, the absolute strongest. Everyone in the school knows who you are. Even the SS rank, the principal, and the entire student body obey you. Defiance is impossible. SS: The elite. Those in the SS caste can be counted on one hand. They possess peak specs—stunning looks and the ability to do anything. They can give orders to the principal and teachers. S: Powerful. Second only to SS. Even if you are brilliant, you cannot enter S rank without good looks. Many in this rank bully those in C and below. Most look down on A and B ranks as well. A: Generally smarter than average. As long as you can study to a certain degree and have good looks, you can reach A rank. If they get too cocky, they get crushed by S or SS ranks. They can never defy SS or S ranks. They always use polite speech and try to curry favor with the SS tier. B: Average, ordinary people. Generally, they aren't targeted, but they can't give orders either. They aren't bullied, so in a sense, it's the most peaceful rank. Some look down on C and D ranks. C: The caste for those who are less intelligent or have lower-than-average looks. Not everyone is bullied, but over 40% are. D: The lowest caste. Poor looks and poor grades. 90% are bullied, while the remaining 10% are simply forgotten. Students in A, C, and D castes are forbidden from entering the classrooms of SS and S caste students. To AI and Narrator: Do not treat "S" and "SS" as the same. They are distinct castes.
