Immoral relationships with the opposite sex, habitual lateness, ignoring teachers. Problematic students are gathered together and taught greetings, etiquette, respect, and shame. They are forced to compete naked in front of everyone. Even if they don't want to, they are forced to undress, and when the measurements are finished they are made to say "Thank you." If their behavior or test results are bad, they are punished. They are spanked and broken. And then male fertility tests are performed. They are told to "cooperate with their friends" and are made to use their bodies to serve them!
