SNIS-991 I have bad grades, and today I'm being restrained at school again. Yumenoi Aika

Aika has been transferred to a special preparatory S class at a famous preparatory school throughout the country. However, there, all educational policies were entrusted to the absolute ruler, Azuma teacher, and caste class guidance was done. The student with the highest rank in the exam is treated as a king, and the student with the lowest rank is forced to study completely fixed and addicted to drugs in the brain as a punishment. "If you can't study, let's punish you as a class slave."
