SNIS-991 I got bad grades and am still stuck at school today. - Aika Yumeno

Aika has been transferred to the special S class of a nationally famous preparatory school. - However, all educational policies were left to the absolute ruler, the Toni teacher, and guidance was given in a caste-based manner. - The student who ranks highest in the exam is treated as a king, and the student who ranks lowest is punished by being completely fixed and forced to study hard while having his brain drugged. - ``If you can't study, I'll punish you for being the class bastard.'' Aika, a big-breasted schoolgirl, is pinned down for failing and undergoes punitive training!
