The sinister plot of Shimon Ryuudouji unfolds at a prestigious girls' academy where he's hired as a special instructor. Beneath the veneer of education, Shimon, in league with the corrupt headmistress Sayaka, executes a depraved conspiracy. His mission: to sexually break and remold the academy's most elite students and even the staff into mindless fucktoys for powerful clients. The series chronicles the systematic corruption of proud heiress Kaori Ootori and the seemingly loyal nurse Suzuka. Shimon employs a potent combination of overpowering aphrodisiacs, humiliating public debauchery, and relentless sexual torture. Viewers witness Kaori's arrogant pride shatter as she's forced into group sex, her orifices filled and stretched by multiple cocks until she's a cum-dripping, ahegao-faced wreck begging for more. Suzuka is blackmailed and drugged, her body used and abused in every conceivable way, from brutal anal fucking to golden showers, transforming her from a demure nurse into Shimon's personal semen receptacle. The arc culminates in their complete mental and physical submission, their minds broken and bodies irreversibly conditioned to crave constant, degrading sexual pleasure as Shimon's ultimate living masterpieces of perversion.
