The series follows the seemingly perfect and untouchable student council president, Ibuki Hyoudou. Beneath her pristine and commanding exterior lies a dormant, deep-seated masochism waiting to be unleashed. A cunning male student discovers this hidden vulnerability and devises a relentless campaign to break her spirit and awaken her true desires. Through a series of calculated torments, public humiliations, and intense sexual encounters, he systematically dismantles her pride. Viewers watch as Ibuki's initial resistance crumbles, replaced by an insatiable craving for degradation. Each episode escalates the depravity, pushing her further into her submissive role. She is subjected to bondage, forced into lewd acts in front of others, and made to orgasm from the sheer shame and pleasure of her complete submission. The arc culminates in her total transformation from a flawless president into a dedicated, pleasure-seeking masochistic slave who finds her ultimate fulfillment in being used and dominated entirely by her new master.
