Naomi Hayakawa is the wealthy heiress and most admired student at her private Catholic all-girls school, renowned as its most beautiful idol. Her father presides over the family firm, while her younger brother, Akira, is the designated heir despite Naomi's seniority. Beneath this respectable exterior, Naomi leads a secret life as a hardcore dominatrix fascinated by bondage, exhibitionism, and power play. She recruits younger students as "pets," swiftly seducing transfer student Rie Komatsuzaki. Naomi demands Rie and another girlfriend, the devoted right-hand enforcer Midori Omori, address her formally as "oneesama." Midori serves primarily as a lookout and henchman, though Naomi punishes her for disobedience. Naomi's family shares her proclivities for BDSM and voyeurism. Her deceased mother, who succumbed to alcohol-related issues, engaged in similar activities with her father's tacit tolerance. Naomi openly acknowledges to her father that her interests mirror her mother's, though she prefers female partners. During a summer home gathering, Naomi orchestrates an S&M orgy attended by her father and brother, forcibly initiating Akira into the family practices. Naomi's influence gradually transforms Rie from a submissive partner into an assertive dominant. After graduation, Naomi departs Japan for Paris, seeking escape from her family's toxic influence to avoid destructive behaviors. She maintains contact with Rie, expressing hope for a future reunion as equals and lovers. Before leaving, Naomi "gifts" Rie a new student named Arisa, ensuring the cycle of dominant-submissive relationships continues. Later media presents an alternate-universe version of Naomi. A sequel novel, "Escalation: Die Liebe," depicts Naomi briefly returning to Japan, manipulating Rie further before departing again. This story introduces characters like Yukari and Tomoe but is considered a separate continuity due to inconsistencies. Across all iterations, Naomi's legacy perpetuates a tradition of power dynamics and hidden desires within the school.
