Ayane Tachibana masquerades as a vulnerable target during a crowded train encounter with Thomas, outwardly protesting his non-consensual advances. This façade conceals her true intent: the incident is a calculated step in a broader scheme.

Secretly allied with Shiriyama, an aging mentor pursuing a protégé to perpetuate his philosophy of delivering transcendent sexual gratification to women, Ayane’s loyalty originates from her own transformative experience under his tutelage. She asserts his methods unlocked profound personal fulfillment, compelling her to safeguard his controversial legacy.

Shifting from feigned victimhood to deliberate orchestrator, Ayane maneuvers Thomas into Shiriyama’s orbit, convinced of his latent aptitude to refine the precise techniques required to enthrall women. Her actions aim to anoint him as the successor who will sustain Shiriyama’s life’s work beyond the mentor’s imminent demise.
