EMMA Queen, furious that a man who had sworn to become her "slave" had stopped contacting her and even hidden his whereabouts, dispatched her younger sister, KYRIE Queen, to investigate his home in Tokyo and bring him back to Osaka. The man, though previously exposed to his latent masochistic tendencies during a prior session, had refused to accept it, convincing himself it was just a nightmare by changing his phone number and moving. However, as EMMA Queen resumes his training with a blend of harshness and tenderness, his suppressed submissive nature begins to surface uncontrollably.
