Masakazu Meguro enters a blind date with Lucie Suginami, their connection sparked by mutual fascination with the paranormal. The encounter takes a dark turn when he sexually assaults her, igniting Lucie’s resolve for vengeance. Leveraging the SCM device’s rules, she challenges him to a pachinko parlor contest: whoever gathers the most balls claims victory, while the loser becomes the winner’s enslaved subordinate. Unaware of Lucie’s strategic foresight, Meguro accepts, only to discover she had stockpiled trays of balls in advance, securing his defeat.

Bound by the SCM’s enforcement protocols, Meguro is compelled into servitude, obeying Lucie’s commands without defiance. The system mandates compliance even during acts of self-inflicted violence, though it safeguards against lethal harm. His subjugation underscores Lucie’s transformation and the SCM’s dual role as a tool of justice and ethical contradiction, framing their dynamic within the narrative’s exploration of power and retribution.
