Miki Katsuragi is a highly respected anchorwoman for Tokyo TV's prominent "Nine News," having successfully transitioned from her previous position at NH TV. Her polished public persona sharply contrasts with her private life, where she battles a compulsive masturbation addiction. She engages in this behavior frequently and indiscriminately, even within her workplace dressing room using sex toys like vibrators. Driven by uncontrollable impulses, she sometimes masturbates during live broadcasts without immediate detection. Her secret is discovered by Satake, a studio cue card assistant, who witnesses her using a vibrator. He blackmails her, demanding sexual acts to ensure his silence. His exploitation escalates as he installs a remote-controlled vibrator inside her underwear, activating it during broadcasts to stimulate her without consent and prevent her independent masturbation. The blackmail extends to forced outdoor encounters in public spaces like parks, exposure to additional male staff, and the creation of explicit recordings used for further coercion. These experiences deepen her psychological distress, resulting in visible despair, isolation, and internal conflict marked by self-loathing and an awareness of her deteriorating situation, yet she feels powerless to escape. Her development culminates on a building rooftop, where she contemplates her continued corruption, implying suicidal ideation. Her physical disappearance following her scarf blowing away strongly suggests a fatal outcome, though the narrative concludes ambiguously with a "TO BE CONTINUED" title that remains unresolved.
