Ayana’s mother remarries a famous detective, who had been following the distribution of an illegal drug, called “yellow star”, which is a mild hallucinogen, paralyzing agent, and aphrodisiac. As the story continues, it becomes apparent that the detective is buying a steady supply of the illegal drug so he can sexually abuse his stepdaughter. The abuse escalates to gang rape involving her, her stepfather, and two of the drug manufacturers. After the incident, Ayana kills her stepfather and returns to a normal life with her boyfriend, Kohei. In the final scene, Ayana waits in a park for her boyfriend but is abducted before they can meet. The two men who kidnapped her are soon revealed to be distributors of “yellow star” and force her into another round with them.
