Ayako, a teenage girl from Kyoto, wins a substantial lottery prize alongside two friends. She and her friend Haruka use the winnings to move to Tokyo, aiming to pursue their ambitions. Their plans shift when they encounter Fumiko, a distressed girl who reveals she attempted suicide after being sexually assaulted by a music producer. Ayako participates in the decision to allocate their lottery funds to form an idol group, incorporating Fumiko.

The group adopts the name "Celebrity Idol Group" and faces significant challenges gaining industry acceptance. Established music producers actively undermine their efforts using unethical tactics. Ayako and the group experience exploitation, including the sabotage of their media opportunities. The situation escalates when producers deceive them into boarding a helicopter under false pretenses. Ayako is transported against her will to an uninhabited island, where the producers intend to sexually assault her and the other members. This culminates in a confrontation involving aerial vehicles and an escape attempt.

Ayako's initial motivation is seeking fame and success in the idol industry. Her experiences in Tokyo expose her to industry exploitation and violence, with the events on the island representing the peak of this victimization. The resolution of her story involves the group's escape from the island and the thwarting of the producers' plans. This event concludes her documented character arc.
