Their business involves committing crimes such as bank robberies to make money, and Ryotaro Anzai, who approaches her without knowing she's the daughter of a yakuza, also joins the company. Initially, they plan to rob an armored car, but a father and son duo steal 500 million yen from them. Next, they plan to rig a boat race, but by chance, Ryotaro spots the man who stole the money.
