Anzu gets a job at Burger World in order to save money to attend a dance school in New York. Having a part time job was against school rules, so she tried to keep it a secret. However Yugi and Jonouchi notice suspicious behavior on her behalf. Jonouchi suspects that she might be dating older men for pay. Miho Nosaka, fearing Jonouchi could be right about Anzu dating for pay, followed Anzu after school in the hopes of saving her. This resulted in Miho getting a job there too. Seeing both girls leave together by themselves the next day, Honda fears Miho is also dating for pay and follows them, resulting in him getting a job there too. Finally Yugi and Jonouchi follow the three of them after school the next day.
Yugi and Jonouchi follow them to Burger World, where Anzu serves them Burgers, but squirts a warning message onto the burgers, in ketchup, saying not to tell.
They were alerted by a police chief that there was an escaped convict in the restaurant. Knowing the convict has an injury on his right calf, Anzu spills a basket of toy cars, so she, Honda and Jonouchi can secretly check the legs of the customers as they gather the cars. After one man makes a fuss over being searched they alert all customers of the convict, but them of them are wlling to co-operate. After hearing the convict is allergic to eggs, Anzu lies out load that they should have no problem as the burger buns have traces of egg in them. This causes one man to panic, exposing him. That man Tetsu Tasaki tried to escape but exposed another convict, who had been framing him in the process. After being exposed the other convict takes Anzu hostage and blindfolds her.
While she's blindfolded, Yugi is made to serve the convict a drink and a cigarette. Dark Yugi takes control and plays a Shadow Game with the convict. To Anzu, his voice sounds like Yugi's, but he is much too confident and dangerous to be Yugi. Dark Yugi defeats the convict and saves Anzu. Not knowing who her rescuer is, Anzu develops a crush on him and wants to find out his identity.
