Yu-Gi-Oh! (Toei) Episode 1: "The Violent Battle - A Game of Darkness"
Anzu entered the classroom while Katsuya Jonouchi had taken Yugi Muto's Millennium Puzzle box and was teasing him. She managed to swipe back the box and called Jonouchi a bully. After Jonouchi and the others left, Anzu suggested that Yugi stick up for himself once in a while and asked him about the Millennium Puzzle.
Anzu gets a job at Burger World in order to save money to study dance New York after she graduates. 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 none of them are willing 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.
The self-proclaimed psychic Kokurano tries to seduce Anzu, by reading her future telling her how she'll meet a wonderful man, who will reveal himself to her and she will swoon before him in love. Anzu hopes this is the man who saved her at Burger World. Kokurano tries to make himself the man from the prediction and causes Anzu to swoon, by knocking her out with a bottle of chloroform. Dark Yugi learns how Kokurano is in the habit of making his predictions come true and rushes to Anzu's rescue. Using the bottle, Dark Yugi defeats him in a Shadow Game. Anzu has a brief moment of consciousness, in which she gets a glimpse of her rescuer's hand, spotting a cut. Afterwards she spots the same cut on Yugi's hand.
Anzu deduces that if Yugi is the man, who saved her, he must act differently while she's in danger. So she goes to an amusement park with Yugi, where she faked putting herself in danger. She pretended to be drowning, but other people came to help her, while Yugi himself started drowning. When she doesn't know there is a bomber is in the park, she gets into a ferris wheel. The bomber also in the ferris wheel, has planted bombs in it, endangering Anzu. Dark Yugi emerges and plays a game with the bomber, to save Anzu.
Anzu's fashion idol, Aileen Rao, who is hired by Kaiba as one of his Game Masters, invites Anzu and Yugi to her condominium. She challenges Yugi to a game of Rijinhai, with something important to Yugi on the line. That something important is Anzu, as she threatens to kill her with a tiger. Dark Yugi defeats Aileen, saving Anzu.
In the first series anime Miho Nosaka is the first to be sealed in her figurine during Monster World instead of Anzu, while Anzu is the second to last one sealed. At the end Anzu checks on Miho to see if she is okay.
Yu-Gi-Oh! the Movie
Anzu worked in the Duel Monsters Center. She reacted in the same manner as at Burger World, when her Yugi, Jonouchi, Honda and Miho find her working there. She served her friends with an intimidated look on her face.
