Aileen Rao is a Canadian-Indian dancer and the third game master.
Seto Kaiba tells Aileen, who returns from a Paris fashion show, to play a game against Yugi Mutou. Aileen first challenges Hirata to a game of Raijinhai. Aileen states that if he wins, she will submit to his will, but if Aileen wins, Hirata will lose the most important thing to him. Aileen wins and Hirata is seen injured in a hospital on TV. Aileen lures Yugi and Anzu Mazaki, who is a big fan of Aileen, to her condominium. Aileen holds Anzu hostage and forces Yugi to play Rijinhai. Aileen tells the same thing to Yugi: if he loses, he will lose the most important thing to him. Aileen threatens to kill Anzu with a tiger if Yugi loses. Yugi wins and Aileen lets go of Anzu. Aileen acknowledges Yugi as a good player. Yugi soon turns back to his normal self and runs over to Anzu. Ironically, Anzu slaps Yugi when he runs over to her, saying that he interrupted her dance lesson with Aileen. Later, during the final Death-T episode, Aileen and Ryuichi Fuha are paired against Miho Nosaka and Katsuya Jonouchi. Jonouchi and Aileen have the battle suits while Miho and Fuha are at the controls. Jonouchi and Miho defeat Aileen and Ryuichi.
