→Waking the Dragons
Mai saves Joey and his friends from a gang of bikers by throwing cards at them. Although the gang does not get a clear view of their rescuer, Joey gets a glimpse of one of her "Harpie Lady" cards as well as a glimpse of her in her helmet visor and begins to suspect that it is her.<ref name="ep 151" />
Yugi, Joey and their friends arrive at the [[Industrial Illusions]] headquarters to meet Pegasus but instead find Mai and are locked in. Mai faces Joey in a Duel, using "The Seal of Orichalcos", putting both players' souls at stake.<ref name="ep 151" /> Although Mai dominates most of the Duel, Joey makes a comeback after acquiring his [[Legendary Dragons|Legendary Dragon]]. When it becomes apparent that Joey is about to win (when he actually is trying to end it in a draw to save them both), Valon intervenes, using his fragment of the Orichalcos to break the seal, saving Mai.<ref>{{episode|Yu-Gi-Oh!|154|ref}}</ref> This greatly angers Mai as she claims to have had the Duel under control(Or so she thought).<ref>{{episode|Yu-Gi-Oh!|155|ref}}</ref>
Valon takes matters into his own hands and tries to defeat Joey before Mai can face him again. Joey manages to win and change Valon's attitude. Mai catches the end of the Duel and Valon tries telling her that Joey is a good guy. Regardless, Mai gets possessed by the powers of the Orichalchos again and faces Joey again. Joey accepts, realizing that he can never truly get through to her until she is freed from Dartz's control. Joey tries to convince Mai that Dartz has deceived her. Too exhausted from both Duels to play well, Joey nearly passes out as Mai is about to win. Mai finally sees through all of the deception and remembers everything that they went through, and as a result, doesn't declare her final attack and rushes over to catch Joey. The Seal, however, proceeds to take Joey's spirit because he no longer has the strength to continue, and therefore, loses the Duel. Devastated, she holds Joey close in her arms and tearfully tells him she won't let the Orichalchos take him away, as the Seal closes in. Before losing his soul, Joey pushes Mai away and throws her fragment of the Orichalchos in the air. She screams in agony as Joey loses his soul while breaking the fragment, her strong emotions finally freeing her from Dartz's influence. Afterwards, Mai sadly admitted she didn't want to win this way & questioned what did felt she gain gained nothing from robbing her friend's soul?.
In an attempt to pay back Joey and Valon, she tries to take on Dartz to beat him and win back their souls, but is instead confronted and defeated by [[Rafael]] at their headquarters, resulting in the loss of her own soul.<ref>{{episode|Yu-Gi-Oh!|174|ref}}</ref> Rafael later saves her life by pulling her unconscious body from the wreckage of the collapsing headquarters.<ref>{{episode|Yu-Gi-Oh!|177|ref}}</ref>
