Rebecca cries in sorrow . Joey tells Yami Yugi to get back to his senses and focus . He even tosses him to the ground , attempting to snap him out of it . The Nature of Doma . Professor Hawkins speaks of what he ' d decoded so far of the underwater ruins : he speculates that Doma may be descendants of the " legendary paradise " : Atlantis . He ' s convinced that it isn ' t a legend : the undersea ruins were the ruins of Atlantis . The texts he ' d decoded spoke about a King who ' d , along with a " Monster " , destroyed the whole city . Joey guesses that the information contained in those Chronicles had to be important , given how Doma is trying to make sure no - one can decode it . The Professor suggests going to see the fragments being exhibited in a Florida museum . Joey thinks of how to arrange for them to get to Florida . Switching Sides . Meanwhile , Rex Raptor and Weevil Underwood catch up to Rafael and jump to his helicopter . Alister flies them to a corporate building property of Doma , where Weevil and Rex are eager to join Doma ' s in order to gain power and not being losers for the rest of their lives . Rafael reports the success of his assignment , but Valon and Dartz correct him : he did defeat Yami Yugi , but the seized soul was that of Yugi . Rafael , shocked , states that he was Dueling Yami Yugi , so he should have captured his soul when he lost . Dartz explains to Rafael about Yugi ' s split personality case , which Weevil and Rex are confused about . Rafael apologizes and requests to Dartz to be given another chance at getting the Yami Yugi ' s soul . Curiously enough , today Dartz is dressed like a businessman , most likely to camouflage his identity from other people working in this corporate building . Rafael requests one more opportunity , and both Rex and Weevil plead to Dartz to let them join . Dartz hands them 2 blank " The Seal of Orichalcos " Cards out two Orichalcos Stone s for Rex and Weevil to get : they reach out for them and barely pass the test , thereby obtaining 1 " The Seal of Orichalcos " Card each . Rafael guides them into a big card room and given access to an almost limitless supply of Cards ( except the God Cards and the Legendary Dragons ) , in order to improve their Deck s . Both complain upon the announcement , but Alister informs them that even if they had them , they ' re not Cards they could use . They then let greed move them and prepare their new Decks . Dartz tells them that they have the task of defeating the Pharaoh and Joey . Kaiba ' s Anger . In the meantime , Seto Kaiba is irritated by the fact that no further information can be found regarding Doma . Mokuba Kaiba asks of him if he plans on facing Alister again . He feels guilty because of the incident in which Alister ' s brother was killed . Seto replies that unless they ' re defeated , their dreams won ' t come to happen . The phone rings , irritating Kaiba . An operator reports Joey is contacting them . Joey quickly tells Kaiba that they have clues about Doma and need to get to Florida . He unconsciously blabbers about Yugi losing his last duel , making everyone look annoyed and Yami Yugi look away . Kaiba realizes that Joey was telling the truth and becomes enraged , even to the point of calling Yami Yugi a ' disgrace to the game of Duel Monsters ' . He slams the phone on its place and then makes a smug smile . Seto Kaiba : " " Yugi lost ! ? Yugi gave his Duel Monsters championship crown to some nobody ! ? No one deserves that title but me . " " Yami Yugi : " " Hold on . . . " " Seto Kaiba : " " I don ' t want to hear another word . You ' re a disgrace to the game , Yugi .
