With " The God of the Obelisk " and " Gadget Soldier " beside him , Kaiba thinks that he has to go with his instincts . He ' s Summoning " Blue - Eyes !

He sacrifices " Obelisk , " and " Gadget Soldier , " much to Ishizu ' s surprise . Dark Marik is also shocked that Kaiba is sacrificing a God , as are Dark Yugi and Jonouchi . Ishizu thinks that she didn ' t predict this as Kaiba tells his " Blue - Eyes " to come out . The fearsome white dragon appears above Kaiba with a roar . Dark Yugi wonders why Kaiba Summoned his dragon at the cost of losing God . Dark Marik furiously looks at the Millennium Rod , asking if its power somehow changed Kaiba ' s decision . He thinks that he knew it . The Duelist carved in that stone , the image of a priest holding the Millennium Rod , the " white beast handler . " Kaiba asks Ishizu if his dragon existed in her so - called vision of the future , but Ishizu is too shocked to respond . Kaiba grins , claiming that it couldn ' t have ; because this is his future . With only 1400 Life Points against the 3000 ATK of " Blue - Eyes , " Ishizu knows that she ' s lost , and she closes her eyes in acknowledgement . Kaiba declares his Battle Phase , ordering his " Blue - Eyes " to attack . As everyone else watches , lightning builds in the dragon ' s jaws , and Kaiba orders " Blue - Eyes " to tear open the future . The " Blue - Eyes White Dragon " attacks with " Burst Stream of Destruction , " and the lightning blast impacts beside Ishizu , reducing her Life Points to zero . Kaiba yells that he won . Ishizu tells Kaiba that he did it . He changed the future with this Duel . And now he has become a true possessor of a God Card . Kaiba quietly replies that everyone has something they believe in , even deeper than believing in Gods . All he did was trust that . He turns and begins to walk away . Ishizu tells Kaiba that she took something important from the Duel : the light of hope . Her Millennium Tauk showed a future of darkness , but perhaps that future can change . She glares at the smiling Dark Marik , thinking that even if she had won , she only had a slight chance of saving her brother . She tells Kaiba that people can change the future , but Kaiba scoffs , stating that those who allow themselves to be chained by " future " or " fate " will never see this light Ishizu talks about as he walks away . Ishizu wonders if one of the four Duelists who survived the quarter - finals can save her brother . She cannot see that future , but she will believe in that . Isono declares the fourth match of the tournament over , and Seto Kaiba is the winner . Kaiba walks past Dark Yugi , commenting that it ' s almost time to settle the score , and Dark Yugi agrees . Anzu thinks that its just like the carving , they all saw it . Their fate is carved in the stone . As the airship flies through the air , Kaiba walks into the computer room where Mokuba is translating the text on the " Ra " card . Mokuba tells his brother that he knew he ' d win , and Kaiba asks if the image of the " Ra " card has been translated . Mokuba replies that he ' s almost done . Kaiba looks at the image , and to his utter shock , he can read the text ; it ' s as clear to him as plain Japanese . And it tells about " Ra ' s " special power . He sinks to his knees , a hand covering his forehead , and as Mokuba asks if Kaiba ' s okay , Kaiba asks why the Gods showed him this horrifying knowledge .
