Yuma Tsukumo finds himself walking along an old zig - zag raised path . He finally reaches the end where there is a gate , shaped like the head of a demon , wrapped in chains . He hears a voice saying that the one who opens this door will receive great power , but as compensation will lose something important to them . The artifact around his neck starts to react to this . Suddenly Yuma wakes up in his room sweating and realized it was just a dream . He sighs in relief , commentating that he had that dream again . The room is filled with various archaeological finds , he sleeps in a hammock and has a few " Duel Monsters " cards scattered across the floor . Yuma looks at his artifact and wonders about it , but he realizes it is 8 o ' clock and hurries to get up . Downstairs , Yuma ' s sister , Akari Tsukumo is surrounded by flat screen monitors and working on them . Yuma tells her off for not waking him , but Kari explains that she was busy with a news transmission and he should be waking himself up . Kari gets back to talking to her editor and Yuma makes a face at her before rushing out . Outside the house , Yuma looks at his Deck and recalls the reason for he had been sleeping - in ; He has stayed up until midnight working on his Deck in order to counter his classmate Tetsuo Takeda . Yuma is stopped as his grandmother , Haru Tsukumo , catches him by his messenger bag with her broom . She holds Yuma in midair , as his cards fall to the ground . Haru asks if he had breakfast , but Yuma says it doesn ' t matter as he is going to be late . Haru picks up one of the cards and Yuma explains that he had been working on his Deck last night . She says that Yuma must have had forty straight loses to Tetsuo , but Yuma corrects her saying it ' s closer to fifty . Haru yells at him that breakfast gives him energy for the day and without it , he will be weak at dueling . At the school gym , Yuma faces twenty stacked trapezoid blocks with a group of people watching . He claims he can jump it easily , but his friend Kotori Mizuki is anxious . Tetsuo smirks and asks if Yuma ' s " idiot show " is starting again . Yuma runs and leaps towards the blocks , but smacks into them and falls back . Kotori rushes over to see if he is okay and Tetsuo laughs that that there was no way he could have made that jump . Kotori tells Tetsuo off for laughing , but he continues and asks what Yuma will challenge next . At the swimming pool , Yuma attempts to show off again by claiming he can swim the full distance without taking a breath . Tetsuo claims that is impossible , but Yuma says he shall hold him to that and if he makes it , he will Duel him today to the end . Tetsuo watches and claims that Yuma will only add to his record of losses . A giant air bubble surfaces and Tetsuo laughs that he knew that would happen . Later Yuma plunges down onto his desk , claiming to be exhausted . He is joined by Kotori , who asks what exhaustion and calls him an idiot . Yuma claims that she doesn ' t understand how challenging it is to be him , but then he changes his mind and stands up declaring that it ' s what fires him up . Kotori waves her hand embarrassed by him and points out that even if he claims he can do something , it doesn ' t mean he can do it . However Yuma looks at his artifact and says that it ' s important that he keeps challenging it and one day he will be able to reach the end of the pool . Kotori notices him looking at the artifact and asks isn ' t it a memento of his parents , who were adventurers . Yuma remembers being given the artifact from his mother and says that it is and he believes it is a precious charm that will help him open any door of possibility . Kotori asks isn ' t he only looking for one door . Yuma confirms that he is , but it ' s a very big door and it ' s what will get him most fired - up . Afterwards the two of them dash to watch a Duel , where Kotori says that everyone loves dueling . Yuma looks around for Tetsuo and then places a D - Gazer over his eye . This creates a augmented reality , where he finds himself in a canyon , watching a large shark battling a girl on the dragon ' s back . Yuma states that if Kotori sees this she will realize that dueling is the greatest and a place where you become champion of the world . Yuma hears Kotori calling him to say that Tetsuo is Dueling . Removing his D - Gazer , Yuma sees what ' s happening in reality and finds that Tetsuo is dueling Ryoga Kamishiro , the " Shark " . Shark Summons " Big Jaws " and uses it with " Skull Kraken " to Xyz Summon " Submarine Tender Aero Shark " . He explains some of the rules of Xyz Summoning as he does so . He declares an attack with " Submerine Tender Aero Shark " , which drops Tetsuo ' s Life Points to 0 . Shark and his cronies start to mock Tetsuo , who is comforted by Yuma and Kotori . Yuma starts yelling at Shark , but he walks away without looking back , while his cronies mock Yuma stating that Shark is so good as a duelist he won the national tournament . However Yuma says he doesn ' t care and that he ' s going to be the duel champion . He quickly regrets it as Shark turns back and yells that become the duel champion isn ' t something you just say . Shark snatches Yuma ' s artifact and his cronies restrain Yuma , who tries taking it back . Shark then snaps the artifact in two and tosses it back to Yuma . Shark says he will give back Tetsuo ' s deck if Yuma beats him in a duel but if he wins he ' ll take Yuma ' s deck too . Shark tells Yuma to meet on sunday at the park to have their duel . Later outside , Yuma holds one portion of the artifact and weeps over what happened , while Kotori tries to comfort him . They are later joined by Tetsuo who tries to convince Yuma not to duel Shark as Yuma couldn ' t beat him there is no way Yuma can defeat Shark . Yuma refuses telling Tetsuo not to get the wrong idea , he isn ' t doing it for him , he ' s doing it because Shark broke something important to him right in front of him and that his parents wouldn ' t runaway from a fight . Tetsuo hands the other part of the artifact to Yuma and says not to get the wrong idea either as he just saw it laying on the floor . Afterwards he parts ways . At home , Yuma changes out of his school uniform and makes a few changes to his Deck . Before he leaves again , he is given a package from Haru . Yuma gives a thumbs up and leaves .
