The chapter starts showing a flashback of one year prior to the present day , before the Heartland City Duel Tournament finals . Kyoji Yagumo runs flustered , and clashes with Shark , who was standing in the hall . Both fall , as the cards Kyoji was holding spread off in the ground . Shark yells at Kyoji asking what he is doing , as the finals was going to start at any second , when he notes the Deck spread on the ground wasn ' t Kyoji ' s . He asks Kyoji whose Deck is that . Kyoji doesn ' t answer , and runs away , as a finalist of the tournament arrives with a crowd of people , yelling that was his stolen Deck , and asks Shark if he was the one who took it . Shark tells to himself that Kyoji is warped as he is , and that he represents the children ' s hopes and dreams , so he can ' t let him be tarnished . After hesitating a bit , Shark confirms that he was the one who stole the Deck . Securities from the tournament then escort him , as Luna watches from away . Back to the present , at Cathy ' s house , Yuma says he wants to know more about Shark , as he thinks there is a reason Shark is getting involved with the " Number s " . Kotori says that there is one - he was already possessed by a " Numbers " card before . Yuma replies that exactly because Shark knows how scary they can be , he wonders why is he going back for more . Tetsuo explains that he heard Shark got banned from the Duel ing world a year ago . Astral suggests them to look into Shark ' s past , as they may learn something , and Yuma agrees . Cathy declares that couldn ' t be easier , and orders the employees to double research Shark . Takashi notes they find a ton of data in no time , but all they find are about real sharks , not the person . Laughing , Yuma says he wants to know about the guy , Ryoga Kamishiro , aka Shark , not about fishes . As the employees research about Ryoga , the gang is amazed at how many prizes he won at tournaments , and at how he was an awesome Duelist , not some punk . Yuma looks sad to a picture of him , and wonders if he was so awesome , then why was he banned . Later , at Yuma ' s house , Yuma throws some newspapers with Dueling news on the floor , yelling that that ' s no use , and that even with all that material he got no clue . Astral says there must be a lead somewhere though , as Cologne shows up with a detective costume , agreeing with Astral . Yuma asks her why she is so exited about that , to which she answers saying that it ' s boring to be always at his room , and that that was better than crossword puzzles . Astral comments he has noticed something that all those articles have in common , as Cologne praises him and says she did as well . Yuma asks what it is , and they point out a spot of an article , which read " Duel Monsters Regional Cup Champion : Kyoji Yagumo " , as Astral reads loud " Kyoji Yagumo " . Yuma asks who is he , but Astral says he has no idea , and Cologne explains that even though he must be involved somehow . Astral tells Yuma to take note of who placed second in every tournament that listed his name . As Yuma reads the rest of the article he was holding , which showed " 2nd Place : Ryoga Kamishiro " , Astral says that ' s not the only one - Shark placed second in every tournament . Meanwhile , Shark and Luna stand in the top of a in - construction building . Shark says thanks to Luna and to , Shark saw some interesting things . Luna says that Yuma Tsukumo , Kaito Tenjo and Astral - all the players are in place , but Ryoga corrects her saying that all except for " him " . He also adds that if all Luna said was true , he must know the truth - that ' s why he decided to help her destroy the " Numbers " . Luna says that ' s Kyoji Yagumo , the one who changed Shark ' s fate , as Shark tells to himself that is he is going to make the wrong move , he must stop him . A flashback of several years ago is shown . At an orphanage , many kids surround Kyoji Yagumo on the yard , happy , as Kyoji shows them a " Duel Monsters " card . Seeing that , Shark , who was leaving the house , turns to the other way . Kyoji notices him , and walks to Ryoga with some kids , who is sit holding his " Submarine Tender Aero Shark " card . Kyoji tells him he should Duel with them sometime . He also adds that Dueling was going to change their lives , and that he wanted to become a Duel champion and make everybody happy . However , Shark notes one of the kids that came with Kyoji is afraid of him , and hides behind Kyoji . Shark then leaves , saying that he ' s got no use for guys like Kyoji . In the present , Shark tells to himself Kyoji wasn ' t warped like him - he was everyone ' s hopes , but Shark himself was just bad news ; Somehow , they got those reputations , but that didn ' t bother Shark . He also adds that the children of the orphanage found the hopes and dreams they needed them in Kyoji Yagumo , and that he was certain Kyoji would achieve his dream and make everyone happy . The flashback then advances in time , showing a final match of a Dueling tournament , disputed between Shark and Kyoji . The MC announces Kyoji as the champion , but Kyoji asks Shark why he didn ' t activate his face - down card at the end of the Duel , as Shark was leaving the arena . Shark says that Kyoji represented everyone ' s hopes and dreams , but that he was just a shadow . Kyoji stands in the arena and watches as Shark leaves , with a sad expression on his face . Back to the present , Luna states that she knew right away what happened - Kyoji Yagumo dropped the stolen Deck , and Shark took his crime upon himself . During the next day , the Numbers Club go to the orphanage Shark and Kyoji were raised . There , they learn neither of them had families . Yuma notes a photo framed among others , which showed Kyoji smiling and holding a trophy , other kids surrounding him , and Shark , indifferent . Kotori , Tetsuo and Takashi explain that they asked around and learned that Kyoji was a hero at that place , but on the other hand , Shark . . . Astral comments Kyoji and Shark were like light and shadow . Yuma asks if they didn ' t get along , and Tetsuo answers saying that the teacher said Shark might have actually liked Kyoji . Kotori adds that she said Shark sulked a lot , but he looked after the small children and didn ' t tell lies or play tricks . Yuma looks to an article on a newspaper showing Shark being disqualified from the Heartland Due Tournament for cheating , and wonders when he did that . Tokunosuke said that every story has a back - story . Cathy and Tetsuo comment that Shark disappeared from public Dueling after that , and that witnesses spotted Kyoji at the scene , but Shark insisted Kyoji had nothing to do with it . Astral says that if his hypothesis is correct , Shark may have covered for Kyoji . Yuma and the others are surprised at it , as Takashi comments that in other words , Shark took the fall for Kyoji . Astral says that Shark was actually a kind person , but that his reputation was horrible , whilst by contrast , Kyoji was a hero who gave those children hope . As Yuma sees the children play through the window , he notes how as Shark didn ' t want the children to lose hope , he did such a thing . Elsewhere , Shark , angry , says that Kyoji was their hope , and wonders why he did that . Meanwhile , Dr . Faker learns from Mr . Heartland that Luna has betrayed them , and calls her a traitor . Mr . Heartland also tells him that she has made a Duelist called Ryoga Kamishiro her Number Hunter , and that it appears that she wants to eradicate the " Numbers " , and that could be trouble . Dr . Faker is surprised , but quickly smiles , telling him not to worry , because as the " Numbers " are cards from another world , Luna wouldn ' t be able to destroy them easily ; besides , it ' s impossible to defeat a " Numbers " without another " Numbers " . But yells that defiance must be punished though , and orders Mr . Heartland to get rid of Luna and Shark . Mr . Heartland tells him that he understands , and for that very reason , he has found a new Numbers Hunter , and says that unlike Kaito , this one would do as they wish . As the boy enters the room , Dr . Faker asks him his name . He introduces himself as Kyoji Yagumo . Featured cards . The following cards appeared in this chapter . No cards debuted here .
