As Yagumo ' s LP falls to 8900 , he angry asks Ryoga how long he ' s going to block his way . Shark tells Yagumo to wake up , asking him what the point is in destroying the world , where children pinned their hopes on Yagumo . Yagumo snarls that he loved his little brother best , and he isn ' t there anymore ; his little brother is gone . Kaito notes that Yagumo said that he killed his brother , and he asks what he meant . Yagumo pauses , before agreeing to tell them , as they ' ll probably die here anyway . Six months prior , Kyoji and Yuji had an emotional reunion , and Kyoji thought that they ' d be happy forever , but he couldn ' t have been more wrong . His brother had changed ; behind the outward sincerity of his adoring face lurked a dark shadow . With every tournament victory , his suspicion deepened as championship money disappeared and a string of big - time robberies returned . He remembers winning the Far East Tournament , and seeing Yuji cheering him on , reflected that he knew who was to blame , but he didn ' t care . Nothing else mattered as long as his brother was beside him . But the dream didn ' t last . One night his brother asked for a favor ; for Yagumo to lose the day ' s Duel . He claims that a loss and then a comeback could boost Kyoji ' s dropping popularity . He grabbed Kyoji and he reassures him that he ' ll never ask for anything again . Kyoji shook him off , asking who he was ; he grabbed him with his right hand , but Yuji was left - handed . The boy laughed , realizing that he ' d blown his cover , and he explained that a lot of money in the underground - including his - was riding on Koyji losing his Duel . Kyoji asked where his real brother was , and the impostor explained that the family that took him in went bankrupt , and his foster parents fled , leaving him behind to be taken in by an institute of delinquents . The impostor , shown by the flashback to be black - haired , admitted his surprise that Yuji resembled him , and noted that Yuji was frail and always watching Kyoji on the T . V . Having realized that Yuji was related to an incredible cash cow , he decided to take his place and strangled him . Kyoji tried to return the favor , but the sight of what appears to be his brother ' s face begging for help staved off his rage . The impostor then revealed that Yuji had begged his brother for help in his last words , noting that despite hating him , Kyoji would never be able to kill him . After all , he was his precious younger brother . Yagumo recalls that the impostor was right ; even though he had vaguely sensed that the impostor wasn ' t Yuji , he ' d tried to believe him , to love him . The impostor left , reminding Kyoji to lose for him . But then wisps of darkness appeared in his hand , and eight blank " Number s " , in addition to " " , appeared in his hand , showing him his true path - the destruction of the world . His sclera taking on their current black color , Kyoji killed the impostor with a blast of lightning , and Yagumo declares that he killed his brother with his own hands . He snaps that nothing in the world is worth believing in , so he decided to destroy it . Declaring that no - one can stop him , he draws a card , and Astral warns Yuma that it ' s coming . Yagumo activates a Spell Card , " Revenge Prison " ; when his opponent has destroyed one of his Xyz Monster s he can Special Summon it from his Graveyard for one that is one Rank higher , but he can ' t attack that turn . He Special Summons the Rank 11 " " , and Astral realizes that Yagumo is Xyz Summon ing a Rank 12 monster . Yagumo chants , " Threads that rule the false heaven ! Become a fleeting illusion and guide my disintegrating soul ! Xyz Summon ! Come forth , Number 77 ! ! " The giant spider monster appears with 4000 ATK , and Yagumo ' s opponents all observe the Rank 12 monster in shock . Yagumo activates the effect of " The Seven Sins " , detaching an Overlay Unit in order to destroy all monsters his opponent controls . " The Seven Sins " disintegrates " Bahamut Shark " with " Spider Silk Rain " , and Yagumo explains that the monsters destroyed by the effect of " The Seven Sins " are attached to it as Overlay Units , bringing it back up to one Overlay Unit . Astral notes that it means that the " Number " will never run out of them as Yagumo Set s a card and ends his turn . Yuma realizes that Yagumo will be able to annihilate his monsters as much as he wants . Kaito steps forwards , warning Yagumo that he ' s his next opponent . Yagumo tells Kaito that he must know how he feels , and Kaito agrees that he would have once , but not anymore now that he has a friend . Yuma supported Kaito when his heart was about to break , and Kaito states that he refuses to waver any longer ; he ' ll change Yagumo ' s warped future with his own hands . He declares his turn and draws , then he Summons " Galaxy Worm " , which Special Summons another copy from his Deck since he controls no other monsters . Then he activates the Spell Card , " Memory Emerge " , which increases the ATK of all monsters he controls by 200 times the number of cards in his hand for the rest of the turn . With four cards , the 1200 ATK " Galaxy Worms " rise to 2000 ATK , and Yagumo smiles , wondering if it will appear . Sure enough , Kaito Releases his two 2000 ATK monsters , chanting , " Galaxy shining in the darkness ! Become a ray of hope and live within my servant ! Descend to me ! Incarnation of light ! Galaxy - Eyes Photon Dragon ! " Declaring that his attack will shatter Yagumo ' s ambitions , Kaito has " Galaxy - Eyes " attack with " Photon Stream of Destruction " . Yuma protests that " Galaxy - Eyes " has the lower ATK , but Shark reassures him that the attack will work . Astral reminds Yuma that the effect of " Galaxy - Eyes " will banish both monsters , and gain ATK for each Overlay Unit " The Seven Sins " had . Yagumo realizes that he ' s in trouble and admits to himself that it ' s not bad from Kaito , but warns them that he ' s not letting it happen . He activates the Continuous Trap Card " Plucked Wing " , negating the attack of the Special Summoned " Galaxy - Eyes " and negating its effect . " Galaxy - Eyes ' " wings shatter and Kaito calls his monster ' s name . Yagumo comments that " Galaxy - Eyes " is useless without its wings , and he vows to feed it to " The Seven Sins " next turn . Kaito grimly Sets a card to end his turn . Yagumo declares his turn and draws , before activating the effect of " The Seven Sins " , detaching an Overlay Unit and destroying " Galaxy - Eyes " with " Spider Silk Rain " , then attaching it to " The Seven Sins " , clearing their field of monsters . He wonders who to finish off first , and Astral notes that they all have 4000 or less LP , so someone will be out if they take a direct attack . Yuma groans , asking if they can ' t do anything . Yagumo finally decides to attack Shark , and " The Seven Sins " attacks with " Genocide Spider Silk " . Kaito snaps that he won ' t let Yagumo do this , and he activates a Trap Card , " Route Change " , halving the damage and redirecting it to himself . His LP falls to 2000 , and he falls to his knees in a cloud of smoke . Shark asks Kaito why he protected him , and Kaito claims that Shark is his friend too , so of course he protected him . Shark is staggered by the admission , and he admits that he never thought he ' d hear Kaito say that . Yagumo sneers as Kaito vows that he will never force their souls into submission .
