Kite recalls watching Quinton leave years ago , and wonders why he did . At the Duel Coaster Stadium , Bronk wonders what ' s going on , as they haven ' t shown any Duel s in a while . He wonders if Yuma is alright and Caswell adds that something ' s not right here . Orbital 7 suddenly speeds through the air , flying towards the entrance to the Duel Coaster ' s underground section . He says he can ' t wait for Kite anymore - he needs to go to him now , even if Kite will turn him to scrap for following . Yuma speeds along on his Duel Coaster , having no clue where ' s he going . Tori tells him to slow down , but Yuma says he has to find an opponent . Astral says if he isn ' t careful and Tori finishes by saying they ' ll hit a trap again . There ' s an explosion overhead and Yuma wonders if someone else hit a trap . Orbital 7 comes flying through the air out of the explosion and lands on the coaster between Yuma and Tori . He calls them " the crazy duo " . Tori asks if he ' s alright , and Orbital calls her " the scary girl " . Tori angrily grabs him and threatens to throw him off the coaster ( in the dub , Tori instead threatens to rearrange Orbital ' s wiring ) . He says he needs to get to Kite and Yuma remembers Dextra falling to Vetrix for Kite ' s sake . Yuma says he has something to tell Kite and tells Orbital to lead them to him . Orbital agrees . Kite and Quinton have arrived at the Space Field and both appear on the flat surface of the space station ' s roof . Quinton says he knew the day where they would fight would come . Quinton remembers watching Hart and thinks the day he found out the truth , his heart became surrounded by hatred and revenge . Kite says he will make Quinton pay for hurting Hart . They begin the Duel , with Quinton saying he ' ll take the first turn . He Normal Summon s " Planet Pathfinder " and Special Summon s " Solar Wind Jammer " from his hand via its own effect by halving its ATK . He activate s " Tannhauser Gate " and explains that it lets him change the Level s of two his monsters to their combined total . He changes the Level 4 " Planet Pathfinder " and the Level 5 " Solar Wind Jammer " to Level 9 . Kite says he has two Level 9 monsters . Quinton overlays them to Xyz Summon " " in Attack Position . The monster fails to appear though and Kite asks where it is . Quinton ignores him and explains the effect of the Duel Field , " Space Field " . When a player Xyz Summons , they draw a card . Quinton Set s a card and ends his turn , with Kite again questioning where his monster is . Quinton asks him what ' s wrong and tells him it ' s his turn . Kite thinks that even if the monster can ' t be seen , its still there as a Summon was declared . He Normal Summons " Photon Delta Wing " . He orders it to attack with " Photon Missile " . The missiles miss Quinton and are absorbed by a behind him . Quinton apologizes , saying his attacks can ' t reach him . He asks if that will be all and begins his turn . Quinton orders " Dyson Sphere " to attack " Delta Wing " . A appears behind him , which blasts " Delta Wing " with spears of light , destroy ing it and bringing Kite down to 3000 Life Points . Kite asks what ' s going on here and Quinton says he knew Kite wouldn ' t understand - Quinton ' s Dueling has gone far beyond his imagination . Yuma ' s Duel Coaster appears in the air and Tori asks if this is the Space Field , which Astral confirms . Orbital says he ' s confirmed the signal from Kite ' s D - Pad and they fly towards the space station . Tori asks why he ' s speeding up and Yuma says the coaster ' s controls aren ' t responding to him . They crash between Kite and Quinton , with Tori calling Yuma an idiot and Orbital asking Kite if he ' s alright . Yuma gets up and says he has something he needs to tell Kite . He explains that Dextra was defeated by Vetrix . Kite ' s eyes widen and Yuma continues that Dextra fought Vetrix for him . Kite responds that he doesn ' t care . Yuma grabs Kite by the collar and Quinton calls out to Yuma . He calls him Kazuma ' s son and says that everyone has now gathered here - it must be fate . Yuma says he has something to ask Quinton - where is his father ? Quinton says he ' ll tell them everyone he knows before they continue the Duel . Kite says he has no time to listen to such a story and asks to continue their Duel . Quinton says the story is relevant to him too and that the Duel can wait . He asks if Kite didn ' t wonder why Quinton ' s family suddenly appeared in the World Duel Carnival , why they targeted Hart and why they were trying to take revenge against their father - Dr . Faker . Yuma is surprised to hear that Faker is Kite ' s father and wishes to know why they want revenge . Quinton explains that five years earlier , Kite ' s father , Faker , and Quinton ' s own father , Byron Arclight , were conducting research about opening the doorway to other dimensions . They worked from Heartland Tower . Faker says they found dimensional distortions all around the world , but he can ' t pinpoint their exact location . He angrily slams his hands onto his keyboard . Byron appears behind him with a drink and tells him drink it and calm down a bit . Faker turns and knocks the drink from Byron ' s hands , with the mug falling to the floor and shattering . He says he has no time to do that - he must find the door to the other dimensions . Byron tells him there is one other person attempting to find that doorway . Quinton is standing at another console and he tells him to bring up that person ' s image , calling Quinton " Chris " . Byron says he ' s an interesting man - an adventurer named Kazuma Tsukumo . Kazuma sits on a rock in the desert , watching the sunset . He says it ' s peaceful and that no one should bother him here . A helicopter appears overhead and he guesses he was wrong . Kazuma enters Heartland Tower with Chris and complements the amazing equipment they have . Byron thanks him for coming so quickly and shakes his hand , introducing himself as Byron Arclight . Kazuma says they have a gravity wave map and an electromagnetic wave map , both very impressive . Faker yells he has no time to be flattered - he analyzed all the distortions and still can ' t find it - something has to be missing . Byron asks for Kazuma ' s opinion about the door ' s location . Kazuma steps forward and says finding the door will change mankind ' s history and make those that discover it rich and famous . Faker says he has no need for either of those things , he simply must find the door . Kazuma smiles and says he feels relieved to hear that . Kazuma says what interests him about the door is its potential for a real adventure . Byron asks if that was a test , then . Faker tells Kazuma to look at the electromagnetic wave map . He explains that after the appearance of the doorway , he found odd phenomenons in twenty - one places around the world . He says he was positive he could determine the next place the door would appear if he analyzed those places . Kazuma calls it the twenty - first dimensional equation and Faker says there is only one more step . Kazuma says he ' s missing something . Faker says that ' s impossible , but Kazuma clarifies that there are not only twenty - one locations . He says that by just sitting around in a lab , they ' ve missed some things . He reveals there are twenty - three locations , meaning there are two more . Kazuma says the true answer is the twenty - third dimensional equation . Quinton says that by analyzing that new data , they pinpointed the location and headed there . Faker tells the rest to stay behind , just he , Byron and Kazuma will go . Byron tells Chris it will be fine . In the present , Quinton says that what he saw ends there . From here on is the story his father told him . Guided by Kazuma , they climbed down into the valley . While making camp one night , Byron asks if they ' ll really make it and Kazuma responds by explaining " kattobingu " . He shows Byron a picture of his family . Kazuma says his son loves Dueling and Byron says his own son is the same way and says that he has three sons , also telling him that Faker has two . Kazuma asks just what is it that Faker is after . Byron says he doesn ' t know , but he does know that Faker is a true genius . He says that no matter what the reason is , he wants to help with Faker ' s work . Kazuma says that Faker must be happy to have a friend like him . In his tent , Faker types on his console . He translates some runes and reads them saying that " by offering two souls , a great doorway will appear " ( in the dub , he says " Deliver two souls for mysteries untold " ) . He smiles . Q Quinton explains that after three days , they finally arrived . Byron asks if its ruins of an ancient civilization and Faker sees three markings on the ground . He says this is the place for sure . He steps on a floor slab with an inscription on it . The inscription glows red and the door slams shut . A giant slab falls from the ceiling . Kazuma jumps , pushing Faker out of the way in time . Kazuma tells Byron not to move and says that traps must have been set to deter intruders . Later , they descend some stairs , with Kazuma saying that up to now has been child ' s play . They must use all of their bravery and knowledge from this point on . Byron asks if Faker is alright , with Faker saying he ' s fine . He lags behind the other two a bit though . Bryon and Kazuma reach the very top of a set of stairs , which just leads to the top of a pillar . Kazuma says its a dead - end , but there must be something here . The runes below them glow red and electricity pulses through their bodies as they turn red as well . Below them , Faker says that the moment has come . He says he feels sorry for them and Byron asks what ' s he ' s doing . Faker explains that the runes below them say " by offering two souls , a great door will appear ( " Deliver two souls for mysteries untold " in the dub ) . Byron asks if he ' s trying to use them as sacrifices and Faker says he must find the door at any cost . Kazuma asks if Byron wasn ' t his friend . Faker says that friends are useless . The stairs collapse and Faker says that if Byron is his friend , he should be happy to to be sacrificed and that it ' s the best an average person like him could hope for . The pillar collapses and they fall towards a portal . Kazuma barely hangs on and grabs Byron ' s hand , yelling " kattobingu " . Byron tells him to let go of him , as if he doesn ' t , Kazuma will fall too . Kazuma says he ' s heard it said that if Duel someone , you become friends - and to him adventuring is his Dueling . Faker tells them to disappear and the piece of rock that Kazuma is hanging on to falls . They both fall towards the portal , with Byron yelling he won ' t forget this . In the present , Yuma says that was his father ' s last adventure then . Astral compares the sacrifice to Xyz Summoning . Quinton says his own father returned though . He has wandered through the other world , with only revenge on his mind . Because of that , he had changed . His father is currently known as Vetrix . Everyone is surprised . Quinton says that the true culprit is Faker - and Quinton will make him pay . Kite says he has only Hart , he has no interest in what Faker does . He says they ' ll continue the Duel now and tells Yuma to move out of the way . Kite Special Summons " Photon Thrasher " in Attack Position , explaining he can do so when he control s no monster s . He Normal Summons " Photon Pirate " and explains that it can banish a " Photon " monster in his Graveyard to increase its ATK by 1000 until the End Phase . He banishes " Delta Wing " to increase the ATK of " Pirate " to 2000 . Quinton says there are two monsters with 2000 or more ATK and Yuma says Kite ' s ace card is coming . Kite Tribute s " Thrasher " and " Pirate " to Tribute Summon " Galaxy - Eyes Photon Dragon " in Attack Position . Kite remembers that last turn , he took 1000 damage when " Delta Wing " was destroyed by battle with Quinton ' s " Dyson Sphere " . So that means that Quinton ' s " Number 9 " must have 2800 ATK , since " Delta Wing " had 1800 ( 1800 ATK on " Delta Wing " + 1000 Battle Damage = 2800 ATK on " Dyson Sphere " ) . He tells " Galaxy - Eyes " to attack with " Photon Stream of Destruction " , but Quinton says he ' s foolish . The blast goes through Quinton and he takes no damage . He says he ' ll show Kite his " Number " now . Bright light streams out from the sun , blinding everyone . A black object appears from behind the sun , which is quickly engulfed by a tube in the center of the object . Two small satellites float around it . Quinton says its the gigantic monster that even consumes the sun - " Number 9 : Dyson Sphere " . Quinton claims that no matter what the monster is , " Dyson Sphere " cannot be defeated .
