Kyoji Yagumo watches in horror as Shark destroys " , and Shark declares that the way of the lone shark is to hit back when they ' re hit . Yagumo warns Shark not to mess with him , and he activates the effect of his Field Spell Card , " Soul Arena " as a whirlwind of darkness surrounds him . Shark is shocked at Yagumo ' s bloodthirst , which he describes as inhuman . Yagumo explains that the effect of " Soul Arena " allows him to discard his hand since a Rank 8 or higher " Number " was destroyed , and then Summon as many " Numbers " as possible in his Extra Deck . Shark protests that Yagumo can ' t Summon any more " Numbers " , and Yagumo agrees with his fears ; the door to the otherworld will open and this world will be destroyed , which is what Yagumo wants . Shark watches in shock as " " , " " and " " all appear on Yagumo ' s field , and Luna screams that they ' ll activate the device . Shark yells Luna ' s name as energy erupts from the spherical device between the Red and Blue Towers . Most of Akari ' s newscreens fizzle out , and Akari asks what happened . To her shock she sees Yuma leaning over Kaito , and she wonders why they ' re at the Duel Arena given how many times she ' s told Yuma not to Duel . She hears Haru muse that boys will be boys , and she warns Akari that it appears that Kazuma ' s message is coming true . Akari tells her grandmother that she is going out for a bit . She heads out on her motorcycle to see a portal opening above the Duel Towers , and she gasps that Yuma and the others are right under it . She wonders if this is what her father was talking about . Akari remembers sitting on the roof of their house with her father , who described it as relaxing despite feeling like he was about to fall , like sleeping halfway up a slope . Akari comments that her father is weird . Kazuma asks Akari what she wants to be when she grows up , and Akari explains that she wants to be a journalist in order to tell people the truth about what is going on in the world . Kazuma comments that it ' s quite the grand dream . Akari asks if Kazuma has found anything on his adventures that nobody knows about yet . Kazuma replies that he has , and Akari begs him to tell her . Kazuma reaches for the sky , explaining that he discovered the Astral World . Akari asks where it is , and Kazuma admits that he doesn ' t know yet , but it ' s supported by the four elements of air , sea , land and light . He claims that it is where Duel Monsters are from , and he suggests that supposedly , the souls of the people there exist on a higher plane than theirs . Kazuma explains that he ' s going to find a door to the Astral World on Earth , and he asks Akari to look out for her grandma and Yuma if anything ever happens to him . Akari snaps at her father not to say things like that and smacks him , prompting Kazuma to warn her not to slap him or he ' ll fall . Akari reflects that her father hadn ' t been joking ; later he and her mother disappeared during one of their adventures . Just when the family had gotten over the pain of losing them , Kazuma ' s spirit appeared to her . She asked if he was back , but Kazuma explained that he couldn ' t stay long . She asked where her father had been , and Kazuma replied that he ' d found a way into the Astral World and had to tell her something . He explained that the world would son suffer a great disaster , and he warned her not to take her eyes off Yuma ' s Duels , since during that disaster , he would be the one to open a new path to save the world . He gave her the Emperor ' s Key and asked her to give it to Yuma before fading away . Akari woke up the next morning and wondered if it had all been a dream , but the presence of the Emperor ' s Key disproved that . Haru asked Akari if Kazuma visited her , and she smiled as she noted that knowing Kazuma he was likely racing around helping people . Akari asked if Kazuma visited Haru too , and Haru nodded . Akari made up her mind then that she wouldn ' t let Yuma Duel , refusing to let her brother vanish like her father despite Kazuma ' s request . She reflects in the present that Yuma still doesn ' t know how she feels . Yuma looks up at the sky to see the portal , and he asks what it is . The souls of the audience ascend into it as Yuma asks if it ' s real , and Astral asks if it is the door to the otherworld . Yuma ' s Duel Gazer suddenly rings , and his hair stands on end as he realizes that Akari is calling him . Akari immediately warns his that she ' s told him many times not to Duel , and Yuma apologizes , but he protests that they ' ve come too far to back out . He explains that they ' re going to go to another world ; probably the Astral World . Akari sadly admits that she thinks that ' s where their father is . Yuma asks why , and Akari replies that she doesn ' t know , but her father told them that a great disaster was coming , and he said that Yuma would save them , much to Yuma ' s shock . She tells Yuma that if he sees their father , to tell him that Akari called him a big jerk and then come home . Yuma reassures her that he will as his sister bursts into tears . Yuma cries again that he ' ll be back as the Duel Towers shatter and flow into the portal . Yagumo laughs madly , and declares that the wretched world will fall apart . Kotori , Tetsuo , Takashi , Tokunosuke , and Cathy are all sucked into the portal , and Tetsuo yells at them to hold on to something , but Cathy protests that there ' s no point since the entire monument is being sucked away . As Tokunosuke asks where they ' re going , Cologne floats past , screaming that she doesn ' t want to be a broken doll again . Tokunosuke spots her , and she screeches that she found him , asking why they abandoned her . Orbital 7 detects debris approaching as he holds Haruto in his arms , and he cries that they are in extreme danger . Luna gasps and she activates her pendant , surrounding them and the Numbers Club in a forcefield that deflects the debris . She reassures them that they should be okay for a while . Kotori protests that Yuma and the others are still in danger , and a large shard of rock approaches them . Yuma cries that it ' s going to hit them , but Astral shatters it with a gesture . Astral explains that this appears to be a passage to the otherworld , so his true powers have returned . Kaito wakes up , and he is surprised to see Astral looking so solid . Yuma realizes that they must be heading towards the Astral World , and they exit the passage , appearing in space above an ocean , with Earth in the distance , and the Astral World in another direction . Kaito asks where they are , and Yagumo ' s voice explains that this is an otherworld ocean . Shark looks up at Yagumo , flying with his spider legs , and he angrily asks why Yagumo dragged them here and what he is plotting . Yagumo explains that they haven ' t reached the end yet . He asks them to listen closely ; do they hear it ? To their shock , the group see what Yagumo describes as a black hole from another world . Yagumo explains that the Astral World and their world float in two oceans , and son the two worlds will be pulled into the hole and annihilate each other .
