Cathy cheers Yuma up , but when she was going to say that if he defeated Cologne she ' d be able to keep with the attire , the others stare her , and she instead says that she will return it . Cologne then activates the effect of the Field Spell Card " Doll House " , as Astral confirms that the field they are in indeed had a kind of special effect . They notice the destroyed dolls came back with parts of another of them added to their bodies , and Cologne says that if Yuma " breaks " her dolls , Grandpa Demetto will fix them for her . Tokunosuke then notices a craftsman sitting on the doll house from where Cologne showed up , and they realize that man is Demetto , but comment about his bad appearance , making Cologne scream that Grandpa Demetto is always doing his best to fix the dolls , and that she won ' t allow them to treat him as a fool . Astral tells Yuma to keep his concentration , as she now has three Level 6 monster , but they get surprised seeing that instead of Overlaying them , she sent her own monsters to be destroyed by Yuma ' s " Zubaba Knight " , taking considerable damage .

Yuma , the Numbers Club and Cologne then run towards an iron bridge in order to escape from the Heartland Theme Park , but the exit is locked , and Kaito Tenjo and Orbital 7 appear . Kaito challenges Yuma to a Duel in order to obtain his " Numbers " , but Mr . Heartland shows up from the upper stairs , interrupting them . Mr . Heartland smiles and orders Kaito to defeat the messenger from the Astral World in front of him . However , Kaito says that he didn ' t become a Numbers Hunter because of his orders , and triggers Orbital 7 ' s self - explode mechanism , kicking him towards Yuma ' s gang , which destroys part of the bridge . This makes Yuma and his friends fall in the water under them , which allow them to escape . Cologne explains to the gang that Kite has became a Numbers Hunter to protect his little brother , who is ill . Later , Yuma and the members of the Numbers Club gather in Cathy ' s house .

However , she just turns around and says that she likes Yuma ' s house better , and that she prefers love to money . Tetsuo then asks Cathy what she wanted to show them .

Faker , who plans on using the hidden powers of the " Numbers " to destroy the Astral World ; However , it is linked to this world . So , if the Astral World dies , this one will die as well . Kotori asks if that ' s for real , and Yuma answers saying that Astral doesn ' t lie - in fact , he can ' t lie . Cathy asks what is that hidden power of the " Numbers " , but Astral haven ' t regained that much memory yet . Takashi asks if Dr . Faker knows both worlds are connected , and Cologne says that he brought her to life , but that he is a really scary scientist , and that she wouldn ' t put it past him . Takashi and Tokunosuke get scared on how he knows about that fact but still wants to destroy the Astral World , and on how a man like that is collecting the " Numbers " . Yuma says that they have to get the " Numbers " first to stop Dr . Faker ' s plans , and Tetsuo then deduces the fate of the world is riding on this . Then , everyone , except for Tokunosuke , gets spirited up and say that they will keep on collecting the " Numbers " , and that the Numbers Club will protect the world . Cologne helped Yuma and Astral investigate Shark ' s past , as well as why he started hunting " Numbers " . Deck .
