Then he sets a card . Astral is scared that if he has another monster with 2000 ATK or more , Kite will summon Galaxy - Eyes Photon Dragon and win . So he draws a card and summons Gogogo Giant and brings back Gogogo Golem in Defense Mode and also changes Gogogo Giant to Defense Mode , activates Double Defender and sets a card .

Yuma keeps trying to open the door but it refuses to open and because of that , he gives up hope , but Tori walks up to him and slaps and yells at him for that ( Tori slapping Yuma is cut in the dub ; instead , she actually helps Yuma open the door and then the others do so ) , they managed to open the door thinking they ' re very strong but Yuma ' s Duel Gazer rings and it ' s Mr . Kay saying he used the virus to open the door . The computer systems have been hacked so then Orbital 7 looks at the security camera and sees Yuma breaking into Kite ' s hideout thanks to Mr . Kay .
