Allen reassured her that they hadn ' t lost yet , and he Xyz Summon ed " Heavy Armored Train Ironwolf " and used its effect to let it attack directly but the Tyler sisters revealed that the effect of " Liger " would negate the attack . Sayaka reminded Allen that he could use the effect of " Cheer Girl " to draw a card , and Allen drew " Limiter Removal " and immediately attacked . Grace used Amazoness Substitution to switch the attack to Gloria ' s " Amazoness Swords Woman " , and Allen used " Limiter Removal " to double the ATK of " Iron Wolf " . Grace used the effect of " Swords Woman " to reflect the damage back to him , but Sayaka saved him with " Fairy Rail " , turning the damage into ATK for " Cheer Girl " . Sayaka told Allen to use " Fairy Cheer Girl " for the next attack and they were able to turn the Duel around .

A squad brought by Duel Academy Commander - in - chief Aster Phoenix started to surround them , but Kite defeated them , allowing everyone to escape while Yuya Dueled Aster . They reached their hideout , and Allen and Kite returned with their Resistance comrades to assist Yuya , arriving just as Mamoru Noro ordered the Duel Academy soldiers to attack Yuya and the defected Aster and the Tyler sisters . Allen explained that Kite had brought everyone to help him and that Shay was being looked after by the others .

Back at the Duel Sanctuary , Allen expressed his concern over their decision to let Aster and his former Duel Academy squad come to their hideout and help them . He was surprised when Kite admitted his mistakes after seeing Aster do the same , despite Allen reminding Kite that Duel Academy had sealed his family into cards . He listened to Yuto , who was speaking through Yuya , assure Kite that he was showing bravery by admitting his own mistakes and enduring the pain of losing his family and friends . To Allen ' s surprise , Aster revealed that there was a way to restore the people who had been sealed into cards , but they would have to retrieve the cards from Duel Academy .

A dimensional rift opened in the sky , and Allen wondered what the massive dragon that he could see in it was . Another rift opened and started to pull people inside , and Allen told Sayaka to hurry but she was distracted the sight of Shay and Kite Dueling on the other side of the rift . A rift opened in front of her , and Allen tried to save her but they were sucked into it and transported to the Fusion Dimension . They woke to find themselves present as Shay and Kite Dueled an opponent who they called Yuto and Yuya . Allen was amazed when Shay and Kite used " Rank - Up - Magic Limitover Force " to Rank - Up their monsters without knowing what the other had in their hand . Kite used " Rank - Up Gravity " to force his opponent ' s monsters to attack and banish them if they didn ' t , a strategy Allen thought perfect since Shay and Kite ' s monsters had the higher ATK . However , their opponent used the effect of his " Supreme King Servant Dragon Dark Rebellion " to reduce the ATK of their monsters to zero . Before Allen and Sayaka could see anymore , another rift opened , transporting them to another dimension . Allen and Sayaka found themselves outside You Show Duel School , as the portion of Paradise City that they were in was merged with the other dimensions . They noticed an island passing with several of their Resistance comrades who had been sealed into cards , and they realized that their comrades had been freed .

Allen and Sayaka were happy when Yuya brought out " Dark Rebellion Xyz Dragon " . Allen applauded Yuya ' s victory and also watched his Duel with Declan . When Yuya ' s " Starving Venom Fusion Dragon " was attacked by Declan ' s " D / D / D Doom King Armageddon " , Allen encouraged Yuya to use the Rollerboots , but to his surprise , Yuya instead flew up with " Starving Venom " to grab an Action Card . He was amazed when Yuya used the effect of " Odd - Eyes Venom Dragon " effect to increase its ATK by the combined ATK of Declan ' s monsters . Allen was surprised when he thought Yuya defeated Declan and noted how Yuya was smiling after he used the effect of " Performapal Five - Rainbow Magician " to lower their monsters ATK to 0 . He watched Yuya and Declan gather Action Cards to in order for one of them to win the Duel first due to " Five - Rainbow Magician " . Allen was happy that Yuya won and was sent to the Pendulum Dimension by Ray Akaba to witness her revival as Zuzu Boyle . Deck . Allen uses a " Railway " Deck based around power tactics .
