In Shark ' s hideout , Luna sees the event on - screen , and when she realizes what the monument in between the twin towers of Heartland New Tower is she can barely believe it . In the stands , Tokunosuke is confused , asking someone to tell him what is going on . Tetsuo suddenly gets a message on his Duel Gazer from Yuma , attracting Kotori ' s attention , and he tells Yuma that they ' re on it . Outside Heartland , Cologne complains about Yuma leaving her behind and she wonders where he went . Something suddenly speeds past her ; it ' s Luna , hidden under her cloak . Recognizing Luna from her time with Dr . Faker , Cologne tries to play dead , causing them both to sweatdrop . Luna picks Cologne up , recognizing her and commenting that this is perfect timing . She asks if Cologne is with Yuma and if she recognizes the monument from Dr . Faker ' s lab . Cologne panics , protesting that she ' s just a doll that looks like Princess Cologne . The Number Club show up , blowing Cologne ' s cover , and Kotori asks who Luna is . Luna introduces herself , explaining that she is Ryoga ' s partner . Kotori protests that Shark is on the Dueling field now , and Luna replies that she knows , stating that there is no time . She needs their help to stop the monument . Takashi asks what is wrong with it , and Luna explains that it opens a door to another world . If activated , Heartland City faces annihilation . Luna states that Kyoji Yagumo is plotting something terrible . Kotori protests that they have to find Haruto , and Tetsuo explains that they got a call from Yuma , asking them to find Haruto as Yagumo was holding him hostage , and that was why Kaito had switched to Yagumo ' s side . Luna immediately suggests that they split up and find him . Tetsuo takes charge , ordering Kotori , Cathy and Takashi to go and find Haruto , while the rest of them will stop that device . The Numbers Club move out , leaving Luna and Cologne standing . Yuma deploys his D - Pad , asking if he will be facing Kaito and Shark facing Yagumo in a double Duel . Astral wonders if Kyoji Yagumo is planning something , and Yuma asks what it could be . Astral explains that right now all the " Numbers " are in these two arenas , and Yuma realizes that Yagumo wants to settle it all right there and now . Astral nods in agreement and comments that it would appear that way ; this is the final battle in the Numbers War . Kaito meanwhile is thinking to himself that whatever the reason , he , Yuma Tsukumo , and Astral have a score to settle . Yuma protests that he can ' t believe they ' re fighting Kaito , but Astral reminds him that they have no choice . Kaito tells Yuma , " let ' s do this " , and he engages Photon Change and both players ready their D - Pads , Yuma his Duel Gazer , and Kaito his tattoo with a declaration of " Duel ! " The Heartland doppelganger announces the beginning of the Duel in Red Stadium and Kaito goes first , declaring his turn and drawing a card . He Summons " Photon Advancer " with 1000 ATK and then Special Summon s another from his hand since he already controls a " Photon Advancer " . Then he activates their effects , making the ATK of each " Photon Advancer " he controls the sum of the two , and thus both " Photon Advancers " rise to 2000 ATK . Astral notes the two monsters with at least 2000 ATK each as Kaito Releases both monsters , chanting " Descend , incarnation of light ! Galaxy - Eyes Photon Dragon ! " Yuma is shocked to see " Galaxy - Eyes " is already in play , as Kaito ends his turn . Yuma declares his turn and draws . Astral advises Yuma to by them some time so that Tetsuo and the others can change the situation . Yuma agrees , and Summons " Gogogo Dexia " , which bursts out of the ground with zero ATK . Kaito is surprised to see a zero ATK monster , and Yuma activates a Spell Card , claiming that there ' s more to his monster than that . " Golem ' s Clap " allows him to Special Summon " Gogogo Aristera " from his hand , another zero ATK monster . Then he activates their effects , switching them into Defense Position . The two hands clap as they stand with 2200 DEF each , as Yuma explains that his opponent can no longer attack EARTH monsters . Yuma Set s a card and ends his turn . Kaito notes that they ' re preventing him from attacking with a monster effect , and Yuma replies that even " Galaxy - Eyes " can ' t attack now , and this will prevent it from using its exclusion effect too . Kaito muses that he sees that they came prepared to fight " Galaxy - Eyes " , but he vows to win the Duel for Haruto ' s sake . He equips to Equip Spell Card s to " Galaxy - Eyes " , " Galaxy Shot " and " Galaxy Barrier " . Yuma states that it ' s pointless to beef " Galaxy - Eyes " up if he can ' t attack , and Kaito asks if Yuma is sure about that . He declares that this is a trump card that he ' s never shown anyone , and he overlays " Galaxy - Eyes " and the two Equip Cards . Astral and Yuma are shocked , and Yuma asks if that is even possible . Kaito chants , " At the end of the Milky Way ' s light , a new world opens ! Descend , scion of divinity ! Armored Xyz Summon ! Come forth , new incarnation of light ! Galaxy - Eyes Full Armor Photon Dragon ! " Astral gasps that it ' s a new Xyz Monster . Featured Duel : Yuma Tsukumo vs . Kaito Tenjo .
