Under the [[UTS officeMain Office]], [[London Kirishima]] comments that of course it would be [[Yuamu Ohdo|Yuamu]] to catch him and [[Netsuzo Shinjitsu|Netsuzo]] sneaking in, and Yuamu observes that once [[Rovian Kirishima|Rovian]] learned of the [[Space Treasure]] she must have realized it would require a considerable amount of energy to excavate, envisioning Rovian cutting her way through the ceiling of the [[Alien Residential Area]] and struggling under the abnormal gravity, which Yuamu deduces Rovian managed to use as an energy source. As Rovian is shown using a [[Rush Battler]] to enable [[Menjaburo Omori|Menjaburo]] to move while London and [[Yuna Goha|Yuna]] look on, Yuamu adds that Rovian had the aliens in the Residential Area [[Yu-Gi-Oh! Rush Duel|Rush Duel]] to collect that energy under the guise of "[[Duel Power (GO RUSH!!)|Duel Power]]". Then once they had enough and had tracked down the Space Treasure, London used [[UTS]] to steal the treasure from Rovian. London asks if they're calling him a thief and [[Fisher Sukai|Naval Number 81]] confirms they are, apologizing for being late, while Netsuzo is shocked to see the Informant. London lightly comments they can't escape, much to Netsuzo's dismay, but then London tells Yuamu her thinking was a little off as he steps towards the Space Treasure and circle of golden light appears beneath him, causing a slot to open in the Space Treasure that he pours dozens of Rush Battlers into, and the golden lines on the Space Treasure light up, much to Yuamu's shock.

Then a massive crash begins to shake the earth and as everyone asks what's happening, Tazaki notices the buildings rising around them - but everyone is sinking as the yard between the buildings sinks on a hydraulic plate and moves under the ground above it to make room for a massive rectangular passage, and the Space Treasure rises from it - a green spaceship marked with gold. Yuhi doesn't recognize it, but Yuna does, protesting this was what Rovian was supposed to be after before recognizing London and Netsuzo in the cockpit. Bochi and Manya recognize Kirishima London as he waves, catching Yuhi and Manabu's attention, and [[Nyandestar]] runs off as Manabu calls after her. Rovian admits she knew London was sneaking behind her back but warns him that he's really done it now as the shadow of the Space Treasure rises above them, and Nyandestar leaps onto the ground, then toward the Space Treasure, only to miss and plummet to the ground, though fortunately Manabu catches her. As he asks if she's all right, Nyandestar looks up at the retreating ship and Yuna seethes over Netsuzo Shinjitsu betraying them as well while the ground returns to normal, screaming that she's angrier than the 14th or 13th dimension.

In the [[MIK headquarters]], [[Ranran Nanahoshi|Ranran]] is shocked that a spaceship took off from [[Mutsuba Town]], while at [[EX6]], [[Tell Kawai|TellKawai]] explains to [[Asaka Mutsuba|Asaka]] that some aliens left a spaceship here long ago and this must be it. Ranran wonders if this was Rovian's true goal, noting that now they have this and [[The☆Lugh's spaceship|an unidentified object]] approaching [[Earth (planet)|Earth]] from outside the solar system and wondering what will happen.

Meanwhile London and Netsuzo are panicking as the ship rises beneath the Space Treasure, London protesting he didn't know about this. As the massive spaceship leaves the atmosphere, Yuamu thinks to herself there was no way their family's Space Treasure could have just been the small ship before losing her grip from exhaustion and falling, much to the horror of Naval Number 81 and London. Fortunately Yuhi catches her, and Yuamu awakens to find herself lying on top of her twin brother atop several mattresses in one of the buckets of Asaka's excavator, Asaka warning them the contraption is already somewhat unstable and telling them not to fall off as Tell Kawai sighs in relief. Yuhi groans in pain and Yuamu thanks him, the twins laughing as London sighs in relief. Netsuzo notices the alert from the back door has vanished, so London declares full speed ahead and flies the small ship out of the energy shield covering Mutsuba Town and into space.
