Yōtarō uses Raijinmaru to track Hyuse's scent. Jin decides that his priority is to save Yōtarō, despite the fact that not assisting the defender of the Expedition Ship could lead to its destruction, which would prevent Tamakoma Second from reuniting with Replica before Yūma's eventual death.
Meanwhile, Ninomiya Unit and Kako Unit shoot down the advancing Idras. Ninomiya then takes command and orders the Attackers and Gunners to encircle them and keep them from advancing, and Snipers to descend and shoot them down. Reghindetz orders Yomi to send more Dogs to encircle them instead.
Inside Border's headquarters, Gatlin and Ratarikov reach the Expedition Ship's hangar, where they are blocked by Tachikawa, Konami, and Murakami. Gatlin prepares to face the three defenders, with Ratarikov summoning Dogs to back him up. Tachikawa informs Gatlin that the Expedition Ship was behind the door, and he would have to defeat the three of them. At that moment, Kazama uses the opportunity to launch a sneak attack with his Chameleon, cutting off Gatlin's left arm. Gatlin then activates his Trigger and replace his lost arm with a gun. The battle begins.
