Galopoula Expedition Force

B-Rank Wars Arc
The force is first seen in their ship discussing the general details about their mission: to cripple Border's offensive abilities. Gatlin decided to do this by destroying Border's away ship to stop border's Away Team. at the same time Hyuse escapes from the Tamakoma Branch due to Yōtarō Rindō sleeping on the job.

They sent a horde of Trion Soldiers provided by Rodochroun so Gatlin, Wen Sō, and Ratarikov can blend in and when they got close enough, Rata uses his Tunneling Trigger to go through the walls of Border to reach the ship while Reghindetz and Koskero served as a distraction outside of Border. The three members inside of Border are attacked by Jin and Nasu Squad, but they manage to continue unharmed, though Wen Sō must stay to fight Nasu Squad. Using Servitora and impersonation tactics, she makes progress, but Nasu Squad, with the help of Kikuchihara, defeats her.

Meanwhile, Miwa Squad finds Koskero. Koskero uses Nikokyra to dull his foes' blades and restricts their movement, but in the end, he finds himself slashed by Jin and retreats. Yōtarō Rindō wakes up and with the help of Raijinmaru goes off to mind Hyuse, Jin notices this and runs off to go help Yotaro. Ratarikov and Gatlin head towards the Away Ship's dock, only to find themselves confronted by Tachikawa, Kazama, Konami, and Murakami. Despite putting up a considerable effort, they are overcome by Tachikawa's suicide tactic where he had Konami bisect both him and Gatlin, while Kazama took care of Ratarikov. With all members but Reghindetz retreated with the mission being considered a failure.

However, Reghindetz attempts to lure Border's attention by pretending to attack Mikado City, but Jin's forecast alerts them of the trick at hand. He is frustrated, though he is soon confronted by Hyuse and Yōtarō Rindō as they finally meet up, the former of which demands that he be taken home. Reghindetz orders Hyuse to take Yōtarō hostage to prove his allegiance to Aftokrator, but Hyuse takes things one step further and appears to stab him. Reghindetz is horrified at the excessive measure Hyuse took and informs him that Aftokrator had abandoned him, and that from the get-go, he had no intention of letting Hyuse join; even planning to kill him if necessary. However, this turns out to be a ruse; Hyuse used Scorpion to maneuver the blade around Yōtarō's body. Being tricked angers Reghindetz, who activates his trigger, Thugater. However, he is easily defeated by Hyuse and his Lampyris. Reghindetz bails out, which means every Galopoula combatant were defeated. In the ship, After the Team discussed what happened Gatlin notes that while the mission was a failure, they have plenty of time to try again as they leave orbit in a month.

Trivia

 * The buttons on their uniform seem to represent a hierarchy. For example, Gatlin has one button, indicating that he has the greatest-ranked role (#1), and Yomi, the operator, has 6 buttons, indicating that he has the lowest-ranked role. If this is the case, then the order would be:
 * 1) Gatlin
 * 2) Koskero
 * 3) Wen Sō
 * 4) Reghindetz
 * 5) Ratarikov
 * 6) Yomi
 * Their names appear to be anagrams of character names from Kiteretsu Daihakkya.
