|Yūta Miura||Rokurō Wakamura|
During the February rank battle season, Katori Unit suffered a series of losses prior to Round 5.
Katori Unit is slated to fight Tamakoma Second and Kakizaki Unit in their Round 5 rank battle on February 19, but has defense duty right before the match, much to their captain's dismay. Katori and Wakamura begin bickering over the match, which Miura attempts to break up before Somei does it. They take down a Mole Mod. Unbeknowst to them, the Galopoula Expedition Force was monitoring the Trion Warrior and the team that defeated it, and notes that they were weaker than previous agents on duty. While preparing for their rank battle, Katori and Wakamura begin bickering over their recent streak of losses, and Katori's general attitude. Their fight is once again stopped by Somei, who announces that the battle is about to begin. Katori teleports near Yūma, and she approaches him to battle.
- The members of Katori Unit enlisted all at the same time.
- Each of the male members of this unit has an unrequited crush on a different female member, who in turn is attracted unilaterally to one of the two most famously handsome Border members.
