She also reveals that Kako Unit is aiming for the Expedition Force, and that A-Rank members get customized Triggers. Yūma declines anyways, since he plans on doing those things with his team.

On February 19, Katori Unit is doing patrols right before their Rank Battle, defeating a Mole Mod. Katori complains that this gave them a disadvantage. At the same time, their opponents were weak as they had defeated Kakizaki Unit several times before, and Tamakoma Second suffered an embarrassing loss against the top B-Rank units. Wakamura disagrees, which leads to an argument that is broken up by Sōmei. Wakamura notes Sōmei is angry, and Katori blames him for it, leading to another argument which Miura tries to break up. From the defeated Mole Mod, a new Trion Warrior, the Dog, comes out. In the Galopoula invasion ship, Gatlin notes that their security was high, which meant they probably knew an attack was imminent.

Jin senses the arrival of the invaders and recommeds that Shinoda use Pattern A, defending the HQ base. Tachikawa moves out. Jin orders Konami to tag along with Tachikawa, as he saw a future where Tachikawa would be cut down. He tells Konami that the opponents might be more difficult that anticipated.
