Large-Scale Invasion

Short summary
''The large-scale invasion begins. A new Trion Warrior makes its first appearance.''

Long summary
As multiple gates open in the Danger Zone, immediate evacuation is called for any people situated near the emergence area. Osamu tells Chika to stay behind with the evacuees while he and Yūma head towards the neighbors.

In headquarters, Sawamura relays information about the positions of the Trion Warriors. Shinoda decides to send agents to the east, south, and southwest to intercept these soldiers while relying solely on Amō and Jin to control the west and northwest. Kinuta works with Fuyshima to set traps in order to delay the progression of the Trion Warriors until the arrival of the border agents.

The B-rank units Suwa Unit, Suzunari First, and Azuma Unit report in after they arrive at the scene and commence a counter-attack. After the Azuma unit kills the last Trion Warrior in their area, another Trion Warrior emerges from one of the defeated corpses.
