Aftokrator's god, who powered their star, was dying so Aftokrator sent their forces into neighboring countries to scout anyone who had a large Trion capacity, so they could be a replacement for their god.
The third Neighbor attack, or more commonly know as The Second Large-Scale Invasion happened on January 15, four and a half years after The First Large-Scale Invasion.
Over 100 gates from the Neighbor world or Neighborhood appeared in the Forbidden Zone within a minute. All of the Trion Soldiers were used in this attack, including a new type.
The aim of this attack was to gather trigger controllers from Border agents, but since A-rank and B-rank both have the Bail Out function their aim was to capture C-rank agents who didn't have the Bail Out function. They prioritized Chika because of her large Trion capacity, which could be enough to be a god.
Border successfully repelled the Neighbors who were attacking-Aftokrator however, 32 C-rank agents had been captured by the enemy, Aftokrator. Osamu had been hit badly and was in a coma. One of Aftokrator's soldiers, Hyuse was left behind, and Enedra was killed by Mira.
When the new type capture someone, they open their stomach and turn the person into a Trion Cube. If an A-rank or B-rank does not Bail Out they can still be taken by the new type.
