One day, a gate to another world suddenly opens in Mikado City. Aliens invincible to Earth’s weapons, called “Neighbors”, start coming over. Earth’s only line of defense is a mysterious group called the “Border” who are armed with weapons called “Triggers”.
Four years later, the city has recovered from initial attacks and citizens of Mikado City have started to get use to the Neighbor’s attacks.
