Mikado city. 280.000 inhabitants. That day, a gate to a new world opened. Some invaders from another dimension, called "Neighbors", occupied the area near the gate, scaring the citizens to death. Human weapons seemed useless to them. The destruction of the city was a matter of time. Suddenly, a mysterious group of people appeared and faced them. A military defense organization called "Border" studied Neighbor's technology, in order to protect "this side" of the gate. While building a huge base, they established a defense system against Neighbors. 4 years later. Not so many people have left Mikado City, even if the gate is still open. High school student Osamu Mikumo is a member of the Border. That day, an exchange student moved into Osamu's class. For some reason, Yūma Kuga owned a weapon called "Trigger". Only Border's members could carry such a weapon. Osamu asked how it was possible. "I came from the other side of the gate. You call me a Neighbor" answered back Yūma as their story began.
