What is World Trigger?

When a gate to another world opens in Mikado City, Earth faces an unprecedented threat from powerful aliens called Neighbors. Four years later, the mysterious Border organization defends humanity using advanced Trigger weapons. The series follows Osamu Mikumo, a Border agent, and Yuma Kuga, a mysterious transfer student who reveals himself to be a Neighbor, as they battle alien invaders and uncover secrets about the gateway.

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 used to the Neighbor’s attacks. Yuma Kuga, a transfer student, and his classmate Osamu Mikumo find themselves fighting a Neighbor that suddenly appears. Osamu, who is actually a Border agent, activates his Trigger but is unable to defeat it. This leaves Yuma to activate his own Trigger and defeat the alien. Yuma reveals that he is not part of Border and is actually a Neighbor who has transferred from the other side. (Source: Crunchyroll)
