World Trigger

Synopsis

One day in Mikado City, a gateway to a parallel universe had opened. From it, an outbreak of aliens known as Neighbors wreaked havoc across the city with their own sophisticated technology. Suddenly, a mysterious group of people brought themselves together to repel their attacks. Soon after, Border was revealed to the public, an organization researching Neighbor technology and maintaining a defense system against the Neighbors. Its members are armed with co-opted weapons known as Triggers. Four years later, the city has recovered from initial Neighbor attacks to the point where its civilians have become used to them.
